This paper investigates the resource allocation problem for uplink multiple-access relay channels (MARC) with network coding. Firstly, the difference between traditional relay channels and MARC is presented, and then a joint optimization problem considering power allocation and relay selection is formulated to maximize the sum-rate under total power constraint. The optimal algorithm is proposed by...
Joint scheduling and resource allocation in uplink orthogonal frequency-division multiplexing (OFDM) systems is complicated and even becomes intractable with a large subcarrier and a large user number. This paper investigates the resource allocation for OFDM-based multiuser multiple-access relay channels (MARCs) with network coding. We formulate a joint optimization problem considering source-node...
