Providing Internet services is very important in 3G
networks. TCP is the transport layer protocol used by
the majority of the applications on the Internet. We
studied the performance of TCP when utilizing link
layer retransmission (e.g. RLP in IS95 and IS2000)
and MAC layer retransmission in CDMA system.
There is not much work on how retransmissions in
these layers can work together and how the
performance of TCP with RLP and MAC
retransmissions would be. In this paper we propose an
analytical model for RLP performance when MAC
retransmission is presented in this architecture. We
also studied the performance of TCP based on RLP
and MAC with extensive simulation experiments. We
study in detail the interactions between different layers
and characterize the performance using delay
distributions and throughput. Our results show
significant improvement in TCP performance with
MAC layer retransmission. For example, for packet
loss rate of 0.1, the TCP packet delay is reduced by
20.94%, and throughput is increased by 39.57%.
