Description

Wake-up method, receiving device and sender device

This application claims priority to Chinese Patent Application No. 201610891863.1, entitled "Wake-up Method, Receiving Device, and Transmitter Device" on October 12, 2016, the entire contents of which are incorporated herein by reference. In the application.

Technical field

The present application relates to the field of wireless communications, and more particularly to a wake-up method, a sink device, and a sink device.

Background technique

With the development of mobile communication technologies, mobile applications are increasingly diversified and device functions are continuously enriched. Reducing the energy consumption of equipment has become one of the important technical goals of wireless networks. The existing Wireless Fidelity (Wi-Fi) technology uses the Target Wake Time (TWT) mechanism to schedule stations (Stations, STAs) to wake up from the energy-saving state at different time points, and reduce the STAs that use the energy-saving mode. Need to wake up.

For example, in the 802.11ah standard, a receiving device (for example, a STA) and a transmitting device (for example, an access point (AP)) establish a TWT protocol (Agreements) through a TWT request message and a TWT response message, and jointly negotiate STAs. Wake up at TWT to communicate with the AP. For example, 802.11ax supports multi-user Uplink/Downlink (MU UL/DL) transmission. In a TWT service period (SP), multiple users can simultaneously communicate. In 802.11ax, there are two TWT mechanisms: Individual TWT (Individual TWT) and Broadcast TWT (Broadcast TWT). The TWT mechanism is similar to the TWT mechanism in the 802.11ah standard. A single or multiple users establishing the TWT protocol wake up waiting for communication at the negotiated TWT time point, but all the waking users are not necessarily scheduled in the TWT, and no STAs are scheduled. Wake up wasting energy.

In the broadcast TWT, a broadcast TWT request may be initiated by a STA (scheduled STA) that can be scheduled by the TWT, and the AP will schedule multiple STAs to communicate in the broadcast TWT, and all the energy-saving STAs (Power Saves, PS STAs) will be in the agreed target. The beacon transmission time (TBTT) wakes up to receive a beacon frame, and the beacon frame can carry information related to the broadcast TWT. The station that receives the beacon frame wakes up at the broadcast TWT time. Waiting for scheduling, but only some STAs communicate in the TWT Service Period (TWT Service Period), and other wake-up STAs waste power. The STAs scheduled in the broadcast TWT may not have the need to communicate to transmit data, and these STAs are awake in the broadcast TWT to be scheduled not only wasting energy but also wasting channel resources.

How to properly schedule the wake-up and sleep modes of the STA is an urgent problem to be solved.

Summary of the invention

The embodiment of the present invention provides a wake-up method, a receiving end device, and a sending end device, which can reasonably schedule the wake-up and sleep states of the receiving end device.

In a first aspect, a wake-up method is provided, the method being performed by a receiving device, the receiving device comprising a master transceiver and a wake-up receiver WUR, the method comprising: the receiving device acquiring a target wake-up time TWT; before the TWT, the receiving device receiving a wake-up packet WUP through the WUR; the receiving device And maintaining, according to the target receiving device information carried by the WUP, the main transceiver to sleep in the TWT or waking up the main transceiver through the WUR at the TWT.

The embodiment of the present application determines whether the primary transceiver of the receiving device needs to be woken up according to the WUP before the TWT, so that the primary transceiver of the receiving terminal device that does not need to wake up keeps sleeping in the TWT, and the receiving terminal device needs to wake up through the primary transceiver. Wake up to receive the schedule, which enables reasonable scheduling of sleep and wake-up of the receiving device.

With the existing TWT mechanism, the TWT scheduled receiving device wakes up, but does not need to wake up the device, for example, the device that has no data transmission during this time period wakes up to increase power consumption. With the method of the embodiment of the present application, before the TWT, it is determined by the WUP which devices need to wake up, and which devices do not need to wake up, so that all scheduled receiving devices are avoided, and power consumption can be reduced.

In one embodiment of the present application, the wake-up receiver may change from the sleep mode to the wake-up mode when receiving the wake-up packet, so as to avoid energy loss caused by the wake-up receiver staying in the wake-up mode.

detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments.

