LTE网络端MAC状态研究与设计

Research and design on the state of LTE network MAC layer

针对目前LTE系统网络端MAC子层状态划分的不明确性,提出了在LTE系统通信过程中网络端MAC层状态划分的方案。该方案将网络端MAC层划分为4个状态,设计了状态转移过程及随机接入流程,由此实现了MAC状态转移方案。通过TTCN与SDL协仿真的测试,证明了状态转移及随机接入流程设计的正确性,为LTE系统的通信实现提供有效方案。

Aiming at the state of the current LTE system network side MAC layer is uncertain, the network MAC layer state division scheme is presented in the process of LTE system communication. In this scheme, the network side MAC layer is divided into four states, the state transfer process and random access process designed thus achieved MAC state transition scheme. TTCN and SDL co simulation test proves state transition and random access process design is feasible, providing an effective program for the LTE system communication.
