ABSTRACT:
A method and apparatus identifies (810) communication cells (500) in a simulcast radio communication system (100) comprising the cells (500) and a portable communication unit (PCU) (108). Identification bit .patterns (602, 604, 606) are assigned (802) to the cells (500) in a manner such that when transmissions of the identification bit patterns are received simultaneously from cells (500) adjacent to one another, thereby producing a received interference bit pattern (708), identities of the cells (500) received can be resolved to a subset of the cells (500) by analysis of the received interference bit pattern (708), wherein the subset is inclusive of the cells (500) received.
