Abstract:

A dynamic resource allocation scheme is designed to implement user equipment(UE)-centric coordinated multi-point transmission (CoMP) in
long term evolution advanced (LTE-A) system. The decomposition of cooperate resources is used to decouple the resource among the cooperation transmission points, and the random resource allocation is used to reduce the negotiation among the cooperation transmission points. Also，a simplex local scheduling can be implemented with less resource conflict. It is proved by simulation that the scheme can effectively outperforms on both the average sector spectrum efficiency and celledge UEs’ spectrum efficiency.

Key words: coordinated multi-point transmission, resources allocation, resources collision
