背景技术
随着移动通信技术的迅速发展，无线保真(Wireless Fidelity，Wi-Fi)技术在传输速率以及吞吐量等方面已经取得了巨大的进步。目前，Wi-Fi技术所研究的内容例如320MHz的带宽传输、多个频段的聚合及协同等，其主要的应用场景例如视频传输、增强现实(Augmented Reality，AR)、虚拟现实(Virtual Reality，VR)等。
具体地，多个频段的聚合及协同是指设备之间同时在2.4GHz、5.8GHz、6GHz及其他频段下进行通信，对于设备之间同时在多个频段下通信的场景，还需要定义新的介质访问控制(Media Access Control，MAC)机制来进行管理。此外，多频段的聚合及协同有望能够支持低时延传输。
目前，多频段的聚合及协同技术中，将支持的最大带宽为320MHz(160MHz+160MHz)，此外，还可能会支持240MHz(160MHz+80MHz)及现有标准支持的其它带宽。
在目前所研究的Wi-Fi技术中，在增强多连接单通(enhanced Multi-Link Single Radio)eMLSR模式下支持多连接的非接入点设备(Non-Access Point Multi-Link Device，Non-AP MLD)可以在多个处于激活状态的连接(link)下进行帧听，并且在一个处于激活状态的连接下完成帧交互后在各个处于激活状态的连接下切换回帧听状态。其中，Non-AP MLD可能在每个处于激活状态的连接下接收到帧，如感知到信道繁忙，则会设置自身的网络分配矢量(Network Allocation Vector，NAV)定时器 以标识信道繁忙，但是对于其他处于激活状态的连接的NAV定时器该如何设置尚无定论。

本公开实施例提供了一种网络分配矢量NAV定时器的处理方法及相关装置，用以在eMLSR模式下对NAV定时器进行处理。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1中所示，本公开实施例提供了一种网络分配矢量NAV定时器的处理方法，可选地，该方法可应用于支持多连接的非接入点设备Non-AP MLD，该方法可以包括以下步骤：
步骤101，在增强多连接单通eMLSR模式下，确定Non-AP MLD的第一通信连接的连接类型。
其中，在eMLSR模式下，Non-AP MLD可以在多个处于激活状态的通信连接(link)下进行帧听，并且在一个处于激活状态的通信连接下完成帧交互后在各个处于激活状态的通信连接下切换回帧听状态。
其中，Non-AP MLD可能在每个处于激活状态的通信连接下接收到无线帧，如感知到信道繁忙，则会设置自身的网络分配矢量(Network Allocation Vector，NAV)定时器以标识信道繁忙。其中，NAV定时器用于实现虚拟载波监听，当NAV定时器不为0时，表示信道繁忙，当NAV定时器为0时，表示信道空闲。
本公开实施例中，Non-AP MLD可以为站点(Station，STA)设备，上述通信连接可以为支持多连接的接入点设备AP MLD和Non-AP MLD之间的通信连接。每个通信连接可以分别是不同频率下的连接，例如，2.4GHz、5GHz、6GHz下的连接，或2.4GHz下的几个相同或不同带宽的连接。此外，在每个连接下可以存在多个信道。
可选地，上述连接类型包括支持同时发送和接收(Simultaneous Transmit and Receive，STR)连接或支持非同时接收和发送(Non-Simultaneous Transmit and Receive,NSTR)连接。即Non-AP MLD对应的处于激活状态的通信连接可以全部为STR连接，也可以全部为NSTR连接。
当Non-AP MLD对应的处于激活状态的通信连接全部为STR连接时，Non-AP MLD处于STR模式，即Non-AP MLD可通过一个处于激活状态的STR连接接收AP MLD发送的无线帧，并同时通过另一个处于激活状态的STR连接向AP MLD发送无线帧。当Non-AP MLD对应的处于激活状态的通信连接全部为NSTR连接时，Non-AP MLD处于NSTR模式，即Non-AP MLD在某一时刻只能通过一个处于激活状态的NSTR连接接收AP MLD发送的无线帧或者向AP MLD发送无线帧。
可选地，上述Non-AP MLD包括处于激活状态的第一通信连接以及第二通信连接，上述第二通信连接包括接收到目标无线帧的NSTR连接或进行帧交互的STR连接。
