ABSTRACT:
A user equipment transmits a signature in a selected one of a plurality of time slots of a common packet channel. The common packet channel is defined by a predetermined set of codes and has a plurality of access opportunities. Each access opportunity is defined by a time slot of the plurality of time slots and a signature. An identifier of a selected code of the predetermined set of codes is identified. The selected code is selected from a currently unused code, if available, based on a code association with the access opportunity defined by the selected signature and selected one time slot. The user equipment communicates using the one selected code.