FIG. 1 is a schematic diagram of an application scenario of a communication system to which an embodiment of the present application is applicable. The Wireless Local Area Network (WLAN) shown in FIG. 1 includes a transmitting end device (such as the AP shown in FIG. 1) and a receiving end device (such as the STA shown in FIG. 1). The AP is responsible for two-way communication with a plurality of STAs, for example, the AP shown in FIG. 1 transmits downlink data to STAs (for example, STA1 and STA2 in FIG. 1), or the AP receives uplink data from STAs (for example, STA3 in FIG. 1). . It should be understood that the number of APs and STAs shown in FIG. 1 is merely illustrative, and any number of APs and STAs may be included in the WLAN.

The technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, and a wideband code division multiple access. (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication system.

In the embodiment of the present application, the AP may provide an access service for the station, and the AP may be an access point in the WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, or a base station in WCDMA. (NodeB), which may also be an evolved Node B (eNB or e-NodeB) in LTE. This application does not limit this.

In the embodiment of the present application, the station may be various stations (Stations, STAs) supporting the WLAN communication protocol, or may be terminals in the GSM or CDMA or WCDMA (Terminal), user equipment (User Equipment), and mobile stations (Mobile). Station, MS), mobile terminal, etc., the station can communicate with one or more core networks via a Radio Access Network (RAN), for example, the station can be a mobile phone (or called " Cellular "telephone", smart home, computer with mobile terminal, etc., for example, the station can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that exchanges voice and/or data with the wireless access network. .

In the embodiment of the present application, an example is shown in which the receiving device is an AP and the sending device is a STA.

2 is a schematic diagram of the steps of an existing wake-up method. The single TWT of FIG. 2 is exemplified by taking the sending device as the AP and the receiving device as the STA.

Step 1. The STA sends a TWT request message to the AP.

Step 2: The AP sends a TWT response message to the STA.

The AP receives the TWT request message sent by the STA, and sends a TWT response message to the STA according to the TWT request message. The TWT protocol is established between the receiving device and the transmitting device, and the value of the TWT can be determined when the TWT protocol is established.

In step 3, a trigger (Trigger) frame is sent to the STA at the TWTAP.

The STA wakes up in TWT and waits for the scheduling of the trigger frame to prepare for uplink transmission.

Step 4: After receiving the trigger frame, the STA feeds back the uplink frame to the AP.

After receiving the trigger frame, the STA may respond to the AP with an uplink frame, such as a Power Save Poll frame or a Data frame, if it is scheduled in the current trigger frame. If it is not scheduled in the current trigger frame, the Cascaded Field value of the trigger frame is 1, that is, there are other trigger frames after the trigger frame, otherwise the sleep mode can be performed.

In step 5, the AP sends an acknowledgement frame to the STA.

After receiving the energy-saving polling frame or data frame sent by the STA, the AP may send a Multi-user Block Acknowledge (M-BA) frame to the STA to confirm the STA.

Alternatively, when the AP sends a downlink data transmission (DL Data Transmission) frame to the STA, the STA may also be triggered to confirm using a Block Acknowledge (BA) frame.

Figure 2 above shows the flow diagram when the STA needs to wake up or say that the STA has a polling frame or a data frame needs to be transmitted. If the STA scheduled by the AP does not need to wake up, for example, there is no polling frame or data frame between the STA and the AP, and the STA wakes up wasting energy.

3 is a schematic diagram of the steps of another conventional wake-up method. The broadcast TWT of FIG. 3 is exemplified by taking the transmitting device as an AP and the receiving device as an STA, including STA1 and STA2.

Step 1: STA1 sends a TWT request message to the AP, and the AP receives the TWT request message.

Step 2: The AP sends a TWT response message to STA1, and STA1 receives the TWT response message.

The AP receives the TWT request message sent by STA1, and sends a TWT response message to STA1 according to the TWT request message. The TWT protocol is established between the receiving device and the transmitting device. When the TWT protocol is established, the STA1 negotiates with the AP to wake up the TBTT and the interval to be listened to. The listening interval is the TWT scheduling STA1 needs to maintain. The time interval in which the wake-up state receives the beacon frame. The TWT field of the TWT element (Element, IE) is set to the first TBTT by negotiation.

