Description

传输物理层协议数据单元的方法和装置
本申请要求于2020年6月2日提交中国专利局、申请号为202010491814.5、申请名称为“传输物理层协议数据单元的方法和装置”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
本申请实施例涉及通信领域,尤其涉及一种传输物理层协议数据单元的方法和装置。
背景技术
随着移动互联网的发展和智能终端的普及,数据流量快速增长,用户对通信服务质量的需求也越来越高,电气和电子工程师协会(institute of electrical and electronics engineers,IEEE)802.11ax标准已经难以在大吞吐量、低抖动和低延迟等方面满足用户需求,因此,迫切需要发展下一代无线局域网(wireless local area network,WLAN)技术,即IEEE 802.11be标准。
与IEEE 802.11ax不同,IEEE 802.11be将采用超大带宽,例如240MHz和320MHz,以实现超高传输速率和支持超密用户的场景。并且在超大下还考虑了打孔以及多个RU合并的场景,针对更大的信道带宽,如何设计短训练域(short training field,STF)序列,是一个值得关心的问题。
发明内容
本申请提供一种传输物理层协议数据单元的方法和装置,能够针对更大的信道带宽,设计短训练域序列。
第一方面,提供了一种传输物理层协议数据单元的方法,包括:生成遵循802.11be标准的物理层协议数据单元PPDU,所述PPDU包括短训练域,所述短训练域的频域序列的子载波个数大于2048;在目标信道上发送所述PPDU,其中,所述目标信道的带宽大于或等于160MHz。本申请实施例的方法能够确定更大信道带宽所对应的短训练序列或者说频域序列,可以支持接收端对在更大信道带宽上传输的数据进行自动增益控制。该短训练序列可以基于现有信道带宽的短训练序列得到,并且,通过仿真计算,例如调节参数,可以获得性能较好的短训练序列。短训练域可以基于该短训练序列得到。根据本申请实施例,不仅可以满足实际中的更大信道带宽,且向后兼容,而且通过对参数进行穷举仿真验证了本申请实施例提供的短训练序列,峰均功率值PAPR较小,性能较优,进而提高接收端的自动增益控制电路的估计效果,从而降低接收误码率。
结合第一方面,在第一方面的某些实现方式中,所述目标信道的带宽为240MHz,所述短训练域的频域序列为以下任意一项:

下面将结合附图,对本申请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(wireless local area network,WLAN)通信系统,全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(wideband code division multiple access,WCDMA)系统、通用分组无线业务(general packet radio service,GPRS)、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、未来的第五代(5th generation,5G)系统或新无线(new radio,NR)等。
以下作为示例性说明,仅以WLAN系统为例,描述本申请实施例的应用场景以及本申请实施例的方法。
具体而言,本申请实施例可以应用于无线局域网(wireless local area network,WLAN),并且本申请实施例可以适用于WLAN当前采用的电气与电子工程师协会(institute of electrical and electronics engineers,IEEE)802.11系列协议中的任意一种协议,比如IEEE802.11be(又称为Wi-Fi 7协议)。WLAN可以包括一个或多个基本服务集(basic service set,BSS),基本服务集中的网络节点包括接入点(access point,AP)和站点(station,STA)。
具体地,本申请实施例中发送端或接收端可以是WLAN中用户站点(STA),还可以是用户站点中的芯片或处理系统,该用户站点也可以称为系统、用户单元、接入终端、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理、用户装置或用户设备(user equipment,UE)。该STA可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、具有无线局域网(例如Wi-Fi)通信功能的手持设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。
另外,本申请实施例中的发送端或接收端也可以是WLAN中AP或AP中的芯片或处理系统,AP可用于与接入终端通过无线局域网进行通信,并将接入终端的数据传输至网络侧,或将来自网络侧的数据传输至接入终端。
为便于理解本申请实施例,首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。如图1所示的场景系统可以是WLAN系统,图1的WLAN系统可以包括一个或者多个AP,和一个或者多个STA,图1以一个AP和三个STA为例。AP和STA之间可以通过各种标准进行无线通信。例如,AP和STA之间可以采用单用户多入多出(single-user multiple-input multiple-output,SU-MIMO)技术或多用户多入多出(multi-users multiple-input multiple-output,MU-MIMO)技术进行无线通信。
