%X For uplink interference problem in ultra dense networks(UDN), a joint clustering and resource allocation scheme is proposed based on coordinated multiple point joint reception(JR-CoMP). Firstly, users and small base stations are divided into several clusters according to the uni-subband clustering. The multiple edge users in the same small cell are assigned to different user clusters. The users at the close edge of the adjacent small cell are assigned to the same cluster. The cell-center users are clustered according to the interference intensity of them to the existing base station clusters. Then, multi-sub band allocation is performed for user clusters. The user clusters containing the same small cell users are allocated different sub-bands, and the number of allocated sub-bands for each user clusters is as much as possible. Finally, the water-filling algorithm is used to allocate appropriate power to each user with the goal of maximizing the total transmission rate of the system. Simulation results show that spectral efficiency can be significantly improved by the proposed scheme.
