Description

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，涉及无线通信系统中的通信方法和通信设备。
背景技术
目前的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、5GHz及6GHz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，还期望多频段的聚合及协同能够支持低时延传输。
目前多频段的聚合及系统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)及其它带宽。
此外，目前的无线通信技术提出了支持低时延业务的需求，然而，现有标准中的EDCA(增强型分布式信道接入)参数不能够满足低时延业务的需求。例如，在目前的无线通信技术中加入了多AP协调功能，即，对AP之间的资源进行协调，例如，SR(空间复用：Spatial Reuse)、RTA(实时应用：real time application)资源的利用等等，但现有的标准是没有多AP协调机制。此外，如果要保证RTA业务的时延需求，则当RTA业务进行传输时，需要尽可能的避免受到干扰，但现有标准中的机制不能够满足这样的需求。

具体实施方式
提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。
除非另外定义，这里使用的所有术语(包括技术术语和科学术语)，具有与本公开所属领域中的普通技术人员的一般理解相同的意义。
在无线通信系统中，一个基本服务集(BSS)可以由接入点(AP：Access Point)设备以及与AP设备通信的一个或多个非AP(non-AP)设备。一个基本服务集可以通过其AP设备连接到分配系统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设备是用于无线网络的无线交换机，也是无线网络的核心。AP设备可以用作无线基站，主要是用来连接无线网络及有线网络的桥接器。利用这种AP设备，可以整合有线及无线网络。
作为示例，AP设备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。例如，AP设备可以是配备有Wi-Fi(Wireless Fidelity，无线保真)芯片的终端设备或网络设备。
作为示例，non-AP设备可以包括但不限于：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。在下文中，为了描述的方便，术语“non-AP设备”可以与站点(STA：station)或non-AP STA设备互换地使用。
在无线通信系统中，通常会存在多个AP，因此需要进行多AP协调功能，以对AP之间的资源(例如，SR、RTA资源等)进行协调，从而满足低时延业务的需求。为此，本公开的示例实施例提供了能够满足这种需求的通信方法和通信设备。
图1是示出根据实施例的通信方法的流程图。图1所示的通信方法可以应用于作为发送方的接入点设备。
参照图1，在步骤110中，可以确定第一消息帧，其中，第一消息帧可以包括目标唤醒时间(TWT：target wake-up time)信息。例如，第一消息 帧可以是信标(beacon)帧、动作(action)帧等，然而，这仅是示例性的，用于信息传输的其他类型的帧也是可行的。在本公开的实施例中，确定第一消息帧的方式可以有很多种，例如：接入点设备可以根据以下的至少一种情况来生成第一消息帧：网络情况、负载情况、发送/接收设备的硬件能力、业务类型、相关协议规定；对此本公开实施例不作具体限制。在本公开的实施例中，接入点设备还可以从外部设备获取该第一消息帧，对此本公开实施例不作具体限制。
在步骤120中，可以发送第一消息帧。第一消息帧(包括TWT信息)可以被对应的站点设备接收到，也可以被位于与作为发送的接入点设备的BSS不同的BSS中的其他接入点设备接收到，稍后将参照图3和图4对这两种情况分别进行描述。
