Abstract:
1. A method of receiving data transmissions in a wireless communication system, comprising: obtaining received symbols for at least one data transmission on at least one primary traffic channel from at least one primary terminal and at least one data transmission on at least one secondary traffic channel from at least one secondary terminal, wherein the at least one primary traffic channel is orthogonal to at least one other primary traffic channel and is not orthogonal to the at least one secondary traffic channel; processing the received symbols to obtain decoded data for each of the at least one primary terminal; estimating interference due to the at least one primary terminal; canceling the interference due to the at least one primary terminal from the received symbols to obtain interference-canceled symbols; and processing the interference-canceled symbols to obtain decoded data for each of the at least one secondary terminal.
