Executive Summary

This paper presents the integration of power control and the Busy Burst (BB) technique for a TDD OFDMA (Time Division Duplex Orthogonal Frequency Division Multiple Access) system in an urban Manhattan grid type of environment. The objective is to combine power control with the BB protocol to develop a power efficient interference-avoidance technique. Previous work has demonstrated that the time multiplexed BB can be used to achieve interference aware medium access. It has also been demonstrated in other work that the implicit feedback mechanism of BB can be exploited to achieve Pareto optimal SINR-based (Signal-to-Interference-plus-Noise Ratio) power control.
