Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for implementing a site sleep.
Background
A Basic Service Set (BSS) is a Basic component of a Wireless Local Area Network (WLAN), in a BSS, Stations (STA) having a certain association form a BSS, in a BSS, a Station that manages the BSS in a dedicated manner is called an Access Point (AP), and the AP is associated with a Station in the BSS where the AP is located, for example, in a BSS, the AP may be a base Station and the STA may be a mobile terminal.
In the existing wlan standard, the AP and the STA can obtain Transmission time (i.e., Transmission Opportunity) through channel contention under a hybrid coordination Function (hybrid coordination Function) mechanism. Once the TXOP is obtained by either the AP or the STA, the channel can be continuously used without re-contending for the channel for the duration of the TXOP. In a TXOP, not all STAs receive data frames, so a Very High Throughput (VHT) TXOP power save mode (VHT TXOPpower save mode) is introduced, which is used to enter a sleep (Doze) state when a STA finds that no data frame is sent to itself, thereby saving power consumption during the TXOP.
In the prior art, for an STA (generally, a non-AP VHTSTA) supporting TXOP power saving, if a current message frame sent by an AP includes a sleep permission instruction (i.e., STAs in the BSS are permitted to enter a sleep state during a TXOP), the STA may enter the sleep state until the current TXOP is ended when any one of the following conditions 1 to 5 is satisfied:
(1) by receiving the GROUP identification (GROUP _ ID) parameter in the parameter vector (RXVECTOR), the STA finds itself not to be a member of the GROUP;
(2) STA finds that PARTIAL association identifier (PARTIAL _ AID) in RXVECTOR is not equal to 0 and does not match with self PARTIAL association identifier (match);
(3) the STA finds that a PARTIAL association identifier (PARTIAL _ AID) in RXVECTOR matches with its own PARTIAL association identifier, but a correctly received Receiver Address (RA) in a Medium Access Control (MAC) header of the current frame does not match with its own MAC address.
(4) The STA finds itself to be a member of the packet as indicated by the GROUP _ ID parameter in RXVECTOR, but the Number of space-Time Streams (NUM _ STS for short) in RXVECTOR it receives is 0.
(5) The STA sends an acknowledgement (acknowledgement) frame in response to receiving a message frame sent by the AP containing no more data command (i.e., more data field equals 0), the message frame requesting the STA to send a response frame and the response frame is an acknowledgement frame
However, in the prior art method, when a STA receives a message frame addressed to the STA and the frame contains a sleep enable instruction and no more data instruction, but the frame does not require a response frame or the required response frame is not an acknowledgement frame, the STA cannot enter the sleep state.

Example two
Another method for implementing station sleep is provided in the embodiments of the present invention, as shown in fig. 3,
310. the transmitting station AP obtains the transmission time TXOP.
311. The AP transmits a message frame including a sleep enable instruction and no more data instruction to the target station STA0 in the obtained TXOP, the message frame does not require a response frame, and a Receiver Address (RA) Address of the message frame matches a Medium Access Control (MAC) Address of the STA 0.
The target station is an expected receiving station of the message frame sent by the sending station.
In all embodiments of the present invention, the matching between the receiving end address of the message frame and the MAC address of the destination station includes various situations, which may be that the receiving end address of the message frame is the same as the MAC address of the destination station, the receiving end address of the message frame is the same as the MAC address of the destination station after changing according to a predetermined rule, or the MAC address of the destination station is the same as the receiving end address of the message frame after changing according to a predetermined rule, and so on.
In addition, the type of the message frame is not limited in the embodiment of the present invention, and the message frame may be any frame, for example, any data frame, management frame, control frame, and the like.
Specifically, a very high throughput information field in an AP physical layer header carries a parameter that does NOT allow transmission Opportunity Power saving (Transmit Opportunity Power Save NOT ALLOWED, abbreviated as TXOP _ PS _ NOT _ ALLOWED), and a bit of this parameter is used to indicate whether Power saving is ALLOWED or NOT, and then TXOP _ PS _ NOT _ ALLOWED is set to 0 to indicate that a sleep instruction is ALLOWED; TXOP _ PS _ NOT _ ALLOWED is set to 1, indicating that the sleep instruction is NOT ALLOWED; no more data instruction by setting more data field to 0;
the message frame does not require a response frame, specifically including whether the acknowledgement policy of the message frame is No acknowledgement (No ACK) or Block acknowledgement (Block ACK), or the frame type of the message frame does not require a response frame. Specifically, when the acknowledgement policy of the message frame is no acknowledgement, the target station does not send a response frame, that is, does not send any information to the sending station; when the acknowledgement strategy of the message frame is block acknowledgement, the acknowledgement mode does not require immediate feedback of the BA, and the BA is fed back after the target station receives the BA request frame.
