Abstract

In this paper, a novel approach to minimising intercellular interference and maximising spectral-efficiency in a TDMA (time division multiple access) TDD (time division duplexing) cellular network with 100% frequency re-use and unequal traffic load asymmetry in different cells is presented. A new distributed medium access control (MAC) protocol called CSTDMA (carrier sensing time division multiple access) and a modified PRMA (packet reservation multiple access) protocol are applied and their performance is compared against state-of-the-art MAC protocols. CSTDMA TDD employs a modified busy-tone broadcast/channel-sensing mechanism, while PRMA (packet reservation multiple access) employs a handshaking procedure. Results show significant improvements in system capacity and spectral-efficiency from the application of this novel approach compared to the state-of-the-art, especially with the CSTDMA TDD approach, which overall achieves the best performance, offering more than 3 to 4 times the capacity and system spectral-efficiency of the traditional methods

第4代TDMA TDD蜂窝移动无线通信中的分布式蜂窝间干扰管理

本文提出了一种在不同小区中具有100%频率复用和不均匀业务负载不对称的TDMA(时分多址)蜂窝网络中最小化蜂窝间干扰和最大化频谱效率的新方法。采用了一种新的分布式介质访问控制(MAC)协议CSTDMA(载波感知时分多址)和改进的PRMA(分组保留多址)协议，并将其性能与当前最先进的MAC协议进行了比较。CSTDMA TDD采用改进的忙音广播/信道感知机制，而PRMA(分组保留多址)采用握手过程。结果表明，与最先进的方法相比，这种新方法的应用在系统容量和频谱效率方面有了显着提高，特别是与CSTDMA TDD方法相比，该方法总体上达到了最佳性能，提供了传统方法的3到4倍以上的容量和系统频谱效率
