Abstract

This paper presents a new analytical framework for the analysis of inter-cellular timeslot allocation over TDMA (time division multiple access) based air-interfaces using TDD (time division duplexing). The analysis is used to evaluate the delay- throughput performance of an adaptive decentralized inter- cell interference mitigation technique that exploits the inherent channel reciprocity of TDD. The main principle is that receivers upon successful transmission of a packet transmit a busy burst on a succeeding minislot. Potential transmitters in neighboring cells sense the minislot prior to signal transmission. With this mechanism, inter-cell interference to the existing link is avoided. The performance of this MAC (medium access control) protocol is compared against blind timeslot allocation. The new MAC protocol is shown to facilitate network self-organization, offering superior delay and throughput compared to the state of the art, with modest overhead and complexity requirements.
