Description

通信方法和装置
本申请要求于2021年05月20日提交国家知识产权局、申请号为202110554343.2、申请名称为“通信方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其是涉及一种通信方法和装置。
背景技术
现有无线局域网(wireless local area network,WLAN)通信系统从802.11a/b/g标准开始,历经多代,如802.11n标准、802.11ac标准、802.11ax标准和802.11be标准。基于前述标准,通信装置与通信装置之间可以通过物理层协议数据单元(physical layer protocol data unit,PPDU)进行通信。其中,PPDU可以包括媒体介入控制协议数据单元(medium access control protocol data unit,MPDU)。
示例性的,802.11ax标准中,MPDU可以包括高吞吐率(high throughput,HT)控制字段,HT控制字段可以包括一个或多个控制标识符和每个控制标识符对应的控制信息。当控制标识符的值为2时,控制信息可以为26比特的高效链路自适应(HE link adaptation,HLA)控制子字段。
其中,HLA控制子字段可以包括3比特的空间流数(number of spatial streams,NSS)子字段、2比特的带宽(band width,BW)子字段以及其他子字段。
随着标准的不断演进,相比于802.11ax标准,802.11be标准或未来无线保真(wireless fidelity,Wi-Fi)标准可以支持更多的特性和功能,但是,802.11ax标准中已经预先定义了HLA控制子字段的各个子字段的比特数和含义,沿用HLA控制子字段无法支持更多的特性和功能。因此,如何合理设计802.11be标准或未来Wi-Fi标准对应的链路自适应控制子字段成为亟待解决的技术问题。
发明内容
本申请提供了一种通信方法和装置,使得在802.11be标准或未来Wi-Fi标准中,若继续沿用HLA控制子字段可以支持更多的特性和功能。

基于第一方面,结合非请求式MFB子字段的取值,将MRQ和UL EHT TB PPDU MFB用一比特来指示,相比于802.11ax标准中将MRQ和UL EHT TB PPDU MFB分别用1比特指示,可以节约1比特,进而可以利用该节约出来的1比特支持802.11be标准或未来Wi-Fi标准中更多的特性和功能,使得第一字段在不增加比特数的情况下(即仍为26比特) 反馈更多信息。

一种可能的设计中,第一字段还包括比特数为2的调制和编码方案MCS请求序列指示或部分PPDU参数子字段。
基于该可能的设计,相比于802.11ax标准,本申请实施例中将调制和编码方案MCS请求序列指示或部分PPDU参数子字段从3比特压缩至2比特,在满足802.11be标准或未来Wi-Fi标准中对调制和编码方案MCS请求序列指示或部分PPDU参数子字段的需求的同时,可以节省比特数,进而可以利用节省的1比特支持802.11be标准或未来Wi-Fi标准中更多的特性和功能,使得第一字段在不增加比特数的情况下(即仍为26比特)反馈更多信息。
一种可能的设计中,第一字段还包括比特数为1的发送端波束成形子字段。

