An optimal power allocation scheme for cooperative CC-HARQ over ...

In this paper, the optimal power allocation (OPA) problem for Chase combining (CC)-based cooperative hybrid automatic repeat request (HARQ) protocol over block Rayleigh fading channels is addressed. With the constraints of the targeted outage probability and the maximum number of transmission rounds, we aim at determining the optimal power sequences of the source and the relay to minimize the average total power consumption. Towards solving the problem, the asymptotic outage probability and the
