Abstract
A wireless terminal adapted to function in a code division multiple access (CDMA) communications system is provided. The terminal includes a receiver adapted to receive frames having a slot structure in which there is a user identification channel and a shared channel, the shared channel having been transmitted using a plurality of Walsh codes, and containing content for either a plurality of voice users, a plurality of voice users and one high-rate data user, or only one high-rate data user. A slot of the shared channel contains content for a plurality of users which was transmitted in parallel using different Walsh code spaces for different users. The wireless terminal is adapted to decode the user identification channel to determine when a slot of the shared channel contains voice and/or high-rate data content for the wireless terminal.