具体实施方式
在描述本申请实施例之前,对本申请实施例涉及的技术术语进行描述。
无线局域网(wireless local area network,WLAN)通信系统:从802.11a/b/g标准开始,历经多代,如802.11n标准、802.11ac标准、802.11ax标准和802.11be标准等标准;其中,对于802.11be标准以前的标准,如802.11a/b/g标准、802.11n标准、802.11ac标准、802.11ax标准也可以统称为非802.11be标准。
其中,对于802.11n标准之前的标准,如802.11a/b/g等标准可以统称为非高吞吐率(non-high throughput,non-HT)标准;802.11n标准可以称为高吞吐率(high throughput,HT)标准;802.11ac标准可以称为非常高吞吐率(very high throughput,VHT)标准;802.11ax标准可以称为高效(high efficient,HE)标准,也可以称为第6代无线保真(the sixth wireless fidelity,Wi-Fi 6)标准;802.11be标准可以称为极高吞吐率(extremely high throughput,EHT)标准,也可以称为Wi-Fi 7标准。
示例性的,参照表1,上述各个标准允许传输的带宽、空时流数、编码调制策略以及所支持的最大数据速率可以如下述表1所示:
表1
Figure PCTCN2022093093-appb-000001
需要说明的是,上述表1中的各个标准均采用正交频分复用(orthogonal frequency division multiplexing,OFDM)模式,802.11b标准由于采用非OFDM模式,因此没有列在表1中。
OFDM:即利用子载波的正交性在容许的范围内,将子载波间隔压缩到最小,可以保证形成多路并行且互不干扰的通路,同时又能提升无线通信系统的频率利用效率,是当前无线通信系统的基本传输方式,广泛应用于长期演进(long term evolution,LTE)、全球微波接入互操作性(worldwide interoperability for microwave access,WiMAX)、Wi-Fi等无线通信系统。进一步的,OFDM也可以应用到固网传输,比如光纤、铜绞线、电缆等传输方式。
基于上述对OFDM的描述,如果将OFDM的互不干扰的子载波分配给多个用户,则 可以利用OFDM来实现多用户的接入或者数据传输,即正交频分多址(orthogonal frequency division multiple access,OFDMA)。采用OFDMA可以实现多用户数据的并行传输,有效提高数据传输的并发性。
链路自适应(link adaptation,LA):对于无线通信而言,其信道的状况通常会随时间的变化而发生变化,即信道会受路损(path loss)、阴影(shadowing)、衰落(fading)、噪声、干扰等因素的变化而发生变化。基于此,发送端的通信装置可以通过一定的方法根据信道状况的不同,选择不同的调制和编码方案(modulation and coding scheme,MCS),以达到一定传输成功概率与较高的传输速率的折中,从而提升无线通信系统整体的吞吐率。
示例性的,发送端的通信装置与接收端的通信装置可以基于一定的信道探测和反馈流程,使得发送端的通信装置获取可以反映信道状况的一些参数(例如,信噪比(signal to noise ratio,SNR)),并根据该参数了解信道状况,进而选择合适的MCS。接收端的通信装置也可以在进行信道探测之后,向发送端的通信装置建议接收端的通信装置所需的MCS,以及接收端的通信装置所需的空间流数(number of spatial streams,NSS)。
多输入多输出(multiple-input multiple-output,MIMO)系统:可以通过用户数量将MIMO系统分为单用户多输入多输出(single-user MIMO,SU-MIMO)系统和多用户多输入多输出(multi-user MIMO,MU-MIMO)系统。相对于MU-MIMO系统,SU-MIMO系统也可以被描述为non-MU-MIMO系统。
SU-MIMO系统:即占用相同时频资源的多个并行空间流发送给同一个用户,可以用于增加一个用户的速率。
示例性的,如图1所示,以SU-MIMO系统为图1所示的天线系统为例,天线系统可以包括天线数为4的接入点(access point,AP)和天线数为2的用户,AP在同一时刻只能向一个用户发送数据。
MU-MIMO系统:即占用相同时频资源的多个并行空间流发送给不同的用户,可以用于增加多个用户的速率。其中,MU-MIMO系统的核心可以是空分多址(space division multiple access,SDMA)技术,即利用相同的时隙、相同的子载波、但不同的天线传送多个用户的数据。SDMA技术通过在空间上区别用户,可以在链路上容纳更多的用户,以提高通信系统容量。
示例性的,如图2所示,以MU-MIMO系统为图2所示的天线系统为例,天线系统可以包括天线数为4的AP和4个天线数为1的用户,AP在同一时刻可以向4个用户发送数据。

