The invention provides a physical random access resource processing method and a device. The method comprises steps: a base station judges whether physical random access resources exist in downlink subframes after dynamic uplink-downlink subframe ratio adjustment; when the judgment result is positive, the base station processes the downlink subframes with the physical random access resources into uplink subframes; and/or, when the judgment result is negative, the base station processes the downlink subframes without the physical random access resources into downlink subframes. Thus, the problem that in order to avoid interference between new UE and old UE, as a random physical access channel configuration index is greatly limited, difficulty of network planning is greatly increased can be solved, and effects of configuration limitation of the random access resources when the subframe ratio adjustment technology starts can be effectively reduced and the network planning difficulty is simplified are achieved.

Physical accidental access-in resource processing method and device

Technical field

The present invention relates to the communications field, in particular to a kind of physical accidental access-in resource processing method and device.

Background technology

In Long Term Evolution (Long Term Evolution, referred to as LTE) system, LTE time division duplex (Time Division Duplex, referred to as TDD) have employed frame type 2(Frame structure type2).In frame type 2, each radio frames length is 10ms, and comprising 10 length is the subframe of 1ms, can being configured to up, descending as required or using as special subframe of each subframe.The uplink and downlink subframe proportion relation defined in TS36.211 in current agreement is as shown in table 1 below:

Table 1: uplink and downlink subframe proportioning

As can be seen from the above table, the uplink and downlink subframe proportioning that 7 kinds (configuration 0 to 6) is different is defined in current agreement.In early days in LTE system, the uplink and downlink subframe proportioning that each community uses is static configuration, and broadcasts in system message.UE knows the uplink and downlink subframe proportioning of community by receiving system message.When needs carry out Stochastic accessing, UE is according to the PRACH configuration index (PRACH Configuration Index) of broadcasting in system message equally, form (as shown in table 2 below) in vlan query protocol VLAN TS36.211 obtain the PRACH resource under corresponding uplink and downlink subframe proportioning specific configuration information (concrete configuration is made up of a four-tuple, indicate PRACH resource time, frequency domain position information etc.).

Table 2:PRACH resource time-frequency domain mapping relations table

As can be seen from the above table, same PRACH configuration index indicates different PRACH resource distribution 4 tuples (namely indicating different PRACH resource locations) in different uplink and downlink subframe proportionings.

Along with the development of LTE technology and the expansion of Commercial scale, fixing uplink and downlink subframe proportioning is difficult to meet the need of market gradually.In LTE disposes, operator find uplink and downlink service traffics in community along with the change of time be dynamic change, subframe proportioning that is fixing or slowly change (by deleting, building the uplink and downlink subframe proportioning of the mode reconfiguring cell such as community, and notifying UE by system message) is used to be difficult to effectively use Radio Resource in the cell.Therefore, the dynamic proportioning adjustment technology of TDD subframe is introduced in LTE TDD technology, under this technology, the part sub-frame of uplink in the uplink and downlink configuration broadcasted in system message by the change of physical layer signaling dynamic notification UE community uplink and downlink subframe proportioning, can be used (in current 7 kinds of uplink and downlink subframe proportionings switching at runtime) as descending sub frame by eNB.

The dynamic subframe proportioning adjustment technology that early version UE due to existing network cannot support redaction agreement to introduce, in order to the existing UE of compatibility, existing UE still use the uplink and downlink subframe proportioning broadcasted in system message.And do not support the UE of subframe proportioning dynamic conditioning in order to avoid the existing UE(of early version) new UE(is supported to the UE of subframe proportioning dynamic conditioning) interference, network side can not dispatch early version UE on the former sub-frame of uplink that dynamic conditioning is descending.For PRACH resource, because the transmission of PRACH signal is determined voluntarily by UE opportunity, and according to the uplink and downlink subframe proportioning in system message with economic PRACH configuration index select PRACH to use time, frequency domain resource, in order to avoid early version UE is to the interference of redaction UE, network side needs to ensure that the PRACH resource place subframe that early version UE calculates according to table 2 remains sub-frame of uplink (not being dynamically adjusted as descending) after dynamic conditioning by configuration PRACH configuration index.This restriction greatly reduces PRACH configuration index available in community, proposes very large challenge to the planning of PRACH access-in resource in network planning optimization.

Therefore, in the related for avoiding the interference between new and old UE, owing to significantly limit random physical access channel configuration index, thus cause the difficulty considerably increasing the network planning.

