A New Achievable Rate Region for the Relay Channel with Forwarding Own Messages

Bin Duo, Zhenyong Wang and Xuemai Gu

Abstract:
The traditional relay channel as an important component of wireless networks has received considerable attention in recent years. In order to fully utilizing the wireless resources, a novel relay channel model, the Relay Channel with Forwarding Own Messages (RC-FOM), is proposed. In such study, the relay has an own message for the destination in addition to the traditional communication from the source to the destination with the help of the relay. Upper bounds as well as an achievable rate region are derived based on the Decode-and-Forward (DF) strategy for the discrete memoryless RC-FOM. For the Additive White Gaussian Noise (AWGN) channels, the corresponding achievable rate region is proved theoretically and validated numerically. This new achievable scheme can be flexibly reduced to the classic relay channel and thus seen as a generalization of the relay channel.
