：针对 CoMP 系统中协作集选择问题，提出了一种以天线为基本单位的协作集双向选择算法。该算法在用户侧进行待选协作集生成，在网络侧利用用户反馈的待选协作集及与之相关的信道状态信息，选择与用户进行协作的天线，完成终选协作集的生成。该算法对用户侧和网络侧进行分别处理，灵活性高，能够有效降低空中接口和回程链路传输的数据量，提高系统资源利用率；同时，算法充分利用了 CoMP 系统多天线的优势，提升了系统性能。仿真表明，本文所提算法能够以较低的计算复杂度获得与穷举算法相近的系统容量性能。

Aiming at the problem of generating the cooperation sets, an antenna based two-way cooperative gener-ating algorithm is proposed. In this algorithm, the pre-selection sets are generated by user equipment (UE), and then these sets are fed back to the processing center with corresponding channel information. With these fed back infor-mation, the processing center allocates antennas on base stations to users to form the final selection sets. The UEs and the base stations are treated separately, thus it is possible to apply different algorithms in different situations on each side to obtain the optimized system performance. The proposed algorithm is able to reduce the amount of data transmit-ted in the air and backhaul, meanwhile the advantages of multiple antennas are taken, and the system performance is improved. Simulations indicate that the proposed algorithm can obtain similar system performance with that of the ex-haustive algorithm.
