Abstract

A method for transmitting a communication signal (20) having a data rate over a plurality of spread spectrum traffic channels includes determining a first number of traffic channels required to transmit the communic ation signal at the data rate, and determining a second number of traffic channels (502) available for transmitting the communication si gnal (20). In response to a comparison of the first number of traffic to the second number of traffic channels, a first traffic channel (54 ) for transmitting a first portion of the communication signal (50, 51) and a second traffic channel (56) for transmitting a second portion of the communication signal (52, 53) are selected from the second number of traffic channels (502). The selection of the first traffic chan nel (54) is non deterministic of the selection of the second traffic channel (56).