Step 3: The AP sends a Beacon frame to the STA (including STA1 and STA2), and the STA receives the beacon frame sent by the AP.

After successfully negotiating the broadcast TWT, the TWT scheduling STA can enter the sleep mode. All TWT scheduling STAs wake up at the first TBTT time point of the negotiation to receive the Beacon frame sent by the AP. The beacon frame carries the TWT element to set the broadcast TWT parameter. For example, the beacon frame carries the transmission trigger frame. The target wake-up time TWT1 and the target wake-up time TWT2 of the Multi-User Physical Layer Protocol Data Unit (MU PPDU) are transmitted.

Step 4: The AP sends a trigger frame to the STA, and the STA receives the trigger frame sent by the AP.

After the STA receives the beacon frame, the STA may enter the sleep mode again, and wake up to wait for the communication at the TWT1 time point indicated in the beacon frame. For example, at time TWT1, the AP sends a trigger frame to the STA, and the STA wakes up to receive the AP. Trigger frame. This step is similar to step 3 of FIG. 2 and will not be described in detail herein.

Step 5: After receiving the trigger frame, the STA feeds back the uplink frame to the AP, and the AP receives the uplink frame.

This step is similar to step 4 of FIG. 2 and will not be described in detail herein. For example, the upstream frame may be the polling frame shown in FIG.

In step 6, the AP sends an acknowledgement (M-BA) frame to the STA, and the STA receives the acknowledgement frame.

The AP sends an acknowledgement frame to the STA to acknowledge receipt of the poll frame sent by the STA.

In step 7, the AP sends a MU PPDU to the STA, and the STA receives the MU PPDU.

At the time TWT2 indicated in the beacon frame, the AP sends a MU PPDU to the STA, and the STA wakes up to wait for communication, that is, the STA wakes up to receive the MU PPDU sent by the AP.

In step 8, the STA sends an acknowledgement (BA) frame to the AP, and the AP receives the acknowledgement frame.

The STA sends an acknowledgement frame to the AP, indicating that the MU PPDU sent by the AP has been received.

Figure 3 above shows the flow diagram when the STA needs to wake up, or the STA has a polling frame or a data frame to transmit. If the STA scheduled by the AP does not need to wake up, for example, there is no polling frame or data frame between the STA and the AP, and the STA wakes up wasting energy. Also, the STAs scheduled in the broadcast TWT may not have the need to communicate to transmit data, and these STAs are awake in the broadcast TWT to be scheduled not only wasting energy but also wasting channel resources.

The existing wake-up method is given above in conjunction with FIG. 2 and FIG. 3. The wake-up method of the present application is specifically given below in conjunction with the embodiment of the present application. In the implementation of the present application, the receiving end device may be an STA, the sending end device is an AP, or the receiving end device may be an AP, and the sending end device is an STA. The specific example of the present application is described by taking the receiving device as the STA and the sending device as the AP.

4 is a schematic interaction diagram of a wake-up method according to an embodiment of the present application. The communication system of FIG. 4 includes a transmitting device and a receiving device, and the receiving device is composed of a wake-up receiver and a main transceiver.

101. The sender device acquires a TWT.

102. The receiving end device acquires the TWT through the primary transceiver.

Step 101 and step 102: The sending end device and the receiving end device acquire the TWT, and the receiving end device and the sending end device negotiate the value of the TWT when establishing the TWT protocol. The TWT value may be sent by the sending end device directly to the receiving end device, or may be determined by the receiving end device to send the TWT value to the sending end device, and the receiving end device and the transmitting end device may negotiate to determine the value of the TWT.

For example, in a separate TWT mechanism, the value of the TWT can be determined in the following manner: the STA sends a TWT request message to the AP, and the AP receives the TWT request message sent by the STA, and sends a TWT response message to the STA according to the TWT request message, and the receiving end device The TWT protocol is established between the device and the sender device, and the value of the TWT is determined when the TWT protocol is established.

For example, in the broadcast TWT mechanism, the value of the TWT can be determined in the following manner: the STA can wake up to receive the beacon frame in the agreed TBTT, and the beacon frame can carry the value of the broadcast TWT, and the value of the TWT can be multiple. For example, the value of the TWT may include TWT1 that transmits the trigger frame and TWT2 that sends the MU PPDU.

