  • TWT is a technology for energy saving defined by wireless fidelity (WiFi) 6.
  • WiFi wireless fidelity
  • the core idea of TWT is to set some periodic time periods so that some devices only need to remain active during these TWT service periods (TWT SP) and can sleep at other times, thereby achieving energy saving.
  • TWT is divided into unicast TWT (individual TWT) and broadcast TWT (broadcast TWT).
  • unicast TWT each station (STA) can establish a TWT protocol with the access point (AP) individually, so each STA can have its own active time period and sleep time period.
  • broadcast TWT AP can establish a common TWT protocol for a group of STAs, and multiple STAs work in the same active time period and sleep in other time periods.

  • Figure 1 is a schematic diagram of the working principle of r-TWT. As shown in Figure 1, EHT AP1 broadcasts one or more r-TWT SPs through beacon frames or probe response frames. After receiving the r-TWT, STA1 and STA2 decide whether to join the r-TWT group.
  • STA1 sends a request to EHT AP1 to join the r-TWT group, and EHT AP1 sends a response to STA1 agreeing to join the r-TWT group, then STA1 is an EHT station in the r-TWT group. If STA2 does not send a request to EHT AP1 to join the r-TWT group, or STA2 sends a request to EHT AP1 to join the r-TWT group, but EHT AP1 does not agree to STA1 joining the r-TWT group, then STA2 is an EHT station outside the r-TWT group.

  • STA1 can send a data frame to EHT AP1
  • EHT AP1 can feedback a confirmation frame to STA1 based on the received data frame to achieve data transmission.
  • EHT AP1 instructs the EHT STAs belonging to the r-TWT group to ignore the above-mentioned silence interval through the silence element, and then compete for the channel after the start of r-TWT SP.
  • the stations that do not belong to the r-TWT group or other Non-EHT stations need to maintain silence for one TU from the start time of r-TWT SP according to the silence interval. That is, EHT STA1 can ignore the above-mentioned silence interval and compete for the channel after the start of r-TWT SP, while EHT STA2 and Non-EHT STA3 need to maintain silence for one TU from the start time of r-TWT SP according to the silence interval.
  • EHT STA2 and Non-EHT do not transmit data within one TU from the start time of r-TWT SP to reduce the number of stations competing for the channel in cell 1, thereby increasing the probability of the station EHT STA1 in the group competing for the channel.

In other words, there is an overlap in the communication range between cell 1 and cell 2.
