The next generation of mobile networks is expected to support real-time multimedia applications with different classes of traffic and diverse bandwidth requirements. The Orthogonal Frequency Division Multiple Access (OFDMA) system with time division duplex mode, employing asymmetric slot allocation between uplink and downlink, is a good solution for mixed realistic traffic. This paper investigates and discusses the effect of slot and subcarrier management strategy in an OFDMA system, in which each cell can adaptively control the resource allocation as per its prevailing traffic load. Considering traffic direction in home and neighbor cell, a total of four cases for interference pattern has been analyzed here.