In addition, when whether the descending sub frame after base station judges ratio of uplink subframe to downlink subframe dynamic conditioning has physical accidental access-in resource to exist, the descending sub frame that this base station carries out judging is: being designated as in the sub-frame of uplink proportioning broadcasted in system message is up, but after dynamic conditioning, change into descending subframe, or, all descending sub frames after ascending-descending subframes dynamic conditioning.

In view of problem existing in correlation technique, in conjunction with the configuration processing method of random access resource during ratio of uplink subframe to downlink subframe dynamic conditioning in the system for time division multiplex communication that above-described embodiment and preferred implementation provide, by the method, advantageously reduce the configuration difficulty of random access resource when gap proportioning dynamic development adjustment starts.Based on the application, from network side and terminal UE side, the concrete enforcement to the program is described in further detail respectively below.

Network side:

During this subframe dynamic conditioning, random access resource processing method, comprises the steps:

Whether the descending sub frame after step S1, eNB judge dynamic conditioning there is random access resource to exist;

Step S2, if judge descending sub frame has random access resource exist, then will there is this descending sub frame of random access resource as (or being adjusted to) sub-frame of uplink in eNB.Otherwise if descending sub frame does not have random access resource, then eNB thinks that (or determination) this subframe is descending sub frame.

Wherein, above-mentioned said dynamic conditioning is, eNB adjusts uplink and downlink subframe proportioning by physical layer signaling or medium education (Media AccessControl, referred to as MAC) layer signaling UE.

The resource that above-mentioned random access resource uses for UE transmission PRACH prefix (preamble).

Above-mentioned random access resource calculates according to the PRACH configuration index of broadcasting in the ascending-descending subframes of cell proportioning broadcasted in system message and system message.And whether contain descending sub frame in judging the subframe that " whether descending sub frame having random access resource exist " implication uses for the above-mentioned random access resource calculated.Implication is that the above-mentioned random access resource calculated contains descending sub frame " descending sub frame to have random access resource exist "." descending sub frame does not have random access resource " implication is that the above-mentioned random access resource calculated does not comprise descending sub frame.

Wherein, the implication of above-mentioned " eNB by this subframe as sub-frame of uplink " comprise following one of at least: eNB can not send the down physical channels such as PDCCH, PDSCH in this subframe; ENB can receive physical uplink control channel (Physical Uplink Control CHannel in this subframe, referred to as PUCCH) Physical Uplink Shared Channel (Physical uplink sharedchannel, referred to as PUSCH) and PRACH preamble, if this sub-frame configuration random access resource (for sending the resource of PRACH preamble).

The implication of " eNB thinks that this subframe is descending sub frame " comprise following one of at least: eNB can not receive the physical channels such as PUCCH, PUSCH and accidental access signal (PRACH preamble) in this subframe; ENB can send the physical channels such as PDCCH, PDSCH in this subframe.

It should be noted that, if random access resource sequentially (such as: periodically) appear on certain descending sub frame after dynamic conditioning, then eNB only thinks when random access resource occurs that this subframe is sub-frame of uplink; And Stochastic accessing is not appeared to other moment of this subframe, think that this subframe is descending sub frame.

In addition, if random access resource sequentially (such as: periodically) appear on certain descending sub frame after dynamic conditioning, then eNB thinks that this subframe is sub-frame of uplink.

Wherein, in above-mentioned steps S2, judge to carry out before being not limited in each subframe moment reaches.Judge to can be, but not limited to carry out in the following moment: judge before each subframe arrives; Namely the judgement to each subframe is completed after dynamic-configuration uplink and downlink subframe relation; To the judgement of subframe uplink and downlink situation during various possible dynamic ascending-descending subframes relation after configured the set of potential dynamic conditioning ratio of uplink subframe to downlink subframe by RRC information.

Wherein, the scope of carrying out the descending sub frame judged is needed to be in step S2: to be designated as up in the ratio of uplink subframe to downlink subframe of broadcasting in system message, but after dynamic conditioning, to change into descending subframe.

End side:

During this subframe dynamic conditioning, random access resource processing method, comprises the steps:

Whether the descending sub frame after step S1, UE judge dynamic conditioning there is random access resource to exist;

Step S2, if judge descending sub frame has random access resource exist, then UE by this subframe as (or being adjusted to) sub-frame of uplink.Otherwise if descending sub frame does not have random access resource, then UE thinks that (determination) this subframe is descending sub frame.