In an embodiment of the present application, the receiving end device and the transmitting end device may negotiate to determine whether the WUP is required to assist the wake-up mechanism of the primary transceiver of the receiving end device. The receiving end device may obtain indication information, where the indication information is used to indicate that the receiving end device adopts a mechanism for determining whether the TWT primary transceiver remains dormant according to the WUP.

For example, the indication information may be included in the TWT request message, may also be included in the TWT response message, or may be determined by the receiving end device and the sending end device.

As another example, the indication message is carried in other messages during the establishment of the TWT protocol. For another example, the receiving end device and the transmitting end device separately transmit or negotiate the indication message by using signaling.

In an embodiment of the present application, when the receiving end device and the transmitting end device wake up the main transceiver of the receiving end device by using the wakeup process of FIG. 4, it is required to establish that the receiving end device supports determining whether the TWT main transceiver remains dormant according to the WUP. mechanism. In an embodiment of the present application, before the step 103, the receiving end device may send a data frame to the sending end device, where the data frame is used to indicate that the receiving end device supports determining, according to the WUP, whether the TWT primary transceiver remains dormant. . This indication can be indicated by multiplexing existing fields of the data frame, or by efficient aggregation. The field redesigns the field for indication.

In another embodiment of the present application, the receiving end device may send a data frame to the sending end device, where the data frame may be used to indicate that the receiving end device supports an existing wake-up mechanism that wakes up the main transceiver at the TWT wake-up receiver.

For example, the MAC frame header of the data frame carries an operation mode indication OMI field, and the OMI field includes a bit for indicating that the receiving end device supports determining whether the TWT primary transceiver remains dormant according to the WUP. Specifically, the OMI in the 802.11ax allows the STA to dynamically adjust the appropriate number of receiving antennas and the channel bandwidth to receive subsequent PPDU frames. The OMI can be identified in the MAC frame header of the data frame, etc., so that the management layer can be used to improve the MAC layer. effectiveness. Preferably, there are 2 bits of reserved bits in the OMI, and the reserved bits in the OMI can be used to further indicate whether the TWT mechanism is supported, or the reserved bits in the OMI can be used to further indicate whether the TWT mechanism combined with the WUP is supported. Specifically, the schematic diagram of the OMI is as shown in FIG. 10. When the STA has a transmission requirement at a current time or a certain period of time, the TWT scheduling field is set to 1, indicating that the STA supports the TWT and the WUP determination mechanism at this time, and can be Scheduling; when the STA does not have a transmission request at the current or the next time, the TWT scheduling field is set to 0, indicating that the STA does not support the judgment mechanism of the TWT combined with the WUP at this time, and cannot be scheduled.

In addition, in an embodiment of the present application, the OMI field carried by the MAC frame header of the data frame may also be used to indicate that the receiving end device supports determining, according to the WUP, whether the TWT needs to wake up the bit of the primary transceiver.

For another example, the data frame includes a high-efficiency aggregation field, and the high-efficiency aggregation field includes a TWT scheduling support indication field, and the TWT scheduling support indication field is used to indicate that the receiving end device supports determining whether the TWT primary transceiver remains dormant according to the WUP. Specifically, the TWT scheduling support indication information is carried in the High Efficient Aggregated Control (HE-A-control) field of the High Throughput Control (HT-control) field. The HE-A-control field can carry different control information through different control identifiers (control IDs), as shown in FIG. A new control identifier may be used in the control field to indicate that the HE-A-control carries information about the TWT scheduling support indication. The specific method is as shown in FIG. 12, when the STA has a transmission requirement at a current time or a certain period of time, the TWT scheduling support indication field is set to 1, indicating that the STA supports the TWT to be scheduled at this time, and can be broadcasted by the TWT. When the STA does not have a transmission request at the current or the next time, the TWT scheduling support indication field is set to 0, indicating that the STA does not support the judgment mechanism of the TWT combined with the WUP at this time, and cannot be scheduled.

Step 102 is an optional step. Optionally, the sending end device may also acquire the wake-up packet WUP before step 103.

