Interference Management and Handoff Techniques in Ultra Mobile Broadband Communication Systems

Abstract

Wireless communications of the next generation rely on large bandwidths and orthogonal frequency division multiple access (OFDMA) techniques to achieve high data rates. In a OFDMA-based wireless wide area network (WWAN), e.g., a cellular network, interference management and handoff are keys to the system performance, such as capacity, coverage, and stability. This paper introduces novel interference management schemes for use in a OFDMA cellular communication system that include dynamic fractional frequency reuse scheme and other cell interference based power control for interference control and avoidance and handoff schemes that employs disjoint links and beacons in a OFDMA cellular communication system.
