本公开实施例提供了一种通信方法及装置、电子设备及存储介质,用以提供一种在多连接场景下,指示BSS参数发生变化的方式。
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通信方法,可选地,所述方法可应用于支持多连接的站点设备Non-AP MLD,该方法可以包括以下步骤:
步骤101,发送第一无线帧;其中,所述第一无线帧中携带基本服务集BSS变更指示信息;所述BSS变更指示信息包括与接入点设备AP MLD之间的BSS变更参数,所述BSS变更参数包括变更序列元素和/或变更计数值。
本公开实施例中,AP和STA可以为支持多连接的设备,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可以工作在三个通信连接(Link)下,如图2所示的AP1、AP2和AP3,每个AP可以分别工作在(通信)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。
当AP MLD的系统信息发生更新时,non-AP MLD需要获知更新状况,因此,non-AP MLD向AP MLD发送第一无线帧,在所述第一无线帧中携带基本服务集BSS变更指示信息,以获取一个或多个通信连接下的系统信息更新内容。可选地,non-AP MLD可以在与AP MLD的一个通信连接中发送第一无线帧,以节省信令资源。
可选地,所述BSS变更指示信息包括:与所述AP MLD之间一个通信连接或至少两个通信连接的BSS变更参数,所述BSS变更参数包括变更序列元素(Change Sequence element)以及变更计数值(Change Count)中的至少一种。可选地,当AP MLD从接收到来自non-AP MLD且包含变更序列元素的第一无线帧时,AP MLD将接收到的更改序列字段值与其当前最近维持(最近即与当前时间最接近)的更改序列字段值进行比较,若比较结果不相等,则AP MLD发送所述变更序列元素以及其他需要由non-AP MLD更新的元素给non-AP MLD,使得non-AP MLD根据此次更新执行相应操作。
作为第一示例,Change Sequence element格式如以下表1所示:
表1:
Figure PCTCN2021122934-appb-000001
表1中,Change Sequence element包括3个子元素,分别占据1个字节。
Change Count记载了APMLD的BSS参数变更计数,通常情况下,每个AP的Change Count初始化值为0,并应在该AP的操作参数发生关键更新时递增(modulo运算,模256),例如,AP的操作参数发生关键更新,Change Count为N(N为自然数),将N递增为N+1,则将N+1与256取模值,得到更新后的Change Count。
可选地,第一无线帧可以是ML Probe Request(多连接探测请求帧)。
这样,non-AP MLD在一个连接下发送第一无线帧以请求AP MLD系统信息更新情况;其中,non-AP MLD可以不在每一个连接均下发送与该连接对应的BSS变更参数,以节省信令消息;例如,在一个连接下发送所有连接的BSS变更参数。
本公开实施例中,non-AP MLD发送第一无线帧,以请求AP MLD的系统信息更新内容;第一无线帧中携带BSS变更指示信息,所述BSS变更指示信息包括non-AP MLD与AP MLD之间一个或多个通信连接的BSS变更参数,以提供一种在多连接场景下,指示BSS参数发生变化的方式。
在一个可选实施例中,所述BSS变更指示信息还包括:与每个所述BSS变更参数分别对应的目标通信连接的连接标识信息。
其中,连接标识信息即Link ID,Link ID标识变更序列元素和/或变更计数值发生变化的连接,与之一一对应。BSS变更指示信息中包括多个通信连接的BSS变更参数的情况下,可以为每个BSS变更参数添加对应的目标通信连接;作为第二示例,BSS变更指示信息格式如以下表2所示:
表2:
Figure PCTCN2021122934-appb-000002
其中,每个Link ID后包括与其对应的Change Sequence element和/或Change Count。
在一个可选实施例中,所述发送第一无线帧之前,所述方法还包括:
接收第二无线帧;
获取所述第二无线帧中的第一多连接ML元素中的所述连接标识信息。
可选地,第二无线帧可以是信标(beacon)帧,non-AP MLD在每个通信连接下分别接收第二无线帧,并获取AP MLD在第二无线帧中携带的第一ML元素中的连接标识信息。
在一个可选实施例中,所述BSS变更指示信息还包括:BSS参数变更计数呈现指示信息;所述BSS参数变更计数呈现指示信息(BSS Parameter Change Count Present)用于指示是否包含所述BSS变更指示信息,即该第一无线帧中是否包括BSS变更指示信息,比如,在第一无线帧的某个元素中新增一指示域,在其中携带BSS Parameter Change Count Present。例如,当non-AP MLD在第二无线帧中监听到Change Count,表 明AP MLD的系统信息发生更新,则non-AP MLD将BSS Parameter Change Count Present的值设置为1,以指示第一无线帧用于请求获取AP MLD所更新的系统信息。此外,non-AP MLD还将当前的Change Count(记为M)增加1,将增加1后的Change Count(记为M+1)携带在第一无线帧中发送给AP MLD,便于AP MLD将M+1更新为当前的Change Count。
在一个可选实施例中,所述BSS变更指示信息还包括:多连接设备标识MLD ID;
其中,所述MLD ID包括所述Non-AP MLD的介质访问控制层MAC地址,即在该BSS变更指示信息中携带请求AP MLD的系统信息更新内容的Non-AP MLD的标识;将介质访问控制层地址(Media Access Control Address,MAC),作为MLD ID。
作为第三示例,BSS变更指示信息格式如以下表3所示:
表3:
Figure PCTCN2021122934-appb-000003
表3中,该MLD ID下包括多个Link,每个Link的Link ID后包括与其对应的Change Sequence element和/或Change Count。
在一个可选实施例中,所述发送第一无线帧,包括:
在一个所述通信连接中,发送所述第一无线帧。
non-AP MLD在一个连接下发送第一无线帧来请求AP MLD发送所有通信连接对应的BSS变更参数,以节省信令消息,降低冲突发生的可能 性;同时,减少信令消息的发送,可降低电量消耗。
在一个可选实施例中,所述发送第一无线帧,包括:
在所述Non-AP MLD处于节能状态下,发送所述第一无线帧。
节能状态即省电(Power Save)状态;处于省电状态的Non-AP MLD,可在不苏醒的状态下发送第一无线帧,即Non-AP MLD在发送第一无线帧时,无需由省电状态切换至苏醒状态,以进一步节省电量。
参见图3,本公开实施例还提供了一种通信方法,可选地,所述方法可应用于Non-AP MLD,该方法可以包括以下步骤:
步骤301,发送第一无线帧;所述第一无线帧包括多连接探测请求帧ML Probe Request;
其中,所述ML Probe Request携带基本服务集BSS变更指示信息;所述BSS变更指示信息包括与接入点设备AP MLD之间的BSS变更参数,所述BSS变更参数包括变更序列元素和/或变更计数值;
所述BSS变更指示信息携带在所述ML Probe Request的第二ML信息元素中,所述第二ML信息元素的类型为Probe Request。
其中,当AP MLD的系统信息发生更新时,non-AP MLD需要获知更新状况,因此,non-AP MLD向AP MLD发送ML Probe Request,在所述ML Probe Request中携带基本服务集BSS变更指示信息,以获取一个或多个通信连接下的系统信息更新内容。可选地,non-AP MLD可以在与AP MLD的一个通信连接中发送ML Probe Request,以节省信令资源。
可选地,所述BSS变更指示信息包括:与所述AP MLD之间一个通信连接或至少两个通信连接的BSS变更参数,所述BSS变更参数包括Change Sequence element以及Change Count中的至少一种。
具体地,所述ML Probe Request包括第二ML信息元素中,所述第二ML信息元素的类型为Probe Request。作为第四示例,第二ML信息元素的类型子字段编码如表4所示,其类型为Probe Request。
表4:

进一步的,第二ML信息元素的格式如表5所示,其包括元素标识、长度、元素标识扩展、多连接控制以及通用信息等:

本公开实施例中,AP和STA可以为支持多连接的设备,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可以工作在三个通信连接(Link)下,如图2所示的AP1、AP2和AP3,每个AP可以分别工作在(通信)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。
当AP MLD的系统信息发生更新时,non-AP MLD需要获知更新状况,因此,non-AP MLD向AP MLD发送第一无线帧,在所述第一无线帧中携带基本服务集BSS变更指示信息,以获取一个或多个通信连接下的系统信息更新内容。可选地,non-AP MLD可以在与AP MLD的一个通信连接中发送第一无线帧,以节省信令资源。
可选地,所述BSS变更指示信息包括:与所述AP MLD之间一个通信连接或至少两个通信连接的BSS变更参数,所述BSS变更参数包括变更序列元素(Change Sequence element)以及变更计数值(Change Count)中的至少一种。
Change Count记载了APMLD的BSS参数变更计数,通常情况下,每个AP的Change Count初始值化值为0,并应在该AP的操作参数发生关键更新时递增(模256)。
可选地,第一无线帧可以是ML Probe Request(多连接探测请求帧)。
这样,non-AP MLD在一个连接下发送第一无线帧以请求AP MLD系统信息更新情况;其中,non-AP MLD可以不在每一个连接均下发送与该连接对应的BSS变更参数,以节省信令消息;例如,在一个连接下发送 所有连接的BSS变更参数。
AP MLD接收到第一无线帧后,将BSS变更参数中的更改序列字段值与其当前最近保存的更改序列字段值进行比较,若比较结果不相等,则AP MLD发送所述变更序列元素以及其他需要由non-AP MLD更新的元素给non-AP MLD,使得non-AP MLD根据此次更新执行相应操作。
在一个可选实施例中,所述接收第一无线帧之前,所述方法还包括:
发送第二无线帧,在所述第二无线帧中的第一多连接ML元素中携带所述连接标识信息。
可选地,第二无线帧可以是beacon帧,AP MLD在每个通信连接下分别向non-AP MLD发送第二无线帧,在其中携带第一ML元素中的连接标识信息。

当AP MLD的系统信息发生更新时,non-AP MLD需要获知更新状况,因此,non-AP MLD向AP MLD发送第一无线帧,在所述第一无线帧中携带基本服务集BSS变更指示信息,以获取一个或多个通信连接下的系统信息更新内容。可选地,non-AP MLD可以在与AP MLD的一个通信连接中发送第一无线帧,以节省信令资源。
可选地,所述BSS变更指示信息包括:与所述AP MLD之间一个通信连接或至少两个通信连接的BSS变更参数,所述BSS变更参数包括变更序列元素(Change Sequence element)以及变更计数值(Change Count)中的至少一种。可选地,当AP MLD从接收到来自non-AP MLD且包含变更序列元素的第一无线帧时,AP MLD将接收到的更改序列字段值与其当前最近保存的更改序列字段值进行比较,若比较结果不相等,则AP MLD发送所述变更序列元素以及其他需要由non-AP MLD更新的元素给non-AP MLD,使得non-AP MLD根据此次更新执行相应操作。作为第一 示例,Change Sequence element格式如以下表1所示:
表1:
