Description

一种无线局域网中唤醒帧的传输方法及装置Method and device for transmitting wake-up frame in wireless local area network 技术领域Technical field
本发明实施例涉及无线网络技术领域,尤其涉及一种无线局域网中唤醒帧的传输方法及装置。The embodiments of the present invention relate to the field of wireless network technologies, and in particular, to a method and an apparatus for transmitting a wake-up frame in a wireless local area network.
背景技术Background technique
在无线保真(Wireless Fidelity,WiFi)网络中,设备相当一部分能量浪费在无接收信号时的监听(idle listening),当前传统802.11协议(802.11 b/a/g/n/ac等)中相关解决方案集中在优化设备休眠策略。除了优化休眠策略外,减少设备idle listening能量浪费的另一条技术途径是使用低功耗唤醒接收机(Low Power Wake Up Receiver,LP-WUR)(这里简称为WUR)。其核心思想是接收端设备(如STA)除包含传统802.11收发端(802.11 main radio,802.11主收发模块,WiFi主收发模块)外,新增低功耗唤醒接收机(WUR)部分,如图3所示,当802.11主收发模块进入深度休眠后,低功耗的WUR苏醒开始工作。如果其他设备(如图中左侧的AP)需要与带有WUR和802.11主收发模块的设备(如图中右侧的STA)通信,AP首先给WUR发送WUR唤醒帧(Wake Up Packet,WUP),WUR正确收到发给自己的WUP后唤醒STA的802.11主收发模块然后自己转入休眠,AP则与苏醒的802.11主收发模块进行通信。当802.11主收发模块与AP通信完成后会进入休眠,同时WUR苏醒又开始侦听是否有发送给自己的WUP,以便唤醒802.11主收发模块。In a Wireless Fidelity (WiFi) network, a considerable part of the energy of the device is wasted in the idle listening mode. The current traditional 802.11 protocol (802.11 b/a/g/n/ac, etc.) is related to the solution. The solution focuses on optimizing the device sleep strategy. In addition to optimizing the sleep strategy, another technical way to reduce the waste of device idle listening energy is to use Low Power Wake Up Receiver (LP-WUR) (herein referred to as WUR). The core idea is that the receiving device (such as STA) includes a new low-power wake-up receiver (WUR) part, in addition to the traditional 802.11 main radio (802.11 main radio, 802.11 main transceiver module, WiFi main transceiver module), as shown in Figure 3. As shown, when the 802.11 master transceiver module enters deep sleep, the low-power WUR wake-up begins to work. If other devices (the AP on the left side of the figure) need to communicate with the device with the WUR and 802.11 primary transceiver module (the STA on the right side in the figure), the AP first sends a WUR Wake Up Packet (WUP) to the WUR. After the WUR correctly receives the WUP sent to itself, it wakes up the STA's 802.11 master transceiver module and then goes to sleep itself. The AP communicates with the awake 802.11 master transceiver module. When the 802.11 main transceiver module communicates with the AP, it will go to sleep. At the same time, the WUR wakes up and starts to listen to whether there is a WUP sent to itself to wake up the 802.11 main transceiver module.
该技术采用了低功耗的WUR代替802.11主收发模块在媒介空闲时侦听信道(这里期望WUR侦听/接收状态的能耗约为802.11主收发模块的0.1~1%,即小于100uW),能够有效降低设备idle listening时能量的浪费。The technology uses a low-power WUR instead of the 802.11 main transceiver module to listen to the channel when the medium is idle (the power consumption of the WUR listening/receiving state is expected to be about 0.1 to 1% of the 802.11 main transceiver module, that is, less than 100 uW). Can effectively reduce the waste of energy when the device idle listening.
802.11ax引入正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)技术,实现点对多点进行同时传输。AP可以同时在多个正交子信道上传输不同数据信号给多个站点;另外,多个站点也可以同时通过多个正交子信道传输数据信号给AP。802.11ax introduces Orthogonal Frequency Division Multiple Access (OFDMA) technology to achieve point-to-multipoint simultaneous transmission. The AP can simultaneously transmit different data signals to multiple sites on multiple orthogonal subchannels. In addition, multiple sites can simultaneously transmit data signals to the AP through multiple orthogonal subchannels.
然而目前并未提出如何对唤醒帧结构及内容进行设计,使其不但具有单站点唤醒功能,还具备多站点同时唤醒功能,满足11ax多站点同时传输的需求。However, it is not proposed how to design the wake-up frame structure and content, so that it not only has a single-site wake-up function, but also has a multi-site simultaneous wake-up function to meet the needs of 11ax multi-site simultaneous transmission.

具体实施方式detailed description
下面结合本发明实施例中的附图对本发明实施例进行描述。The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.
本发明实施例可以应用于无线局域网(Wireless Local Area Network,WLAN),目前WLAN采用的标准为IEEE(英文:Institute of Electrical and Electronics Engineers,中文:电气和电子工程师协会)802.11系列。WLAN可以包括多个基本服务集BSS,基本服务集中的网络节点为站点,站点包括接入点类的站点(Access Point,AP)和非接入点类的站点(英文:None Access Point Station,简称:Non-AP STA),每个基本服务集可以包含一个AP和多个关联于该AP的Non-AP STA。The embodiment of the present invention can be applied to a Wireless Local Area Network (WLAN). Currently, the standard adopted by the WLAN is the IEEE (Institute of Electrical and Electronics Engineers) 802.11 series. The WLAN may include a plurality of basic service sets BSS, and the network nodes in the basic service set are sites, and the stations include access point-type sites (Access Point, AP) and non-access point-type sites (English: None Access Point Station, referred to as : Non-AP STA), each basic service set may contain one AP and multiple Non-AP STAs associated with the AP.
接入点类站点,也称之为无线访问接入点或热点等。AP是移动用户进入有线网络的接入点,主要部署于家庭、大楼内部以及园区内部,典型覆盖半径为几十米至上百米,当然,也可以部署于户外。AP相当于一个连接有线网和无线网的桥梁,其主要作用是将各个无线网络客户端连接到一起,然后将无线网络接入以太网。具体地,AP可以是带有WiFi(英文:Wireless Fidelity,中文:无线保真)芯片的终端设备或者网络设备。可选地,AP可以为支持802.11ax制式的设备,进一步可选地,该AP可以为支持802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式的设备。Access point class sites, also known as wireless access points or hotspots. The AP is an access point for mobile users to enter the wired network. It is mainly deployed in the home, inside the building, and inside the campus. The typical coverage radius is tens of meters to hundreds of meters. Of course, it can also be deployed outdoors. An AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect the wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP may be a terminal device or a network device with a WiFi (English: Wireless Fidelity) chip. Optionally, the AP may be a device supporting the 802.11ax system. Further, the AP may be a device supporting multiple WLAN technologies such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.
非接入点类的站点(英文:None Access Point Station,简称:Non-AP STA),可以是无线通讯芯片、无线传感器或无线通信终端。例如:支持WiFi通讯功能的移动电话、支持WiFi通讯功能的平板电脑、支持WiFi通讯功能的机顶盒、支持WiFi通讯功能的智能电视、支持WiFi通讯功能的智能可穿戴设备、支持WiFi通讯功能的车载通信设备和支持WiFi通讯功能的计算机。可选地,STA可以支持802.11ax制式,进一步可选地,该站点支持802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式。 A non-access point class (English: None Access Point Station, referred to as Non-AP STA), which can be a wireless communication chip, a wireless sensor, or a wireless communication terminal. For example: mobile phone supporting WiFi communication function, tablet computer supporting WiFi communication function, set-top box supporting WiFi communication function, smart TV supporting WiFi communication function, smart wearable device supporting WiFi communication function, and vehicle communication supporting WiFi communication function Devices and computers that support WiFi communication. Optionally, the STA can support the 802.11ax system. Further optionally, the station supports multiple WLAN systems such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.
随着无线局域网WLAN标准的演进,IEEE802.11工作组正在筹备以低功耗唤醒接收机(Low Power Wake Up Receiver,LP-WUR)为核心技术用以降低功耗的802.11标准研究和制定工作。所述802.11标准已于2016年6月在IEEE成立SG(Study Group,学习组),预计2016年年底成立TG(Task Group,工作组),项目简称为WUR。With the evolution of the WLAN standard for wireless LANs, the IEEE 802.11 working group is preparing for the research and development of the 802.11 standard with low power Wake Up Receiver (LP-WUR) as the core technology to reduce power consumption. The 802.11 standard was established in June 2016 in the IEEE (Study Group, Learning Group). It is expected that the TG (Task Group) will be established by the end of 2016. The project is referred to as WUR.
在WiFi网络中,设备相当一部分能量浪费在无接收信号时的监听(idle listening),当前传统802.11协议(802.11 b/a/g/n/ac等)中相关解决方案集中在优化设备休眠策略。如图2第一个时间轴所示,当设备(如工作站,STA,Station)没有消息收发时(如No data阶段),若持续监听信道(即idle listening)将会消耗可观的能量。因此图2第二个时间轴中引入了休眠机制(Sleep Schedule),使得STA在无数据收发时可以进入深度休眠(Deep Sleep),以减少持续idle listening的能耗。但是当STA处于深度休眠时AP无法与STA通信,只有等到STA苏醒后两者之间才能进行传输,这可能会导致一定的时延(latency)。为了避免休眠机制导致的高时延,STA通常会遵循一定的休眠策略不时醒来检查有无数据需要接收,然而这又降低了STA的休眠效率(不时苏醒但没有有用数据需要收发,相较长时间休眠会消耗更多能量)。In a WiFi network, a considerable part of the energy of the device is wasted in the idle listening mode. The related solutions in the current traditional 802.11 protocol (802.11 b/a/g/n/ac, etc.) focus on optimizing the device sleep strategy. As shown in the first timeline of Figure 2, when the device (such as workstation, STA, Station) has no messaging (such as No data phase), if the continuous listening channel (ie idle listening) will consume considerable energy. Therefore, the Sleep Schedule is introduced in the second time axis of FIG. 2, so that the STA can enter Deep Sleep when there is no data transmission and reception, so as to reduce the energy consumption of the continuous idle listening. However, when the STA is in deep sleep, the AP cannot communicate with the STA, and only after the STA wakes up can the transmission be between the two, which may cause a certain delay. In order to avoid the high latency caused by the dormancy mechanism, the STA usually wakes up from time to time to check whether there is data to receive, but this reduces the sleep efficiency of the STA (from time to time but no useful data needs to be sent and received, longer) Time sleep consumes more energy).
除了优化休眠策略外,减少设备idle listening能量浪费的另一条技术途径是使用LP-WUR(这里简称为WUR)。其核心思想是接收端设备(如STA)除包含传统802.11收发端(802.11 main radio,802.11主收发模块,WiFi主收发模块)外,新增低功耗唤醒接收机(WUR)部分,如图3所示,当802.11主收发模块进入深度休眠后,低功耗的WUR苏醒开始工作。如果其他设备(如图中左侧的AP)需要与带有WUR和802.11主收发模块的设备(如图中右侧的STA)通信,AP首先给WUR发送WUR唤醒帧(WUP,Wake Up Packet),WUR正确收到发给自己的WUP后唤醒STA的802.11主收发模块然后自己转入休眠,AP则与苏醒的802.11主收发模块进行通信。当802.11主收发模块与AP通信完成后会进入休眠,同时WUR苏醒又开始侦听是否有发送给自己的WUP,以便唤醒802.11主收发模块。In addition to optimizing the dormancy strategy, another technical way to reduce the waste of device idle listening energy is to use LP-WUR (herein referred to as WUR). The core idea is that the receiving device (such as STA) includes a new low-power wake-up receiver (WUR) part, in addition to the traditional 802.11 main radio (802.11 main radio, 802.11 main transceiver module, WiFi main transceiver module), as shown in Figure 3. As shown, when the 802.11 master transceiver module enters deep sleep, the low-power WUR wake-up begins to work. If other devices (such as the AP on the left side of the figure) need to communicate with devices with WUR and 802.11 master transceiver modules (STAs on the right side in the figure), the AP first sends WUR wake-up frames (WUP, Wake Up Packet) to WUR. After the WUR correctly receives the WUP sent to itself, it wakes up the STA's 802.11 master transceiver module and then goes to sleep itself. The AP communicates with the awake 802.11 master transceiver module. When the 802.11 main transceiver module communicates with the AP, it will go to sleep. At the same time, the WUR wakes up and starts to listen to whether there is a WUP sent to itself to wake up the 802.11 main transceiver module.
