The problem of efficient communication over a quasi-static wireless fading channel is considered in this paper. The disadvantages of two well-known schemes, Single-Layer Transmission (SLT) and Multi-Layer Transmission (MLT), are pointed out. A new scheme named Aggressive Transmission with ARQ (AT-ARQ) is developed and optimized to provide better performance, at the expense of requiring ARQ feedback. Optimal power allocation among (re)transmissions is derived. A comprehensive performance comparison of the three schemes, under different performance metrics such as throughput, outage probability, and the combination of two, is reported via numerical simulations. Substantial performance improvement is observed with even 1-bit ARQ feedback in Rayleigh fading. 2008 IEEE.
