Abstract
A device-to-device (D2D) communication mode underlaying cellular network in a single-cell environment is introduced. A practical method based on link adaptation with automatic repeat request (ARQ) is presented. Link adaptation technique, which combines adaptive modulation and coding (AMC) with truncated ARQ, can maximize the cellular UEs' data rate under prescribed delay and performance constraints. The proposed method can maximize the total transmission rate when an outage probability is determined. Numerical results show that with proper power control, the interference between the two links can be coordinated to increase the sum rate without overwhelming the cellular service.
