Description

多连接下的通信方法和通信设备 技术领域
本公开涉及通信领域，更具体地说，涉及一种多连接下的通信方法以及通信设备。
背景技术
在2018年5月份，IEEE(Institute of Electrical and Electronic Engineers，电气与电子工程师协会)成立了SG(study group)IEEE802.11be来研究下一代(IEEE802.11a/b/g/n/ac)Wi-Fi技术，所研究的范围为：320MHz的带宽传输、多个频段的聚合及协同等，期望能够相对于现有的IEEE802.11ax标准提高至少四倍的速率以及吞吐量，其主要的应用场景为视频传输、AR(Augmented Reality，增强现实)、VR(Virtual Reality，虚拟现实)等。
多个频段的聚合及协同是指设备间同时在2.4GHz、5.8GHz及6-7GHz的频段下进行通信，对于设备间同时在多个频段下通信需要定义新的MAC(Media Access Control，介质访问控制)机制来进行管理。此外，在IEEE802.11be中还期望能够支持低时延传输。
在IEEE802.11be标准中，将支持的最大带宽为320MHz(160MHz+160MHz)，此外还将支持240MHz(160MHz+80MHz)及IEEE802.11ax标准中所支持的带宽。
在IEEE802.11be标准中，站点(STA：Station)和接入点(AP：Access Point)可以是多连接设备(MLD：multi-link device)，即，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，在IEEE802.11be标准中，STA与AP之间可以存在多个连接。在IEEE802.11be标准中支持多连接的STA与支持多连接的AP通过一个连接建立初始关联，如果需要进行数据通信，则需要进行多连接建立。STA与AP之间的每个连接的 频段可能不一样，这样其覆盖范围也不一样，所以建立每个连接时所需的发射功率也不一样。然而，在现有标准中，只规定了当前连接下的发射功率，因此无法适用于多连接下的通信环境。

具体实施方式
供以下参照附图的描述，以帮助全面理解由所附权利要求及其等同物限定的本公开的各种实施例。本公开的各种实施例包括各种具体细节，但是这些具体细节仅被认为是示例性的。此外，为了清楚和简洁，可以省略对公知的技术、功能和构造的描述。
在本公开中使用的术语和词语不限于书面含义，而是仅被发明人所使用，以能够清楚和一致的理解本公开。因此，对于本领域技术人员而言，提供本公开的各种实施例的描述仅是为了说明的目的，而不是为了限制的目的。
应当理解，除非上下文另外清楚地指出，否则这里使用的单数形式“一”、“一个”、“所述”和“该”也可以包括复数形式。应该进一步理解的是，本公开中使用的措辞“包括”是指存在所描述的特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。
将理解的是，尽管术语“第一”、“第二”等在本文中可以用于描述各种元素，但是这些元素不应受这些术语的限制。这些术语仅用于将一个元素与另一个元素区分开。因此，在不脱离示例实施例的教导的情况下，下面讨论的第一元素可以被称为第二元素。
应该理解，当元件被称为“连接”或“耦接”到另一元件时，它可以直接连接或耦接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的术语“和/或”或者表述“……中的至少一个/至少一者”包括一个或多个相关列出的项目的任何和所有组合。
下面将结合附图详细描述本公开的实施方式。
在无线局域网中，一个基本服务集(BSS：Basic Service Set)可以由AP以及与AP通信的一个或多个STA构成。一个基本服务集可以通过其AP连接到分配系统DS(Distribution System)，然后再接入到另一个基本服务集，构成扩展的服务集ESS(Extended Service Set)。