Wherein, the dynamic conditioning in above-mentioned steps S1 is, UE receives the uplink and downlink subframe proportioning adjustment order from eNB by physical layer signaling or MAC layer signaling, and adjusts according to order.

The resource that in step S1, random access resource uses for UE transmission PRACH preamble.

In step S1, random access resource time-domain position calculates according to the PRACH configuration index of broadcasting in the ascending-descending subframes of cell proportioning broadcasted in system message and system message.

Judge in step S1 whether " whether descending sub frame having random access resource exist " implication contains descending sub frame in the subframe that uses according to the above-mentioned random access resource calculated.

Implication is " descending sub frame to have random access resource exist " in step S2: contain descending sub frame in step S2 according to the above-mentioned random access resource calculated.In step S2, " descending sub frame does not have random access resource " implication is: do not comprise descending sub frame in rapid S2 according to the above-mentioned random access resource calculated.

Wherein, in step S2 the implication of " UE by this subframe as sub-frame of uplink " comprise following one of at least: UE can not receive the down physical channels such as PDCCH, PDSCH in this subframe; UE can send PRACH preamble in this subframe, if this subframe is configured with random access resource (PRACH preamble resource requirement).

Wherein, in step S2 the implication of " UE thinks that this subframe is descending sub frame " comprise following one of at least: UE can not send the physical channels such as PUCCH, PUSCH and accidental access signal (PRACH preamble) in this subframe; UE can receive the down physical channels such as PDCCH, PDSCH in this subframe.

Wherein, describe in step S2, if random access resource periodically appears on certain descending sub frame after dynamic conditioning, then UE only thinks when random access resource occurs that this subframe is sub-frame of uplink; And Stochastic accessing is not appeared to other moment of this subframe, think that this subframe is descending sub frame.

Wherein, describe in step S2, if random access resource periodically appears on certain descending sub frame after dynamic conditioning, then UE thinks that this subframe is sub-frame of uplink.

Wherein, judge in step S2 to carry out before being not limited in each subframe moment reaches.Judge to can be, but not limited to carry out in the following moment: judge before each subframe arrives; The judgement to each subframe is completed after the order receiving dynamic-configuration uplink and downlink subframe relation; To the judgement of subframe uplink and downlink situation during various possible dynamic ascending-descending subframes relation after received the set of potential dynamic conditioning ratio of uplink subframe to downlink subframe by RRC information.

Wherein, need in above-mentioned steps S1 judge descending sub frame be according to system message broadcast ratio of uplink subframe to downlink subframe be up, but change descending descending sub frame after dynamic conditioning into; Or be descending all descending sub frames after dynamic conditioning.

By such scheme, can effectively reduce and after the dynamic uplink and downlink subframe proportioning adjustment of configuration, the use of PRACH configuration index be limited, thus reduce the difficulty of network planning optimization.

Below the preferred embodiment of the present invention is described.

Preferred embodiment one (eNB side):

Figure 10 is the method flow diagram according to the preferred embodiment of the present invention one, and as shown in Figure 10, this flow process comprises the steps:

Step S1002, eNB is in cell a by uplink and downlink subframe proportioning (the up-downgoing proportioning index of broadcasting in system message is 0, and the uplink and downlink subframe proportioning of index 0 correspondence can find in Table 1) and the Stochastic accessing configuration index of system message broadcast cell.The position calculating random access resource according to the uplink and downlink subframe proportioning broadcasted in system message and random access resource configuration index is positioned at that subframe 4(is follow-up is abbreviated as sf4), and random access resource appears in radio frames that System Frame Number is odd number (in continuous two 10ms radio frames, only have in the subframe 4 of a radio frames and have random access resource).

Step S1004, eNB send RRC reconfiguration message to UE, and message indicates this community to start uplink and downlink subframe proportioning dynamic adjustment function, and receive and reshuffled message from UE.

Step S1006, eNB send the order of uplink and downlink subframe dynamic conditioning by physical layer signaling or MAC layer signaling to UE, indicate ratio of uplink subframe to downlink subframe to be adjusted to index 3 in order.ENB judges for index 3 and the random access resource position calculated.In uplink-downlink configuration index 3, compared with the index 0 of broadcasting in system message, sf6/7/8/9(and subframe 6/7/8/9) from up become descending, because random access resource is at sf4, therefore sf6/7/8/9 does not have random access resource, eNB thinks that dynamic conditioning is that after ratio of uplink subframe to downlink subframe 3, sf6/7/8/9 is descending sub frame.