  • STA4 and STA6 in cell 2 receive the beacon frame broadcast by EHT AP1 in cell 1, in order to avoid interfering with STA1's access to the r-TWT channel, STA4, STA5 and STA6 in cell 2 also need to remain silent for one TU from the start time of the r-TWT SP.

Description

通信方法及装置
本申请要求于2022年11月10日提交国家知识产权局、申请号为202211408438.4、申请名称为“通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
目前，现有的目标限定唤醒时间(target wakeup time，TWT)信息帧可以用来对本小区的单播TWT(individual TWT)或者所有的TWT进行暂停，其中，所有TWT包括单播TWT和广播TWT。小区为一个网络设备提供服务的区域，或者说一个网络设备的信号覆盖的一个物理区域。
然而，本小区这种工作方式会影响其他小区的通信，导致其他小区的通信资源利用率降低。
发明内容
本申请实施例提供一种通信方法及装置，用以提高其他小区的通信资源利用率。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种通信方法，该方法包括：在第一网络设备与至少一个终端的第一广播目标唤醒时间TWT暂停的情况下，第一网络设备获取暂停信息，并向第二网络设备发送暂停信息。其中，至少一个终端是第一网络设备的小区内的终端，暂停信息用于指示第一广播TWT暂停；第二网络设备的小区与第一网络设备的小区存在通信范围的交叠。
基于第一方面所述的方法可知，由于第一网络设备的小区与第二网络设备的小区存在通信范围的交叠，导致第一网络设备的小区的通信会对第二网络设备的小区产生影响。这种情况下，如果第一网络设备的小区内的通信暂停，如该小区内的第一网络设备与至少一个终端的第一TWT暂停，则第一网络设备可以通过暂停信息，通知第二网络设备的小区，以便第二网络设备的小区可以恢复通信，从而可以提高第二网络设备的小区的通信资源利用率。
一种可能的设计方案中，暂停信息包括如下至少一项：第一广播TWT的标识，以及第一广播TWT的暂停时间。其中，第一广播TWT的标识可以承载在广播TWT标识域(broadcast TWT ID)中，第一广播TWT的标识可以为第一广播TWT的ID，用于指示暂停的广播TWT的标识为第一广播TWT。第一广播TWT的暂停时间可以承载在下一个TWT(next TWT)中，第一广播TWT的暂停时间可以包括第一广播TWT暂停的时长，以及开始暂停的时间、结束暂停的时间等信息。
可以理解，在有多个广播TWT需要暂停的情况下，第一网络设备需要根据每个广播TWT的标识以及暂停时间联合指示具体是哪一个广播TWT被暂停以及暂停多久，以避免第二网络设备对暂停的广播TWT进行误识别或者误处理。当然，若只有一个广播TWT需要暂停的情况下，暂停信息中可以不携带广播TWT的标识。若有多个广播TWT需要暂停的情况下，除了第一广播TWT之外，该暂停信息中的还可以包括第二广播TWT、第三广播TWT等标识。若每个暂停广播TWT暂停时间不同，暂停信息中还可以携带每个暂停广播TWT的暂停时间。
一种可能的设计方案中，暂停信息包括如下至少一项：第一比特位图，以及第一广播TWT的暂停时间，其中，第一比特位图可以承载在广播TWT标识位图(broadcast TWT ID bitmap)中，用于指示第一广播TWT暂停。第一广播TWT的暂停时间可以承载在下一个TWT中，第一广播TWT的暂停时间可以包括第一广播TWT暂停的时长，以及开始暂停的时间、结束暂停的时间等信息。
可选地，第一比特位图包括第一网络设备的多个广播TWT对应的多个比特，多个比特中的第一比特在多个比特的位置用于指示第一广播TWT，第一比特的取值用于指示第一广播TWT暂停。
可以看出，由于每个比特位都可以对应指示一个广播TWT是否被暂停，那么多个比特的位置就可以同时指示多个暂停的广播TWT，相较于上述设计方案，第一网络设备不需要在暂停信息中携带多个广播TWT标识，从而可以节约开销。并且，多个暂停的广播TWT可以共享同一个暂停 时间，从而可以减少暂停信息的发送次数，进一步节约开销。
第二方面，提供一种通信方法，该方法包括：第二网络设备接收来自第一网络设备的暂停信息，并根据暂停信息，向第二网络设备的小区内的至少一个终端发送第一指示信息。其中，暂停信息用于指示第一网络设备的第一TWT暂停，第一广播TWT暂停是指：第一网络设备与第一网络设备的小区内的终端的广播TWT暂停，第一网络设备的小区与第二网络设备的小区存在通信范围的交叠；第一指示信息用于指示至少一个终端能进行数据传输。
基于第二方面所述的方法可知，由于第一网络设备的小区与第二网络设备的小区存在通信范围的交叠，导致第一网络设备的小区的通信会对第二网络设备的小区产生影响。这种情况下，如果第一网络设备的小区内的通信暂停，如该小区内的第一网络设备与至少一个终端的第一TWT暂停，则第一网络设备可以通过暂停信息，通知第二网络设备的小区，以便第二网络设备的小区可以恢复通信，例如，第二网络设备可以通过第一指示信息指示第二网络设备的小区内的终端可以不需要保持静默，而执行数据的传输，从而可以提高第二网络设备的小区的通信资源利用率。
一种可能的设计方案中，暂停信息包括如下至少一项：第一广播TWT的标识，以及第一广播TWT的暂停时间。

一种可能的设计方案中，第一指示信息用于指示至少一个终端在第一时间能进行数据传输，第一时间是在第一广播TWT没有暂停的情况下，第一网络设备建立第一广播TWT服务阶段的时间。也就是说，在第一广播TWT没有暂停时，第一网络设备需要在第一时间内接入信道并进行数据传输，此时第二网络设备中的终端在第一时间内的信道接入之前不能进行数据的传输。在第一广播TWT暂停的情况下，第二网络设备可以根据第一指示信息指示至少一个终端在第一时间可以不需要保持静默，而执行数据的传输，从而可以提高资源的利用率。