In the embodiment of the present invention, when a message frame does not require a response frame, except for a manner that an acknowledgement policy of the message frame is no acknowledgement or block acknowledgement or a frame type of the message frame does not require the response frame, a sending station does not require a target station to send the response frame, for example, when the TXOP acquired by the sending station does not have enough time to allow the target station to send the response frame in the current TXOP, or when the TXOP acquired by the sending station is acquired by reverse grant through some other receiving station (the station is a reverse initiator), and the target station is not a reverse initiator, the target station does not send the response frame to the sending station.
312. The receiving station STA receives the message frame transmitted by the transmitting station. In all embodiments of the present invention, a receiving station refers to any receiving station.
313. The STA determines whether itself is a target station of the message frame (in this embodiment, the target station of the message frame is STA 0). Specifically, when the MAC address of the STA matches the address of the receiving end of the message frame, the STA is the target station of the message frame; when the MAC address of the STA is not matched with the RA address of the message frame, the STA is not the target station of the message frame.
The STA further determines whether the message frame includes a sleep enable instruction, whether the message frame includes a no more data instruction, and whether the message frame requires a response frame.
In the embodiment of the present invention, the receiving station is not limited to determine whether the receiving station itself is a target station, determine whether the message frame includes a sleep permission instruction, determine whether the message frame includes a no more data instruction, and determine whether the message frame requires a response frame.
314. And when the STA judges that the STA is the target site of the message frame, the message frame comprises a sleep allowing instruction and no more data instruction, and the message frame does not require a response frame, the STA enters a sleep state after receiving the message frame.
The embodiment of the invention provides a method for realizing station sleep, when a message frame sent to a target station by a sending station comprises a sleep permission instruction and no more data instruction, and the message frame does not require a response frame, and a receiving station can enter a sleep state after receiving the message frame under the condition that the receiving station is the target station, thereby saving power consumption.

411. The AP transmits a message frame including a sleep enable instruction and a no more data instruction to the target station STA0 in the obtained TXOP, the message frame requires a response frame, and a destination address of the message frame matches the MAC address of the STA 0.
Specifically, a very high throughput information field in an AP physical layer header carries a parameter that does NOT allow transmission Opportunity Power saving (Transmit Opportunity Power Save NOT ALLOWED, abbreviated as TXOP _ PS _ NOT _ ALLOWED), and a bit of this parameter is used to indicate whether Power saving is ALLOWED or NOT, and then TXOP _ PS _ NOT _ ALLOWED is set to 0 to indicate that a sleep instruction is ALLOWED; TXOP _ PS _ NOT _ ALLOWED is set to 1, indicating that the sleep instruction is NOT ALLOWED; no more data instructions are indicated by setting the more data field to 0.
The response frame required by the message frame may be an acknowledgement frame or a non-acknowledgement frame.
The response frame in this embodiment is a non-acknowledgement frame, which is any frame except an acknowledgement frame, and may include any data frame, management frame, or control frame.
412. The STA receives the message frame sent by the sending station.
413. The STA determines whether itself is a target station of the message frame (in this embodiment, the target station of the message frame is STA 0). Specifically, when the MAC address of the STA matches the address of the receiving end of the message frame, the STA is the target station of the message frame; when the MAC address of the STA is not matched with the RA address of the message frame, the STA is not the target station of the message frame.
The STA also determines whether the message frame includes a sleep allowed instruction and no more data instruction, and whether the message frame requires a response frame.
In the embodiment of the present invention, the receiving station is not limited to determine whether the receiving station itself is a target station, determine whether the message frame includes a sleep permission instruction, determine whether the message frame includes a no more data instruction, and determine whether the message frame requires a response frame.
414. When the STA judges that the STA is the target station STA0 of the message frame, and the message frame includes a sleep permission instruction and no more data instruction, and the message frame requires a response frame, the STA enters a sleep state after sending the response frame to the AP; wherein the response frame is a non-acknowledgement frame.
