%X In order to adapt to dynamical channel conditions and improve the transmission reliability, rate-adaptive cooperative relay transmission schemes are investigated under multi-relay selection in combination with incremental redundancy hybrid automatic repeat request and rate-compatible low density parity check code (RC-LDPC). With respect to random and specific distributions of relay nodes, two different multi-relay selection protocols are proposed with deriving the expressions for the outage probability and throughput performances of the system. Both numerical and simulation results show that introducing a cooperation between the relays can significantly improve the system performance in both outage probability and throughput under the considered specific relay distribution.