Step S1008, eNB send the order of uplink and downlink subframe dynamic conditioning by physical layer signaling or MAC layer signaling to UE, indicate ratio of uplink subframe to downlink subframe to be adjusted to index 4 in order.When uplink-downlink configuration index is 4, compared with index 0, sf4/6/7/8/9 all becomes descending, and owing to containing random access resource in subframe sf4, therefore eNB thinks that sf6/7/8/9 is descending under this arrangement, and sf4 is up.

Wherein, when eNB thinks that certain subframe is up, eNB can not dispatch the down channels such as PDCCH PDSCH in this subframe, but can receive the up channel such as PRACH preamble and PUCCH PUSCH in this subframe.When eNB thinks that certain subframe is descending sub frame, eNB can send the down channels such as PDCCH PDSCH in this subframe, but can not receive lower channel on PRACH preamble PUCCH PUSCH etc. in this subframe.

Preferred embodiment two (eNB side):

Based on the flow process that Figure 10 is similar:

ENB is in cell a by uplink and downlink subframe proportioning (the up-downgoing proportioning index of broadcasting in system message is 0, and the uplink and downlink subframe proportioning of index 0 correspondence can find in Table 1) and the Stochastic accessing configuration index of system message broadcast cell.The position calculating random access resource according to the uplink and downlink subframe proportioning broadcasted in system message and random access resource configuration index is positioned at that subframe subframe 4(is follow-up is abbreviated as sf4), and random access resource appears in radio frames that System Frame Number is odd number (in continuous two 10ms radio frames, only have in the subframe 4 of a radio frames and have random access resource).

The RRC reconfiguration message that eNB sends to UE, carries the uplink and downlink subframe proportioning that may occur in dynamic conditioning in message: up-downgoing proportioning index 3 and up-downgoing proportioning index 4, and receives and reshuffled message from UE.Now, eNB, for index 3 and index 4, judges with the random access resource position calculated.In uplink-downlink configuration index 3, compared with the index 0 of broadcasting in system message, sf6/7/8/9 from up become descending, because random access resource is at sf4, therefore sf6/7/8/9 does not have random access resource, eNB thinks that sf6/7/8/9 is descending under this uplink-downlink configuration; And when uplink-downlink configuration index is 4, compared with index 0, sf4/6/7/8/9 all to become descending, because System Frame Number is contain random access resource in sf4 subframe in the radio frames of odd number, therefore eNB thinks under this arrangement, when System Frame Number is even number, sf4/6/7/8/9 is descending, and when System Frame Number is odd number, sf6/7/8/9 is descending, sf4 is up.

ENB sends the order of uplink and downlink subframe dynamic conditioning to UE, indicates ratio of uplink subframe to downlink subframe to be adjusted to index 3 in order.ENB, according to the judged result in above-mentioned steps, thinks that sf6/7/8/9 is descending sub frame.

ENB sends the order of uplink and downlink subframe dynamic conditioning to UE, indicates ratio of uplink subframe to downlink subframe to be adjusted to index 4 in order.According to the judged result in 2, eNB thinks that sf4/6/7/8/9 is descending, and when System Frame Number is odd number, sf6/7/8/9 is descending sub frame, and sf4 is sub-frame of uplink when System Frame Number is even number.

Wherein, when eNB thinks that certain subframe is up, eNB can not dispatch the down channels such as PDCCH PDSCH in this subframe, but can receive the up channel such as PRACH preamble and PUCCH PUSCH in this subframe.When eNB thinks that certain subframe is descending sub frame, eNB can send the down channels such as PDCCH PDSCH in this subframe, but can not receive lower channel on PRACH preamble PUCCH PUSCH etc. in this subframe.

Preferred embodiment three (UE side):

Based on the flow process that Figure 10 is similar:

UE resides in community A, and from the A system message of community, obtain uplink and downlink subframe proportioning (the up-downgoing proportioning index of broadcasting in system message is 0, and the uplink and downlink subframe proportioning of index 0 correspondence can find in Table 1) and the Stochastic accessing configuration index of community.UE is positioned at according to the position that the uplink and downlink subframe proportioning received in system message and random access resource configuration index calculate random access resource that subframe 4(is follow-up is abbreviated as sf4), and random access resource appears in radio frames that System Frame Number is odd number (in continuous two 10ms radio frames, only have in the subframe 4 of a radio frames and have random access resource).

