Embodiment Construction

[0017] In the current multi-user transmission of wireless LAN, transmission opportunity power saving and transmission opportunity truncation have their own advantages in terms of power saving and air interface resource saving, but the simultaneous use of the two will bring unfairness between sleeping users and non-sleeping users sex. If at most one of the two mechanisms is used in a transmission opportunity process, the two mechanisms cannot be combined to exert their respective advantages.

[0018] The embodiment of the present invention proposes a power saving mode management method, which is used to balance the joint use of the two mechanisms of power saving and transmission opportunity truncation.

[0019] refer to figure 1 , the method flow chart of the embodiment of the present invention, in a wireless local area network, each access point AP or terminal STA competes for the channel, the AP or STA that competes for the channel is the TXOP holder, and the one that does n...

Abstract

The invention embodiment provides a power saving mode management method used for balancing the competitive fairness of simultaneously-used two mechanisms of transmission opportunity (TXOP) power save and transmission opportunity truncation. The method comprises that whether a non-TXOP holder enters a sleep state is judged; after entering the sleep state, the non-TXOP holder enters a temporary waking state within at least one period of time before the transmission time corresponding to the TXOP is over; during the temporary waking state, if a state management frame is received by the non-TXOP holder, the non-TXOP holder enters a waking state; if the non-TXOP holder does not receive the state management frame, the non-TXOP holder continuously enters the sleep state; and wherein the non-TXOP holder maintains a receiving state during the temporary waking state.

Description

technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a method and device for saving power in a wireless local area network. Background technique [0002] The WLAN supports a mechanism called TXOP (transmission opportunity). When a station (STA, station) obtains a transmission opportunity, it can reserve a period of time, during which time one or more data frames can be continuously transmitted. A station that obtains a transmission opportunity is called a transmission opportunity holder (TXOP holder). The station at the receiving end of the data sent by the non-transmission opportunity holder will set a NAV (network allocation vector, network allocation vector) to ensure that it does not initiate competition within the time range reserved by the transmission opportunity holder. [0003] There is a transmission opportunity power save (TXOP PS, transmission opportunity power save) mechanism. The principle of...
