摘要:

提出了一种新的基于协作多点传输和接收（CoMP）技术的多发随机接入流程，并根据随机接入的目的和业务类型设计了接入优先级，在此基础上设计了一种新的随机接入方案，对不同类型的随机接入请求提供不同的接入机制，以保证边缘用户的接入性能和满足不同业务的QoS需求。仿真结果表明，与LTE标准随机接入方案相比，该方案对系统整体接入性能略有提高，且大大提高了边缘高优先级用户的接入性能。

Abstract:

A new multiple random access process is proposed based on Coordinated Multi-point (CoMP) transmission and reception. And the access priority is design ed according to the purpose of random access and the type of service. On this ba sis, a new random access scheme is discussed. This scheme provides different acc ess mechanisms to different types of random access requests, and ensures the edg e users′ access performances and the QoS requirements of different services. Si m ulation results show that, compared with the LTE standard random access program, the overall system access performances increase slightly, and the edge high-pri ority access performances increase greatly.

Key words: LTE-A random access CoMP access priority backoff algorithm
