A communication system provides wireless communication in a coverage area and includes a base station (100) and a mobile station (290). The base station (100) has a plurality of sectors (210, 220, 230, 240, 250, 260) where a corresponding plurality of pilot signals (212, 222, 232, 242, 252, 262) are transmitted. A sector (210) transmits a forward link signal (211) for communicating to the mobile station (290). The mobile station (290) transmits a reverse link signal (215) and a message signal including a list of a plurality of candidate sectors for a soft hand-off routine. A method and apparatus of determining the candidate list includes measuring reverse link signal (215) which are received at said plurality of sectors. Then, comparing reverse link signal level received at sector (210) to the reverse link signal levels received at all other sectors of said plurality of sectors (210, 220, 230, 240, 250, 260). Finally, the candidate list is determined according to a result of comparing the reverse link signal levels.
A method of determining a list of hand-off candidates in a communication system providing wireless communication in a coverage area, the communication system including a base station having a plurality of sectors, said base station transmitting a forward link signal adapted to communicate with a mobile station, said mobile station transmitting a reverse link signal and a message signal including said list of a plurality of hand-off candidate sectors, the method comprising the steps of:
A communication system providing wireless communication in a coverage area, comprising:
