Abstract:
A method of operating a mobile wireless code-division-multiple-access (CDMA) station to communicate data over a Common Packet Channel of a CDMA wireless network, the method comprising the steps of:receiving a first frame-timing signal from a first CDMA base station over a broadcast synchronization channel; receiving a second frame-timing signal from a second CDMA base station over a broadcast synchronization channel; transmitting a first access burst signal over a CDMA Common Packet Channel, the first access burst signal comprising a first preamble code in a time slot selected from a plurality of time slots having predefined relationships to the first frame timing signal; transmitting a second access burst signal over the CDMA Common Packet Channel, the second access burst signal comprising a second preamble code in a time slot selected from a plurality of time slots having predefined relationships to the second frame timing signal; receiving an acknowledgement signal from at least the first CDMA base station; selecting the first CDMA base station in response to the receiving of an acknowledgement signal; and transmitting a CDMA signal comprising packet data and control information over the CDMA Common Packet Channel to the first CDMA base station.
