| 摘 要： | 具有中继功能的802.16j协议,是为了增加基于802.16e网络的覆盖能力和容量.新的网络结构在原有网络基础上加入了中继站来进行中继通信,既可以增加本小区网络的覆盖范围,又可以解决非视距传输问题.针对加入新的中继站,带宽资源的控制和管理不再由基站统一管理,IEEE标准制定工作组定义了两种控制方式--集中式和分布式,但没有定义两种控制模式的适用范围.通过分析和仿真说明,集中式适用于拓扑简单的网络,可以提高小区资源利用率.而分布式适用于复杂网络,从而减少信令交互次数和延时.

| Abstract: | Being an evolution of IEEE 802.16e,IEEE 802.16j mobile multi-hop relay is proposed to gain coverage extension and throughput enhancement.Relay Station(RS) has been added in the new network to extend the coverage as well as to improve Non-Line-of-Sight.However,these new RSs involve many new problems.For example,the bandwidth resource is not allocated by Base Station(BS) only.As a result,Centralized and Distributed bandwidth request and allocation mechanisms are proposed in 802.16j Draft Standard.However,the ... |
