Abstract:
Coordinated multi-point (CoMP) transmission for LTE-Advanced is to improve system performance, especially to enhance cell coverage and cell-edge data rate. With efficient resource allocation schemes, CoMP transmission could be a promising technology to increase system throughput. Existing frequency plan schemes on downlink CoMP transmission limit the performance of the system since they do not take the changes in traffic load as well as link quality into consideration. In this paper, an optimized scheme is proposed that each base station could allocate different proportion of bandwidth to different users'equipments (UEs) according to their traffic load and link quality, to make the system more flexible and efficient. The scheme is more effective in both system throughput and cell-edge throughput as verified through system level simulation.
