Abstract

The embodiment of the disclosure relates to a device power saving method, a communication device and a storage medium. The device power saving method includes that a first device is switched from a first capability mode to a second capability mode under at least one condition that a current TWT SP is confirmed to be terminated or ended, a service period is confirmed to be ended and no data is needed to be sent subsequently, and the starting time of the current TWT SP is confirmed to be expired to a first time. The first device is in the second capability mode, and before the negotiated TWT SP starts, the first device needs to switch from the second capability mode to the first capability mode to complete frame exchange in the TWT SP, further, when the TWT SP ends, the first device switches back to the second capability mode, and further, when the first device detects that TWT SP end/end information exists in the TWT SP, the first device switches back to the second capability mode. Based on the method, the embodiment of the disclosure is beneficial to reducing the energy consumption of equipment so as to improve the transmission efficiency.
