Abstract :
Multiple access schemes in which the transmitting nodes are allowed to cooperate have the potential to provide higher quality of service than conventional schemes. In the class of half-duplex pairwise cooperative multiple access schemes in which channel state information is available at the transmitters, the allocation of transmission power and communication resources plays a key role in the realization of these quality of service gains. In this paper we propose a half-duplex cooperative multiple access scheme and develop an efficient algorithm for the joint allocation of power and the communication resources. We demonstrate that the new scheme can attain a significantly larger fraction of the achievable rate region for the full duplex case than an existing scheme that does not employ resource allocation.
