In this paper, the waiting time analysis for an OFDMA wireless cellular system with finite buffering and Adaptive Modulation and Coding (AMC) is addressed. When AMC is considered, several concentric regions within cells serving users with different data rates are differentiated. Phase type (PHT) distribution functions are used to model the conditional cumulative distribution function of the waiting...
Achieving the targeted data rates for next generation wireless communication systems requires using frequency reuse ratio 1 in these systems, but this in turn results in significant intercell interference observed especially by the users near cell edges. Cooperation between the base stations plays an important role in reducing the intercell interference. In this paper, we consider the problem of cooperative...
This paper introduces a beacon coding and signaling technique and its application to handoff in OFDMA cellular communication networks. Beacon signaling provides an efficient alternative to the conventional tune-away approach for inter-carrier/frequency handoff. The proposed handoff technique transmits beacon pilots in other carrier frequencies in the network allowing for easy and early detection of...