在WLAN通信系统中,通信装置与通信装置之间可以通过PPDU中的MPDU传递控制信令、管理信令或数据。

另外,在MPDU帧头的高吞吐率控制字段,通信装置也可以传输一些控制信息。
示例性的,高吞吐率控制字段的高效变种(例如HT变种、VHT变种、HE变种)可以包括聚合控制(aggregated control,A-control)子字段,如图4所示,A-control子字段可以包括一个或N个控制子字段和填充字段;其中,各个控制子字段可以包括比特数为4的控制标识符字段和比特数为可变的控制信息字段,以用于承载1个或N个控制信息,其中,各个控制子字段中,控制标识符字段可以用于指示控制信息的类型。
具体的,对于802.11ax标准,MPDU可以包括HT控制字段(或者也可以描述为A-control子字段),HT控制字段可以包括一个或多个控制标识符字段、每个控制标识符字段对应的控制信息字段、以及填充字段。如图5所示,当控制标识符字段的值为2时,控制信息字段可以为26比特的高效链路自适应(HE link adaptation,HLA)控制子字段。
其中,如图5所示,802.11ax标准中,HLA控制子字段可以包括比特数为1的非请求式MCS反馈(unsolicited MCS feedback,unsolicited MFB)子字段、比特数为1的MCS请求(MCS request,MRQ)子字段、比特数为3的NSS子字段、比特数为4的HE-MCS子字段、比特数为1的双载波调制(dual carrier modulation,DCM)子字段、比特数为8的资源单元分配(resource unit allocation,RU allocation)子字段、比特数为2的带宽(band width,BW)子字段、比特数为3的MCS请求序列指示或部分PPDU参数(MRQ sequence identifier or partial PPDU parameters,MSI/partial PPDU parameters)子字段、比特数为1的发送端波束成形(Tx beamforming)子字段、比特数为1的上行高效基于触发PPDU的MCS反馈(up link HE trigger based PPDU MFB,UL HE TB PPDU MFB)子字段、比特数为1的预留子字段。

需要说明的是,在802.11ax标准中,上述RU allocation子字段的8比特中,可以采用7比特指示具体的RU,采用剩余的1比特指示前述7比特指示的RU适用于主80MHz还是次80MHz。
示例性的,以RU allocation子字段的8比特为B0-B7为例,B0可以用于指示B7-B1指示的RU适用于主80MHz还是次80MHz,例如,可以将B0设置为0指示主80MHz,将B0设置为1指示次80MHz;B7-B1可以通过7比特索引指示具体的RU。

相比于802.11ax标准,802.11be标准或未来Wi-Fi标准可以支持更多的特性和功能, 但是,基于上述对表2的描述,802.11ax标准中已经预先定义了HLA控制子字段的各个子字段的比特数和含义,如果在802.11be标准或未来Wi-Fi标准中继续沿用HLA控制子字段,会存在无法支持更多的特性和功能的技术问题。
例如,802.11be标准或未来Wi-Fi标准可以支持更多的空间流数或者更大的带宽,但是由于802.11ax标准中已经预先定义了HLA控制子字段中的NSS子字段和BW字段的比特数和含义,HLA控制子字段无法支持更多的空间流数或者更大的带宽。
综上,如何合理设计802.11be标准或未来Wi-Fi标准对应的链路自适应控制子字段成为亟待解决的技术问题。
为解决该问题,本申请实施例提供了一种通信方法和装置,其中,第一通信装置生成PPDU,向第二通信装置发送该PPDU;其中,PPDU包括比特数为26的第一字段,第一字段包括比特数为1的非请求式MFB子字段和比特数为1的第一指示信息;其中,当非请求式MFB子字段的取值为第一取值时,第一指示信息用于指示MRQ,当非请求式MFB子字段的取值为第二取值时,第一指示信息用于指示UL EHT TB PPDU MFB。
本申请实施例中,结合非请求式MFB子字段的取值,将MRQ和UL EHT TB PPDU MFB用一比特来指示,相比于802.11ax标准中将MRQ和UL EHT TB PPDU MFB分别用1比特指示,可以节约1比特,进而可以利用该节约出来的1比特支持802.11be标准或未来Wi-Fi标准中更多的特性和功能,使得第一字段在不增加比特数的情况下(即仍为26比特)反馈更多信息。

