IEEE802.16j中的协作中继机制

Cooperative Relay Mechanism in IEEE 802.16j

蜂窝网络中配置中继节点可以提高系统容量和小区覆盖范围。IEEE成立802.16j工作组研究移动多跳中继。首先介绍了协作中继的基本概念,然后讨论了802.16j中定义的三种协作分集机制:协作源端分集、协作发送分集和协作混合分集。最后,给出了实现协作中继的四个步骤。

Deploying relay nodes in cellular networks will improve the system capacity and extend the coverage, IEEE 802.16j task group was set up to study mobile multihop relay, Firstly, the fundamental concepts of cooperative relaying are introduced, and then three mechanisms of cooperative relaying are discussed, i.e. cooperative source diversity, cooperative transmit diversity, and cooperative hybrid diversity. Finally, four steps for cooperative relaying are presented.
