Resource Allocation for Soft Handoff in Wireless Packet CDMA Systems
Packet-oriented wireless networks provide additional flexibility in the allocation of resources to mobiles during soft handoff periods. In this paper, two different scheduling disciplines are developed for transmission of packets in the forward link of a cellular CDMA. Both algorithms are based on a double round robin approach. One is based on site selection diversity while the other uses the combining diversity technique. The algorithms provide a fair access to the radio resources among users located in the handoff and non-handoff areas. We present performance results, compare the two techniques and quantify the benefits of using site selection diversity.
