A method (1300) for uplink resource allocation in dual transfer mode in a mobile station includes receiving (1310) an uplink state flag (USF) during a circuit switched downlink timeslot, decoding (1320) a number N of packet-switched timeslots available during a next uplink period, switching (1350) to transfer mode, and transmitting (1360) on N packet-switched timeslots in the next uplink period. By incorporating a USF into a circuit-switched timeslot, only one downlink timeslot is required (e.g., a combined circuit-switched and USF timeslot) as opposed to requiring two timeslots (e.g., a circuit-switched timeslot and a timeslot for the USF). If the number N is less than the maximum allowable packet-switched timeslots available during the next uplink period, the mobile station "listens" (1340) on the first free timeslot of the next downlink period (which immediately follows the circuit-switched timeslot of the next downlink period) before switching (1350) to transfer mode and transmitting (1360).
