MULTIRECEIVER TIMING ADVANCE PROVISIONING

摘要

A method of operating a mobile station in a packet transfer mode includes receiving a distribution timing advance message on a control channel from a base station. The distribution timing advance message contains a plurality of mobile station identifiers and associated timing advance values. One of the mobile station identifiers is identified as corresponding to the mobile station. The timing advance value associated with the identified one of the mobile station identifiers is determined. The timing of an uplink transmission to the base station is then adjusted responsive to the timing advance value. Related mobile stations, methods of operating a base station subsystem to communicate timing advance values to a plurality of mobile stations, base station subsystems, and methods of operating a serving GPRS support node to control communication of timing advance values by a base station subsystem are also disclosed.

1. A method of operating a mobile station in a packet transfer mode, the method comprising:
monitoring a downlink packet associated control channel for arrival of a distribution timing advance message; receiving the distribution timing advance message on the downlink packet associated control channel from a base station, the distribution timing advance message comprising a plurality of mobile station identifiers and associated timing advance values; determining that a data packet is available in an uplink queue; identifying one of the plurality of mobile station identifiers received in the distribution timing advance message as corresponding to the mobile station; determining the timing advance value associated with the identified one of the plurality of mobile station identifiers; and transmitting the data packet in an uplink transmission to the base station based on adjusting a timing responsive to the timing advance value.
