Description

Method and device for transmitting wake-up frame in wireless local area network

Technical Field

The present invention relates to the field of wireless network technologies, and in particular, to a method and an apparatus for transmitting wake-up frames in a wireless local area network.

Background

In a Wireless Fidelity (WiFi) network, a device wastes a considerable amount of energy in listening (idle waking) when no signal is received, and a related solution in the current legacy 802.11 protocol (802.11b/a/g/n/ac, etc.) focuses on optimizing a device sleep policy, except for optimizing the sleep policy, another technical approach to reduce the energy waste of the device idle waking is to use a low Power Wake-Up Receiver (L ow Power Wake Up Receiver, L P-WUR) (abbreviated as WUR herein), whose core idea is that a receiving end device (e.g., STA) adds a low Power Wake-Up Receiver (802.11main radio, 802.11 host transceiver module, WiFi host transceiver module) and adds a low Power Wake-Up Receiver (WUR) part, as shown in fig. 3, when the 802.11 host transceiver module goes into deep sleep, the low Power Wake-Up Receiver (e.g., STA) starts to operate if other devices (e.11 as shown in the figure) need to Wake Up with the AP and Wake Up the AP on the left side to Wake Up with the AP, and send a WUR Wake-Up frame to the AP after the STA goes into deep sleep, the AP starts to Wake Up with the AP, the AP to listen to the AP, and Wake Up the AP to listen to the STA, the AP to listen to the AP to Wake Up the host transceiver (802.11) to listen to the STA).

The technology adopts the WUR with low power consumption to replace an 802.11 host transceiver module to monitor a channel when the medium is idle (the energy consumption of the WUR monitoring/receiving state is expected to be about 0.1-1% of that of the 802.11 host transceiver module, namely less than 100uW), and the energy waste of equipment idle triggering can be effectively reduced.

802.11ax introduces Orthogonal Frequency Division Multiple Access (OFDMA) technology to achieve simultaneous point-to-multipoint transmission. The AP may transmit different data signals to multiple stations on multiple orthogonal subchannels simultaneously; in addition, a plurality of stations can transmit data signals to the AP through a plurality of orthogonal sub-channels at the same time.

However, how to design the structure and content of the wake-up frame is not proposed at present, so that the wake-up frame not only has a single-site wake-up function, but also has a multi-site simultaneous wake-up function, and the requirement of 11ax multi-site simultaneous transmission is met.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention can be applied to a Wireless local Area Network (W L AN), the standard adopted by the W L AN at present is IEEE (Institute of Electrical and electronics Engineers, Chinese) 802.11 series, the W L AN can comprise a plurality of basic service sets BSS, Network nodes in the basic service sets are stations, the stations comprise Access Point (AP) stations and Non-Access Point (Non-AP Station), and each basic service set can comprise AN AP and a plurality of Non-AP STAs related to the AP.

The AP is a bridge connected with a network and a Wireless network, and is mainly used for connecting various Wireless network clients together and then connecting the Wireless network to the Ethernet.

The STA may support AN 802.11ax format, and further optionally, the Station supports multiple W L AN formats such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a formats.

With the evolution of the wlan W L AN standard, the IEEE802.11 working Group is working on the development and formulation of 802.11 standard with low Power Wake-Up receivers (L ow Power Wake Up Receiver, L P-WUR) as the core technology to reduce Power consumption, the 802.11 standard has been formed with SG (Study Group) in IEEE 6 months in 2016, and TG (Task Group) in 2016, for short WUR.

