Abstract
A method in a monitoring station configured for communication with a wireless device is described. The method includes determining a round trip time, RTT, that corresponds to a first packet transmitted to the wireless device; receiving a second packet from the wireless device; determining the second packet from the wireless device has been received without error based at least in part on an error-detecting field; and receiving a subsequent packet from the wireless device. The method further includes determining that the subsequent packet received is a second packet retransmission; determining a preamble receipt time of the subsequent packet; determining a delay value based in part on the RTT of the first packet, the length field of the subsequent packet, and data rate field of the subsequent packet. The first acknowledgement packet is transmitted timed at the delay value after the preamble receipt time of the subsequent packet.
