Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of distribution method and terminal CQI (Channel Quality Information, channel quality indication) value feedback device of cell frequency resources.
Background technology
The reduction presence of intercell interference is an important goal of cellular system design to the influence of performance in wireless communication systems.If presence of intercell interference is serious, will greatly reduces power system capacity, the particularly transmittability at cell edge terminal, thereby have influence on covering power and terminal use's impression of system.
In order to overcome presence of intercell interference; Intel Company has proposed a kind of AFR based on price mechanism (Adaptive Frequency Reuse; Adaptive frequency reuse) scheme; Through adjusting the price (cost) that each reuses subband in the set (Reuse Set), give the terminal with the different sub-band frequency resource allocation, thereby reduce presence of intercell interference intensity.The cardinal principle of this scheme is: at first, all available frequency resources are divided into 7 subband set close W: [W

3, frequency duplex factor as one is 3, i.e. Reuse3.High power (P of each cell selecting
1) sets of subbands, two other sets of subbands adopts low-power (P
2), and guarantee neighbor cell high power sets of subbands mutually orthogonal.In the process of dividing frequency resource, at first, the cost of base station each each sets of subbands of terminal broadcast in the sub-district; Then, each terminal is through the SE (Spectral Efficiency, spectrum efficiency) of each sets of subbands of channel estimating prediction, afterwards through formula nSE
i=SE
i/ Cost
iThe weighting SE (nSE) of each sets of subbands is calculated in (i=1,2,3), and the CQI value that M (1≤M≤3) subband set that result of calculation is maximum is closed feeds back to the base station; At last; The base station is each terminal distribution frequency resource according to the CQI value of all terminal feedback, and when needing the cost value of each sets of subbands of self adaptation adjustment, accomplishes corresponding adjustment and make system reach the state of an optimum; When preset cost broadcast cycle arrives, repeat aforesaid operations.
Fig. 2 is a simulation result sketch map of selecting the feedback sets of subbands according to the cost of sets of subbands; It is divided and the power division situation based on cell frequency resources shown in Figure 1; " * " represents lower powered sets of subbands, and " zero " represents high-power sets of subbands, and abscissa is represented SINR (the signal to interference noise ratio of cell terminal; Signal to Interference plus Noise Ratio), ordinate is represented low power sub-bands set cost value.As can be seen from Figure 2; Continuous reduction along with low power sub-bands set cost value; Most of SINR selects at higher terminal (being called center terminal) the CQI value of the lower powered sets of subbands of feedback Reuse3; The CQI value of the high-power sets of subbands of feedback Reuse3 is selected at the terminal (being called edge termination) that most of SINR is lower; But some edge terminations are selected the CQI value of the lower powered sets of subbands of feedback Reuse3, and some center terminal are selected the CQI value of the high-power sets of subbands of feedback Reuse3.This feedback result is irrational to the edge termination of the CQI value of feeding back lower powered sets of subbands; The base station is the further channel quality that worsens these edge terminations of terminal distribution frequency resource meeting according to this feedback result, and this situation can not improve along with the variation of sets of subbands cost value.