AP可以包括软件应用和/或电路，以使无线网络中的其他类型节点可以通过AP与无线网络外部及内部进行通信。AP可以在不同的时频资源上与站点进行通信。作为示例，AP可以是配备有Wi-Fi(Wireless Fidelity，无线保真)芯片的终端设备或网络设备。作为示例，站点可以包括但不限于：蜂窝电话、智能电话、可穿戴设备、计算机、个人数字助理(PDA)、个人通信系统(PCS)设备、个人信息管理器(PIM)、个人导航设备(PND)、全球定位系统、多媒体设备、物联网(IoT)设备等。
在本公开的示例实施例中，STA和AP可以支持多连接的功能。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。
如果STA需要加入一个基本服务集，则需要与该基本服务集中的AP建立关联连接或重关联连接。通常，AP可以广播信标(beacon)帧；STA接收到信标帧后，向AP发送关联请求帧或重关联请求帧，并且AP针对STA发送的关联请求帧或重关联请求帧返回响应帧，当STA从接收到返回的响应帧，并且响应帧指示成功时，可以完成AP与STA之间的初始关联连接或重关联连接。
在现有标准中，AP广播的beacon帧携带发射功率限制信息元素，如下面的表格1所示。站点在关联请求帧或重关联请求帧中携带其支持的功率信息元素，如下面的表格2所示。
表格1.功率限制元素(Power Constraint Element)
Figure PCTCN2020104498-appb-000001
表格2.功率能力元素(Power Capability Element)
Figure PCTCN2020104498-appb-000002
在AP与STA之间存在多个连接的情况下，可能存在以下情形：当STA需要与作为MLD的AP建立初始关联或重关联时，STA可以在一个连接下侦听到来自AP的beacon帧，但是由于在侦听到beacon帧的连接下BSS负载(BSS  load)超过阈值，因此需在另一个连接下建立初始关联或重关联。其中，所述多个连接可以是不同频率下的多个连接，例如，2.4GHz、5GHz、6GHz下的连接等。在现有标准中，AP广播的beacon帧中仅携带了当前连接下的beacon帧的发射功率或发射功率限制，而没有对其他连接下的发射功率或发射功率限制作出规定。然而，在AP与STA之间存在多个连接的情况下，由于每个连接下(特别地，每个连接下的频段不同)，其覆盖范围也不一样，如果每个连接下采用单一的发射功率来发送消息帧，可能导致发送的消息帧无法达到接收方的情况，如图1所示。
在图1中，AP-MLD可以表示支持多连接通信功能的AP，Non-AP-MLD可以表示支持多连接通信功能的站点。图1中示出了AP-MLD与Non-AP-MLD之间存在三个连接(2.4GHz、5GHz、6GHz)，然而，这仅是示例性的，本公开的示例实施例不限于此。将理解的是，STA与AP之间的多连接可以表示STA与AP之间的处于不同频段下的多个信道。如图1所示，假设在三个连接下采用相同的发射功率，那么仅在2.4GHz连接下，AP-MLD可到达Non-AP-MLD，而在5/6GHz连接下，AP-MLD不可到达Non-AP-MLD。
如上所述，由于在现有标准中，AP广播的beacon帧中仅携带了当前连接下的beacon帧的发射功率，而不包含其他连接下的发射功率信息，因此不能够适应多连接下的通信环境。根据本公开的示例实施例提供的方案可以对每个连接下的发射功率信息进行定义，以便STA更加能够直接地确定在不同连接下的发射功率(关联请求帧或重关联请求帧的发射功率)。
图2是示出根据本公开的示例实施例的多连接下的通信方法的流程图。图2的方法可以是由控制端设备执行；在本公开实施例中，控制端设备可以包括但不限于AP或任何类型的控制器。
参照图2，在步骤210中，可以生成第一消息帧。根据本公开的示例实施例，第一消息帧可以是AP广播的beacon帧，然而，本公开的示例实施例不限于此，根据通信环境，第一消息帧可以是任何其他类型的帧。在一个示例实施例中，可以根据AP的通信能力、当前的通信环境来生成第一消息帧。在另一示例实施例中，可以直接获得预先存储或预先写入的第一消息帧，而省略生成第一消息帧的步骤210。
在步骤230中，在第一连接下广播第一消息帧。根据本公开的示例实施例，第一消息帧可以包括与多个连接对应的发射功率相关的信息。也就是说，第一消息帧不仅可以包括用于广播第一消息帧的第一连接下的发射功率信息，还可以包括除第一连接之外的其他连接下的发射功率信息。