该技术采用了低功耗的WUR代替802.11主收发模块在媒介空闲时侦听信道(这里期望WUR侦听/接收状态的能耗约为802.11主收发模块的0.1~1%,即小于100uW),能够有效降低设备idle listening时能量的浪费。The technology uses a low-power WUR instead of the 802.11 main transceiver module to listen to the channel when the medium is idle (the power consumption of the WUR listening/receiving state is expected to be about 0.1 to 1% of the 802.11 main transceiver module, that is, less than 100 uW). Can effectively reduce the waste of energy when the device idle listening.
而WUR为了实现低功耗,其电路构造、帧结构设计(如WUP)等需要较为简单、以及低复杂度。比如WUR电路结构可能仅仅包含能量检测(energy detect)和射频(RF,radio frequency)部分,因此无法解调一些复杂的调制方式。为此WUP可能采用实现简单的二进制振幅键控(On-Off Keying,OOK)调制方式或频移键控(Frequency Shift Keying,FSK)。In order to achieve low power consumption, WUR needs to be simpler and less complicated in terms of circuit structure and frame structure design (such as WUP). For example, the WUR circuit structure may only include energy detection and radio frequency (RF) components, so it is impossible to demodulate some complex modulation methods. For this reason, the WUP may adopt a simple On-Off Keying (OOK) modulation method or Frequency Shift Keying (FSK).
而一种可能的WUP帧结构如图9所示,前面为Legacy 802.11 preamble(传统802.11先导),可以被周边其他802.11设备听懂(听到该先导的周边802.11设备在一段时间内不会抢占信道),用来保护唤醒帧后续部分不会被传统802.11设备干扰。后面为WUP的payload(有效载荷)部分,采用OOK调制,只有WUR才能听懂。该部分可能包括唤醒先导(Wake-Up Preamble,用于识别WUP信号)、MAC Header(包括WUR ID,用于区分不同的WUR)、frame body(帧载体,可承载一些其他信息),FCS(Frame Check Sequence,帧校验序列,用来确保收到的数据与发送时的数据一样)。这里WUR ID信息可以是部分或者完整的站点关联标识,或AP分配该站点的WUR的标识,或者站点的接收MAC地址 或者部分接收MAC地址,或其他可以区分不同站点的WUR的信息。另外,WUR负载部分可以为窄带传输,即与基于20M带宽为基本单元传输的802.11传统前导码不同,比如说该窄带可以1M,2M,4M,8M,16M等。WUR负载部分也可以基于基于20M带宽为基本单元传输。A possible WUP frame structure is shown in Figure 9. The front is Legacy 802.11 preamble (traditional 802.11 preamble), which can be understood by other 802.11 devices in the vicinity (the peripheral 802.11 device that hears the pilot does not preempt the channel for a period of time). ), used to protect subsequent parts of the wake-up frame from interference by traditional 802.11 devices. The part of the payload (payload) of the WUP is OOK modulation, which can only be understood by WUR. This part may include Wake-Up Preamble (for identifying WUP signals), MAC Header (including WUR ID for distinguishing different WURs), frame body (frame carrier, which can carry some other information), FCS (Frame) Check Sequence, a frame check sequence, is used to ensure that the received data is the same as the data sent. Here, the WUR ID information may be a partial or complete site association identifier, or an identifier of the WUR to which the AP allocates the site, or a receiving MAC address of the site. Or partially receive the MAC address, or other information that can distinguish the WUR of different sites. In addition, the WUR payload portion may be narrowband transmission, that is, different from the 802.11 conventional preamble transmitted based on the 20M bandwidth for the basic unit, for example, the narrowband may be 1M, 2M, 4M, 8M, 16M, and the like. The WUR payload portion can also be based on a 20M bandwidth based transmission.
