1. A method for signaling a request for uplink packet transmission resources at a mobile station in DTX transmission mode, comprising:
- detecting new data activity at the mobile station, the new data activity indicating that one or more uplink data packets are pending;
monitoring a downlink packet channel for a signal allocating to the mobile station one or more transmission periods in a corresponding uplink packet channel; and
transmitting a pre-determined dummy block over the uplink packet channel during the allocated one or more transmission periods, the pre-determined dummy block comprising an indication that the one or more uplink data packets are pending.

Abstract
A mobile station operating in extended uplink TBF mode detects renewed data activity. Upon receiving an allocation of an uplink transmission opportunity, the mobile station determines whether a data block corresponding to the renewed data activity is ready for transmission. If the data block is not ready for transmission, a dummy block, comprising an indication that one or more uplink data packets are pending, is sent to the base station at the allocated transmission opportunity. The base station responds by resuming continuous mode scheduling of the uplink for the mobile station.

10. A mobile station, comprising:
-
a transceiver section configured to transmit packet data to and receive packet data from a base station, and a processing unit configured to; detect new data activity at the mobile station, the new data activity indicating that one or more uplink data packets are pending; monitor a downlink packet channel for a signal allocating to the mobile station one or more transmission periods in a corresponding uplink packet channel; and transmit a pre-determined dummy packet over the uplink packet channel during the allocated one or more transmission periods, the dummy packet comprising an indication that the one or more uplink data packets are pending. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A base station comprising:
-
a base station transceiver configured to transmit packet data to and receive packet data from a mobile station; a scheduler for scheduling an uplink transmission by the mobile station during one or more uplink transmission periods while the mobile station is in a discontinuous transmission (DTX) mode; and a detection unit for determining whether a data block received from the mobile station during the scheduled one or more uplink transmission periods comprises a pre-determined dummy block indicating that uplink packet data from the mobile station is pending; wherein the scheduler is configured to begin allocating uplink transmission periods to the mobile station in a continuous transmission mode upon detection of the pre-determined dummy block by the detection unit. - View Dependent Claims (18, 19, 20)
