具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请实施例相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本申请实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”、“一个”和“该”也旨在包括多数形式,除非上下文清 楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开实施例范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
在2018年,电气和电子工程师协会(Institute of Electrical and Electronics Engineers,IEEE)802.11成立了研究组(Study Group,SG)来研究下一代主流Wi-Fi技术,所研究的范围包括:320MHz的带宽传输,多个频段的聚合及协同等,所提出的愿景相对于现有的802.11ax提高至少四倍的速率以及吞吐量,其主要的应用场景包括视频传输、增强现实(AR,Augmented Reality)传输、虚拟现实(VR,Virtual Reality)传输等。
其中,多个频段/连接的聚合是指设备同时在多个频段下(如2.4GHz、5GHz及6-7GHz)发送数据,这样的好处包括:1、提高整个系统的吞吐量(在每个频段下发送不同内容的数据);2、提高数据发送/接收的成功率(在每个频段下发送统一内容的数据)。
为了更进一步提高系统的吞吐量,在IEEE802.11be中,有些设备可能支持同时发送及接收(在多个连接下接收和发送不相互干扰),有些设备可能只支持多连接发送或接收,有些设备可能只支持单连接接收或发送。
相关技术中,针对基本服务集(Basis Service Set,BSS)中存在着上述描述能力的设备的情况,提出了一种保证在通信中相互不干扰的方法,设备判断能否在物理层发送的依据是基于信道能量检测(Energy Detection,ED)机制,设备判断能否在MAC层发送的依据是基于网络分配向量(Network Allocation Vector,NAV)机制,当ED值大于或等于阈值时,设 置NAV为繁忙,则随机退避;当ED值小于阈值时,则设置NAV为空闲,进行发送。然而,该方法只是给出了在一个连接下NAV的设置情况,而在多连接下,特别是存在着三种能力(多连接同时发送及接收、多连接发送或接收、以及单连接发送或接收)的设备在BSS中,在设备将要进行数据发送时,设备怎样感知信道且设备应该如何设置NAV尚无规范。
基于上述无线通信系统,如何在不对其他设备造成干扰的情况下,提高频谱的利用效率,提出本公开方法各个实施例。
图1是根据一示例性实施例示出的一种多连接通信下网络分配向量的确定方法的流程图,该多连接通信下网络分配向量的确定方法应用于第一设备中,所述第一设备可以为站点(Station,STA)设备,具体可以为移动终端、平板等设备、或为接入点(Access Point,AP)设备,具体可为路由器、网关等设备。如图1所示,该多连接通信下网络分配向量的确定方法包括以下步骤。
在步骤S11中,在多个连接下的第一连接生成第一数据帧;其中,所述多个连接包括所述第一连接;
在步骤S12中,获取所述多个连接中第二设备的能力信息值;
在步骤S13中,根据所述第一设备的能力信息值及所述第二设备的能力信息值,设置所述第一设备在所述第一连接下的网络分配向量。
本公开实施例中,所述第二设备可以为站点设备、或为接入点设备。
本公开实施例中,所述第一数据帧是由所述第一设备生成的数据帧。
本公开实施例中,所述能力信息值,为:
第一取值,用于指示在多个连接上支持同时发送及接收;或者,
第二取值,用于指示在多个连接上支持发送或接收;或者,
第三取值,用于指示在单个连接上支持发送或接收。
其中,所述第一取值、所述第二取值和所述第三取值,是三个不同的值。实际应用中,具体如何赋值可根据实际需求进行设定或调整。
其中,所述多个连接为2.4GHz、5GHz、6-7GHz频段下建立的基本服务集BSS或在前述三个频段下中的任一频段建立的带宽相同或不同的基本服务集BSS,譬如20MHz、40MHz或80MHz带宽等等。
其中,第二设备的能力信息值,是指第一设备可以通过第二设备传输的第二数据帧的物理头中的信号域(SIGNAL)中获得。能力信息值具体可以用两个比特位标识,比如,“00”表示单连接发送或接收,“01”表示多连接发送或接收,“10”表示多连接发送及接收。
图2示出了的能力信息的格式示意图,如图2所示,能力信息值的格式,包括元素标识(Element ID)、长度(Length)、信息(information)三项内容,其中,所述信息用于为具体取值。示例性地,information为“00”表示设备只支持单连接发送或接收;information为“01”表示设备同时支持多连接发送或接收;information为“10”表示设备同时支持多连接发送及接收。
本实施例中,并不对能力信息值的获取方式进行强制性限定。
在一些实施例中,接入点设备通过信标(beacon)帧、或探测响应(probe response)帧、或关联响应(association request)帧中发送能力信息值,如发送表示其支持在多连接下同时接收及发送的能力信息值。
在一些实施例中,站点设备通过探测请求(probe request)帧、或关联请求(association request)帧中发送其能力信息值,比如发送表示其支持在多连接下同时发送及接收的能力信息值,或发送表示其支持多连接同时发送或接收的能力信息值,或发送表示其支持单连接发送或接收的能力信息值。