图10显示了另一种可能的WUP帧结构,它包括802.11传统前导码,唤醒前导码,信令字段(用来携带一些物理层信令,比如AP标识,WUR ID,调制与编码指示等),MAC头,帧体,帧校验序列。Figure 10 shows another possible WUP frame structure, which includes an 802.11 legacy preamble, a wake-up preamble, and a signaling field (used to carry some physical layer signaling, such as AP identity, WUR ID, modulation and coding indication, etc.) , MAC header, frame body, frame check sequence.
802.11ax引入OFDMA技术,实现点对多点进行同时传输。AP可以同时在多个正交子信道上传输不同数据信号给多个站点,即下行OFDMA;另外,多个站点也可以同时通过多个正交子信道传输数据信号给AP,即上行OFDMA。802.11ax introduces OFDMA technology to achieve point-to-multipoint simultaneous transmission. The AP can simultaneously transmit different data signals to multiple sites on multiple orthogonal subchannels, that is, downlink OFDMA. In addition, multiple stations can simultaneously transmit data signals to the AP through multiple orthogonal subchannels, that is, uplink OFDMA.
本发明实施例主要对唤醒帧结构及内容进行设计,使其具备多站点同时唤醒功能,满足802.11ax多站点同时传输的需求。另外,该唤醒帧仍具有单站点唤醒功能。同时,该唤醒帧还包含将被唤醒的主收发机(比如802.11主收发模块)的接收操作模式指示或接收操作模式请求指示等。The embodiment of the invention mainly designs the structure and content of the wake-up frame, so that it has the multi-site simultaneous wake-up function, and satisfies the requirement of simultaneous transmission of 802.11ax multi-site. In addition, the wake-up frame still has a single-site wake-up function. At the same time, the wake-up frame also includes a receiving operation mode indication or a receiving operation mode request indication of a main transceiver (such as an 802.11 main transceiver module) to be woken up.
请参照图1,为一个典型的WLAN部署场景的系统示意图,包括一个AP和3个关联于该AP的STA,AP可以与STA1、STA2和STA3分别进行通信。需要说明的是,各个STA可以包括如图3所示的结构,即是同时包括802.11主收发模块和LP-WUR模块,LP-WUR模块用于接收AP发送的唤醒帧,并对802.11主收发模块唤醒。Referring to FIG. 1 , a schematic diagram of a typical WLAN deployment scenario includes an AP and three STAs associated with the AP, and the AP can communicate with STA1, STA2, and STA3, respectively. It should be noted that each STA may include the structure shown in FIG. 3, that is, the 802.11 main transceiver module and the LP-WUR module are simultaneously included, and the LP-WUR module is configured to receive the wake-up frame sent by the AP and to the 802.11 main transceiver module. wake.
本发明实施例中,AP向关联于该AP的至少一个站点STA发送唤醒帧,比如向图1中STA1、STA2和STA3中至少一个STA发送唤醒帧,该唤醒帧还用于指示被唤醒的至少一个站点的主收发模块从休眠状态被唤醒后的接收参数,比如接收模式指示、被唤醒的时间指示等等。当STA的主收发模块被唤醒后,即可与AP进行通信。值得注意是,本发明不限制是AP发送唤醒帧给non-AP STA,也可以是non-AP STA发送唤醒帧给AP。下面实施例以AP发送唤醒帧给non-AP STA为例。In the embodiment of the present invention, the AP sends a wake-up frame to at least one STA associated with the AP, such as sending a wake-up frame to at least one of STA1, STA2, and STA3 in FIG. 1, and the wake-up frame is further used to indicate at least one that is awakened. The receiving parameters of the master transceiver module of a station after being woken up from the sleep state, such as the receiving mode indication, the time indication of being woken up, and the like. When the STA's main transceiver module is woken up, it can communicate with the AP. It should be noted that the present invention is not limited to the fact that the AP sends the wake-up frame to the non-AP STA, or the non-AP STA sends the wake-up frame to the AP. The following embodiment takes an example in which an AP sends a wake-up frame to a non-AP STA.