可选地，第二网络设备建立有第二广播TWT，第二广播TWT是不允许至少一个终端与第二网络设备建立广播TWT服务阶段的广播TWT，第二广播TWT与第一广播TWT的服务阶段的时间段相同，第一指示信息用于第二广播TWT被取消或者暂停。可以理解，第二网络设备可以建立与第一广播TWT的服务阶段对齐的第二广播TWT，并且第二广播TWT不允许终端接入，从而可以指示第二网络设备中的终端在第一广播TWT的信道接入时保持静默，避免对第一广播TWT信道建立产生干扰，以实现对第一广播TWT信道接入进行保护。在此基础上，第二网络设备接收到第一广播TWT的暂停信息后，第二网络设备可以直接通过第一指示信息指示第二广播TWT被取消或者暂停，使得至少一个终端可以在第一时间可以不需要保持静默，而执行数据的传输，从而可以提高资源的利用率。
一种可能的设计方案中，所述方法还包括：在第二广播TWT被取消的情况下，第二网络设备向至少一个终端发送第二指示信息。其中，第二指示信息用于指示第一广播TWT恢复后建立第三广播TWT；第三广播TWT与第一广播TWT服务阶段的时间段相同，第三广播TWT是不允许至少一个终端与第二网络设备建立广播TWT服务阶段的广播TWT。在第一广播TWT的恢复的情况下，第二网络设备通过第二指示信息重建第二广播TWT，从而继续对第一广播TWT的信道接入进行保护。
第二方面所述的方法的其他技术效果可以参考第一方面所述的方法的技术效果，此处不再赘述。
第三方面，提供一种通信方法，该方法包括：第二网络设备的小区内的第一终端接收来自第二网络设备的第一指示信息，并进行数据传输。其中，第一指示信息用于指示第二网络设备的小区内的至少一个终端能进行数据传输，第二网络设备的小区与第一网络设备的小区存在通信范围的交叠；第一网络设备的第一广播TWT暂停，第一广播TWT暂停是指：第一网络设备与第一网络设备的小区内的终端的广播TWT暂停。

具体实施方式
方便理解，下面先介绍本申请实施例所涉及的技术术语。
1.TWT：
TWT是无线通信技术(wireless fidelity，WiFi)6定义的一种用于节能的技术。TWT的核心思想是通过设置一些周期性的时间段，使得某些设备只需要在这些TWT服务阶段(service period，TWT SP)中保持活跃状态，在其他的时间可以进行休眠，从而达到节能的目的。
TWT分为单播TWT(individual TWT)和广播TWT(broadcast TWT)。在单播TWT中，每个站点(station，STA)可以单独与接入点(access point，AP)建立一个TWT协议，因此，每个STA可以有自己的活跃时间段和休眠时间段。在广播TWT中，AP可以为一组STA建立一个公用的TWT协议，多个STA在相同的活跃时间段进行工作，在其他时间段进行休眠。
具体的，广播TWT的一种情况是限定目标唤醒时间(restricted target wakeup time，r-TWT)，r-TWT是无线局域网(wireless local area network，WLAN)的802.11be定义的一种新的保障低时延业务的机制，802.11be叫做极高吞吐率(extremely high throughput，EHT)，而对于802.11be之前的标准，如IEEE 802.11a、IEEE 802.11ac、IEEE 802.11ax等统称叫做非极高吞吐率(non-high throughput，Non-EHT)。对于某个小区而言，该小区可以是由极高吞吐量接入点(EHT AP)提供服务的区域，或者说极高吞吐量接入点的信号覆盖的一个物理区域，例如，小区1为EHT AP1提供服务的区域，小区1包括EHT AP1和三个STA。其中，STA1和STA2为EHT站点，STA3为Non-EHT站点。图1为r-TWT的工作原理示意图，如图1所示，EHT AP1通过信标帧或(beacon)或者探测响应(probe response)帧广播一个或者多个r-TWT SP，STA1和STA2在接收到r-TWT后，决定是否加入该r-TWT组。
若STA1向EHT AP1发送加入r-TWT组的请求，且EHT AP1向STA1发送同意加入r-TWT组的响应，此时STA1为r-TWT的组内EHT站点。STA2没有向EHT AP1发送加入r-TWT组的请求，或STA2向EHT AP1发送加入r-TWT组的请求，但EHT AP1不同意STA1加入r-TWT组，此时STA2为r-TWT的组外EHT站点。
在STA1、STA2和STA3接收到来自EHT AP1广播的任意一个r-TWT SP后，STA1、STA2和STA3在r-TWT SP开始之前提前结束传输机会。此外，EHT AP1可以在信标帧或探测响应帧中携带静默元素(quiet element)，该静默元素可以包括与r-TWT SP起始时间对齐的静默间隔(quiet interval)，时长为一个时间单位(time uint，TU)，也可以称为1毫秒(ms)，1TU＝1024微秒(us)。例如，EHT AP1与STA1在r-TWT SP起始时间进行信道接入后，STA1可以向EHT AP1发送数据帧，EHT AP1可以根据接收到的数据帧向STA1反馈确认帧，以实现数据的传输。
EHT AP1通过该静默元素指示属于该r-TWT组的EHT STA忽略掉上述的静默间隔，进而在r-TWT SP开始之后竞争信道，不属于该r-TWT组的站点或其他的Non-EHT站点，需要根据静默间隔从r-TWT SP起始时间起保持一个TU的静默。也即EHT STA1可以忽略掉上述的静默间隔，并且在r-TWT SP开始之后竞争信道，而EHT STA2和Non-EHT STA3需要根据静默间隔从r-TWT SP起始时间起保持一个TU的静默，也就是说，EHT STA2和Non-EHT在r-TWT SP起始时间起的一个TU内不进行数据传输，以减少小区1中竞争信道的站点数量，从而提高组内站点EHT STA1竞争到信道的概率。
2.重叠基础服务集(verlapping basic service sets)：
