Method and system for real-time calibration and reporting of processing delay

摘要

The subject matter disclosed herein relates to a system and method for estimating transmit chain and receive chain processing delays by a first wireless device. In a particular implementation, a first signal may be wirelessly transmitted from a first wireless device and at least a portion of the first signal may be received by a receiver of the first wireless device during transmission of the first signal. A first transmit processing delay and a first receive processing delay associated with the first signal may be measured or determined based at least in part on the receipt of the at least a portion of the first signal during the transmission of the first signal.

1. A method, comprising:
forming a preamble and at least one data capsule at a first observed time measurement; wirelessly transmitting a first signal from a first wireless device at a second observed time measurement, wherein the first signal comprises the preamble and the at least one data capsule; receiving, by a receiver of the first wireless device at a third observed time measurement, at least a portion of the preamble of the first signal during transmission of the preamble of the first signal; measuring a combined first transmit chain and first receive chain delay of the first wireless device based at least in part on a calculated difference between the third and first observed time measurements during the transmission of the preamble of the first signal; and embedding a measurement of the combined first transmit chain and first receive chain delay of the first wireless device within the at least one data capsule of the first signal during the transmission of the preamble of the first signal, wherein the measurement is wirelessly transmitted within the at least one data capsule of the first signal.
