Description
The application is that the application number of submitting on June 15th, 2007 is 200710126184.6, and denomination of invention is divided an application for the application for a patent for invention of " launching technique of frequency-hopping signaling, frequency-hopping mode and dispatch collocation method ".
Technical field
The present invention relates to the frequency modulation method of single carrier-frequency division multiple access system uplink multi-users among the 3GPP LTE of the communications field, particularly, relate to a kind of launching technique and frequency-hopping mode and dispatch collocation method of frequency-hopping signaling.
Background technology
In order to satisfy demand to the mobile communication of continuous development, there are some basic demands aspect the selection of uplink radio transmission technology, for example, support scalable bandwidth, moderate PAPR/CM (peak-to-average force ratio/cubic meter) and the orthogonality etc. that guarantees uplink.Because single carrier transmission scheme (for example, single-carrier frequency division multiple access (SC-FDMA)) has lower PAPR/CM,, therefore become the basic candidate scheme of present Long Term Evolution (LTE) uplink so can improve the validity of power and expand the coverage area.
Data transmission scheme based on the subcarrier mapping mode has two kinds, that is, and and distributed frequency division multiple access (DFDMA) and centralized frequency division multiple access (LFDMA).Because the scheme based on distributed sub-carrier allocation has higher susceptibility to the frequency mistake in up link, so exist to uplink power control have relatively high expectations, problem such as channel estimating performance is relatively poor, abandoned at present by the research of LTE, but be based on the scheme of centralized subcarrier allocation, still can obtain in the mode of frequency hopping distributed sub-carrier the advantage of intrinsic frequency diversity.Used frequency hopping (Frequency Hopping) among the single carrier transmission scheme LFDMA-FH that most of manufacturer is recommended (LFDMA-frequency hopping), both can guarantee good channel estimating performance, frequency diversity gain can be obtained again, and cell interference diversity gain can be obtained.

Based on semi-stability scheduling described above, the embodiment of the invention combines semi-stability scheduling and specific frequency-hopping mode, has proposed a kind of hopping scheme based on semi-stability, describes embodiments of the invention in detail hereinafter with reference to accompanying drawing.
Method embodiment one
A kind of launching technique of the frequency-hopping signaling based on the semi-stability scheduling is provided in the present embodiment.
As shown in Figure 2, comprise according to the launching technique of the frequency-hopping signaling of present embodiment: step S202, the base station is user's preassignment (predefine) frequency parameter, and the user carries out the frequency hopping emission according to frequency parameter; Step S204, when user's request scheduling, the user uses preallocated frequency parameter, and perhaps using the base station is that the new frequency parameter of its distribution carries out the frequency hopping emission.
Preferably, on the basis of above-mentioned processing shown in Figure 2, may further include following processing: when the base station detects user's free of data emission, or user's request is not when launching data, and the user stops frequency hopping.
Wherein in
step202, the base station is that user's preassignment frequency parameter can need not the request by the user after the user links with base station foundation, notifies the user by a broadcasting or
layer3 means of signaling.
In user's frequency hopping process, the base station can pro-active intervention frequency hopping process, for example, in step S202 or step S204, the base station can use single user's dispatch to change the frequency-hopping resource that the user uses by force, that is, force users is not used original resource and is changed the somewhere resource (pressure change frequency-hopping mode as shown in Figure 5) of using other into.
Wherein, in step S204, in the user is the group during user, group scheduling signaling (Group schedule Signaling is adopted in the base station, also can be called group's signaling) notify the user with user's schedule information or scheduling authorization (schedule grant), in this case, with the user's frequency bandwidth demand information in user's schedule information or the scheduling authorization or Adaptive Modulation (AMC) information as frequency parameter.In addition, user's schedule information or scheduling authorization can also comprise the information of relative position skew in the customer group, and equally can be with this information as frequency parameter.
