Abstract :
Performance of a packetized data transmission in cellular CDMA is analyzed in presence of soft handoff and truncated power control. The combined effects of soft handoff parameters, truncated power control at physical layer and truncated ARQ at data link layer on throughput and delay performance of packet data under a prescribed delay constrain is studied. Truncated power control improves the performance by suspending transmissions of mobiles under deep fade along with soft handoff while further improvement is obtained by retransmission at link layer. A variable packet length scheme is studied where packet size is adjusted under different traffic and soft handoff conditions so as to maintain a prescribed level of packet loss associated with T-ARQ. Interactions between power truncation parameter and soft handoff parameters and their impact on data performance are investigated.