其中,AP也称为无线访问接入点或热点等。AP是移动用户进入有线网络的接入点, 主要部署于家庭、大楼内部以及园区内部,也可以部署于户外。AP相当于一个连接有线网和无线网的桥梁,其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。具体地,AP可以是带有无线保真(wireless fidelity,WiFi)芯片的终端设备或者网络设备。可选地,AP可以为支持802.11等多种WLAN制式的设备。图2示出了AP产品的内部结构图,其中,AP可以是多天线的,也可以是单天线的。图2中,AP包括物理层(physical layer,PHY)处理电路和媒体接入控制(media access control,MAC)处理电路,物理层处理电路可以用于处理物理层信号,MAC层处理电路可以用于处理MAC层信号。802.11标准关注PHY和MAC部分,本申请实施例关注在MAC和PHY上的协议设计。
其中,STA产品通常为支持802.11系列标准的终端产品,如手机、笔记本电脑等,图3示出了单个天线的STA结构图,实际场景中,STA也可以是多天线的,并且可以是两个以上天线的设备。图3中,STA可以包括物理层(physical layer,PHY)处理电路和媒体接入控制(media access control,MAC)处理电路,物理层处理电路可以用于处理物理层信号,MAC层处理电路可以用于处理MAC层信号。
WLAN系统可以提供高速率低时延的传输,随着WLAN应用场景的不断演进,WLAN系统将会应用于更多场景或产业中,比如,应用于物联网产业,应用于车联网产业或应用于银行业,应用于企业办公,体育场馆展馆,音乐厅,酒店客房,宿舍,病房,教室,商超,广场,街道,生成车间和仓储等。当然,支持WLAN通信的设备(比如接入点或站点)可以是智慧城市中的传感器节点(比如,智能水表,智能电表,智能空气检测节点),智慧家居中的智能设备(比如智能摄像头,投影仪,显示屏,电视机,音响,电冰箱,洗衣机等),物联网中的节点,娱乐终端(比如AR,VR等可穿戴设备),智能办公中的智能设备(比如,打印机,投影仪,扩音器,音响等),车联网中的车联网设备,日常生活场景中的基础设施(比如自动售货机,商超的自助导航台,自助收银设备,自助点餐机等),以及大型体育或音乐场馆的设备等。本申请实施例中对于STA和AP的具体形式不做特殊限制,在此仅是示例性说明。
为了大幅提升WLAN系统的业务传输速率,IEEE 802.11ax标准在现有正交频分复用(orthogonal frequency division multiplexing,OFDM)技术的基础上,进一步采用正交频分多址(orthogonal frequency division multiple access,OFDMA)技术。OFDMA技术支持多个节点同时发送和接收数据,从而实现多站点分集增益。
从802.11a经802.11g、802.11n、802.11ac到802.11ax的演进过程中,可用频段包括2.4吉赫(GHz)和5GHz。随着开放的频段越来越多,802.11所支持的最大信道带宽从20兆赫(MHz)扩展到40MHz再扩展到160MHz。2017年,美国联邦通信委员会(federal communications commission,FCC)开放了一段新的免费频段6GHz(5925-7125MHz),802.11ax标准工作者在802.11ax项目授权申请书(project authorization requests,PAR)中把802.11ax设备工作范围从2.4GHz,5GHz拓展到2.4GHz,5GHz和6GHz。由于新开放的6GHz频段可用带宽更大,可以预见,在802.11ax之后的下一代标准(比如802.11be或Wi-Fi 7)演进中,会支持大于160MHz的信道带宽。
每一代主流802.11协议都是兼容传统站点的。比如最早一代主流WiFi的802.11a帧 结构以前导码开始,包括传统短训练字段(legacy-short training field,L-STF)、传统长训练字段(legacy-long training field,L-LTF)、传统信令域(legacy-signal field,L-SIG)。在之后的802.11及802.11ax,为了兼容传统站点,其帧结构都以传统前导码开始。在传统前导码之后,是每一代新定义的信令字段、短训练字段和长训练字段。其中,将传统前导码之后的短训练字段(short training field,STF)简称为极高吞吐量短训练字段(extremely high throughput-STF,EHT-STF),以区别L-STF。当传输大于20MHz信道带宽时,L-STF是在每20MHz的信道带宽上复制再传输,而这些802.11a之后引入的EHT-STF则针对大于20MHz的信道带宽分别定义为新的序列。例如,802.11ac所定义的STF,即非常高吞吐率-短训练字段(very high throughput-STF,VHT-STF),分别定义有20MHz、40MHz、80MHz和160MHz的序列。同样,802.11ax所定义的高效-短训练字段(high efficiency-STF,HE-STF)也支持最大为160MHz的信道带宽。需要说明的是,本申请实施例中,字段还可以称为域,比如短训练字段还称为短训练域。
协议规定,HE-STF的时域波形包含5个重复周期,主要用来增强多输入多输出(multiple-input multiple-output,MIMO)传输下自动增益控制电路(automatic gain control,AGC)的估计,所以要求序列的峰均功率比(peak to average power ratio,PAPR)越小越好。
如上所述,在802.11ax之后的下一代标准(比如IEEE 802.11be)演进中,会支持大于160MHz的信道带宽,例如240MHz和320MHz,以实现超高传输速率和支持超密用户的场景。在802.11be中,还新增了打孔以及多个RU合并的新特性。因此,需要针对更大的信道带宽以及新的打孔和多RU合并的新特性,设计新的短训练域序列。有鉴于此,本申请实施例提供了一种传输物理层协议数据单元的方法和装置,能够针对更大的信道带宽,新的打孔和多RU合并的新特性,设计短训练域序列。
为便于理解本申请实施例,下面先对本申请涉及到的几个名词或术语进行简单介绍。
1、子载波
无线通信信号都是有限带宽的,利用OFDM技术可以在信道带宽内按照一定频率间隔将带宽分成多个频率分量,这些分量被称为子载波(subcarrier)或tone。子载波的下标为连续的整数,其中,下标为0的子载波对应直流分量,下标为负数的子载波对应低于直流的频率分量,下标为正数的子载波对应高于直流的频率分量。
2、短训练序列
短训练序列的主要用途是进行信号检测、自动增益控制(automatic gain control,AGC)、符号定时和粗频率偏差估计等。针对不同的最大信道带宽,可以定义不同的序列。例如,802.11ax所定义的HE-STF支持最大为160MHz的信道带宽。本申请针对的信道带宽大于160MHz,当然也可以支持160MHz的带宽,可以应用于支持802.11be协议的无线局域网中,因此,为区分,在本申请实施例中,称为EHT-STF。应理解,EHT-STF用于表示应用于802.11be的的短训练字段或短训练域,其具体名称不对本申请实施例的保护范围造成限定。可选的,EHT-STF可以用于改善MIMO传输中的自动增益控制估计。
短训练序列可以基于M序列构建而成。例如,根据标准802.11ax可知,HE-STF的高效短训练序列(high efficiency sequence,HES)是基于M序列,通过复用、相位旋转 和拼接构建而成。M序列是目前CDMA系统中采用的最基本的伪噪声序列(pseudo-noise sequence,PN序列)。M序列是最长线性反馈移位寄存器序列的简称。M序列在802.11ax标准中定义为M={-1,-1,-1,1,1,1,-1,1,1,1,-1,1,1,-1,1}。
应理解,当未来标准定义M序列有其它形式时,也适用于本申请。
需要说明的是,M序列具体名称不对本申请实施例的保护范围造成限定。例如,也可以称为频域序列等。
首先简单介绍一下802.11ax关于HE-STF的短训练序列HES a:b:c的设计,其中a:b:c表示从子载波a开始每隔b个子载波到子载波c。
图4示出了HE-STF由M序列构建的示意图。图4中的图(1)是重复结构。具体来说,20MHz的HE-STF由一个M序列构成;40MHz的HE-STF由2个20MHz的HE-STF(即,2个M序列)拼接而成;同样的,80MHz的HE-STF由4个20MHz的HE-STF拼接而成的。为了保证HE-STF在时域上包含5个重复周期,以及使得HE-STF的PAPR尽可能的小,可以采用额外的参数值和旋转因子来调整优化,如图4中的图(2)。具体来说,20MHz的HE-STF由一个M序列构成;40MHz的HE-STF由2个20MHz的HE-STF(即,2个M序列)乘以旋转因子C之后拼接而成;同样的,80MHz的HE-STF由4个20MHz的HE-STF乘以旋转因子之后拼接而成的。同时,每2个M序列之间需要插入一个参数值A,以保证HE-STF在时域上包含5个重复周期。例外的是,OFDM调制方式要求直流子载波必须为0。因此,通过优化这些A和C可以使得HE-STF的PAPR达到最小。如图4中的图(2),旋转因子C可以包括{c 1,c 2,c 3,c 4,……},参数值A可以包括{a 1,a 2,a 3,a 4,……}。本文将这些旋转因子和参数值统称为“参数集”。
802.11ax定义了四种帧结构,包括:高效率单用户物理层协议数据单元(high efficiency single-user physical layer protocol data unit,HE SU PPDU)、高效率多用户物理层协议数据单元(high efficiency multi-user physical layer protocol data unit,HE SU PPDU)、高效率扩展范围单用户物理层协议数据单元(high efficiency extended range single-user physical layer protocol data unit,HE ER SU PPDU)、高效率触发物理层协议数据单元(high efficiency trigger based physical layer protocol data unit,HE TB PPDU)。具体的,上述帧结构可以进一步分为两类,一类称为非HE TB PPDU,另一类即为HE TB PPDU。802.11ax根据不同帧结构,定义有两种周期长度的HE-STF,分别是0.8μs和1.6μs,其中,用于非HE TB PPDU的HE-STF的周期长度为0.8μs,子载波间隔为16个,用于HE TB PPDU的HE-STF的周期长度为1.6μs,子载波间隔为8个。另外,802.11ax支持的信道带宽有20MHz,40MHz,80MHz和160MHz一共4种。每一种带宽和长度对应一个HE-STF,所以HE-STF的频域值HES a:b:c一共有8种。
下面分别从长度为0.8μs和1.6μs两种情形下,介绍优化后的不同信道带宽的频域序列。
情形一、0.8μs的HE-STF的频域序列