当Non-AP MLD对应的处于激活状态的通信连接的连接类型均为NSTR连接时，上述第二通信连接为接收到目标无线帧的NSTR连接。上述第一通信连接为Non-AP MLD对应的处于激活状态的通信连接中，除上述的第二通信连接外的其他通信连接。
其中，上述目标无线帧为AP MLD发送的初始控制(initial control)帧或者非初始控制帧(除初始控制帧外的其他无线帧)。即上述第二通信连接为接收到AP MLD发送的初始控制帧的NSTR连接，或者为接收到AP MLD发送的非初始控制帧的NSTR连接。
可选地，上述初始控制帧可以为多用户请求发送(Multi-user Request to Send，MU-RTS)触发帧或者缓存状态报告轮询(Buffer Status Report Poll，BSRP)触发帧。
当Non-AP MLD对应的处于激活状态的通信连接的连接类型均为STR连接时，由于Non-AP MLD可以同时在多个通信连接下接收到不同AP MLD发送的初始控制帧，因此上述第二通信为接收到初始控制帧后与对应的AP MLD进行帧交互的STR连接。上述第一通信连接为Non-AP MLD对应的处于激活状态的通信连接中，除上述的第二通信连接外的其他通信连接。
步骤102，根据连接类型，对第一通信连接的NAV定时器进行处理。
在确定Non-AP MLD对应的处于激活状态中的第一通信连接和第二 通信连接，且确定出第一通信连接的连接类型之后，可根据第一通信连接的连接类型，对第一通信连接的NAV定时器进行处理。
在一个可选实施例中，第一通信连接的连接类型为STR连接；根据第一通信连接的连接类型，对第一通信连接的NAV定时器进行处理，包括：
在第二通信连接为进行帧交互的STR连接的情况下，在帧交互过程中对第一通信连接的NAV定时器进行处理。
其中，Non-AP MLD对应的各处于激活状态的通信连接分别对应于独立的NAV定时器，在Non-AP MLD运行过程中，每一NAV定时器通过对应的剩余时长来标识信道是否繁忙以及信道在繁忙情况下的占用时间。
在Non-AP MLD通过第二通信连接接收到AP MLD发送的初始控制帧，且确定与该AP MLD进行帧交互的情况下，需要在帧交互过程中对第一通信连接的NAV定时器进行处理。并且在帧交互过程中(也即对第一通信连接的NAV定时器进行处理的过程中)第一通信连接的NAV定时器处于暂停状态，以在该过程中完成对NAV定时器的处理。
即在Non-AP MLD通过任一处于激活状态的STR连接接收到AP MLD发送的初始控制帧，且确定通过该STR连接与该AP MLD进行帧交互的情况下，在帧交互过程中对其他处于激活状态的STR连接的NAV定时器进行处理。
在一个可选实施例中，在帧交互过程中对第一通信连接的NAV定时器进行处理，包括：
确定第一通信连接的NAV定时器的剩余时长；
确定帧交互时长；
根据帧交互时长和剩余时长，在帧交互过程中对第一通信连接的NAV定时器进行处理。
即在帧交互过程中对其他处于激活状态的STR连接的NAV定时器进行处理时，对于其他处于激活状态的STR连接中的任一STR连接，可确定该STR连接的NAV定时器的剩余时长。该STR连接的NAV定时器的剩余时长可表示该STR连接对应的信道是否繁忙，且在繁忙情况下的占 用时间。进一步确定帧交互时长，以根据帧交互时长和剩余时长，在帧交互过程中对该STR连接的NAV定时器进行处理。
在一些可选实施例中，根据帧交互时长和剩余时长，在帧交互过程中对第一通信连接的NAV定时器进行处理，包括：
在第一通信连接的NAV定时器的剩余时长大于帧交互时长的情况下，在帧交互过程中将第一通信连接的NAV定时器的剩余时长更新为第一时长；其中，第一时长为第一通信连接的NAV定时器的剩余时长与帧交互时长的时长之差；
在第一通信连接的NAV定时器的剩余时长小于或者等于帧交互时长的情况下，在帧交互过程中将第一通信连接的NAV定时器的剩余时长更新为0。
进一步地，在通过第二通信连接与对应的Non-AP MLD完成帧交互后，可在各处于激活状态的通信连接(第一通信连接和第二通信连接)下切换至帧听状态。
即在帧交互过程中对其他处于激活状态的STR连接的NAV定时器进行处理时，对于其他处于激活状态的STR连接中的任一STR连接的NAV定时器，可先确定该NAV定时器的剩余时长。
进一步地，若该NAV定时器的剩余时长大于帧交互时长，则在帧交互过程中将该NAV定时器置于暂停状态，并在帧交互过程中将该NAV定时器的剩余时长更新为该NAV定时器的剩余时长与帧交互时长之积(第一时长)。在完成帧交互过程之后，在该NAV定时器对应的STR连接下切换至帧听状态，此时该NAV定时器启动并基于更新后的剩余时长表示在对应的信道在繁忙情况下的占用时间。
