Description

参数处理方法及接入点设备、站点设备及存储介质 技术领域
本公开涉及移动通信技术领域，具体而言，本公开涉及一种参数处理方法及接入点设备、站点设备及存储介质。
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，会支持多连接通信。例如，在无线通信系统中的接入点(Access Point，AP)和站点(Station，STA)可以是多连接设备(Multi-Link Device，MLD)，MLD支持在同一时刻能够在多连接下同时发送和/或接收的功能。因此，AP MLD与STA MLD之间可以存在多个连接进行通信。
此外，为了提高频谱利用率及适应高密集通信环境，引入了空间复用(Spatial Reuse，SR)技术，然而，现有的SR机制仅支持单连接应用， 而不适用于多连接通信。

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1中所示，本公开实施例提供了一种参数处理方法，可选地，所述方法可应用于支持多连接的接入点设备(AP或AP MLD)，该方法可以包括以下步骤：
步骤101，发送目标无线帧；其中，所述目标无线帧中携带所述接入点设备的至少两条通信连接的空间复用SR参数信息；所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息。可选地，可以在一个所述通信连接中发送所述目标无线帧。
在无线局域网中，一个基本服务集(Basic Service Set，BSS)可以由AP以及与AP通信的一个或多个站点(Station，STA)构成。一个基本服务集可以通过其AP连接到分配系统(Distribution System，DS)，然后再接入到另一个基本服务集，构成扩展的服务集(Extended Service Set，ESS)。
在本公开实施例中，AP和STA可以支持多连接的设备，例如，可以被分别表示为AP MLD和non-AP MLD。为了便于描述，在下文中，主要 描述一个AP与一个STA在多连接下进行通信的示例，然而，本公开的示例实施例不限于此。
作为第一示例，参见图2，AP MLD可以表示支持多连接通信功能的接入点，non-AP MLD可以表示支持多连接通信功能的站点。参照图2，AP MLD可以工作在三个连接下，如图2所示的AP1、AP2和AP3，每个AP可以分别工作在连接1、连接2以及连接3；non-AP MLD也可以工作在三个连接下，如图2所示的STA1、STA2和STA3，STA1工作在连接1、STA2工作在连接2以及STA3工作在连接3。在图2的示例中，假设AP1与STA1通过对应的第一连接Link 1进行通信，类似地，AP2与STA2通过对应的第二连接Link 2进行通信，AP通过第三连接Link 3与STA3进行通信。此外，Link 1至Link 3可以分别是不同频率下的多个连接，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。可以理解的是，图2所示的通信场景仅是示例性的，本公开构思不限于此，例如，AP MLD可以连接到多个non-AP MLD，或者在每个连接下，AP可以与多个其他类型的站点进行通信。
在多连接的场景中，AP MLD向non-AP MLD发送目标无线帧，目标无线帧例如信标(Beacon)帧、探测响应(Probe Response)帧、多连接探测响应(ML Probe Response)帧等。例如AP MLD将SR参数信息携带在ML信息元素(Information Element)中，并将ML信息元素携带在目标无线帧中，并在所述通信连接(或通信链路)下发送目标无线帧至对应的站点。
其中，SR参数信息包括所述AP MLD支持的多个连接的空间复用相关的参数信息，所述参数信息用于所述AP MLD与站点在数据交互时进行空间复用。本公开实施例中，所述目标无线帧中携带有与所述接入点设备的至少两条通信连接的空间复用SR参数信息；也就是说，目标无线帧中包括多个连接的SR参数信息，AP MLD与STA MLD均工作在多连接场景下，通过目标无线帧携带每个连接的SR参数信息，以支持多连接场景 的进行空间复用。可选地，AP MLD可选择一个连接作为发送通道，将目标无线帧发送至STA MLD。