For example, as shown in FIG. 11d, if the receiving parameter of the station indicated by the station identifier in the station information 2 is the same as the receiving parameter of the station indicated by the station identifier in the station information 1, the receiving parameter may be omitted in the station information 2.
基于上述两种可选的实施方式中,可能存在四种信息结构(图11a、图11b、图11c以及图11d)中的任意一种或者多种,不同的信息结构代表不同的帧结构类型,上述公共信息中可以包括帧结构类型指示信息,该帧结构类型指示信息用于指示唤醒帧的帧结构类型,比如,该帧结构类型指示信息使用两个比特字符。Based on the above two alternative embodiments, there may be any one or more of four information structures (FIG. 11a, FIG. 11b, FIG. 11c, and FIG. 11d), and different information structures represent different frame structure types. The foregoing public information may include frame structure type indication information, where the frame structure type indication information is used to indicate a frame structure type of the wake-up frame. For example, the frame structure type indication information uses two bit characters.
若所述唤醒帧的帧结构类型为单组信息结构,则所述唤醒帧包括一个所述组信息(如图11b所示);若所述唤醒帧的帧结构类型为多组信息结构,则所述唤醒帧包括至少两个所述组信息(如图11a所示);若所述唤醒帧的帧结构类型为单站点信息结构,则所述唤醒帧包括一个所述站点信息(如图11c所示);若所述唤醒帧的帧结构类型为多站点信息结构;则若所述唤醒帧包括至少两个所述站点信息(如图11d所示)。If the frame structure type of the wake-up frame is a single-group information structure, the wake-up frame includes one of the group information (as shown in FIG. 11b); if the frame structure type of the wake-up frame is a multi-group information structure, The wake-up frame includes at least two pieces of group information (as shown in FIG. 11a); if the frame structure type of the wake-up frame is a single-site information structure, the wake-up frame includes one piece of the site information (as shown in FIG. 11c).

可选的,上述公共信息还可以包括长度信息,该长度信息用于指示唤醒帧的结束位置,比如,长度信息用来指示公有信息后到帧结尾的长度,或者唤醒帧的唤醒前导码后(或唤 醒前导码开始)到帧结尾的长度,或者若该唤醒帧为媒体接入控制层(Medium Access Control,MAC)帧,该长度信息还可以是MAC头后到帧结尾的长度等信息,该长度信息用于指示接收站点该唤醒帧的结尾处。可选的,若组信息(或站点信息)长度固定,该长度字段也可以是组信息(或者站点信息)的个数指示。Optionally, the public information may further include length information, where the length information is used to indicate an end position of the wake-up frame, for example, the length information is used to indicate the length of the public information to the end of the frame, or the wake-up preamble of the wake-up frame ( Or call The length of the frame to the end of the frame, or if the wake-up frame is a Medium Access Control (MAC) frame, the length information may also be information such as the length from the MAC header to the end of the frame, and the length. The information is used to indicate to the receiving station at the end of the wake-up frame. Optionally, if the group information (or the site information) has a fixed length, the length field may also be an indication of the number of group information (or site information).
可选的,上述公共信息还可以包括唤醒后是否使用WUP回复指示,用来告知站点被唤醒后能否发送具有唤醒帧(比如具备确认功能的唤醒帧等)来回复该AP。Optionally, the public information may further include whether the WUP reply indication is used after the wake-up, and is used to notify the station whether the wake-up frame (such as a wake-up frame with an acknowledgement function, etc.) can be sent to reply to the AP after being awake.
可选的,上述公共信息还可以包括时间戳。Optionally, the public information may further include a timestamp.
