A method of data communication. The method includes transmitting a control message identifying missing data as lost by the transmitter prior to the expiration of a timer. The missing data may include at least one data packet such that the control message identifies the at least one missing data packet. The control message may include a field and/or an acknowledge sequence number for identifying the missing data packet. The control message also may include a packet data unit having a dummy payload and/or a zero payload. The control message communicates to the receiver that the transmitter has aborted the transmission and/or retransmission of the one or more missing data packets. The control message may be communicated to the receiver over the same data channel used for transmitting the data packets, or alternatively, a wholly different channel than the data channel.

The invention claimed is: 1. A method of data communication between at least one base station and at least one wireless unit, comprising: staffing a timer in the wireless unit in response to determining that at least one packet is missing; and transmitting a control message by the base station and received by the wireless unit identifying missing data as lost to the wireless unit prior to an expiration of the timer in the wireless unit. 2. The method of claim 1, wherein the missing data comprises at least one data packet, and the control message identifies the at least one missing data packet. 3. The method of claim 2, wherein the control message comprises a field and/or an acknowledge sequence number for identifying the missing data packet. 4. The method of claim 2, wherein the control message comprises a packet data unit having a dummy payload and/or a zero payload. 5. The method of claim 2, wherein the control message communicates an abortion in transmitting and/or retransmitting by a transmitter of the at least one missing data packet. 6. The method of claim 2, wherein a data channel is allocated for the transmission and/or retransmission of the at least one missing data packet, and the control message is transmitted over a different channel than the data channel. 7. A method of data communication between at least one base station and at least one wireless unit comprising: starting a timer in the wireless unit in response to determining that at least one packet is missing; and receiving a control message by the wireless unit and transmitted by the base station identifying missing data as lost to the wireless unit prior to an expiration of the timer in the wireless unit. 8. The method of claim 7, wherein the missing data comprises at least one data packet, and the control message identifies the at least one missing data packet. 9. The method of claim 8, wherein the control message comprises a field and/or an acknowledge sequence number for identifying the missing data packet. 10. The method of claim 8, wherein the control message comprises a packet data unit having a dummy payload and/or a zero payload. 11. The method of claim 8, wherein the control message communicates to a receiver an abortion in transmitting and/or retransmitting of the at least one missing data packet. 12. The method of claim 11, further comprising: transferring received data packets stored in a buffer for processing in response to receiving the control message. 13. The method of claim 11, further comprising: attempting recovery of the at least one missing data packet using a radio link control layer. 14. The method of claim 8, wherein a data channel is allocated for the reception of the at least one missing data packet, and the control message is transmitted over a different channel than the data channel. 15. A communications device comprising: a timer that is configured to start in response to determining that at least one packet is missing; a buffer for storing received data packets; and a processing unit for transferring the stored data packets from the buffer after the timer expires, for determining if at least one data packet is missing, and for deeming the at least one missing data packet as lost in response to receiving a control message before the timer expires. 16. The communications device of claim 15, wherein the control message comprises a field and/or an acknowledge sequence number for identifying the missing data packet. 17. The communications device of claim 15, wherein the control message comprises a packet data unit having a dummy payload and/or a zero payload. 18. The communications device of claim 15, wherein the control message communicates an abortion in transmitting, and/or retransmitting of the at least one missing data packet. 19. The communications devices of claim 15, further comprising: means for attempting recovery of the at least one missing data packet using a radio link control layer. 20. The communications device of claim 15, wherein a data channel is allocated for the reception of the at least one missing data packet, and the control message is transmitted over a different channel than the data channel.
