【Abstract】

In modern wireless mobile networks such as LTE and LTEAdvanced, performance of cell-edge users is in greet need to be improved. Coordinated multipoint transmission/reception is raised to solve the problem in 3GPP # bis 53meeting. In this paper, we present our design of (Multi-User) MU-HARQ transmission scheme in CoMP where previous studies on (SingleUser) SU-CoMP HARQ have already been submitted to ChinaCom 2011. In our design, a newly MU-HARQ transmission method is presented which will help improve target user throughput and total cell throughput under some conditions. This result is significant for 3GPP proposals.
