Abstract:
1. A method comprising: partitioning a set of orthogonal codes into one or more subsets of orthogonal codes; partitioning a signal of data symbols into a plurality of packets, each packet being of a size comprising at least two data symbols; and encoding each of the plurality of packets with an orthogonal code from a one of the one or more subsets of orthogonal codes for transmission of the signal in a communication system, wherein the encoding includes mapping each of the packets to the orthogonal code of the one subset; and wherein either the set of orthogonal codes or the one subset of orthogonal codes is provided by a base station to a terminal, and wherein a number of orthogonal codes contained in the one subset of orthogonal codes is determined to facilitate a decrease in power required for the transmission while maintaining or increasing transmission capacity.