OBSS是指不同AP提供服务区域、或信号覆盖的物理区域有交叠。例如，小区1包括EHT AP1、STA1、STA2和STA3，小区2包括EHT AP2、STA4、STA5和STA6，若HT AP1与EHT AP2提供通信服务的区域，或者信号覆盖的物理区域至少重叠有部分重叠，则小区1与小区2为OBSS。也就是说，小区1与小区2存在通信范围的交叠，在这种情况下，在小区2的STA4、STA5和STA6在接收到小区1的EHT AP1广播的信标帧后，STA4、STA5和STA6为了避免对STA1接入r-TWT信道产生干扰，小区2的STA4、STA5和STA6也需要在r-TWT SP起始时间起保持一个TU的静默。
然而，该r-TWT可能在没有数据传输时产生暂停，此时EHT AP1与STA1可以通过交互目标唤醒时间信息帧(target wakeup time information frame)来触发r-TWT SP暂停，目标唤醒时间信 息帧包括TWT信息域(TWT information field)，图2a为TWT信息域的帧结构示意图，如图2a所示，TWT信息域包括TWT流标识(TWT flow identifier)、要求应答(response requested)、下一个TWT要求(next TWT request)、下一个TWT子域大小(next TWT subfield size)、所有TWT(All TWT)和下一个TWT(Next TWT)等。
其中，TWT流标识用于指示单播TWT的标识，共占用3个比特。
要求应答(response requested)用于指示是否要求对端发送TWT信息帧，共占用1个比特。例如，要求应答置1可以指示要求对端发送TWT信息帧，要求应答置0可以指示要求对端不发送TWT信息帧。
下一个TWT要求用于指示是否要求对端发送一个含有长度不为0的下一个TWT域的TWT信息帧，共占用1个比特。例如，下一个TWT要求域置1可以指示要求对端发送一个含有长度不为0的下一个TWT域的TWT信息帧，下一个TWT要求域置0可以指示要求对端发送一个含有长度为0的下一个TWT域的TWT信息帧。
下一个TWT子域大小用于指示下一个TWT域的长度，共占用2个比特。例如，下一个TWT子域大小取值为0用于指示下一个TWT域的长度为0个比特；下一个TWT子域大小取值为1用于指示下一个TWT域的长度为32个比特；下一个TWT子域大小取值为2用于指示下一个TWT域的长度为48个比特；下一个TWT子域大小取值为3用于指示下一个TWT域的长度为64个比特。
所有TWT用于指示本TWT信息帧指示的所有的TWT是否全部暂停，共占用1个比特。例如，所有TWT置1用于指示本TWT信息帧指示的所有的TWT全部暂停，所有TWT包括单播TWT和广播TWT；所有TWT置0用于指示本TWT信息帧指示的所有的TWT没有全部暂停，此时可以通过TWT流标识指示特定的一个单播TWT暂停。
下一个TWT用于指示TWT暂停的时间，可以占用0、32、48以及64比特。
若EHT AP1向STA1发送唤醒时间信息帧，该唤醒时间信息帧的要求应答置1，下一个TWT要求置1，下一个TWT子域大小取值为0，下一个TWT的长度为0个比特，此时AP1向STA1发送唤醒时间信息帧中并不携带TWT暂停的时间，则STA1可以向AP1发送一个含有长度不为0的下一个TWT域的TWT信息帧，以告知AP1侧TWT暂停的时间。
若EHT AP1向STA1发送唤醒时间信息帧，该唤醒时间信息帧的要求应答置1，下一个TWT要求置1，下一个TWT子域大小取值可以为1、2或3，下一个TWT域的长度不为0个比特，此时AP1向STA1发送的唤醒时间信息帧中携带有TWT暂停的时间，则STA1可以向AP1发送一个含有长度不为0的下一个TWT的TWT信息帧。其中，STA1向AP1反馈的TWT信息帧与AP1向STA1发送的TWT信息帧中指示的TWT暂停时间相同。
若EHT AP1向STA1发送唤醒时间信息帧，该唤醒时间信息帧的要求应答置1，下一个TWT要求置0，下一个TWT子域大小取值为1、2或3，下一个TWT域的长度不为0个比特，此时AP1向STA1发送的唤醒时间信息帧中携带有TWT暂停的时间，则STA1可以向AP1发送一个含有长度为0的下一个TWT域的TWT信息帧。其中，STA1向AP1反馈的TWT信息帧与AP1向STA1发送的TWT信息帧中指示的TWT暂停时间相同。
若EHT AP1向STA1发送唤醒时间信息帧，该唤醒时间信息帧的要求应答置0，则下一个TWT要求域置0或置1，STA1均不向AP1反馈TWT信息帧，此时下一个TWT子域大小取值不能为0，也就是说，EHT AP1向STA1发送的TWT信息帧中须携带TWT暂停时间。
图2b为广播目标唤醒时间信息子域的结构示意图，如图2b所示，广播目标唤醒时间信息子域可以包括限定TWT流量信息子域存在指示(restricted TWT traffic information present)、预留(reserved)、广播TWT标识域(broadcast TWT ID)、广播TWT持续时长(broadcast TWT persistence)等。其中，限定TWT流量信息子域存在指示置1用于指示TWT元素包含下面介绍的图2c所示的限定目标唤醒时间信息子域；限定TWT流量信息子域存在指示置0用于指示TWT元素不包含下面介绍的图2c所示的限定目标唤醒时间信息子域。广播目标唤醒时间信息子域具体含义可以参照现有技术中对广播目标唤醒时间信息子域的相关介绍，在此不做赘述。
图2c为限定目标唤醒时间信息子域的结构示意图，如图2c所示，限定目标唤醒时间信息子 域包括流量信息控制(traffic information control)、限定TWT下行TID位图(restricted TWT DL TID bitmap)、限定TWT上行TID位图(restricted TWT UL TID bitmap)，其中，限定TWT下行TID位图包括下行业务标识位图生效与否(DL TID bitmap valid)、上行业务标识位图生效与否(UL TID bitmap valid)和预留。限定目标唤醒时间信息子域具体含义可以参照现有技术中对限定目标唤醒时间信息子域的相关介绍，在此不做赘述。