所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息，作为一个可选实施例，每条所述通信连接的站点对应的所述目标SR参数信息不同。也就是说，每个通信连接所对应的SR参数信息中存在不同的参数部分，即目标SR参数信息。通常情况下，AP MLD的每个连接下的AP被配置成分属于不同的基本服务集，作为第二示例，结合图3，BSS1包括AP1以及STA1，BSS2包括AP2以及STA2。而针对每个站点，其对应的不同的BSS，因此对应不同的目标SR参数信息。目标SR参数信息例如空间复用组基本服务集标识位图(SRG BSS Color Bitmap)，这样，在SR参数信息中，包括与每个站点分别对应的SRG BSS Color Bitmap。
可以理解的是，SR参数信息中还包括所有站点通用的SR参数信息(后续简称通用SR参数信息)，通用SR参数信息例如元素标识、元素标识扩展等。每个站点在接收到通用SR参数信息以及各自的目标SR参数信息，根据SR参数信息与AP MLD在数据交互时进行空间复用。
本公开实施例中，AP MLD发送目标无线帧，所述目标无线帧中携带所述接入点设备的至少两条通信连接的空间复用SR参数信息；所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息；基于所述目标SR参数信息，实现多连接通信场景下的空间复用，提升系统吞吐量。
作为一个可选实施例，所述目标SR参数信息包括：
空间复用组基本服务集标识位图SRG BSS Color Bitmap信息以及空间复用组部分基本服务集标识位图SRG Partial BSSID Bitmap信息中的至少一种。
针对每个站点，其对应的不同的BSS，因此对应不同的SRG BSS Color Bitmap以及SRG Partial BSSID Bitmap，这样，在SR参数信息中，包括与每个站点分别对应的SRG BSS Color Bitmap以及SRG Partial BSSID  Bitmap的至少一种，即分别指示每个连接下的不同SR参数信息，以实现多连接场景下的空间复用。更进一步地，由于从属于同一个APMLD的每个AP不属于同一个BSS，所以其所生成的BSScolor值或BSSID也不一样，也属于不同的SRGBSScolorbitmap或不同的SRGpartialBSSIDbitmap。
参见图4，本公开实施例还提供了一种参数处理方法，可选地，所述方法可应用于支持多连接的接入点设备(AP或AP MLD)，该方法可以包括以下步骤：
步骤401，确定与每个站点对应的所述目标无线帧。
AP MLD在发送目标无线帧之前，首先生成目标无线帧；AP MLD确定站点的通用SR参数信息以及每个AP MLD所关联的站点各自的目标SR参数信息，生成并发送目标无线帧。其中，APMLD在每个连接下可能关联多个站点。
所述目标无线帧中携带所述接入点设备的至少两条通信连接的空间复用SR参数信息；所述SR参数信息中包括与每条所述通信连接的所述站点对应的目标SR参数信息。
目标无线帧中的SR参数信息中包括通用SR参数信息以及目标SR参数信息，通用SR参数信息例如元素标识、元素标识扩展等。每个站点在接收到通用SR参数信息以及各自的目标SR参数信息，根据SR参数信息与AP MLD在数据交互时进行空间复用。此外，在接收SR参数信息之前，站点可通过信令交互获知SRG BSS color信息或SRG Partial BSSID等信息。
步骤402，发送所述目标无线帧。
可选地，可以在一个所述通信连接中发送所述目标无线帧。
在一个可选实施例中，所述目标无线帧包括多连接ML信息元素；
所述ML信息元素包括多连接控制Multi-Link Control信息、站点配置per-STA profile信息以及连接信息Link info中的至少一种。
其中，除了Multi-Link Control信息、per-STA profile信息以及Link info，ML信息元素中还可包括其他信息；作为第三示例，其他信息以及各信息的字节数目例如表1中的元素标识、长度、元素标识扩展以及通用信息所 示：
表1：

此外，AP在每个连接下携带SR参数信息，具体为包含在ML信息元素的per-STA profile中，per-STA profile信息的格式如表2所示：
表2：
Figure PCTCN2021100662-appb-000002
在表2中，STA profile域中携带SR参数信息。
可以理解的是，除了表1中公开的信息内容，SR参数信息还包括可 以提供站点在空间复用操作中所需的其他信息，例如，元素标识(Element ID)、长度(Length)、空间复用控制(SR Control)、空间复用组OBSS PD最小发射功率偏置值(SRG OBSS PDMin Offset)、空间复用组OBSS PD最大发射功率偏置值(SRG OBSS PD Max Offset)，以及前述SRG BSS Color Bitmap、SRG Partial BSSID Bitmap等，在此不在赘述。