根据实施例，TWT信息可以至少指示站点设备发送周期性业务或非周期性业务的时间信息。也就是说，作为发送方的接入点设备可以与对应的站点设备协商周期性业务或非周期性业务的时间信息。根据本公开的实施例，周期性业务或非周期性业务可以为实时应用(RTA)业务。
在发送周期性业务的情况下，TWT信息可以包括以下至少一项：周期性业务的周期性、每个周期的时长、周期性业务的有效期(或称为“时效性”)。根据实施例，周期性业务的周期性可以表示发送相邻周期性业务之间的时间间隔；每个周期的时长可以表示传输单个周期性业务所需要的时间；周期性业务的有效期可以表示执行周期性业务操作的有效时长，例如，有效时长可以以分钟、小时、天、月或年为单位。此外，在第一消息帧中，TWT信息还可以包括其他内容，例如，用于指示TWT的功能控制和/或诸如协商的TWT时间等的参数设置。
对于周期性业务，站点设备可以与接入点设备协商周期性业务的周期性、时长、时效性，当站点设备需要传输RTA业务时，站点设备可以使用分配的资源进行传输。
在一个实施例中，接入点设备可以在第一消息帧中携带为站点设备分配的资源，例如，资源单元(RU)、TWT参数、空间复用(SR)等。
在另一实施例中，接入点设备可以通过另外的帧(例如，触发(trigger) 帧等)为站点设备分配资源，以用于RTA业务传输。例如，如图2的步骤230所示，可以发送第二消息帧(例如，触发帧等)，其中，第二消息帧包括为需要发送周期性业务或非周期性业务的站点设备分配的资源信息。
此外，在图2的步骤230中，在需要发送非周期业务的站点设备通过竞争接入信道的情况下，通过第二消息帧为站点设备分配适合于实现UORA(上行链路OFDMA随机接入：uplink OFDMA random access)操作的参数值。该参数值可以包括OFDMA竞争窗口(OCW)的最小值(OCWmin)和最大值(OCWmax)等。
对于非周期性业务，AP在广播TWT信息后，在TWT信息中协商的TWT时间点发送触发帧，并且触发帧可以包括为非周期性RTA业务分配的资源，其中，当需要传输非周期性RTA业务的站点通过竞争的方式接入信道时，例如，通过重用UORA技术接入信道时，参数OCWmin和OCWmax可以设置的较小(例如，比现有技术中的UORA设置得小)，这样站点设备能够更容易得地到传输资源。因此，可以实现低时延需求，以满足RTA业务的时延需求。
此外，TWT信息可以包括空间复用(SR)信息。例如，响应于站点设备存在多个天线并且支持方向性传输及判断OBSS(重叠基本服务集：overlapping basis service set)数据包的功率值等信息，接入点设备可以将SR信息包括在TWT信息中，以适用于周期性业务和非周期性业务的传输。
根据本公开的实施例，站点设备和接入点设备可以是支持多连接通信的设备，可以简称为多连接设备(MLD：multi-link device)，即，在站点设备与接入点设备之间可以存在多个连接。多个连接可以处于不同的频率，例如，处于2.4GHz、5GHz、6GHz下的连接等，或者可以是特定频率(例如，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。在此情况下，TWT信息可以包括多个连接中的每个连接下的发送周期性业务或非周期性业务的时间信息。可选择地，TWT信息还可以包括与所述多个连接中的每个连接相对应的连接标识。通过这样的TWT信息，接入点设备和站点设备可以协商每个连接下的周期性业务或非周期性 业务的传输时间。
在图2的步骤210中，接入点设备可以向站点发送第一消息帧，该步骤可以类似于图1的步骤110；在以上实施例中描述的步骤230可以作为图1的通信方法中的子操作；在图2的步骤250中，接入点设备可以根据协商的传输时间，从站点设备接收周期性/非周期性RTA业务。
在以上的实施例中描述了：作为发送方的接入点设备发送的TWT信息被站点设备接收到，从而与站点设备协商周期性业务或非周期性业务的传输时间。下面描述其他接入点设备可以接收作为发送方的接入点设备发送的第一消息帧的实施例。