然而，上述TWT信息帧可以对本小区的单播TWT或者所有TWT进行暂停。但是，与本小区至少有部分重叠覆盖区域的其他外小区并不知道TWT的暂停信息，此时，外小区的STA仍然会在本小区的已经暂停的TWT的起始时间起保持静默，从而影响其他小区的数据传输效率，导致外小区的资源利用率降低。
例如，EHT AP1向STA1发送TWT信息帧，以指示小区1的r-TWT进行暂停。但是，EHT AP2并不知道r-TWT的暂停信息，此时，小区2的STA4、STA5和STA6仍然会在小区1的已经暂停的r-TWT的起始时间起保持静默，从而影响小区2的数据传输效率，导致小区2的通信资源利用率降低。
针对上述技术问题，本申请实施例提出了如下技术方案，用以提高其他小区的通信资源利用率。
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如无线保真(wireless fidelity，WiFi)系统，车到任意物体(vehicle to everything，V2X)通信系统、设备间(device-todevie，D2D)通信系统、车联网通信系统、第四代(4th generation，4G)移动通信系统，如长期演进(long term evolution，LTE)系统、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、5G，如新空口(new radio，NR)系统，以及未来的通信系统等。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
另外，在本申请实施例中，“示例的”、“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例中，“信息(information)”，“信号(signal)”，“消息(message)”，“信道(channel)”、“信令(singaling)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是匹配的。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是匹配的。此外，本申请提到的“/”可以用于表示“或”的关系。
可以理解，在本申请中，“指示”可以包括直接指示、间接指示、显示指示、隐式指示。当描述某一指示信息用于指示A时，可以理解为该指示信息携带A、直接指示A，或间接指示A。
本申请中，指示信息所指示的信息，称为待指示信息。在具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等，也可以通过指示其他信息来间接指示待指示信息，其中，该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
待指示信息可以作为一个整体一起发送，也可以分成多个子信息分开发送，而且这些子信息的发送周期和/或发送时机可以相同，也可以不同。具体发送方法本申请不进行限定。其中，这些子信息的发送周期和/或发送时机可以是预先定义的，例如根据协议预先定义的，也可以是发射端设备通过向接收端设备发送配置信息来配置的。本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
为便于理解本申请实施例，首先以图3中示出的通信系统为例详细说明适用于本申请实施例的通信系统。示例性的，图3为本申请实施例提供的通信方法所适用的一种通信系统的架构示意图。
如图3所示，该通信系统主要包括：网络设备和终端。
其中，网络设备可以是无线保真(wireless fidelity，WiFi)系统中的AP，无线中继节点、无线回传节点、各种形式的宏基站、微基站(也称为小站)、中继站、接入点、可穿戴设备、车载设备等等。或者，在下一代移动通信系统中，该网络设备也可以有其他命名方式，其均涵盖在本申请实施例的保护范围以内，本申请对此不做任何限定。
终端可以也称为STA，具体可以是具有收发功能的终端，或为可设置于该终端的芯片或芯片系统。该终端也可以称为用户设备(uesr equipment，UE)、接入终端、用户单元(subscriber unit)、用户站、移动站(mobile station，MS)、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端可以是手机(mobile phone)、蜂窝电话(cellular phone)、智能电话(smart phone)、平板电脑(Pad)、无线数据卡、个人数字助理电脑(personal digital assistant，PDA)、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、车载终端、具有终端功能的路边单元(road side unit，RSU)等。本申请的终端还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元。
本申请实施例中，网络设备可以有多个，如包括第一网络设备和第二网络设备。终端可以是接入第二网络设备的小区的第一终端，也称为第二网络设备的小区内的第一终端。
由于第一网络设备的小区与第二网络设备的小区存在通信范围的交叠，导致第一网络设备的小区的通信会对第二网络设备的小区产生影响。这种情况下，如果第一网络设备的小区内的通信暂停，如该小区内的第一网络设备与至少一个终端的第一TWT暂停。此时，第一网络设备可以通过暂停信息，通知第二网络设备的小区，以便第二网络设备的小区可以根据该暂停信息，向第二网络设备的小区内的至少一个终端，如第二网络设备的小区内的第一终端，发送第一指示信息，以指示第一终端可以不需要保持静默，可以执行数据的传输，从而可以提高第二网络设备的小区的通信资源利用率。
方便理解，下面将结合图4-图12对本申请实施例提供的通信方法进行具体阐述。
示例性的，图4为本申请实施例提供的通信方法的流程示意图。该方法可以适用于上述通信系统中第一网络设备、第二网络设备以及第一终端之间的通信。
具体的，如图4所示，该通信方法的流程如下：
S401：在第一网络设备与至少一个终端的第一广播目标唤醒时间TWT暂停的情况下，第一网络设备获取暂停信息。