根据本公开的示例实施例，与多个连接对应的发射功率相关的信息至少可以包括多个连接下的本地功率限制信息标识。此外，与多个连接对应的发射功率相关的信息还可以包括：连接标识，用于标识多个连接。也就是说，可以直接利用beacon帧中存在的功率限制元素(Power Constraint element)，并且在功率限制元素中可以包括与多个连接中的每个连接有关的本地功率限制信息标识以及每个连接所对应的标识，如下面的表格3所示。
表格3.功率限制元素(Power Constraint Element)
Figure PCTCN2020104498-appb-000003
在表格3中，Local Power Constraint 1、Local Power Constraint 2/difference compared to Link 1等可以对应于多个连接下的本地功率限制信息标识，Link 1、Link 2等可以对应于连接标识。
将理解，本地功率限制信息标识可以指示每个连接下的本地允许的(最大)发射功率。作为示例，多个连接下的本地功率限制信息标识均可以是绝对值或相对值。绝对值可以表示相应连接下的发射功率值，相对值可以表示相应连接下的发射功率相对于一个参考值的偏移值。例如，在表格3中，Local Power Constraint 1、Local Power Constraint 2等可以表示绝对值，即，分别表示Link 1和Link 2下的本地允许的(最大)发射功率。当将Link 1下的发射功率作为参考值时(或者，可以将发送/广播第一消息帧的第一连接下的发射功率作为参考值)，difference compared to Link 1可以表示Link 2的发射功率的偏移值，即，Link 2的发射功率与Link 1的发射功率之间的偏差，从而可以根据参考值(例如，Local Power Constraint 1)以及difference compared to Link 1获得Link 2的发射功率。然而，表格3所示的内容仅是示例性的，本公开的示例实施例不限于此， 例如，可以预先设置一个特定的其他发射功率值作为参考值，则多个连接下的本地功率限制信息标识均以相对值的形式来表示。
此外，连接标识也可以是绝对值或者相对值。绝对值可以表示每个连接的标识号，相对值可以表示每个连接的标识号相对于参考值的偏移。此外，也可以省略连接标识。也就是说，第一消息帧可以仅包括本地功率限制信息标识的信息组，并且本地功率限制信息标识在信息组中的位置隐含地与连接标识相对应。例如，参照表格3，可以仅包括Local Power Constraint 1、Local Power Constraint 2/difference compared to Link 1等，并且其位置也隐含地对应于连接标识。例如，可以根据每个连接所处于的频段的大小，对多个连接进行排序，然后在功率限制元素中仅依次示出与每个连接相对应的本地功率限制信息标识。在此情况下，可以不包括连接标识，并且本地功率限制信息标识在表格3中的顺序分别对应于多个连接的顺序。
根据本公开的另一示例实施例，与多个连接对应的发射功率相关的信息至少可以包括多个连接下的最大发射功率信息标识。也就是说，可以重新定义一个最大发射功率(Maximum transmission power)信息元素，来指示与多个连接中的每个连接有关的最大发射功率信息，如下面的表格4所示。
表格4.最大发射功率元素(Maximum Transmission Power Element)
Figure PCTCN2020104498-appb-000004
在表格4中，Maximum transmission power 1、Maximum transmission power 2/difference compared to Link 1可以对应于最大发射功率信息标识；Link 1、Link 2等可以对应于连接标识。
将理解，最大发射功率信息标识可以指示每个连接下的最大发射功率。也就是说，最大发射功率信息标识可以定义在每个连接下，不允许超过的发射功率值。作为示例，多个连接下的最大发射功率信息标识均可以是绝对值或相对值，并且连接标识也可以是绝对值或者相对值。绝对值或者相 对值的含义与上述参照表格3描述的含义相同，为了简明，在此省略重复的描述。可选地，第一消息帧可以仅包括最大发射功率信息标识的信息组，并且最大发射功率信息标识在信息组中的位置隐含地与连接标识相对应，这与上述的本地功率限制信息标识的信息组相类似，为了简明，在此省略重复的描述。