In WiFi networks, a significant portion of the energy of the device is wasted listening (idlestoring) in the absence of a received signal, and the relevant solutions in the current legacy 802.11 protocols (802.11b/a/g/n/ac, etc.) focus on optimizing the device sleep strategy. As shown in the first time axis of fig. 2, when a device (e.g., a Station, STA, Station) does not transmit or receive messages (e.g., No data phase), considerable energy is consumed if the channel is continuously monitored (i.e., idle listening). Therefore, a Sleep Schedule (Sleep Schedule) is introduced in the second time axis of fig. 2, so that the STA can enter Deep Sleep (Deep Sleep) when there is no data transceiving, so as to reduce the energy consumption of continuous idle triggering. However, when the STA is in deep sleep, the AP cannot communicate with the STA, and only when the STA wakes up, transmission between the AP and the STA can be performed, which may cause a certain delay (latency). In order to avoid the high delay caused by the sleep mechanism, the STA usually wakes up from time to check whether data needs to be received or not according to a certain sleep strategy, which, however, reduces the sleep efficiency of the STA (waking up from time to time but without useful data needs to be transmitted or received, which consumes more energy than long-time sleep).

In addition to optimizing the sleep strategy, another technical approach to reduce the energy waste of device idle triggering is to use L P-WUR (abbreviated as WUR here) the core idea is that a receiving device (e.g. STA) adds a low power Wake-Up receiver (WUR) part in addition to a legacy 802.11 transceiver (802.11main radio, 802.11 host transceiver module, WiFi host transceiver module), as shown in fig. 3, when the 802.11 host transceiver module enters deep sleep, the low power WUR wakes Up to work, if other devices (e.g. AP on left side in the figure) need to communicate with a device with WUR and 802.11 host transceiver module (e.g. STA on right side in the figure), the AP first sends WUR Wake-Up frame (WUP, Wake Up Packet) to the WUR, when the WUR receives WUP correctly, the 802.11 host transceiver module wakes Up to sleep and then sends to the AP, the AP communicates with the 802.11 host transceiver module, when the 802.11 host and the AP enters sleep, the WUR starts to Wake Up to listen to the host.

In order to realize low power consumption, the WUR needs to have a simpler circuit structure, a simpler frame structure design (e.g., WUP), and the like, and to have low complexity. For example, a WUR circuit structure may only include energy detection (energy detect) and Radio Frequency (RF) parts, and thus cannot demodulate some complex modulation schemes. For this purpose, WUP may use On-Off Keying (OOK) modulation scheme or Frequency Shift Keying (FSK) scheme for simple implementation.

One possible WUP Frame structure is shown in fig. 9, which is preceded by L egacy 802.11preamble (legacy 802.11 preamble), which can be understood by other peripheral 802.11 devices (peripheral 802.11 devices that hear the preamble do not seize the channel for a period of time), which protects the subsequent part of the Wake-up Frame from interfering with legacy 802.11 devices, followed by payload (payload) part of the WUP, which is modulated with OOK, which only can be understood by WUR, which may include Wake-up preamble (Wake-up preamble, which identifies the WUP signal), MAC Header (including WUR ID, which distinguishes between different WURs), Frame body (Frame carriers, which may carry some other information), FCS (Frame Sequence, which ensures that the received data is the same as the data as it was sent), where WUR ID information may be part or the entire station identity, or the AP allocates the station r identity, or the received data as the data when it was sent, where WUR ID information may be part of the station identity, or the received station based on the MAC address of the received MAC Header, which may be distinguished between the station identity, or the received MAC address of the station ID, which may be based on the bandwidth of the legacy 802.11 MAC, or the MAC address of the transmission unit, which may be based on the basic MAC Header 20.

Fig. 10 shows another possible WUP frame structure, which includes an 802.11 legacy preamble, a wake-up preamble, a signaling field (for carrying some physical layer signaling, such as AP identification, WUR ID, modulation and coding indication, etc.), a MAC header, a frame body, and a frame check sequence.

802.11ax introduces OFDMA technology to achieve simultaneous point-to-multipoint transmission. The AP may transmit different data signals to multiple stations, i.e., downlink OFDMA, on multiple orthogonal subchannels simultaneously; in addition, a plurality of stations may transmit data signals to the AP through a plurality of orthogonal subchannels at the same time, that is, uplink OFDMA.