其中，至少一个终端是第一网络设备的小区内的终端，记为至少一个终端#1。第一网络设备的小区是指该第一网络设备提供通信服务的区域，或者说第一网络设备的信号覆盖的一个物理区域，具体参考上述的相关介绍，不再赘述。
第一广播TWT可以是至少一个终端#1与第一网络设备建立的传输服务。具体来说，第一网络设备的小区可以提供广播TWT服务，至少一个终端#1可以参与广播TWT服务，建立第一广播TWT，例如，至少一个终端#1可以通过信道竞争的方式接入第一广播TWT的信道，从而建立第一广播TWT。之后，至少一个终端#1可以通过第一广播TWT与第一网络设备进行通信。第一广播TWT可以包括多个r-TWT SP，也即第一广播TWT可以是周期的，例如，第一网络设备可以每间隔一个周期T，与至少一个终端#1建立一个r-TWT SP，每个r-TWT SP的时间段可以相同。周期T可以指示：第一广播TWT的相邻2个r-TWT SP之间的起始时间的间隔为T。
可以理解，至少一个终端#1也可以替换表述为一个广播TWT组，记为第一广播TWT组，也可以被称为是该第一广播TWT组内的终端。此外，第一广播TWT也可以参考上述“1.TWT”中的相关介绍，不再赘述。
第一广播TWT暂停是指：第一网络设备与至少一个终端#1不再通过第一广播TWT的信道进行数据的传输。例如，在第一网络设备与该广播TWT组内的终端已没有数据传输，或者第一网络设备与该广播TWT组内的终端之间的数据传输取消时，第一网络设备与至少一个终端#1的广播TWT会暂停。暂停的广播TWT可以为多个，任一个广播TWT具体可以是r-TWT。
可以理解，第一网络设备与第一网络设备的小区内的终端可以建立多个广播TWT，这多个广播TWT都可以暂停。方便理解，下文以第一广播TWT暂停为例进行介绍，其他广播TWT暂停可以参考理解，不再赘述。
暂停信息可以用于指示第一广播TWT暂停，具体可以通过第一广播TWT的标识或者通过第一广播TWT对应的比特位图指示第一广播TWT暂停，下面具体介绍。
方式A，通过第一广播TWT的标识指示暂停。此时，暂停信息可以包括如下至少一项：第一广播TWT的标识，以及第一广播TWT的暂停时间。
第一广播TWT的标识可以用于标识该第一广播TWT，如可以是r-TWT的ID。第一广播TWT的暂停时间可以包括：开始暂停的时间，以及结束暂停的时间，可选地，还可以包括第一广播TWT暂停的时长、第一广播TWT暂停恢复的时间等，不做限定。
在方式A中，暂停信息可承载在如下任一项中：增强的TWT信息帧、管理帧(management frame)以及公共行为帧(action frame)。此时，第一广播TWT的标识可以承载在这些帧的广播TWT标识域(broadcast TWT ID)中。第一广播TWT的暂停时间可以承载这些帧中的下一个TWT中。
可选地，这些帧还可以携带传输地址(transmitting address，TA)和接收地址(receiving address，RA)。传输地址为第一网络设备的小区的物理地址(media access control address，MAC)，每个网络设备都可以有一个网络标识，如MAC地址。接收地址为第二网络设备的小区的MAC地址。因此，第一网络设备可以根据第二网络设备的小区的MAC地址，将第一广播TWT的暂停信息发送给第二网络设备。
可以理解，一个r-TWT可以通过第一网络设备的小区的MAC地址和该r-TWT的ID来唯一标识，使得第二网络设备可以根据第一网络设备的小区的MAC地址和r-TWT的ID，确定具体是哪一个广播TWT被暂停，以避免第二网络设备对暂停的r-TWT进行误识别或者误处理。当然，在一个r-TWT的ID能够唯一标识该r-TWT的情况下，第二网络设备也可以仅根据该r-TWT的ID，确定是哪一个r-TWT被暂停。
情况1：增强的TWT信息帧。
如图5所示，增强的TWT信息帧可以是在图2a所示的TWT信息域的基础上进行的改进，例如将TWT信息域中的TWT流标识，要求应答以及下一个TWT要求的5个比特替换成一个广播TWT标识域。也即，第一广播TWT的标识可以通过这5个比特来承载。
所有TWT用于指示第一网络设备的所有r-TWT是否全部暂停，共占用1个比特。例如，所有TWT置1用于指示第一网络设备的r-TWT全部暂停，并且所有r-TWT的暂停时间相同，暂停时间可以通过下一个TWT进行指示，此时广播TWT标识域设置为预留字段。所有TWT置0用于指示第一网络设备的r-TWT没有全部暂停，此时第一网络设备可以通过广播TWT标识域指示具体暂停的r-TWT的标识。例如，暂停的r-TWT是第一广播TWT，此时第一网络设备可以通过广播TWT标识域指示暂停的r-TWT是第一广播TWT。
可以理解，所有TWT也可以设置为预留，在此基础上，第一网络设备可以直接通过广播TWT标识域来指示需要暂停的r-TWT。此时，下一个TWT子域大小和下一个TWT的含义与上述一致，在此不做赘述。
情况2：管理帧。
管理帧可以有多种帧结构，下面具体介绍。图6为本申请实施例提供的管理帧的帧结构示意图一，如图6所示，该管理帧可以包括：帧控制(frame control)、持续时长(duration)、接收地址、传输地址、TWT信息、下一个TWT、以及校验(frame check sequence，FCS)等。
其中，帧控制用于指示管理帧的基本信息，例如，帧类型等，共占用2个字节。
持续时长用于指示管理帧交互的时长，共占用2个字节。
接收地址可以占用6个字节，其含义与上述增强的TWT信息帧中的接收地址类似，不再赘述
传输地址可以占用4个字节，其含义与上述增强的TWT信息帧中的传输地址类似，不再赘述。
TWT信息用于指示广播TWT的暂停信息，共占用5个字节。例如，暂停的广播TWT的ID。
下一个TWT用于指示广播TWT的暂停时长信息，可以占用0、4、6或8个字节，也即占用0、32、48或64个比特。
校验用于校验管理帧的正确性，共占用4个字节。
TWT信息包括广播TWT标识域、下一个TWT域大小和所有TWT。
其中，广播TWT标识域、下一个TWT域大小和所有TWT的含义以及具体指示方式与图5类似，可以参考理解，在此不再赘述。
