Claim 20:
21. A non-transitory computer-readable medium configured to store instructions that, when executed by a processor, cause an electronic device to:
observe transmitted and received higher layer data packets in a TWT operation during an observation time period;
determine, based on physical (PHY) layer transmission and reception data rates during the observation time period, effective higher layer transmission and reception data rates;
estimate an initial data transceiving time of the data packets based on the effective higher layer transmission and reception data rates and total lengths of the transmitted and received data packets;
adjust the initial data transceiving time to obtain a higher layer data transceiving time based on an estimated network congestion level, an estimated required re-transmission rate, and a total amount of TWT overhead during the observation time period;
determine a minimum duty cycle for the TWT operation as a ratio of the higher layer data transceiving time to the observation time period;
jointly determine, based on the minimum duty cycle, a new TWT service period and a new TWT interval for the TWT operation under joint constraints that a latency introduced by the TWT operation does not exceed a maximum latency amount and that the new TWT interval is as large as possible;
determine whether a ratio of the new TWT service period to the new TWT interval exceeds a predetermined first threshold;
based on the ratio exceeding the first threshold, use the new TWT service period and the new TWT interval to negotiate an adjusted TWT service period and TWT interval for the TWT operation; and
based on the ratio not exceeding the first threshold, stop the TWT operation.