作为一种可选的实施方式,该唤醒帧可以用来唤醒至少一个站点,也可以用来传输BSS信息参数,该BSS信息参数可以是处于休眠状态的站点的主收发模块所在BSS的信息参数,也可以是处于休眠状态的站点的LP-WUR所在BSS的信息参数,BSS信息参数包括时间戳,信道号,次信道差,频段号,带宽,带宽中心频率,增强分布式信道接入(enhanced distributed channel access,EDCA)参数,信标帧到达时间,信标帧间隔中的至少一种。其中次信道差是指次信道是比主信道频率高还是低的指示,一种实施方式是信道号为主信道号,宽带中心频率包括宽带中心频率1和宽带中心频率2。AP管理的多个唤醒接收机可能工作在不同的信道上,该信道可以窄带。用来唤醒站点的唤醒帧需在唤醒帧所在的信道上传输,而用来传输BSS信息参数的唤醒帧需在多个信道上传输所通知管理唤醒接收机,可以通过分时或同时在多个信道(比如窄带信道)上传输唤醒帧。如果唤醒帧需要包括主收发模块所在BSS的信息参数和LP-WUR所在BSS的信息参数时,则需要用类型或者元素加以区分。As an optional implementation manner, the wake-up frame may be used to wake up at least one station, and may also be used to transmit BSS information parameters, where the BSS information parameter may be an information parameter of a BSS where a primary transceiver module of a station in a dormant state is located. It may also be an information parameter of a BSS where the LP-WUR of the station in the dormant state includes a timestamp, a channel number, a secondary channel difference, a frequency band number, a bandwidth, a bandwidth center frequency, and enhanced distributed channel access (enhanced distributed access). Channel access (EDCA) parameter, at least one of a beacon frame arrival time, and a beacon frame interval. The secondary channel difference refers to an indication that the secondary channel is higher or lower than the primary channel frequency. One implementation manner is that the channel number is the primary channel number, and the broadband center frequency includes the broadband center frequency 1 and the broadband center frequency 2. Multiple wake-up receivers managed by the AP may operate on different channels, which may be narrowband. The wake-up frame used to wake up the station needs to be transmitted on the channel where the wake-up frame is located, and the wake-up frame used to transmit the BSS information parameter needs to be transmitted on multiple channels to notify the management of the wake-up receiver, which can be used in multiple times by time sharing or simultaneously. A wake-up frame is transmitted on a channel, such as a narrowband channel. If the wake-up frame needs to include the information parameter of the BSS where the primary transceiver module is located and the information parameter of the BSS where the LP-WUR is located, it needs to be distinguished by type or element.
本发明实施例采用帧类型指示信息用于指示该唤醒帧的功能,若帧类型指示信息为第一标识,则唤醒帧用来唤醒至少一个站点,该唤醒帧包括用于指示待唤醒的至少一个站点的第一指示信息以及用于指示该至少一个站点的接收参数的第二指示信息,可选的,该唤醒帧还可以包括BSS信息参数,用来告知被唤醒的站点主收发机所在的BSS信息参数,或者最新的BSS信息参数。若帧类型指示信息为第二标识,则唤醒帧用来传输BSS信息参数,该唤醒帧包括用于指示BSS信息参数的第三指示信息。The embodiment of the present invention uses the frame type indication information to indicate the function of the wake-up frame.

AP发送唤醒帧给站点时,该唤醒帧还包括AP最大睡眠时间,用来帮助非关联站点收到该唤醒帧时是否能选择关联该AP。比如说,该站点通常会发送紧急业务,但是收到该AP发送的最大睡眠时间大于自己的容忍度,则站点不选择该AP进行关联。When the AP sends a wake-up frame to the station, the wake-up frame further includes an AP maximum sleep time, which is used to help the non-associated site to associate with the AP when receiving the wake-up frame. For example, the site usually sends emergency services, but if the maximum sleep time sent by the AP is greater than its own tolerance, the site does not select the AP for association.
当WUP帧如图11c所示时,只包含单站点信息。接收参数中包括的唤醒类型也可以包括上述提到的帧类型,即将第一标识替换成接收参数中的唤醒类型。When the WUP frame is as shown in Figure 11c, only single site information is included.

If the frame type indication information indicates that the wakeup frame is used to indicate a BSS information parameter, the sending address in the MAC header is an AP address, and the receiving address is a broadcast address, and the frame body is Only the public field is included in the public information, and the public information includes information such as a time stamp. Optionally, the public information also includes length information.