上述信元，如帧控制、持续时长、接收地址、传输地址、TWT信息、下一个TWT、以及校验占用的字节数仅为一种示例，其占用的字节数可以根据实际情况调整，不做具体限定。
图7为本申请实施例提供的管理帧的帧结构示意图二，如图7所示，该管理帧与图6所示的管理帧的区别在于，该管理帧中的TWT信息中的所有TWT设置为预留，此时第一网络设备可以通过广播TWT标识域指示需要暂停的广播TWT的标识。可以理解，图7中的其他字段的含义以及指示方式与图6类似，可以参考理解，在此不再赘述。
图8为本申请实施例提供的管理帧的帧结构示意图三，如图8所示，该管理帧包括：帧控制、持续时长、接收地址、传输地址、多个TWT信息、校验等。多个TWT信息可以为TWT信息1、TWT信息2、TWT信息N等。
每个TWT信息可以包括广播TWT标识域、下一个TWT域大小、所有TWT和下一个TWT。
相较于图6所示的管理帧，图8中的管理帧将下一个TWT放入每个TWT信息中，共占用一个1，5，7或9个字节。每个需要暂停的广播TWT都可以有一个独立的TWT信息，每个TWT信息中的下一个TWT都可以指示暂停的广播TWT的暂停时间。在所有TWT不为0的情况下，第一网络设备可以通过向第二网络设备发送一个该管理帧，就可以指示同时指示多个暂停的广播TWT和每个暂停的广播TWT对应的暂停时间，每个暂停的广播TWT的暂停时长可以不同。
若任意一个TWT信息中的所有TWT置为1，则用于指示第一网络设备的所有广播TWT暂停，此时每个暂停的广播TWT的暂停时间相同。在这种情况下，每个TWT信息中的广播TWT标识域可以设置为预留，用于后续扩展字段使用。
可以理解，图8中的其他字段的含义以及指示方式与图6类似，可以参考理解，在此不在赘述。
图9为本申请实施例提供的一种管理帧的帧结构示意图四，如图9所示，该管理帧与图8所示的管理帧的区别在于，管理帧中的每个TWT信息中的所有TWT设置为预留，也就是说，该管理帧不支持使用一个TWT信息指示所有的广播TWT暂停，此时第一网络设备可以通过每个广播TWT标识域指示需要暂停的广播TWT的标识。可以理解，图9中的其他字段的含义以及指示方式与图6类似，可以参考理解，在此不在赘述。
表1为公共行为帧的主体结构，可以包括范畴(category)、公共行为(public action)和r-TWT暂停信息元素。范畴和公共行为的含义可以参照现有技术的相关介绍，在此不做赘述。
表1
图10为本申请实施例提供的r-TWT暂停信息元素的结构示意图，如图10所示，r-TWT暂停信息元素包括元素标识(Element ID)、长度(length)、TWT信息、下一个TWT等。
元素标识用于指示r-TWT暂停信息元素的标识，共占用1个字节。

方式B，通过第一广播TWT对应的比特位图指示暂停。此时，暂停信息可以包括如下至少一项：第一比特位图，以及第一广播TWT的暂停时间，第一比特位图用于指示第一广播TWT暂停。第一比特位图包括第一网络设备的多个广播TWT对应的多个比特，多个比特中的第一比特在多个比特的位置用于指示第一广播TWT，第一比特的取值用于指示第一广播TWT暂停。
例如，第一比特位图包括32个比特，此时可以通过32个比特中的任意一个比特指示第一广播TWT，如通过第一比特位图的第六个比特的位置来指示第一广播TWT，将第一比特位图的第六个比特的位置记为比特6。在这种情况下，若比特6置1，用以指示第一广播TWT暂停；若比特6置0，用以指示第一广播TWT可以正常传输。在方式B中，暂停信息可以承载在管理帧中，因此，第一比特位图可以承载在该帧的广播TWT标识位图中。第一广播TWT的暂停时间可以承载在该帧的下一个TWT中。
图11为本申请实施例提供的管理帧的帧结构示意图五，如图11所示，广播TWT标识位图可以占用32个比特，每个比特位都可以对应指示一个广播TWT是否被暂停，多个比特的位置就可以同时指示多个暂停的广播TWT，从而可以节约开销。在这种情况下，多个暂停的广播TWT共享同一个下一个TWT，也就是说，多个暂停的广播TWT的暂停时间相同。
可以理解，图11中的其他字段的的含义以及具体指示方式与图6类似，可以参考理解，在此不再赘述。
图12为本申请实施例提供的管理帧的帧结构示意图六，如图12所示，该管理帧与图11所示的管理帧的区别在于，该管理帧中的TWT信息中的所有TWT设置为预留，此时第一网络设备可以通过广播TWT标识位图指示需要暂停的广播TWT的标识。
可以理解，图12中的其他字段的的含义以及指示方式与图6类似，可以参考理解，在此不再赘述。
可以理解，任意包含广播TWT标识域、广播TWT标识位图的帧，或可以指示所有r-TWT暂停的方法均可适用于本申请实施例，上述增强的TWT信息帧、管理帧以及公共行为帧仅为示例，在此不做限定。
S402：第一网络设备向第二网络设备发送暂停信息。第二网络设备接收来自第一网络设备的暂停信息。
其中，第二网络设备是与第一网络设备存在通信范围交叠的网络设备，或者说第二网络设备的小区与第一网络设备的小区存在通信范围的交叠。
第二网络设备的小区是指第二网络设备提供通信服务的区域，或者说第二网络设备的信号覆盖的一个物理区域，具体可以参考上述的相关介绍，不再赘述。第二网络设备的小区与第一网络设备的小区存在通信范围的交叠是指第一网络设备与第二网络设备提供通信服务的区域，或者信号覆盖的物理区域有重叠。
第一网络设备可以通过上述增强的信息帧、管理帧，以及公共行为帧，向第二网络设备发送暂停信息，第二网络设备根据接收到的上述帧确定具体是哪一个广播TWT被暂停以及暂停多久。例如，EHT AP1可以通过增强的信息帧向EHT AP2发送暂停信息，第二网络设备可以根据接收到的增强的信息帧帧确定暂停的广播TWT是第一广播TWT，以及第一广播TWT的暂停时间。
S403：第二网络设备根据暂停信息，向第二网络设备的小区内的至少一个终端发送第一指示信息。
其中，第一指示信息可以指示第二网络设备的小区内的至少一个终端(记为至少一个终端#2)在第一时间可以进行数据传输，可以理解，至少一个终端#2可以为第二网络设备的小区的至少部分终端，不做限定。方便理解，本申请实施例以至少一个终端#2为第二网络设备的小区内的所有终端。