在一个可选实施例中，所述ML信息元素中还包括所述SR指示信息，所述SR指示信息指示所述目标无线帧中是否存在所述SR参数信息；也即SR指示信息指示空间复用为MLD级；所述SR指示信息携带在所述Multi-Link Control信息中或STA控制STA Control信息中。
作为第四示例，Multi-Link Control信息格式如表3所示，若所述SR指示信息携带在所述Multi-Link Control信息中，例如携带在Reserved域中。

若所述SR指示信息携带在所述per-STA profile信息中，作为第五示例，per-STA profile信息格式如表4所示，其中，STA Control域中包括的字节数目为6的Reserved域中，可在此处携带SR指示信息。

本公开实施例中，AP MLD发送目标无线帧，所述目标无线帧中携带所述接入点设备的至少两条通信连接的空间复用SR参数信息；所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息；基于所述目标SR参数信息，实现多连接通信场景下的空间复用，提升系统吞吐量。
参见图5，本公开实施例还提供了一种参数处理方法，应用于站点STA，STA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，所述方法包括：
步骤501，接收目标无线帧；其中，所述目标无线帧中携带接入点设备的至少两条通信连接的空间复用SR参数信息；所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息。
在无线局域网中，一个BSS可以由AP以及与AP通信的一个或多个STA构成。一个BSS可以通过其AP连接到DS，然后再接入到另一个基BSS，构成扩展的服务集ESS。
在本公开实施例中，AP和STA可以支持多连接的设备，例如，可以被分别表示为AP MLD和non-AP MLD。为了便于描述，在下文中，主要描述一个AP与一个STA在多连接下进行通信的示例，然而，本公开的示例实施例不限于此。
作为第一示例，参见图2，AP MLD可以表示支持多连接通信功能的接入点，non-AP MLD可以表示支持多连接通信功能的站点。参照图2，AP MLD可以工作在三个连接下，如图2所示的AP1、AP2和AP3，每个 AP可以分别工作在连接1、连接2以及连接3；non-AP MLD也可以工作在三个连接下，如图2所示的STA1、STA2和STA3，STA1工作在连接1、STA2工作在连接2以及STA3工作在连接3。在图2的示例中，假设AP1与STA1通过对应的第一连接Link 1进行通信，类似地，AP2与STA2通过对应的第二连接Link 2进行通信，AP通过第三连接Link 3与STA3进行通信。此外，Link 1至Link 3可以分别是不同频率下的多个连接，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。可以理解的是，图2所示的通信场景仅是示例性的，本公开构思不限于此，例如，AP MLD可以连接到多个non-AP MLD，或者在每个连接下，AP可以与多个其他类型的站点进行通信。
在多连接的场景中，non-AP MLD接收AP MLD发送的目标无线帧，目标无线帧例如Beacon帧、Probe Response帧、ML Probe Response帧等。例如AP MLD将SR参数信息携带在MLInformation Element中，并将ML信息元素携带在目标无线帧中，并在所述通信连接(或通信链路)下发送目标无线帧至对应的STA，则STA在接收到目标无线帧之后，从目标无线帧中获取SR参数信息。
其中，SR参数信息包括所述AP MLD支持的多个连接的空间复用相关的参数信息，所述参数信息用于所述AP MLD与站点在数据交互时进行空间复用。本公开实施例中，所述目标无线帧中携带有与所述接入点设备的至少两条通信连接的空间复用SR参数信息；也就是说，目标无线帧中包括多个连接的SR参数信息，AP MLD与STA MLD均工作在多连接场景下，通过目标无线帧携带每个连接的SR参数信息，以支持多连接场景的进行空间复用。可选地，AP MLD可选择一个连接作为发送通道，将目标无线帧发送至STA MLD。