The embodiment of the invention mainly designs the structure and the content of the wake-up frame, so that the wake-up frame has the function of simultaneously waking up multiple sites, and meets the requirement of simultaneously transmitting the 802.11ax multiple sites. In addition, the wake-up frame still has a single-site wake-up function. Meanwhile, the wake-up frame further includes a receiving operation mode indication or a receiving operation mode request indication of the primary transceiver (such as the 802.11 primary transceiver module) to be woken up.

Referring to fig. 1, a system diagram of a typical deployment scenario of W L AN includes AN AP and 3 STAs associated with the AP, where the AP may communicate with STA1, STA2 and STA3, respectively, it should be noted that each STA may include a structure as shown in fig. 3, that is, both AN 802.11 host transceiver module and a L P-WUR module are included, and the L P-WUR module is configured to receive a wake-up frame sent by the AP and wake-up the 802.11 host transceiver module.

In this embodiment of the present invention, the AP sends a wake-up frame to at least one station STA associated with the AP, for example, sends a wake-up frame to at least one STA of STA1, STA2, and STA3 in fig. 1, where the wake-up frame is further used to indicate a receiving parameter, such as a receiving mode indication, a time indication of being woken up, of the at least one station that is woken up from the sleep state. When the main transceiver module of the STA is awakened, the STA can communicate with the AP. It should be noted that the present invention is not limited to the AP sending the wakeup frame to the non-AP STA, and the non-AP STA may also send the wakeup frame to the AP. The following embodiment takes the case where the AP sends a wakeup frame to the non-AP STA.

The following describes a method for transmitting a wake-up frame in a wireless lan according to an embodiment of the present invention with reference to fig. 4 to 12.

As an alternative embodiment, the wake-up frame may be used to wake up at least one station, or may be used to transmit BSS information parameters, which may be information parameters of BSS where a primary transceiver module of the station in a sleep state is located, or information parameters of BSS where L P-WUR of the station in the sleep state is located, the BSS information parameters including at least one of a timestamp, a channel number, a secondary channel difference, a frequency segment number, a bandwidth center frequency, an Enhanced Distributed Channel Access (EDCA) parameter, a beacon frame arrival time, a beacon frame interval, wherein the secondary channel difference is an indication of whether the secondary channel is higher or lower than the primary channel frequency, an embodiment is that the channel number is the primary channel number, the wideband center frequency includes wideband center frequency 1 and wideband center frequency 2. multiple wake-up receivers managed by the AP may operate on different channels, the narrowband wake-up frame may need to be transmitted on a BSS channel where the wake-up frame is located, and the wake-up frame used to transmit information parameters may be transmitted on multiple wake-up channels managed by the AP, such as a wireless wake-up frame, or a wireless wake-up frame, if the wake-up frame needs to be transmitted on multiple wake-up channel, such as a wireless wake-up frame.

In the embodiment of the present invention, frame type indication information is used to indicate a function of the wakeup frame, and if the frame type indication information is a first identifier, the wakeup frame is used to wake up at least one station, where the wakeup frame includes first indication information used to indicate the at least one station to be woken up and second indication information used to indicate a receiving parameter of the at least one station, and optionally, the wakeup frame may further include a BSS information parameter used to inform the wakened station of a BSS information parameter where a primary transceiver is located or a latest BSS information parameter. And if the frame type indication information is the second identifier, the wakeup frame is used for transmitting the BSS information parameter, and the wakeup frame comprises third indication information used for indicating the BSS information parameter.

When the AP sends a wakeup frame to the station, the wakeup frame further includes a maximum sleep time of the AP, which is used to help the unassociated station to determine whether to select to associate with the AP when receiving the wakeup frame. For example, the station usually sends emergency traffic, but if the maximum sleep time sent by the AP is greater than its tolerance, the station does not select the AP to associate with.

When the WUP frame is as shown in fig. 11c, only single site information is contained. The wake-up type included in the reception parameter may also comprise the above-mentioned frame type, i.e. replacing the first identity with the wake-up type in the reception parameter.

