研究了时变互易信道下时隙无线环网的全局信道状态信息。最大和平均陈旧的全球CSI的下界推导，并开发出有效的协议，实现的界限。考虑了两种极端情况，即（i）一次一个节点进行传输，或者（ii）一次最大数量的节点在没有冲突的情况下进行传输。此外，每个分组传播的CSI的量在两个极端之间变化。仿真结果证实了分析和量化老化的网络参数。
This paper studies global channel state information (CSI) in time-slotted wireless ring networks with time-varying reciprocal channels. Lower bounds on maximum and average staleness of global CSI are derived, and efficient protocols that achieve the bounds are developed. Two extreme scenarios are considered with either (i) one node transmitting at a time or (ii) the maximum number of nodes transmitting at a time without collisions. In addition, the amount of CSI disseminated per packet is varied between two extremes. Simulation results confirm the analysis and quantify staleness in terms of the network parameters.