103. Before the TWT, the sending end device sends the wake-up packet WUP to the receiving end device, and the receiving end device receives the WUP by waking up the receiver.

The embodiment of the present application can determine whether the primary transceiver of the receiving end device needs to be woken up by using the WUP, for example, determining whether the main transceiver needs to be woken up according to the information of the target receiving end device carried by the WUP. In an embodiment of the present application, the target receiving device information carried by the WUP may be an ID of the receiving device. When the receiving device is divided into different groups, the target receiving device information may also be a group ID, or may be Other information carried by the WUP to determine if the primary transceiver is to be woken up.

For example, if the information carried by the WUP includes the ID of STA1 or the group ID of STA1, it indicates that the STA1 primary transceiver needs to be woken up. On the other hand, if the information carried by the WUP does not include the ID of the STA2 or the group ID of the STA2, it means that the STA2 main transceiver does not need to be woken up.

When the receiving device has communication requirements, it needs to wake up the primary transceiver of the receiving device. For example, the transmitting device has a downlink data frame, a control frame, a trigger frame, and the like, and needs to be transmitted to the receiving device, or the receiving device has an uplink data frame. When a polling frame or the like needs to be transmitted to the transmitting device, it is necessary to wake up the primary transceiver of the receiving device. When the receiving device does not have communication requirements, the primary transceiver of the receiving device can be kept to sleep, reducing energy loss.

In the embodiment of the present application, the TWT is combined with the WUP. Before the TWT, it is determined by the WUP whether the primary transceiver of the receiving device needs to be woken up, and the TWT mechanism determines the wake-up time as the value of the TWT. In this way, the WUP does not need to wake up the receiving device to stay asleep in the TWT, and the receiving device that needs to wake up wakes up in the TWT, so as to avoid energy loss caused by unnecessary wakeup.

In one embodiment of the present application, the time at which the transmitting device sends the WUP and the time at which the receiving device receives the WUP through the WUR may be a time point, or may be a time period, such as [T1, T2]. Defining a time interval can overcome the WUR drift in time due to inaccuracy in WUR time, and can also satisfy the situation where the AP sends multiple WUPs. For the point in time, T1 = T2. Preferably, [T1, T2] is the target time. If the WUP is not received within the target time period, it may be considered that the WUP is not received, or may wait for a preset duration, or the expiration time may be additionally defined. If you wait for the preset duration, or if you have not received the WUP after reaching the expiration time, you can think that the WUP has not been received. When the WUP is not received, the wake-up receiver does not need to wake up the main transceiver, and the main transceiver can maintain the sleep mode.

In an embodiment of the present application, the time for sending the WUP may be indicated by the AP in the process of negotiating the TWT protocol, or may be indicated in the beacon frame, and may also be specified as a fixed value by the standard. This is not a limitation.

Regardless of the manner in which the WUP is sent, the receiving device and the transmitting device can obtain the time for transmitting the WUP, so that the receiving device turns on the WUR at this time to prepare to receive the WUP. Since the STA can acquire the time for sending the WUP, the WUR can sleep before the time period, further saving the power consumption of the WUR. In this way, STAs that would otherwise wake up in the TWT but are not scheduled during the TWT service period can remain in sleep mode, reducing power consumption.

In an embodiment of the present application, the time for transmitting the WUP may be an absolute value of time or a relative value of time. Preferably, the start and end times T1 and T2 of the time period in which the WUP is transmitted are relative values with respect to the TWT.

104. At the TWT, the receiving device wakes up the main transceiver according to the wake-up packet by the wake-up receiver or keeps the main transceiver from sleeping.

For example, if the information carried by the WUP includes the ID of STA1, the wake-up receiver of STA1 wakes up the main transceiver of STA1 at the TWT. On the other hand, if the information carried by the WUP does not include the ID of STA2, the wake-up receiver of STA2 keeps STA2's main transceiver dormant at the TWT. In this way, STA2, which does not need to wake up, can avoid unnecessary wake-up and can reduce energy loss.

The wake-up method of the present application will be described in detail below with reference to specific embodiments. In the specific embodiment of the present application, the transmitting end device in FIG. 4 is an AP, the receiving end device is an STA, and the STA is composed of a main circuit and a wake-up receiver.

