1. A multiple access communication method in a mobile station, comprising the steps of:
- monitoring a downlink slot to detect a USF (Uplink Status Flag); and
transmitting on an uplink slot corresponding to the USF, wherein (i) if shifted USF operation is not used then a first downlink slot is monitored to detect a USF corresponding to a first uplink slot and (ii) if the shifted USF operation is used then a second downlink slot is monitored to detect the USF corresponding to the first uplink slot and a USF corresponding to a second uplink slot.

Abstract
A method for control of packet data transmissions in a TDMA wireless network to provide for additional choices in the allocation of communication channels. The fixed relationship in the timing of the downlink allocation signalling and subsequent uplink transmission is altered for certain classes of mobile station to avoid physical constraints. Examples of variations in USF signalling in GPRS are given.