UE receives the RRC reconfiguration message from eNB, and message indicates this community to start uplink and downlink subframe proportioning dynamic adjustment function, and has reshuffled message to eNB feedback.

UE receives the uplink and downlink subframe dynamic conditioning order from eNB, indicates ratio of uplink subframe to downlink subframe to be adjusted to index 3 in order.UE judges for index 3 and the random access resource position calculated.In uplink-downlink configuration index 3, compared with the index 0 of broadcasting in system message, sf6/7/8/9 from up become descending, because random access resource is at sf4, therefore sf6/7/8/9 does not have random access resource, UE thinks that sf6/7/8/9 is descending sub frame under this uplink-downlink configuration.

UE receives the uplink and downlink subframe dynamic conditioning order from eNB, indicates ratio of uplink subframe to downlink subframe to be adjusted to index 4 in order.When uplink-downlink configuration index is 4, compared with index 0, sf4/6/7/8/9 all becomes descending, and owing to containing random access resource in subframe sf4, therefore UE thinks that sf6/7/8/9 is descending under this arrangement, and sf4 is up.

Wherein, if UE thinks that certain subframe is upper and lower subframe, then UE can send PRACH preamble(accidental access signal in this subframe) and PUSCH the uplink physical channel such as PUCCH; If UE thinks that certain subframe is upper and lower subframe, then UE can receive in this subframe PDCCH the physical channel such as PDSCH.

Preferred embodiment four (UE side):

Based on the flow process that Figure 10 is similar:

UE resides in community A, and from the A system message of community, obtain uplink and downlink subframe proportioning (the up-downgoing proportioning index of broadcasting in system message is 0, and the uplink and downlink subframe proportioning of index 0 correspondence can find in Table 1) and the Stochastic accessing configuration index of community.UE is positioned at according to the position that the uplink and downlink subframe proportioning received in system message and random access resource configuration index calculate random access resource that subframe 4(is follow-up is abbreviated as sf4), and random access resource appears in radio frames that System Frame Number is odd number (in continuous two 10ms radio frames, only have in the subframe 4 of a radio frames and have random access resource).

UE receives the RRC reconfiguration message from eNB, carries the uplink and downlink subframe proportioning that may occur in dynamic conditioning in message: up-downgoing proportioning index 3 and up-downgoing proportioning index 4, and reshuffled message to eNB feedback.Now, UE, for index 3 and index 4, judges with the random access resource position calculated.In uplink-downlink configuration index 3, compared with the index 0 of broadcasting in system message, sf6/7/8/9 from up become descending, because random access resource is at sf4, therefore sf6/7/8/9 does not have random access resource, UE thinks that sf6/7/8/9 is descending under this uplink-downlink configuration; And when uplink-downlink configuration index is 4, compared with index 0, sf4/6/7/8/9 all to become descending, because System Frame Number is contain random access resource in sf4 subframe in the radio frames of odd number, therefore UE thinks under this arrangement, when System Frame Number is even number, sf4/6/7/8/9 is descending, and when System Frame Number is odd number, sf6/7/8/9 is descending, sf4 is up.

UE receives the uplink and downlink subframe dynamic conditioning order from eNB, indicates ratio of uplink subframe to downlink subframe to be adjusted to index 3 in order.UE, according to the judged result in 2, thinks that sf6/7/8/9 is descending sub frame.

UE receives the uplink and downlink subframe dynamic conditioning order from eNB, indicates ratio of uplink subframe to downlink subframe to be adjusted to index 4 in order.According to the judged result in 2, UE thinks that sf4/6/7/8/9 is descending, and when System Frame Number is odd number, sf6/7/8/9 is descending sub frame, and sf4 is sub-frame of uplink when System Frame Number is even number.

Wherein, if UE thinks that certain subframe is upper and lower subframe, then UE can send PRACH preamble(accidental access signal in this subframe) and PUSCH the uplink physical channel such as PUCCH; If UE thinks that certain subframe is upper and lower subframe, then UE can receive in this subframe PDCCH the physical channel such as PDSCH.