根据本公开的实施例，TWT信息可以包括在精简邻居报告(RNR：reduced neighbor report)信息元素中。RNR信息元素可以携带在第一消息帧中。
在存在多个接入点设备的情况下，其他接入点设备可以接收作为发送方的接入点设备发送的第一消息帧，从而其他接入点设备可以根据第一消息帧携带的RNR信息元素中的TWT信息获得作为发送方的接入点设备设置的RTA业务传输的时间点、空间复用等信息，并且根据这些信息来规划本BSS中的RTA业务传输的时间点、空间复用等。也就是说，多个AP可以直接协调RTA业务的通信时间，包括SR(spatial reuse)、时间段信息等。
根据本公开的实施例，虽然未示出，但是图1所示的通信方法还可以包括：通过第一接入点设备广播第一消息帧，其中，第一消息帧被不同于第一接入点设备的第二接入点设备接收到。第一接入点设备可以是如上所述的作为发送方的接入点设备，第二接入点设备可以是位于其他BSS中的接入点设备。
根据本公开的实施例，在第一接入点设备和第二接入点设备支持同时发送和接收(STR)功能的情况下，在第一接入点设备和第二接入点设备所支持的多个连接中的不同的连接下，周期性业务或非周期性业务的传输时间重叠；在第一接入点设备和第二接入点设备所支持的多个连接中的同一连接下，周期性业务或非周期性业务的传输时间不重叠。
例如，第一接入点设备利用AP1来表示，第二接入点设备利用AP2来表示，它们分别属于不同的多连接设备；第一接入点设备AP1与站点设备STA1通信，第二接入点设备AP2与站点设备STA2通信。如果第一接入点设备AP1和第二接入点设备AP2具有STR功能，则在不同连接下的RTA业务时间可以重叠，但同一个连接下RTA业务时间不重叠。根据本公开的实施例，同一个连接表示：接入点设备工作在同一工作频段但是分别属于不同的MLD。此外，如果在不同连接下RTA业务时间重叠，则需要考虑STA是否支持STR功能，保证接入点设备回复给站点设备的确认消息帧(ACK)不受到干扰。
图3是示出根据实施例的另一通信方法的流程图。图3所示的通信方法可以应用于站点设备。
参照图3，在步骤310中，可以接收第一消息帧。第一消息帧可以是从作为发送方的接入点设备发送的。第一消息帧可以包括目标唤醒时间(TWT)信息，该TWT信息可以至少指示站点发送周期性业务或非周期性业务的时间信息。周期性业务或非周期性业务可以是周期性RTA业务或非周期性RTA业务。
下面描述图3所示的通信方法应用于站点设备的实施例，即，在步骤310中，站点设备接收到第一消息帧。
对于周期性业务，站点设备可以与AP协商其周期性、时长、时效性，当站点设备需要RTA业务传输时，站点设备可以使用分配的资源进行传输。例如，站点设备可以接收第二消息帧(例如，触发帧)，其中，第二消息帧可以包括为需要发送周期性业务的站点设备分配的资源信息。
对于非周期性业务，AP在广播TWT信息后，在TWT时间点向站点设备发送第二消息帧(例如，触发帧)，在触发帧中包含为非周期性RTA业务分配的资源。如果需要传输RTA业务的站点通过竞争的方式接入信道，譬如重用UORA，则站点设备可以从第二消息帧(例如，触发帧)获取适合于实现UORA操作的参数值，例如，获取OCWmin及OCWmax。根据本公开的实施例，所获取的OCWmin和OCWmax比现有技术中的UORA设置得要小，从而站点设备能够更容易得到传输资源。
根据本公开的实施例，TWT信息可以包括空间复用信息。如果站点设备支持方向性传输，则可以从TWT信息获取SR信息，以用于周期性业务和非周期性业务。
根据本公开的实施例，站点设备可以是支持多连接通信的多连接设备。在此情况下，TWT信息可以包括：多个连接中的每个连接下的发送周期性业务或非周期性业务的时间信息和/或与多个连接中的每个连接相对应的连接标识。
在图3中，关于第一消息帧、TWT信息、第二消息帧可以类似于参照图1和图2的描述，为了简明，在此省略重复的描述。