表格3的功率限制元素和/或表格4的最大发射功率元素，可以封装在第一消息帧(例如，beacon帧)中进行传输。
继续参照图2，在步骤250中，可以在另一连接下接收关联请求帧。具体地，可以在与步骤230中的第一连接不同的另一连接下，接收从接收到第一消息帧的设备发送的关联请求消息帧。根据示例实施例，关联请求消息帧可以包括关联请求帧或者重关联请求帧。根据示例实施例，关联请求消息帧是接收到第一消息帧的设备在该另一连接下以第一发射功率发送的，并且第一发射功率是接收到第一消息帧的设备基于与多个连接对应的发送功率信息相关的信息确定的该另一连接下的发射功率。将理解，在图2的方法中，步骤250可以被省略。也就是说，当用于发送第一消息帧的第一连接的信道环境允许时(例如，BSS load未超过阈值)，可以直接在第一连接下接收关联请求帧或者重关联请求帧。
由于接收到第一消息帧的设备(即，站点)可以根据第一消息帧中包括的如表格3或表格4的信息，因此可以确定另一连接下的第一发射功率。下面将参照图3和图4来进行详细描述。
参照图3，在步骤310中，可以在第一连接(例如，图4中的Link 1)下，接收第一消息帧。第一消息帧可以包括与多个连接对应的发射功率相关的信息。多个连接对应的发射功率相关的信息至少包括多个连接下的本地功率限制信息标识或者多个连接下的最大发射功率信息标识。多个连接对应的发射功率相关的信息还可以包括连接标识，用于标识多个连接本地功率限制信息标识、多个连接下的最大发射功率信息标识以及连接标识与参照步骤210、表格3和表格4描述的内容相同，为了简明，在此省略重复的描述。
在步骤330中，可以确定另一连接下的第一发射功率。将理解，当第 一连接下的BSS load未超过阈值时，该步骤330可以被省略，即，在步骤350中可以直接在第一连接下发送关联请求帧。
根据示例实施例，当STA接收到第一消息帧(例如，beacon帧)时，可以根据第一消息帧中的与多个连接对应的发射功率相关的信息，来确定与第一连接不同的另一连接(例如，图4中的Link 2)的第一发射功率。例如，STA接收到AP广播的beacon帧后，计算beacon帧的接收信号强度指示(RSSI：received signal strength indication)，然后基于beacon帧的RSSI计算路损，并且基于计算的路损以及与用于发送关联请求帧的连接的发送功率有关的信息(例如，本地功率限制信息标识或最大发射功率信息标识)，确定发送关联请求帧或重关联请求帧的发射功率。然而，这仅是示例性的，可以基于第一消息帧中的与多个连接对应的发送功率相关的信息，以各种方法来确定发送关联请求帧的发射功率，因此本公开的示例实施例不限于此。
在步骤350中，在另一连接(例如，图4的Link 2)下，以计算的第一发射功率发送关联请求消息帧。根据示例实施例，关联请求消息帧可以包括关联请求帧或者重关联请求帧。
参照图4，当STA从AP接收到关于关联请求帧或者重关联请求帧的响应帧并且响应帧指示成功时，STA与AP之间的初始关联连接或重关联连接建立完成。响应帧可以在Link 2上进行传输，然而本公开的示例实施例不限于此，例如，可以根据通信环境，在多个连接中的其他连接下传输响应帧。
根据本公开的示例实施例提供的通信方法能够在另一连接下与AP建立初始关联或重关联，能够适应多连接下的通信环境，并且提高网络的吞吐量。
图5是示出根据本公开的示例实施例的多连接下的通信设备500的示图。
参照图5，通信设备500可以包括处理模块510、发送模块520以及接收模块530。
处理模块510可以被配置为：生成第一消息帧。
发送模块520可以被配置为在第一连接下广播第一消息帧，其中，第一消息帧包括与多个连接对应的发射功率相关的信息。

根据本公开的示例实施例，关联请求消息帧是接收到第一消息帧的设备在另一连接下以第一发射功率发送的。第一发射功率是接收到第一消息帧的设备基于与多个连接对应的发送功率信息相关的信息确定的另一连接下的发射功率。

图5的通信设备500和图6的通信设备600的配置这仅是示例性的，本公开的示例实施例不限于此，例如可以包括通信设备500和图6的通信设备600可以包括更多或更少的模块。
