Abstract
In this study, a capacity inner bound for multiple-access relay channel (MARC) with side information (SI) non-causally known at one encoder was obtained, where transmitters cooperate with each other to transmit a common message with rate R 0 and individual messages with rates R 1 and R 2 . The achievable rate region was obtained by using Gel'fand-Pinsker (GP) method, superposition regular block Markov encoding/backward decoding, partial decode and forward (PDF) strategy. The derived inner bound includes a variety of previous works on the point to point, multiple-access (MAC), relay channel (RC) and MARC with and without SI at one encoder.
