混合时延约束下扇区化蜂窝网络的复用增益域

Multiplexing Gain Region of Sectorized Cellular Networks with Mixed Delay Constraints

Homa Nikbakht, Michèle Wigger, Shlomo Shamai

摘要:

当相邻移动用户和基站都可以在速率受限链路上协作时,考虑了具有混合时延约束的扇区化六边形模型。每个消息都是独立的“快”和“慢”比特的组合,其中前者受到严格的延迟约束,并且不能从合作中获益。推导了复用增益区域的内、外边界。所得到的结果表明,对于小的合作prelog或适度的“快速”复用增益,整体性能(和复用增益)几乎没有下降的严格的延迟约束的“快速”位。对于大的协作前日志和大的“快速”复用增益,将“快速”复用增益增加$Δ$是以将和复用增益减少$3 Δ$为代价的。

英文摘要:

The sectorized hexagonal model with mixed delay constraints is considered when both neighbouring mobile users and base stations can cooperate over rate-limited links. Each message is a combination of independent "fast" and "slow" bits, where the former are subject to a stringent delay constraint and cannot profit from cooperation. Inner and outer bounds on the multiplexing gain region are derived. The obtained results show that for small cooperation prelogs or moderate "fast" multiplexing gains, the overall performance (sum multiplexing gain) is hardly decreased by the stringent delay constraints on the "fast" bits. For large cooperation prelogs and large "fast" multiplexing gains, increasing the "fast" multiplexing gain by $Δ$ comes at the expense of decreasing the sum multiplexing gain by $3 Δ$.
