Abstract

The embodiment of the disclosure relates to the technical field of communication, and provides a power saving method, power saving equipment and a storage medium. The method comprises the steps that at a first moment before a first TWT SP negotiated by an AP and a first STA starts, when the AP communicates with a second STA in a first TXOP obtained by the second STA, the AP determines a capability mode after the first moment according to the ending time of the first TXOP and the starting time of the first TWT SP, wherein the AP is a responder of the first TXOP. The embodiment of the disclosure provides a mode for timely switching equipment capacity modes, and reduces equipment energy consumption.

Claims (10)

  1. A power saving method, the method comprising: at a first moment before a first TWT SP negotiated by an AP and a first STA starts, when the AP communicates with the second STA in a first TXOP obtained by a second STA, the AP determines a capability mode after the first moment according to the ending time of the first TXOP and the starting time of the first TWT SP; wherein the AP is a responder to the first TXOP.
  2. The method of claim 1, wherein the AP determining the capability mode after the first time based on an end time of the first TXOP and a start time of the first TWT SP comprises: When the end time of the first TXOP is not earlier than the start time of the first TWT SP, or when the end time of the first TXOP is earlier than the start time of the first TWT SP and a first time difference between the end time of the first TXOP and the start time of the first TWT SP is less than or equal to a first duration, the AP maintains a first capability mode after the first time; When the end time of the first TXOP is earlier than the start time of the first TWT SP and the first time period is longer than the first time period, the AP switches to a second capability mode after the end of the first TXOP and to the first capability mode before the start of the first TWT SP; The AP is in the first capability mode when communicating with the second STA, and the value of at least one working parameter of the AP in the second capability mode is smaller than the value in the first capability mode.
  3. The method of claim 2, wherein the first duration is a sum of a duration required for the AP to switch from the first capability mode to the second capability mode and a duration required for the AP to switch from the second capability mode to the first capability mode.
  4. The method according to claim 1, wherein the method further comprises: When the AP is in a second capability mode at the first moment, the AP is switched to a first capability mode before the first TWT SP starts; Wherein, the value of at least one working parameter of the AP in the second capability mode is smaller than the value in the first capability mode.
  5. The method of claim 2, wherein when the end time of the first TXOP is not earlier than the start time of the first TWT SP, the method further comprises: The AP transmits a first radio frame before the first TWT SP starts, the first radio frame being used to instruct the second STA to terminate the first TXOP.
  6. The method of any one of claims 2 to 5, wherein the AP is in the first capability mode within the first TWT SP; after the first TWT SP starts, the method further comprises at least one of: The AP participating in channel contention; The AP performs frame exchange with the first STA within the first TWT SP after successfully contending for the channel.
  7. The method of claim 6, wherein the method further comprises: After the first TWT SP ends, the AP switches from the first capability mode to the second capability mode.
  8. An AP, comprising: A processing module, configured to determine, at a first moment before a first TWT SP negotiated by an AP and a first STA starts, a capability mode of the AP after the first moment according to an end time of the first TXOP and a start time of the first TWT SP when the AP communicates with a second STA in a first TXOP obtained by the second STA; wherein the AP is a responder to the first TXOP.
  9. An AP, comprising: One or more processors; wherein the processor is configured to perform the method of any of claims 1-7.
  10. A storage medium storing instructions which, when executed on a communications device, cause the communications device to perform the method of any one of claims 1 to 7.