所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息，作为一个可选实施例，每条所述通信连接的站点对应的所述目标SR参数信息不同。也就是说，每个通信连接所对应的SR参数信息中 存在不同的参数部分，即目标SR参数信息。通常情况下，AP MLD的每个连接下的AP被配置成分属于不同的基本服务集，而针对每个站点，其对应的不同的BSS，因此对应不同的目标SR参数信息。目标SR参数信息例如SRG BSS Color Bitmap，这样，在SR参数信息中，包括与每个站点分别对应的SRG BSS Color Bitmap。
可以理解的是，SR参数信息中还包括通用SR参数信息，通用SR参数信息例如元素标识、元素标识扩展等。每个站点在接收到通用SR参数信息以及各自的目标SR参数信息，根据SR参数信息与AP MLD在数据交互时进行空间复用。
本公开实施例中，站点接收目标无线帧，所述目标无线帧中携带接入点设备的至少两条通信连接的空间复用SR参数信息；所述SR参数信息中包括与每条所述通信连接的站点对应的目标SR参数信息；基于所述目标SR参数信息，实现多连接通信场景下的空间复用，提升系统吞吐量。

空间复用组基本服务集标识位图SRG BSS Color Bitmap信息以及空间复用组部分基本服务集标识位图SRG Partial BSSID Bitmap信息中的至少一种。
针对每个站点，其对应的不同的BSS，因此对应不同的SRG BSS Color Bitmap以及SRG Partial BSSID Bitmap，这样，在SR参数信息中，包括与每个站点分别对应的SRG BSS Color Bitmap以及SRG Partial BSSID Bitmap的至少一种，即分别指示每个连接下的不同SR参数信息，以实现多连接场景下的空间复用。更进一步地，由于从属于同一个APMLD的每个AP不属于同一个BSS，所以其所生成的BSScolor值或BSSID也不一样，也属于不同的SRGBSScolorbitmap或不同的SRGpartialBSSIDbitmap。
作为一个可选实施例，所述目标无线帧包括多连接ML信息元素；
所述ML信息元素包括多连接控制Multi-Link Control信息、站点配置per-STA profile信息以及连接信息Link info中的至少一种。
其中，除了Multi-Link Control信息、per-STA profile信息以及Link info， ML信息元素中还可包括其他信息；参见前述第三示例，其他信息以及各信息的字节数目例如前述表1中的元素标识、长度、元素标识扩展以及通用信息。除了表1中公开的信息内容，SR参数信息还包括可以提供站点在空间复用操作中所需的其他信息，例如Element ID、Length、SR Control、SRG OBSS PDMin Offset、SRG OBSS PD Max Offset以及前述SRG BSS Color Bitmap、SRG Partial BSSID Bitmap等，在此不在赘述。
此外，AP在每个连接下携带SR参数信息，具体为包含在ML信息元素的per-STA profile中，per-STA profile信息的格式如前述表2所示，在此不在赘述。
作为一个可选实施例，所述ML信息元素中还包括所述SR指示信息，所述SR指示信息指示所述目标无线帧中是否存在所述SR参数信息；也即SR指示信息指示空间复用为MLD级；所述SR指示信息携带在所述Multi-Link Control信息中或per-STA profile信息中。
参见前述第四示例，Multi-Link Control信息格式如前述表3所示，若所述SR指示信息携带在所述Multi-Link Control信息中，例如携带在Reserved域中。若所述SR指示信息携带在所述per-STA profile信息中，参见前述第五示例，per-STA profile信息格式如前述表4所示，其中，per-STA profile域中包括的字节数目可变，可在此处携带SR指示信息。
作为一个可选实施例，所述目标SR参数信息携带在所述Link info中，即每个站点各自的目标SR参数信息，携带在Presence Bitmap域中。
作为一个可选实施例，所述目标SR参数信息携带在所述Link info中，即每个站点各自的目标SR参数信息，携带在Presence Bitmap域中。参见前述第六示例，如前述表5所示，Presence Bitmap格式中，可在Reserved域中携带目标SR参数信息。
作为一个可选实施例，所述目标无线帧包括信标Beacon帧、探测响应Probe Response帧、多连接探测响应ML Probe Response帧、关联请求Association Response帧以及重关联请求Reassociation Response帧中的至少一种。可以理解的是，除此之外，目标无线帧还可能包括其他形式，本 公开实施例在此不做具体限定。