若该NAV定时器的剩余时长小于或者等于帧交互时长，则在帧交互过程中将该NAV定时器置于暂停状态，并在帧交互过程中将该NAV定时器的剩余时长更新为0。在完成帧交互过程之后，在该NAV定时器对应的STR连接下切换至帧听状态，由于该NAV定时器的剩余时长为0，因此可表示对应的信道为空闲状态。
在一个可选实施例中，第一通信连接的连接类型为NSTR连接；根据 第一通信连接的连接类型，对第一通信连接的NAV定时器进行处理，包括：
在通过第二通信连接接收到的目标无线帧为初始控制帧的情况下，不对第一通信连接的NAV定时器进行更新；
在通过第二通信连接接收到的目标无线帧为非初始控制帧的情况下，确定非初始控制帧对应的处理时长，将第一通信连接的NAV定时器的剩余时长更新为处理时长。
即在Non-AP MLD通过任一处于激活状态的NSTR连接接收到AP MLD发送的初始控制帧的情况下，无需对其他处于激活状态的NSTR连接的NAV定时器进行处理。
在Non-AP MLD通过任一处于激活状态的NSTR连接接收到AP MLD发送的非初始控制帧(其他帧)的情况下，可先确定非初始控制帧对应的处理时长。
进一步地，对于其他处于激活状态的NSTR连接中的任一NSTR连接的NAV定时器，可直接将该NAV定时器的剩余时长更新为非初始控制帧对应的处理时长，此时该NAV定时器基于更新后的剩余时长表示在对应的信道在繁忙情况下的占用时间。
在一个可选实施例中，Non-AP MLD设备需要等待与处理时长相同的时间，并在之后在各处于激活状态的通信连接(第一通信连接和第二通信连接)下切换至帧听状态。
在一个可选实施例中，确定非初始控制帧的处理时长，包括以下至少一项：
根据非初始控制帧的媒体接入控制(Medium Access Control，MAC)帧头中duration字段对应的时间长度，确定处理时长；
根据非初始控制帧的物理层PHY(Physical)帧头中length字段对应的时间长度，确定处理时长。
作为一示例，在Non-AP MLD通过任一处于激活状态的NSTR连接接收到AP MLD发送的非初始控制帧的情况下，可将该非初始控制帧的 MAC帧头中duration字段对应的时间长度确定为该非初始控制帧的处理时长。
作为一示例，在Non-AP MLD通过任一处于激活状态的NSTR连接接收到AP MLD发送的非初始控制帧的情况下，可将该非初始控制帧的物理层PHY帧头中length字段对应的时间长度确定为该非初始控制帧的处理时长。
可以理解的是，在Non-AP MLD处于STR模式时，在通过任一处于激活状态的STR连接进行帧交互且对其他处于激活状态的STR连接的NAV定时器进行更新后，Non-AP MLD可在各处于激活状态的STR连接下进行帧听。并在基于任一处于激活状态的STR连接接收到AP MLD发送的初始控制帧，且确定与之进行帧交互后，在帧交互过程中重新基于上述实现方式对其他处于激活状态的STR连接的NAV定时器进行处理。
在Non-AP MLD处于NSTR模式时，通过任一处于激活状态的NSTR连接接收到非初始控制帧，并等待该非处是控制帧的处理时长之后，重新在各激活状态的NSTR连接下进行侦听。并通过任一处于激活状态的NSTR连接接收到初始控制帧后不对其他处于激活状态的NSTR连接的NAV定时器进行更新，通过任一处于激活状态的NSTR连接接收到非初始控制帧后，重新基于该初始控制帧的处理时长更新其他处于激活状态的NSTR连接的NAV定时器并等待对应的处理时长。
本公开实施例中，在eMLSR模式下，Non-AP MLD通过任一处于激活状态的NSTR连接接收到目标无线帧的情况下可对其他处于激活状态的NSTR的NAV定时器的进行更新，或者通过任一处于激活状态的STR连接进行帧交互的情况下可对其他处于激活状态的STR连接的NAV定时器的进行处理，适用性高。
基于与本公开实施例所提供的方法相同的原理，本公开实施例还提供了一种支持多连接的非接入点设备Non-AP MLD，Non-AP MLD可以是指向用户提供语音和/或数据连通性的设备、具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。

可选地，本公开实施例中，上述处理模块22，用于在等待上述处理时长之后，在上述第一通信连接和上述第二通信连接下切换至侦听状态。
