A new frame-based packet reservation multiple access (F-PRMA) protocol under time-division duplexing is proposed for microcellular mobile communications, the simulation model of which is built. By extensive simulations, the performances of the multiple access protocol including packet dropping probability Pdrop, channel capacity M0.01 and system throughput ρ are analyzed under different speech service loads, and the effects of the system parameters and protocol variables on the efficiency of the protocol are examined throughout. The result of the study shows that the F-PRMA protocol is highly efficient under time-division duplexing (M0.01=36, multiple access gain η=1.6), and has almost the same performance as the original PRMA protocol under frequency-division duplexing
