    Abstract: 该文首次在多天线多信道802.11无线网状网中提出了时频信道的概念.时频信道是通过在时间和频率两个维度划分无线资源取得的.这种划分方法增加了信道数量,使信道划分更加精细,为提高系统的信道利用率做了准备.在时频信道的基础上,提出了准动态信道分配算法.该算法可以和现有的固定信道分配算法结合,实现准动态信道分配,根据链路上负载变化,取得最大的吞吐量.该算法先根据固定信道分配算法为各链路分配相同数量的时频信道,剩余部分当作公共信道.在通信过程中,各链路首先使用分配给自己的信道和空闲的公共信道.如果分配给一个链路的信道不够,且别的链路上的信道有空闲,该链路还可以暂时使用这些空闲信道.理论分析和仿真结果证明该算法可以有效提高系统的吞吐量.