FIG. 5 is a schematic diagram of a wake-up method according to an embodiment of the present application. The communication system of the wake-up method shown in FIG. 5 may include an AP and an STA, wherein the STA is composed of a primary transceiver MR and a wake-up receiver WUR.

Step 1: The STA sends a TWT request message to the AP through the MR, and the AP receives the TWT request message.

The TWT request message is transmitted between the AP and the MR. At this time, the WUR can be in the sleep mode, and the MR is the wake mode. formula.

Step 2: The AP sends a TWT response message to the STA, and the STA receives the TWT response message through the MR.

The TWT request message is transmitted between the AP and the MR. At this time, the WUR can be in the sleep mode and the MR is the awake mode.

The TWT protocol can be established between the receiving device and the transmitting device through the TWT request message and the TWT response message, and the value of the TWT is determined. The MR of the STA can wake up to receive data frames, control frames, management frames, and the like transmitted by the AP in the TWT.

Step 3: Before the TWT, the AP sends a WUP to the STA, and the STA receives the WUP through the WUR.

The transmission time of WUP is [T1, T2], and T1 and T2 can be the same or different.

The WUP is transmitted between the AP and the WUR before the TWT. During this time, the WUR wakes up to receive the WUP, that is, the WUR is in the awake mode, and the MR can be in the sleep mode.

When the WUP includes the STA's ID, the STA's wake-up receiver needs to wake up the main transceiver at the TWT.

Step 4: In the TWT, the AP sends a Trigger (TF) frame to the STA, and the STA receives the trigger frame sent by the AP through the MR.

The trigger frame is transmitted between the AP and the MR. At this time, the MR is in the awake mode, and the transmission time of the trigger frame is TWT. When the TWT is determined and the WUP indicates that the WUR wakes up the MR, the MR wakes up in the TWT. WUR can stay dormant during this time.

Step 5: The STA sends a Power Save Poll (PS-Poll) or Data (Data) frame to the AP through the MR, and the AP receives the energy-saving poll frame or the data frame.

When transmitting an energy-saving polling frame or data frame, the WUR can remain dormant and the MR is in wake-up mode.

Step 6. The AP sends an M-BA frame to the STA, and the STA receives the M-BA frame through the MR.

When transmitting M-BA frames, WUR can remain dormant and MR is in wake-up mode.

Step 7: The STA sends an uplink data transmission frame to the AP through the MR, and the AP receives the uplink data transmission frame.

When transmitting an upstream data transmission frame, the WUR can remain dormant and the MR is in wake-up mode.

The time period during which the WUR and MR can be in sleep mode is indicated in FIG. In the embodiment of the present application, through the combination of the WUP and the TWT mechanism, the AP and the STA's main transceiver have a transmission requirement to wake up, and can maintain the sleep mode when there is no transmission requirement, thereby reducing unnecessary wake-up Energy loss. WUR wakes up when receiving WUP, and can remain in sleep mode at other times. This ensures that WUR wakes up to receive wake-up packets at a more accurate time, while other times can be in sleep mode, further reducing energy consumption.

FIG. 6 is a schematic diagram of a wake-up method according to another embodiment of the present application. The communication system of the wake-up method shown in FIG. 6 may include an AP and an STA, wherein the STA is composed of a primary transceiver MR and a wake-up receiver WUR. The STA of FIG. 6 differs from the schematic diagram of the wake-up method of FIG. 5 in that the wake-up method of FIG. 6 does not require wake-up. For example, the WUP of FIG. 6 does not include the identification information of the STA, indicating that the TWT does not need to wake up the main transceiver, and the main transceiver maintains the sleep mode in the TWT, so as to avoid unnecessary energy caused by the wakeup of the STA without transmission requirements. loss. Other processes and corresponding modes are the same as those shown in FIG. 5, and will not be described in detail herein.

FIG. 7 is a schematic diagram of a wake-up method according to still another embodiment of the present application. The communication system of the wake-up method shown in FIG. 7 may include an AP and three STAs, and the three STAs are STA1, STA2, and STA3, respectively, wherein the STA is composed of a corresponding primary transceiver MR and wake-up receiver WUR. The information carried by WUP2 is used to indicate that STA1 and STA2 do not need to be woken up, and STA3 needs to be woken up. In Fig. 7, ON indicates the wake-up mode, and OFF indicates the sleep mode.

