Abstract:
1. A method for reducing a feedback delay of a packet data communication system, comprising: transmitting a first data packet from a source to a destination over a first slot; transmitting a second data packet from the source to the destination over a second slot, the second slot following the first slot and preceding a received acknowledgement signal; receiving the first data packet at the destination and decoding the first data packet; scheduling an acknowledgment signal for the first data packet over a first transmission slot and a re-transmission of the first data packet acknowledgment signal over a second slot; receiving the second data packet at the destination and decoding the second data packet; scheduling an acknowledgement signal for the second data packet over the second slot, wherein the acknowledgment signal for the second data packet overwrites the scheduled re-transmission of the first data packet acknowledgment signal; and transmitting the acknowledgment for the first data packet over the first transmission slot and transmitting the acknowledgment for the second data packet over the second transmission slot.
