Joint power and frame allocation for TDD-based cooperative relaying system

Abstract

Cooperative relaying transmission is proved to be a feasible method for QoS guaranteed and dead-spot coverage. In this paper, the power and frame allocation schemes are proposed for TDD-based cooperative relaying system. Based on the related work on adaptive frame allocation (FA), the optimal power allocation (PA) is deduced for compress-and-forward (CF) relaying, and the optimal PA and FA schemes are also addressed for decode-and-forward (DF) relaying transmission. Moreover, the joint power and frame allocation (JPFA) schemes are proposed based on mesh grid searching algorithms for both CF and DF system. Simulation results show that the effect of FA is stronger than that of PA method, while the proposed JPFA outperforms the other schemes through the joint optimization by utilizing the power and the time resource efficiently.