Optionally, the WUR of STA3 needs to be in the awake mode when transmitting WUP2, and can maintain the sleep mode or the awake mode when transmitting WUP1. The AP and the STA can negotiate the target wake-up time of different WUPs when establishing the TWT protocol, so that the STA3 does not detect its own identifier at the target wake-up time of the WUP1, and the WUR of the STA3 can be kept in the sleep mode, and then wake up when the WUP2 is transmitted. It is also possible to maintain the wake-up mode until WUP2 is received (as shown in Figure 7). Similarly, the WUR of STA1 and STA2 can be in wake-up mode or in sleep mode when transmitting WUP2.

The above FIG. 5 to FIG. 7 show a single TWT mechanism, that is, the AP in FIG. 5 to FIG. 7 is used to schedule a single STA. The broadcast TWT mechanism will be described below with reference to FIG. 8 to FIG. 12, that is, the AP can simultaneously schedule multiple STA transmission requirements.

FIG. 8 is a schematic diagram of a wake-up method according to still another embodiment of the present application. The communication system of the awake method shown in FIG. 8 may include an AP and three STAs, and the three STAs are STA1, STA2, and STA3, respectively, wherein the STA is composed of a corresponding primary transceiver MR and a wakeup receiver WUR, that is, three STAs. Corresponding to WUR1, MR1, WUR2, MR2, WUR3, MR3. STA1 and STA2 are sites that need to be woken up, and STA3 is a site that does not need to be woken up.

Step 1: STA1 sends a TWT request message to the AP through MR1, and the AP receives the TWT request message.

The TWT request message is transmitted between the AP and the MR1. At this time, the WUR1 may be in the sleep mode, the MR1 is the awake mode, and the STA2 and the STA3 are not involved in the transmission of the TWT request message, and the STA2 and the STA3 may remain in the sleep mode.

Step 2: The AP sends a TWT response message to STA1, and STA1 receives the TWT response message through the MR.

The TWT response message is transmitted between the AP and MR1. At this time, WUR1 can be in sleep mode and MR1 is in wake mode. STA2 and STA3 are not involved in the transmission of the TWT response message, and STA2 and STA3 can remain in the sleep mode during this period.

The AP and the STA may establish a TWT protocol through the TWT request message and the TWT response message to determine the value of the TWT. The MR of the STA can wake up to receive data frames, control frames, management frames, and the like transmitted by the AP in the TWT. The TWT may be one or more. For example, the TWT in FIG. 8 may include TWT1 and TWT2, where TWT1 may be a time to transmit a Trigger frame, and TWT2 may be a time to transmit a DL MU PPDU.

During the establishment of the TWT protocol, the STA can negotiate the transmission time TBTT and the listening time of the target beacon frame with the AP.

Step 3: The AP sends a Beacon frame to the STA, and the three STAs receive the beacon frame through the corresponding MRs.

The beacon frame is transmitted between the AP and the MR, and MR1, MR2, and MR3 are in the awake mode during the time period in which the beacon frame is transmitted, and WUR1, WUR2, and WUR3 may be in the sleep mode during the period in which the beacon frame is transmitted.

The beacon frame may carry a TWT IE, and the TWT IE may include an NDP Paging field field carrying a T1 value and a T2 value. For example, the NDP Paging field is 4 bytes, the first two bytes carry the T1 value, and the last two bytes carry the value of T2 in microseconds. The time range of T1, T2 can be (0, 65 536) microseconds.

Step 4: Before TWT1, the AP sends WUP1 to the STA, and the STA receives WUP1 through the WUR.

The transmission time of WUR is [T1, T2], and T1 and T2 can be the same or different. T1 and T2 may be relative values of TWT1 or may be relative values of TBTT.

WUP1 is transmitted between the AP and the WUR before the TWT, during which WUR1, WUR2, and WUR3 wake up to receive WUP1, that is, the WUR is in the awake mode, and MR1, MR2, and MR3 can be in the sleep mode.

