摘要:

CoMP的两种传输模式CoMP-JP与CoMP-CB在对回程容量需求以及提升系统性能方面具有不同的优势。针对回程容量紧缺问题,在传统以用户群为优化对象的模式选择基础上,提出了一种混合CoMP模式选择算法。该算法针对用户个体选择最佳传输模式,充分利用回程容量的同时最大化系统吞吐量。仿真结果表明,所提出的模式选择算法能有效提升系统性能,并且随着用户数的增加,其性能增益会更高。

Abstract:

CoMP-JP and CoMP-CB are two transmission modes for coordinated multi-point and have different gains incapacity requirements and improving the system performance. Aimed at the backhaul capacity shortage, a hybrid CoMPmode selection algorithm was proposed under the traditional transmission mode selection based on the user’s group. The algorithm selects the optimal transmission mode for individual user. It can be full use of the backhaul capacity and achieve the maximal system throughput. Simulation results show that the proposed algorithm enhanced the system performance under the limited backhaul capacity at a large extent, and with the increase of users, the higher performance gain.

Key words: hybrid cooperative transmission, backhaul capacity, mode selection
