Abstract :
The deployment of relay nodes is a viable solution to fulfil the demands of high throughput and ubiquitous access for future mobile radio communications. A relay can cooperate by transmitting either a repetition of the previously transmitted signal (repetition coding) or by sending new code bits which have not been transmitted before (incremental redundancy). In this paper, a general optimization method for the achievable code rates in an adaptive relay network with repetition coding and incremental redundancy is presented.