图9为本申请实施例提供的一种通信方法的流程图,如图9所示,该方法可以包括:
步骤901、第一通信装置生成PPDU。
其中,PPDU可以包括比特数为26的第一字段,第一字段可以包括比特数为1的非请求式MFB子字段和比特数为1的第一指示信息。
其中,当非请求式MFB子字段的取值为第一取值时,第一指示信息可以用于指示MRQ,当非请求式MFB子字段的取值为第二取值时,第一指示信息可以用于指示UL EHT TB PPDU MFB。
一种可能的实现方式中,第一字段具体可位于MAC帧中的A-control字段中。
需要说明的是,第一字段也可以描述为LA控制子字段,第一指示信息也可以描述为 MRQ/UL EHT TB PPDU MFB子字段,具体的,当第一指示信息用于指示MRQ时,第一指示信息也可以描述为MRQ子字段;当第一指示信息用于指示UL EHT TB PPDU MFB时,第一指示信息也可以描述为UL EHT TB PPDU MFB子字段。
例如,当非请求式MFB子字段的取值为0时,第一指示信息可以用于指示MRQ,当非请求式MFB子字段的取值为1时,第一指示信息可以用于指示UL EHT TB PPDU MFB。
具体的,根据上述表2可知,当非请求式MFB子字段的值为1时,UL EHT TB PPDU可以用于指示第一字段提供的信息是否用于UL TB PPDU,MRQ为预留比特;当非请求式MFB子字段的值为0时,MRQ可以用于指示是否为请求式反馈,UL EHT TB PPDU为预留比特;通过将UL EHT TB PPDU子字段和MRQ子字段压缩为1比特,即通过比特数为1的第一指示信息指示UL EHT TB PPDU或MRQ,可以节省比特数。
示例性的,请求式反馈的具体流程可以为:第一通信装置(也可以描述为MFB请求方)可以将MFB请求通过PPDU进行发送,该MFB请求中,非请求式MFB子字段置0,第一指示信息用于指示MRQ且第一指示信息置1。第二通信装置(也可以描述为MFB响应方)收到MFB请求方发送的MFB请求后,可以基于携带MFB请求的PPDU,测量相关MFB参数,并向MFB请求方发送MFB响应,该MFB响应中,非请求式MFB子字段置0且MRQ子字段置0。
可选的,该MFB请求中还包括SU-MIMO/MU-MIMO指示。
例如,以SU-MIMO/MU-MIMO指示为1比特为例,可以通过将该1比特设置为0表示SU-MIMO,设置为1表示MU-MIMO;或者将该1比特设置为1表示SU-MIMO,设置为0表示MU-MIMO。
示例性的,非请求式反馈的具体流程可以为:第一通信装置可以通过PPDU发送非请求式MFB,其中,非请求式MFB子字段置1,第一指示信息用于指示UL EHT TB PPDU MFB,该非请求式MFB可以用于指示PPDU的相应的参数,以使第二通信装置根据接收到的PPDU估计出MFB参数。
其中,PPDU的相应的参数可以包括下述一种或多种:PPDU类型、编码类型、发送端波束成形指示、SU-MIMO/MU-MIMO传输等。
步骤902、第一通信装置向第二通信装置发送PPDU。相应的,第二通信装置接收PPDU。
步骤903、第二通信装置对PPDU进行解析。
基于图9所示的方法,结合非请求式MFB子字段的取值,将MRQ和UL EHT TB PPDU MFB用一比特来指示,相比于802.11ax标准中将MRQ和UL EHT TB PPDU MFB分别用1比特指示,可以节约1比特,进而可以利用该节约出来的1比特支持802.11be标准或未来Wi-Fi标准中更多的特性和功能,使得第一字段在不增加比特数的情况下(即仍为26比特)反馈更多信息。
进一步的,第一字段还可以包括比特数大于或等于3的NSS子字段,其中,NSS子字段用于指示空间流数,该空间流数最大可以为16。
示例性的,以NSS子字段的比特数等于3为例,可以将该比特数的取值0-7分别对应空间流数1-16中的任意8种流数,本申请不予限制。
例如,可以将比特数取值0-7分别对应空间流数1、2、4、6、8、10、12、16;也可以将比特数的取值0-7分别对应空间流数1、3、5、7、9、11、13、16;不予限制。
示例性的,以NSS子字段的比特数等于4为例,可以将该比特数的取值0-15对应空间流数1-16,对于具体的比特值与空间流数对应关系不予限制。一种可能的实现方式中,该比特数取值0-15与空间流数1-16一一对应,即比特值为0,对应空间流数1,比特值为1,对应空间流数2等,在此不一一举例。
需要说明的是,第一字段中,当非请求式MFB子字段置1且UL EHT TB PPDU MFB子字段置0时,或者,当非请求式MFB子字段置0且MRQ子字段置0时,NSS子字段可以用于指示发送给该站点(或者可以描述为发送该反馈的站点)的PPDU时推荐的空间流数;当非请求式MCS反馈置1且UL EHT TB PPDU MFB子字段置1时,NSS子字段可以用于指示该站点发送EHT TB PPDU时推荐的空间流数;其他情况时,NSS子字段预留。