第一时间是在第一广播TWT没有暂停的情况下，至少一个终端#2不能进行数据传输的时间点。也就是说，如果第一广播TWT没有暂停，则至少一个终端#2在对应的时间点(包括第一时间)都不能进行数据传输。为方便表述，将至少一个终端#2不能进行数据传输的时间点称为保护时间#1。例如，保护时间#1可以是至少一个终端#1通过信道竞争，与第一网络设备建立第一广播TWT的时间点。其中，第一时间具体可以是在每个第一广播TWT周期中，第一广播TWT的起始时间，如从r-TWT SP起始时间开始之后的一段时间。也就是说，保护时间#1可以是一个周期性的时间。对于至少一个终端#2而言，至少一个终端#2在每个周期的保护时间#1就不能进行数据传输，或者说需要保持静默状态，以避免对至少一个终端#1的信道竞争产生干扰。
本申请实施例中，至少一个终端#2保持静默状态的方式可以有两种，下面分别介绍。
方式11：第二网络设备直接指示至少一个终端#2保持静默状态。
由于第一网络设备在建立第一广播TWT的过程中需要广播信标帧，记为信标帧#1，具体实现可以参考上述“1.TWT”中的相关介绍，不再赘述。此时，第二网络设备也可以接收到该信标帧#1，从而可以根据信标帧#1，确定第一广播TWT的起始时间以及周期，进而确定每个周期的保护时间#1。在此基础上，第二网络设备可以指示至少一个终端#2需要在每个周期的保护时间#1保持静默状态。例如，第二网络设备可以广播第一指示信息，此时第一指示信息具体可以是信标帧，记为信标帧#2。与信标帧#1不同的是，该信标帧#2中携带有用于指示静默状态的静默元素。相应的，至少一个终端#2在接收到信标帧#2，就可以根据周期以及静默元素，确定在每个周期的保护时间#1需要保持静默状态。
方式12：第二网络设备通过建立第二广播TWT来指示至少一个终端#2保持静默状态。
根据上述方式11的相关介绍可知，在第二网络设备已经确定每个周期的保护时间#1的情况下，第二网络设备仍可以广播第一指示信息，此时第一指示信息具体可以是信标帧，记为信标帧#3。信标帧#3与信标帧#1类似，主要用于建立与第一广播TWT服务阶段的第二广播TWT，如，第一广播TWT与第二广播TWT的周期以及起始时间相同。至少一个终端#2在接收到信标帧#3，可以根据信标帧#3，请求第二网络设备将至少一个终端#2加入到第二广播TWT。但是，第二网络设备需要拒绝至少一个终端#2的请求，此时，对于被拒绝的至少一个终端#2而言，至少一个终端#2就需要在第二广播TWT的每个周期的起始开始后的一段时间保持静默状态，记为保护时间#2，以避免对第一广播TWT产生干扰。此时，由于第二广播TWT的每个周期的保护时间#2与第一广播TWT的每个周期的保护时间#1同步，因此，至少一个终端#2在第二广播TWT的每个周期的保护时间#2保持静默状态，也可以避免对第一广播TWT产生干扰。
可以理解，上述方式11和方式12也可结合实施，不做限定。
本申请实施例中，在第一广播TWT已经暂停的情况下，至少一个终端#2就不再需要在对应的保护时间#1保持静默状态，该保护时间#1也即为第一时间。也是就说，第一时间也可以理解为周期性的保护时间#1中的特定时间。此时，至少一个终端#2可以恢复在第一时间的数据传输，具体可通过如下多种方式恢复。
方式21：
第二网络设备通过方式11对第一广播TWT的信道接入进行保护，此时第二网络设备接收到来自第一网络设备的暂停信息后，可以向至少一个终端#2广播信标帧，记为信标帧#4。与信标帧#2不同的是，该信标帧#4可以不携带静默元素，用以指示至少一个终端#2不需要在第一时间保持静默状态，能进行数据的传输。此后，如果第一广播TWT将要恢复传输，则第二网络设备仍可以通过上述方式11的方式来指示至少一个终端#2保持静默状态，不再赘述。
方式22：
第二网络设备通过方式12对第一广播TWT的信道接入进行保护，此时第二网络设备接收到来自第一网络设备的暂停信息后，可以向至少一个终端#2广播信标帧，记为信标帧#5。与信标帧#3不同的是，该信标帧#5可以携带TWT元素。该TWT元素的TWT设置命令域(TWT setup command)可以为拒绝TWT(reject TWT)，用以指示至少一个终端#2需要将第二广播TWT取消，以使至少一个终端#2在第一时间不用需要保持静默，能进行数据的传输。此后，第二网络设备可以向至少一个终端#2发送第二指示信息，此时的第二指示信息可以是上述的信标帧#3，用以 指示第一广播TWT恢复后建立第三广播TWT，第三广播TWT与第一广播TWT服务阶段的时间段相同，第三广播TWT是不允许至少一个终端与第二网络设备建立广播TWT服务阶段的广播TWT。具体实现原理与建立第二广播TWT类似，可以参考上述的相关介绍，不再赘述。
方式23：
第二网络设备通过方式12对第一广播TWT的信道接入进行保护，此时第二网络设备接收到来自第一网络设备的暂停信息后，可以向至少一个终端#2发送广播帧，以指示第二广播TWT暂停。在这种情况下，第二网络设备通常不需要为第一广播TWT的恢复执行相关操作。
可以理解，广播帧可以为上述图6-图12的任一种结构，在此不做限定。此外，方式21-方式23也可以任意组合实施，不做限定。
方便理解，下面以至少一个终端#2中的第一终端为例介绍。
S404：第二网络设备的小区内的第一终端接收来自第二网络设备的第一指示信息。
第一终端可以从第二网络设备接收到信标帧或广播帧，也即第一指示信息，具体可以参考上述S403中的相关介绍，不再赘述。
S405：第一终端根据第一指示信息，进行数据传输。
第一终端根据可以根据上述方式21-方式23进行数据传输，可以参考理解，在此不做赘述。
综上，在第一网络设备的小区与第二网络设备的小区存在通信范围的交叠，导致第一网络设备的小区的通信会对第二网络设备的小区产生影响的情况下，如果第一网络设备的小区内的通信暂停，如该小区内的第一网络设备与至少一个终端的第一TWT暂停。此时，第一网络设备可以通过暂停信息，通知第二网络设备的小区，以便第二网络设备的小区可以根据该暂停信息，向第二网络设备的小区内的至少一个终端，如第二网络设备的小区内的第一终端，发送第一指示信息，以指示第一终端可以不需要保持静默，可以执行数据的传输，从而可以提高第二网络设备的小区的通信资源利用率。