Step 5: In the TWT, the AP sends a Trigger (TF) frame to the STA, and the STA receives the trigger frame sent by the AP through the MR.

The trigger frame is transmitted between the AP and the MR. At this time, MR1, MR2, and MR3 are in the awake mode, and the transmission time of the trigger frame is the TWT1 time. When the TWT1 is determined and the WUP indicates that the WUR wakes up the MR, the MR1 and the MR2 wake up in the TWT. Since STA3 has no transmission requirements, for example, WUP1 does not include the identifier of STA3, and MR3 remains dormant. WUR1, WUR2, and WUR3 can remain dormant during this time.

Step 6: The STA sends an uplink energy-saving polling frame UL PS-Poll or an uplink data frame to the AP through the MR, and the AP receives the uplink energy-saving polling frame or the uplink data frame.

When transmitting the uplink energy-saving polling frame or data frame, WUR1, WUR2, and WUR3 can remain dormant, and MR1 and MR2 are in the awake mode. Since STA3 has no transmission requirement, MR3 remains dormant.

In step 7, the AP sends an M-BA frame to the STA, and the STA receives the M-BA frame through the MR.

When transmitting M-BA frames, WUR1, WUR2, and WUR3 can remain dormant, MR1, and MR2 are in wake-up mode, and MR3 remains dormant.

Step 8. Before TWT2, the AP sends WUP2 to the STA, and the STA receives WUP2 through the WUR.

The transmission time of WUR is [T3, T4], and T3 and T4 can be the same or different. T3 and T4 may be relative values of TWT2 or may be relative values of TBTT.

WUP2 is transmitted between the AP and WUR before TWT2, during which WUR1, WUR2 and WUR3 wake up to receive WUP2, ie WUR is in wake-up mode, while MR1, MR2 and MR3 can be in sleep mode.

Step 9. At the time of TWT2, the STA sends an uplink data transmission frame to the AP through the MR, and the AP receives the uplink data transmission frame.

When transmitting the uplink data transmission frame, WUR1, WUR2 and WUR3 can remain dormant, MR1 and MR2 are in wake-up mode, STA3 has no transmission requirement, and MR3 remains dormant.

Step 10: The STA that receives the uplink multi-user PPDU sends an acknowledgement (BA) frame to the AP, indicating that the transmitted uplink multi-user PPDU frame has been received.

When transmitting BA frames, WUR1, WUR2, and WUR3 can remain dormant, MR1 and MR2 are in wake-up mode, STA3 does not transmit data, and MR3 remains dormant.

The time period in which three WURs and three MRs can be in sleep mode is indicated in FIG. In the embodiment of the present application, through the combination of the WUP and the TWT mechanism, the STA's main transceiver wakes up when there is a transmission demand, and can maintain the sleep mode when there is no transmission requirement, which can reduce the energy loss caused by unnecessary wake-up. . WUR wakes up when receiving WUP, and can remain in sleep mode at other times. This ensures that WUR wakes up to receive wake-up packets at a more accurate time, while other times can be in sleep mode, further reducing energy consumption.

Optionally, the AP and the STA may agree to send the WUP1 before the TBTT, where the WUP1 is used to indicate that the STA that needs to wake up the beacon frame needs to be awake at the TBTT time, as shown in FIG. 9.

The MAC frame in 802.11ax includes OMI. The OMI includes a Receiver Number of Spatial Stream (NSS) field, a Receiver Channel Width field, a TWT Scheduling Field, and a To Be Decided (TBD) field. The OMI allows the STA to dynamically adjust the number of suitable receiving antennas and the channel bandwidth to receive subsequent PPDU frames. The OMI can be identified in the MAC header of the data frame, etc., and the transmission efficiency of the MAC layer can be improved relative to the management frame alone. There are 2 reserved bits in the OMI, and a reserved bit in the OMI can be used to further indicate whether TWT scheduling is supported.

If the STA has data requirements at the current or next time, the TWT scheduling domain is set to 1, indicating that the STA supports TWT scheduling at this time, and can be broadcasted by the TWT. If the STA does not have data demand at the current or next time, the TWT scheduling field is set to 0, indicating that the STA does not support TWT scheduling at this time, and cannot be scheduled by the broadcast TWT.