基于上述对NSS子字段的描述,相比于802.11ax标准,本申请实施例中NSS子字段指示的空间流数最大可以为16,可以更好的满足802.11be标准或未来Wi-Fi标准中对空间流数的需求。
进一步的,上述第一字段还可以包括比特数为4的EHT MCS子字段;或者,第一字段还可以包括比特数为6的信噪比SNR子字段。
其中,当第一字段包括比特数为4的EHT MCS子字段时,EHT MCS子字段可以用于指示推荐的EHT MCS,EHT MCS子字段的取值与各个取值对应的EHT MCS可以如下述表4所示:
表4
Figure PCTCN2022093093-appb-000007
其中,当EHT MCS子字段的取值为14或15时,EHT MCS子字段还可以用于指示推 荐使用DCM,即EHT-MCS子字段的取值为0-15时还可以用于指示是否推荐使用DCM。进一步的,当EHT MCS子字段的取值为14时,在BPSK+DCM的基础上,还可以引入重复传输。
需要说明的是,第一字段中,当非请求式MFB子字段置1且UL EHT TB PPDU MFB子字段置0时,或者,当非请求式MFB子字段置0且MRQ子字段置0时,EHT MCS子字段可以用于指示发送给该站点的PPDU时推荐的EHT MCS;当非请求式MFB子字段置1且UL EHT TB PPDU MFB子字段置1时,EHT MCS子字段可以用于指示该站点发送EHT TB PPDU时推荐的EHT-MCS;其他情况时,EHT MCS子字段预留。
其中,当第一字段包括比特数为6的信噪比SNR子字段时,SNR子字段可以为2s补码指示的有符号整数,其中,比特位的最高位取负,其他位取正,例如,100001可以表示:-32+1=-31;SNR子字段表示的有符号整数的范围可以为-32~31,各个有符号整数与信噪比的对应关系可以如下述表5所示:
表5
SNR子字段表示的有符号整数 信噪比(dB)
-32 ≤10
-31 -9
-30 -8
30 52
31 ≥53
基于上述对EHT MCS子字段或SNR子字段的描述,相比于802.11ax标准,本申请实施例中通过将HE-MCS子字段替换成4比特的EHT MCS子字段,或者将HE-MCS子字段替换成6比特的SNR子字段,可以更好的满足802.11be标准或未来Wi-Fi标准中对EHT MCS或SNR的需求。
进一步的,第一字段还可以包括RU allocation子字段;其中,RU allocation子字段的比特数为5;或者,RU allocation子字段的比特数为7;或者,RU allocation子字段的比特数为8;或者,RU allocation子字段的比特数为9。
其中,根据RU的大小,可以将小于242-tone的RU称为小RU(small RU),大于或等于242-tone的RU称为大RU(large RU),一定固定组合的多个RU称为多资源单元(multiple resource unit,MRU)。需要说明的是,大RU支持的组合情况针对OFDMA传输和非OFDMA(也可以描述为non-OFDMA)传输不同,相比于OFDMA传输,non-OFDMA多支持一种996+484+242-tone RU,其他都相同。
示例性的,以带宽为20MHz为例,图10至图12可以为20MHz的子载波分布及RU分布,如图10所示,RU大小可以为26-tone、52-tone、106-tone或242-tone;如图11所示,RU大小可以为26-tone、52-tone或52+26-tone;如图12所示,RU大小可以为26-tone、106-tone或106+26-tone。

又一种示例中,以带宽为160MHz或者80+80MHz为例,整个带宽可以看成两个80MHz的子载波分布的复制,整个带宽可以由一整个2*996-tone RU组成,也可以由26-tone RU、52-tone RU、106-tone RU、242-tone RU、484-tone RU、996-tone RU的各种组合组成。如图20所示,RU大小可以为996+484-tone;如图21所示,RU大小可以为996+484+242-tone。
又一种示例中,以带宽为320MHz或者160+160MHz为例,整个带宽可以看成四个80MHz的子载波分布的复制,整个带宽可以由一整个4*996-tone RU组成,也可以由26-tone RU、52-tone RU、106-tone RU、242-tone RU、484-tone RU、996-tone RU的各种组合组成。如图22所示,RU大小可以为2*996+484-tone;如图23所示,RU大小可以为3*996-tone;如图24所示,RU大小可以为3*996+484-tone。