在步骤320中，站点设备可以基于第一消息帧执行通信操作。例如，站点设备根据协商的周期性/非周期性RTA业务的时间，在一个或多个连接下进行RTA业务传输。
图4是示出根据实施例的另一通信方法的流程图。图4所示的通信方法可以应用于作为接收方的接入点设备(例如，第二接入点设备)。
在步骤410中，第二接入点设备可以接收由不同于第二接入点设备的第一接入点设备广播的第一消息帧。根据实施例，第一消息帧可以包括TWT信息，该TWT信息可以至少指示与第一接入点设备通信的站点设备发送周期性业务或非周期性业务的时间信息。
在步骤420中，第二接入点设备可以基于第一消息帧中的TWT信息，设置与第二接入点设备通信的站点设备的周期性业务或非周期性业务的传输时间。根据本公开的实施例，TWT信息可以包括在精简邻居报告(RNR)信息元素中，从而第二接入点设备可以从RNR信息元素中获取TWT信息。
根据本公开的实施例，在第一接入点设备和第二接入点设备支持同时发送和接收(STR)功能的情况下，在第一接入点设备和第二接入点设备所支持的多个连接中的不同的连接下，周期性业务或非周期性业务的传输时间重叠；在第一接入点设备和第二接入点设备所支持的多个连接中的同一连接下，周期性业务或非周期性业务的传输时间不重叠。
在步骤430中，第二接入点设备可以与对应的站点设备执行通信操作， 例如，周期性业务或非周期性业务可以根据设置的RTA业务传输时间进行传输。
在本公开的一个实施例中，TWT信息可以嵌套在RNR信息元素中并且RNR信息元素可以包括在例如信标帧(即，第一消息帧)中。在其他AP(即，第二接入点设备)接收到AP(即，第一接入点设备)广播的信标帧的情况下，其他AP(即，第二接入点设备)可以根据RNR信息元素中的信息，规划本BSS中的站点设备的RTA业务传输的时间点、空间复用等。
例如，STA1与AP1、STA2与AP2属于不同的MLD，如果AP1、AP2具有STR功能，则在各个连接下的RTA业务时间可以重叠，但是同一个连接下RTA业务时间不重叠。如果不同连接下RTA业务时间重叠，则需要考虑站点设备是否支持STR功能，保证接入点设备回复给站点设备的确认消息帧(ACK)不受到干扰。
根据本公开的实施例的上述的通信方法能够使得接入点设备直接协调RTA业务的通信时间，包括SR、时间段信息等，提高频谱的利用效率，满足RTA业务的时延需求。
应该理解的是，虽然图1至图4的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。此外，附图的流程图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。此外，不同流程图中的各个步骤也可以进行组合。

图5所述的通信设备500可以应用于作为发送方的接入点设备。处理模块510可以被配置为：确定第一消息帧，其中，第一消息帧可以包括目标唤醒时间(TWT)信息，TWT信息可以至少指示站点设备发送周期性业务或非周期性业务的时间信息；通信模块520可以被配置为：发送第一消 息帧。在该情况下，通信设备500的处理模块510和通信模块520可以执行参照图1描述的通信方法，为了简明，省略重复的描述。

图5所述的通信设备500可以应用于作为接收方的接入点设备(如上所述的第二接入点设备)。通信模块520可以被配置为：接收由不同于第二接入点设备的第一接入点设备广播的第一消息帧，其中，第一消息帧包括目标唤醒时间(TWT)信息，TWT信息至少指示与第一接入点设备通信的站点设备发送周期性业务或非周期性业务的时间信息；处理模块510可以被配置为：基于第一消息帧中的TWT信息，设置与第二接入点设备通信的站点设备的周期性业务或非周期性业务的传输时间，并且控制通信模块520执行通信操作。在该情况下，通信设备500的处理模块510和通信模块520可以执行参照图4描述的通信方法，为了简明，省略重复的描述。
此外，图5所示的通信设备500仅是示例性的，本公开的实施例不限于此，例如，通信设备500还可以包括其他模块，例如，存储器模块等。此外，通信设备500中的各个模块可以组合成更复杂的模块，或者可以划分为更多单独的模块。