The wake-up frame may be a MAC frame or a Physical (PHY) frame, and the following two frame structures are described separately:

if the wake-up frame is a MAC frame, as shown in fig. 9, the structure of the wake-up frame may include an 802.11 legacy preamble, a wake-up preamble, a MAC header, a frame body, and a Frame Check Sequence (FCS), and fig. 10 shows another possible WUP frame structure, which includes an 802.11 legacy preamble, a wake-up preamble, a signaling field (for carrying some physical layer signaling, such as AP identification, WUR ID, modulation and coding indication, etc.), a MAC header, a frame body, and a frame check sequence. The 802.11 legacy preamble comprises a short training field, a long training field and a signaling field, and is used for preventing a legacy WIFI station from seizing a channel; a wake-up preamble to receive synchronization; the MAC header comprises the frame type indication information, a sending address, a receiving address and the like; the frame body carries specific control signaling, such as a receiving mode indication of a primary transceiver module of a station.

As will be described in detail below, the frame body of the MAC frame includes a common field and at least one single information field, and optionally, the common information may be carried by the common field, the at least one group information or the at least one station information may be carried by the at least one single information field of the frame body, and one single information field carries one group information or one single information field carries one station information. One piece of group information comprises one group identification or at least two station identifications and receiving parameters corresponding to the group identification or the at least two station identifications, and one piece of station information comprises one station identification and the receiving parameters corresponding to the station identification.

Further optionally, the MAC header includes the above-mentioned frame type indication information, and if the frame type indication information indicates that the awake frame is used to indicate BSS information parameters, a sending address in the MAC header is an address of an AP, a receiving address is a broadcast address, a frame body only includes a common field, and the common information includes information such as a timestamp, and optionally, the common information further includes length information.

If the frame type indication information indicates that the wake-up frame is used for waking up at least one station, the sending address in the MAC header is an AP address, the receiving address is a unicast address or a broadcast address, and the frame body contains a common field and a single information field. The common information carried by the common field includes a timestamp, frame structure type indication information and length information, and it should be noted that the frame structure type indication information is optional information.

Optionally, if the frame body is a single-site information structure, that is, the frame body includes one site information, the site information may not include the site identifier, because the receiving address may identify the site at this time.

If the wake-up frame is a physical frame, as shown in fig. 12, the wake-up frame includes a legacy preamble, a wake-up preamble, and a first signaling field SIG1 and a second signaling field SIG2, where the SIG1 field is similar to a common field in the MAC frame, and the SIG1 field carries common information, and further optionally, the SIG1 field further includes an identification of the AP, where the identification is a BSS identifier (BSSID), a partial BSSID, a BSS color, and the like of the AP. The second signaling field SIG2 is configured to carry the at least one group information or the at least one station information, and it should be noted that, when the SIG1 field and the SIG2 field are in a single-station information structure, the station information contains a station identifier.

After the AP generates the wakeup frame, it sends the wakeup frame, as shown in fig. 6, the AP sends the wakeup frame to a single station, and after receiving the wakeup frame, the station sends a PS poll frame to the AP to tell the AP that it is awake, and then the AP sends back an acknowledgement Ack or directly transmits data to the station. Alternatively, the AP may send the data frame directly to the station after the station wakes up, without waiting for the station to send the PS-Poll frame.

As shown in fig. 7, after receiving the wakeup frame, the AP sends a trigger/trigger frame to the multiple stations, where the trigger frame includes resource allocation scheduling information, and after receiving the trigger frame information, the multiple stations reply PS-Poll frames on different orthogonal subchannels through the OFMDA technique according to the resource scheduling information, so as to tell the AP that the master transceiver module of the station has been awakened.

As shown in fig. 8, after the AP sends the wakeup frame, after the master transceiver module of the station is awakened, the AP directly sends downlink OFDMA data to the plurality of stations, and then the plurality of stations reply the acknowledgement frame.

In addition, if the AP is equipped with a wake-up receiver for power saving purposes, the main transceiver of the AP will also sleep. The mentioned embodiments mentioned in the present invention are also applicable to the non-AP station waking up the AP, but the wake-up frame sent by the non-AP station does not include the BSS information parameter.
