For the multiple-access relay channel with relay-source feedback, we derive an outer bound on the capacity region CMARC. We also derive an achievable rate region RFB which is in general larger than the capacity region without feedback. The presence of the feedback enables the sources to understand each other's messages, which in turn allows the sources to cooperate to resolve the residual uncertainty...
In this work we consider the achievable rates of a joint resource allocation for a three-node network where a half-duplex relay node enables bidirectional communication between nodes 1 and 2 and thereby adds an own multicast message to the communication. In the multiple access phase nodes 1 and 2 transmit their message to the relay node, which decodes the messages and forwards them in the succeeding...
