具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统,例如:无线局域网(WLAN)、无线保真(Wireless Fidelity,WiFi)或其他通信系统等。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括接入点(Access Point,AP)110,以及通过接入点110接入网络的站点(STATION,STA)120。
在一些场景中,AP或称AP STA,即在某种意义上来说,AP也是一种STA。
在一些场景中,STA或称非AP STA(non-AP STA)。
通信系统100中的通信可以是AP与non-AP STA之间的通信,也可以是non-AP STA与non-AP STA之间的通信,或者STA和peer STA之间的通信,其中,peer STA可以指与STA对端通信的设备,例如,peer STA可能为AP,也可能为non-AP STA。
AP相当于一个连接有线网和无线网的桥梁,主要作用是将各个无线网络客户端连接到一起,然后将无线网络接入以太网。AP设备可以是终端设备(如手机)或者网络设备(如路由器)。该终端设备或者网络设备具有实现通信功能的芯片,例如WLAN或者WiFi芯片。
应理解,STA在通信系统中的角色不是绝对的,例如,在一些场景中,手机连接路由的时候,手机是non-AP STA,手机作为其他手机的热点的情况下,手机充当了AP的角色。
AP和non-AP STA可以是应用于车联网中的设备,物联网(Internet Of Things,IoT)中的物联网节点、传感器等,智慧家居中的智能摄像头,智能遥控器,智能水表电表等,以及智慧城市中的传感器等。
在一些实施例中,non-AP STA可以支持802.11be制式。non-AP STA也可以支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种当前以及未来的802.11家族的无线局域网(wireless local area networks,WLAN)制式。
在一些实施例中,AP可以为支持802.11be制式的设备。AP也可以为支持802.11ax、802.11ac、802.11n、802.11g、802.11b及802.11a等多种当前以及未来的802.11家族的WLAN制式的设备。
在本申请实施例中,STA可以是支持WLAN/WiFi技术的手机(Mobile Phone)、平板电脑(Pad)、电脑、虚拟现实(Virtual Reality,VR)设备、增强现实(Augmented Reality,AR)设备、工业控制(industrial control)中的无线设备、机顶盒、无人驾驶(self driving)中的无线设备、车载通信设备、远程医疗(remote medical)中的无线设备、智能电网(smart grid)中的无线设备、运输安全(transportation safety)中的无线设备、智慧城市(smart city)中的无线设备或智慧家庭(smart home)中的无线设备、无线通信芯片/ASIC/SOC/等。
WLAN技术可支持频段可以包括但不限于:低频段(例如2.4GHz、5GHz、6GHz)、高频段(例如45GHz、60GHz)。
图1示例性地示出了一个AP STA和两个non-AP STA,可选地,该通信系统100可以包括多个AP STA以及包括其它数量的non-AP STA,本申请实施例对此不做限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
(1)带宽与RU(Resource Unit,资源单元)尺寸(size)的对应关系
带宽 RU尺寸
20MHz 242-tone
40MHz 484-tone
80MHz 996-tone
160MHz 2×996-tone
320MHz 4×996-tone
(2)PPDU格式
EHT(Extremely high throughput,极高吞吐量)PPDU有2种形式:EHT MU(Multi-User,多用户)PPDU(Physical Layer Protocol Data Unit,物理层协议数据单元)和EHT TB(Trigger based,基于触发的)PPDU。
(a)EHT MU PPDU
EHT MU PPDU的格式如图2所示,用来传输给1个或多个用户。在EHT MU PPDU中,L-STF(Non-HT Short Training field,非高吞吐量的短训练字段)、L-LTF(Non-HT Long Training field,非高吞吐量的长训练字段)、L-SIG(Non-HT SIGNAL field,非高吞吐量的信号字段)、U-SIG(Universal SIGNAL field,通用信号字段)和EHT-SIG(EHT SIGNAL field,EHT信号字段)称为pre(每)-EHT调制字段;EHT-STF(EHT Short Training field,EHT高吞吐量的短训练字段)、EHT-LTF(EHT Long Training field,EHT高吞吐量的长训练字段)、Data(数据)和PE(Packet Extension field,包拓展字段)称为EHT调制字段。
(b)EHT TB PPDU
EHT TB PPDU的格式如图3所示,用于传输来自一个AP的响应触发帧。在EHT TB PPDU中, L-STF、L-LTF、L-SIG和U-SIG称为pre-EHT调制字段;EHT-STF、EHT-LTF、Data和PE称为EHT调制字段。EHT TB PPDU中的EHT-STF字段持续时间是EHT MU PPDU中的EHT-STF字段持续时间的2倍。
(3)EHT PPDU中U-SIG字段指示带宽
U-SIG字段携带解码EHT PPDU所需的信息,包含U-SIG-1和U-SIG-2。EHT MU PPDU中的U-SIG字段内容如下表所示。其中B0-B19是version independent field(版本无关字段),剩余的bits(比特)为version dependent field(版本有关字段)。不论PHY(Physical layer,物理层)的版本如何,PHY都要上报version independent field给MAC(Medium Access Control,介质访问控制)层。
参见表1,对于带宽的指示,Bandwidth(带宽)子字段共3比特,其中值0~5分别指示带宽20MHz、40MHz、80MHz、160MHz、320-1MHz、320-2MHz。这些值不能用于指示其他类型的带宽。此外,Bandwidth子字段属于version independent field,所以legacy(旧)STA(Station,站点)探测到EHT MU PPDU后,依然会把带宽信息上报给MAC层。

