Abstract:

This paper investigates the performance of relay networks in the presence of hybrid automatic repeat request (ARQ) feedback and adaptive power allocation. The throughput and the outage probability of different hybrid ARQ protocols are studied for independent and spatially correlated fading channels. The results are obtained for the cases where there is a sum power constraint on the source and the relay or when each of the source and the relay are power-limited individually. With adaptive power allocation, the results demonstrate the efficiency of relay–ARQ techniques under different conditions.

I. Introduction

Relay-assisted communication is one of the promising techniques that has been proposed for wireless networks. The main idea of a relay network is to improve the data transmission efficiency by implementation of intermediate relay nodes that support the data transmission from a source to a destination. The relay networks have been adopted in the Third-Generation Partnership Project Long-Term Evolution Advanced standardization [1] and are expected to be one of the core technologies for the next-generation cellular systems.
