摘要

By introducing the concept of the network serving user, user-centric ultra dense network (UUDN) is proposed as a promising approach of 5G. The access point group (APG), which consists of one or several APs, is dynamically organized to serve each user in UUDN. The APs within an APG need to cooperate to serve a user, and then the resource allocation is much different compared to that in traditional cellular networks. How to effectively allocate the resource among APs within an APG is a crucial issue to serve a user. Considering user's different service flow and system energy efficiency, in this paper we propose a service-driven resource allocation scheme for UUDN to maximize the energy efficiency. This scheme can jointly allocate power and sub-carriers among the serving APs to satisfy user's demand. Besides, it adjusts the number of APs dynamically to serve users according to their service flow. Simulation results show that compared with the existing algorithms, the proposed scheme has better performance in satisfying user's demand and improving system energy efficiency.