图4是根据本申请一实施例的通信方法400的示意性流程图。该方法可选地可以应用于图1所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S410、站点发送和/或接收第一信息,该第一信息用于指示传输资源的带宽信息和/或打孔信息。
在本申请实施例中,站点可以是AP STA,也可以是非AP STA。第一站点可以向第二站点发送第一信息。第一站点也可以从第二站点接收第一信息。第一信息可以携带在数据包中。
在一种实施方式中,该传输资源用于传输的数据包为PPDU。该PPDU可以是UHR(Ultra-High Reliability,超高可靠性)PPDU,例如non-OFDMA(Orthogonal Frequency Division Multiple Access,正交频分多址)UHR PPDU。
在一种实施方式中,该第一信息包括第一带宽指示信息和/或第二带宽指示信息。
在本申请实施例中,可以采用一个指示信息指示传输资源的带宽,也可以采用两个指示信息组合以共同指示传输资源的带宽。例如,PPDU中包括第一带宽指示信息和/或第二带宽指示信息,该第一带宽指示信息和/或该第二带宽指示信息可以指示PPDU的传输资源的带宽。
在一种实施方式中,该第一带宽指示信息和/或第二带宽指示信息用于指示该传输资源的带宽信息,该传输资源用于传输数据包。
在一种实施方式中,该第一信息指示新增带宽信息的方式包括以下至少之一:

该第二带宽指示信息的取值指示新增带宽信息;
该第一带宽指示信息的取值和该第二带宽指示信息的取值构成的组合取值指示新增带宽信息;其中,组合取值的数量与新增带宽的数量相同。
在本申请实施例中,新增带宽也可以称为新增信道带宽,新增带宽可以包括在相关技术的最大带宽或较大带宽的基础上,新增的带宽。例如,5GHz频段的最大带宽是160MHz。6GHz频段的最大带宽是320MHz。新增带宽可以大于该最大带宽。新增带宽也可以大于该较大带宽例如大于6GHz频段的较大带宽160MHz。例如新增带宽可以为5GHz频段的240MHz、480MHz或640MHz。再如,新增带宽可以为6GHz频段的240MHz、480MHz或640MHz。新增带宽也可以是其他值。此外,第一带宽指示信息和/或第二带宽指示信息还可以兼容相关技术中的其他带宽。其中,第二带宽指示信息可以是扩展的指示信息,根据需要指示的带宽类型的数量,可以灵活设置第二带宽指示信息所占的比特数量。
在一种实施方式中,该第一带宽指示信息的取值包括未占用取值和/或已占用的相关带宽取值。
在本申请实施例中,未占用取值可以包括一个或多个保留值,已占用的相关带宽取值可以包括已经用于指示其他带宽的取值。相关带宽可以与新增带宽具有一定关系,例如相关带宽可以包括较大带宽,例如大于某个设定值的带宽。可以将已占用的相关带宽取值修改为指示新增带宽信息,也可以利用已占用的相关带宽取值与其他值组合以共同指示新增带宽信息。例如,相关带宽取值为3,通常指示的相关带宽为160MHz。本申请实施例可以用于取值3指示240MHz。这样,在支持240MHz的设备中,取值3可以单独指示或组合指示240MHz,在不支持240MHz的设备中取值3可以兼容指示160MHz。这样 有利于兼容相关技术中的其他带宽。
在一种实施方式中,该第一信息指示一种新增带宽信息的方式包括以下至少之一:

在本申请实施例中,如果第一带宽指示信息的未占用取值足够多,可以利用第一带宽指示信息单独指示更多例如三个、四个、五个等新增带宽信息。如果第一带宽指示信息的未占用取值不够多,例如仅有两个未占用取值,可以采用第一带宽指示信息指示部分新增带宽信息,采用扩展的第二带宽指示信息指示剩余的新增带宽信息。此外,也可以采用第一带宽指示信息和第二带宽指示信息构成所需数量的组合取值,共同指示新增带宽信息。

本申请实施例适用于新一代Wi-Fi通信,例如:超高可靠性(Ultra-High Reliability,UHR),基于新的信道带宽,例如:240MHz,480MHz(包含480MHz-1和480MHz-2)和640MHz(包含640MHz-1和640MHz-2),可以提供新的UHR PPDU,该PPDU的U-SIG中信令指示,示例如下:

1.UHR PPDU
UHR PPDU有2种形式:UHR MU PPDU和UHR TB PPDU。
(1)UHR MU PPDU
UHR MU PPDU的格式如图6所示,用来传输给1个或多个用户。其中,L-STF字段主要用于信号探测,自动增益控制,时间同步和粗略频偏估计;L-LTF字段主要用于信道估计和进一步频偏估计;L-SIG字段用于传送速率和长度信息;RL-SIG是L-SIG的重复;U-SIG和UHR-SIG字段用于携带解码PPDU的信息;UHR-STF字段用于改进MIMO(Multiple-Input Multiple-Output,多输入多输出)传输中的自动增益控制估计;UHR-LTF用于从星座映射输出到接收链路的MIMO信道估计;Data字段传输信息;PE字段是包的拓展。在UHR MU PPDU中,L-STF、L-LTF、L-SIG、U-SIG和UHR-SIG称为pre-UHR调制字段;UHR-STF、UHR-LTF、Data和PE称为UHR调制字段。
(2)UHR TB PPDU

2.UHR PPDU中U-SIG字段的设计
U-SIG字段携带解码UHR PPDU所需的信息。U-SIG字段的整数字段以无符号二进制格式传输,LSB(Least Significant Bit,最低有效位)在前,其中LSB位于编号最低的位位置。
本申请实施例提供了Bandwidth指示,和关于non-OFDMA传输的信道打孔模式指示。
(1)带宽指示
UHR PPDU的新增带宽为240MHz、480MHz或640MHz,其信道化如下。
240MHz信道由5GHz频段下3个连续的80MHz IEEE信道组成。
480MHz信道由6GHz频段下任意3个相邻的160MHz IEEE信道组成,有2种类型:480MHz-1和480MHz-2。其中,480MHz-1的信道中心频率索引为47,143;480MHz-2的信道中心频率索引为79, 175。
640MHz信道由6GHz频段下任意4个相邻的160MHz IEEE信道组成,有2种类型:640MHz-1和640MHz-2。其中,640MHz-1的信道中心频率索引为63;640MHz-2的信道中心频率索引为159。
本申请实施例可以指示240MHz、480MHz或640MHz其中之一,或指示其中之二,或同时指示。
若U-SIG字段中Bandwidth子字段值为保留值(reserved),本申请实施例可以将一个或多个保留值定义为未使用的Bandwidth子字段值。
(a)指示240MHz、480MHz或640MHz带宽的其中之一
Option 1:利用未使用的Bandwidth子字段值指示
U-SIG字段中Bandwidth子字段为3比特(取值为0~7),其中值0~5分别指示20MHz、40MHz、80MHz、160MHz、320MHz-1和320MHz-2带宽,值6~7为reserved。
本申请实施例可以利用未使用的Bandwidth子字段的值6或7指示240MHz、480MHz或640MHz带宽的其中之一。U-SIG字段具体内容如表2所示。
表2 UHR MU PPDU的U-SIG字段指示240MHz、480MHz或640MHz的其中之一

Option 2:利用Bandwidth子字段值3或4~5和1比特Bandwidth Extension子字段值的组合来指示。
U-SIG字段中Bandwidth子字段为3比特(取值为0~7),其中值0~5分别指示20MHz/40MHz/80MHz/160MHz/320MHz-1/320MHz-2带宽值6~7为reserved。
为了使第三方legacy STA获取PPDU带宽信息及恰当地设置NAV,例如,当工作频段为5GHz且UHR PPDU带宽为240MHz时,legacy STA因支持的最大带宽为160MHz而无法识别240MHz带宽。此时如果该legacy STA能够把240MHz PPDU带宽识别成160MHz PPDU带宽可能会有助于它恰当地设置NAV。为实现这个目的,当UHR PPDU带宽为240MHz时,可以参考160MHz对应的取值,将U-SIG中Bandwidth子字段置为3。
再例如,当工作频段为6GHz且UHR PPDU带宽为480MHz时,legacy STA因支持的最大带宽为320MHz而无法识别480MHz带宽。此时如果该legacy STA能够把480MHz PPDU带宽识别成320MHz PPDU带宽可能会有助于它恰当地设置NAV。为实现这个目的,当UHR PPDU带宽为480MHz时,可以参考160MHz对应的取值,将U-SIG中Bandwidth子字段置为4或5。
基于此,本申请实施例提出使用Bandwidth子字段的值3、4或5的至少之一和1比特Bandwidth Extension子字段值的组合,来指示240MHz、480MHz或640MHz带宽之一。
例如,Bandwidth子字段的值3和Bandwidth Extension子字段的值0指示240MHz带宽;Bandwidth子字段的值3和Bandwidth Extension子字段的值1指示160MHz带宽。
再如,Bandwidth子字段的值4~5和Bandwidth Extension子字段的值0指示480MHz-1和480MHz-2带宽;Bandwidth子字段的值4~5和Bandwidth Extension子字段的值1指示320MHz-1和320MHz-2带宽。
再如,Bandwidth子字段的值4~5和Bandwidth Extension子字段的值0指示640MHz-1和640MHz-2带宽;Bandwidth子字段的值4~5和Bandwidth Extension子字段的值1指示320MHz-1和320MHz-2带宽。