若帧类型指示信息指示唤醒帧用于唤醒至少一个站点,则MAC头中的发送地址为AP地址,接收地址为单播地址或者广播地址,帧体含有公共字段和单信息字段。公共字段承载的公有信息包括时间戳,帧结构类型指示信息和长度信息,需要说明的是,帧结构类型指示信息为可选信息。If the frame type indication information indicates that the wake-up frame is used to wake 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 includes a common field and a single information field. The public information carried by the public field includes the timestamp, the frame structure type indication information, and the length information. It should be noted that the frame structure type indication information is optional information.
可选的,若帧体为单站点信息结构,即是帧体包括一个站点信息,那么该站点信息可以不含有站点标识,因为此时接收地址可以识别该站点。Optionally, if the frame body is a single-site information structure, that is, the frame body includes a site information, the site information may not include the site identifier, because the receiving address may identify the site at this time.
若唤醒帧为物理帧,如图12所示,该唤醒帧包括传统前导码、唤醒前导码以及第一信令字段SIG1和第二信令字段SIG2,其中,SIG1字段类似于MAC帧中的公共字段,SIG1字段承载公共信息,进一步可选的,该SIG1字段还包括AP的标识,该标识为可以AP的BSS标识符(BSS identifier,BSSID),部分BSSID,BSS color等。第二信令字段SIG2用于承载上述至少一个组信息或者至少一个站点信息,需要说明的是,当SIG1字段和SIG2字段为单站点信息结构,此时该站点信息含有站点标识。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 the public in the MAC frame.

AP生成该唤醒帧后,即发送该唤醒帧,如图6所示,AP发送唤醒帧给单个站点,站点收到唤醒帧后,发送PS poll帧给AP,告诉AP已醒来,然后AP回确认Ack或者直接传送数据给该站点。或者,AP也可以直接在站点被唤醒后,直接发送数据帧给该站点,而无需等候该站点发送PS-Poll帧。After the AP generates the wake-up frame, the AP sends the wake-up frame. As shown in Figure 6, the AP sends the wake-up frame to a single site. After receiving the wake-up frame, the AP sends a PS poll frame to the AP, telling the AP that it has woken up, and then the AP returns. Confirm Ack or transfer data directly to the site. Alternatively, the AP can directly send data frames to the site directly after the site is woken up, without waiting for the station to send PS-Poll frames.
如图7所示,AP发送唤醒帧给多个站点,多个站点收到唤醒帧后,AP发送触发/trigger帧给该多个站点,该触发帧含有资源分配调度信息,多站点收到该触发帧信息后,按照资源调度信息通过OFMDA技术在不同正交子信道上回复PS-Poll帧,告诉AP该站点的主收发模块已被唤醒。As shown in FIG. 7, the AP sends a wake-up frame to multiple sites. After receiving the wake-up frame, the AP sends a trigger/trigger frame to the multiple sites. The trigger frame contains resource allocation scheduling information, and the multi-site receives the After the frame information is triggered, the PS-Poll frame is replied to the different orthogonal subchannels by the OFMDA technology according to the resource scheduling information, and the AP is notified that the primary transceiver module of the station has been woken up.
如图8所示,AP在发完唤醒帧后,在站点的主收发模块被唤醒后,AP直接发送下行OFDMA数据给该多个站点,然后该多个站点回复确认帧。As shown in FIG. 8, after the AP wakes up the frame, after the primary transceiver module of the station is woken up, the AP directly sends downlink OFDMA data to the multiple sites, and then the multiple sites reply to the acknowledgement frame.

By designing the wake-up frame, an indication of wake-up of at least one station and receiving parameters can be achieved.
另外如果AP配备唤醒接收机,处于节能的目的,AP的主收发机也会睡眠。所以本发 明提到的提到的实施例也同样适用非AP站点唤醒AP,但是非AP站点发送的唤醒帧不包括BSS信息参数。In addition, if the AP is equipped with a wake-up receiver and is energy-saving, the AP's main transceiver will also sleep.
