Patent ID: 8050248

Claim:
A method for reducing retransmission delays in a wireless communication system with Automatic Repeat reQuest (ARQ) retransmission functionality, comprising: sending a protocol data unit (PDU) from a transmitting side towards a receiving side; monitoring, at the transmitting side, a low-level control signal from the receiving side, the low-level control signal being associated with a lower protocol layer than the layer of the ARQ retransmission functionality; and deciding whether a retransmission of the PDU is to take place based on information included in the low-level control signal; wherein the low-level control signal is a power control command and the included information comprises power control information; wherein the deciding step in turn comprises determining the number of power up commands from the receiving side for a predetermined period of time, whereby a high number of power up commands is an indication for retransmission.
