Selective repeat hybrid ARQ is not used in terrestrial systems. However, selective repeat hybrid ARQ can largely improve the data throughput with the same memory size as N-channel stop and wait ARQ in GEO satellite environment. Therefore, we research the application of selective repeat hybrid ARQ. In this paper, we analyze the receiver buffer overflow phenomenon, which is the one of most important problem of the application of selective repeat hybrid ARQ. From this analysis, we can give the insight about the proper receiver buffer size. In addition, we propose the method of explicit buffer overflow notification for preventing consecutive packet errors of selective repeat hybrid ARQ type II.