(1)信道带宽为20MHz,0.8μs的HE-STF,也可以称为STF1x20MHz,一共有256个子载波,下标(或索引index)范围从-127到128。其中,下标为0的子载波对应直流分量,下标为负数和正数的子载波分别对应低于和高于直流的频率分量。
其中,STF1x20MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000067
其中,HES -112:16:112表示20MHz的HE-STF频域序列,具体地,下标为-112、-96、-80、-64、-48、-32、-16、0、16、32、48、64、80、96、112的子载波在频域上的值。HES 0=0,其它子载波在频域上的取值均为0。其它子载波,表示在-127到128的下标范围,除了下标为-112、-96、-80、-64、-48、-32、-16、0、16、32、48、64、80、96、112的子载波之外,其余下标的子载波。
上述公式展开为:
Figure PCTCN2021096105-appb-000068
因此,下标为-112、-96、-80、-64、-48、-32、-16、0、16、32、48、64、80、96、112的子载波在频域上的值分别为:
Figure PCTCN2021096105-appb-000069
需要说明的是,在本文中,公式中涉及到类似于HES -112:16:112的表达,其所要表达的含义是相似的,为简洁,后续不再赘述。
还需要说明的是,在本文中,此后的公式描述中,如未明确标出,其它下标的子载波在频域上的值均为0,为简洁,后续不再赘述。
需要说明的是,下标还可以称为子载波索引,比如下标为0的子载波,还可以称为索引为0的子载波。
(2)信道带宽为40MHz,0.8μs的HE-STF,也可以称为STF1x40MHz,一共有512个子载波,下标范围从-255到256,
其中,STF1x40MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000070
其中,HES -240:16:240表示40MHz的HE-STF频域序列。
(3)信道带宽为80MHz,0.8μs的HE-STF,也可以称为STF1x80MHz,一共有1024个子载波,下标范围从-511到512,
其中,STF1x80MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000071
其中,HES -496:16:496表示80MHz的HE-STF频域序列。
(4)信道带宽为160MHz,0.8μs的HE-STF,也可以称为STF1x160MHz,一共有2048个子载波,下标范围从-1023到1024,
其中,STF1x160MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000072
其中,HES -1008:16:1008表示160MHz的HE-STF频域序列。
情形二、1.6μs的HE-STF的频域序列
(1)信道带宽为20MHz,1.6μs的HE-STF,也可以称为STF2x20MHz,一共有256个子载波,下标范围从-127到128,
其中,STF2x20MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000073
HES 0=0,其它子载波在频域上的取值均为0。
(2)信道带宽为40MHz,1.6μs的HE-STF,也可以称为STF2x40MHz,一共有512个子载波,下标范围从-255到256,
其中,STF2x40MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000074
HES ±248=0。
其中,HES -248:8:248表示40MHz的HE-STF频域序列。
(3)信道带宽为80MHz,1.6μs的HE-STF,也可以称为STF2x80MHz,一共有1024个子载波,下标范围从-511到512,
其中,STF2x80MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000075
HES ±504=0。
其中,HES -504:8:504表示80MHz的HE-STF频域序列。
(4)信道带宽为160MHz,1.6μs的HE-STF,也可以称为STF2x160MHz,一共有2048个子载波,下标范围从-1023到1024,
其中,STF2x160MHz可以用如下公式表示:
Figure PCTCN2021096105-appb-000076
HES ±8=0,HES ±1016=0。
其中,HES -1016:8:1016表示160MHz的HE-STF频域序列。
以上公式中,
Figure PCTCN2021096105-appb-000077
在复平面的几何意义是将某个值逆时针旋转45°,并保持能量归一。同理,
Figure PCTCN2021096105-appb-000078
是将某个值逆时针旋转225°。由此,基于M序列,得到了不同信道带宽下HE-STF,并保证达到了优化的PAPR。
3、峰均功率比
峰均功率比(peak to average power ratio,PAPR),可以指一个符号内,连续信号瞬间功率峰值与信号功率平均值之比。可以用如下公式表示:
Figure PCTCN2021096105-appb-000079
其中,X i,表示一组序列的时域离散值;max(X i 2),表示时域离散值平方的最大值;mean(X i 2),表示时域离散值平方的平均值。
OFDM系统具有高PAPR的缺点,尤其是在大带宽下,更多的子载波导致更为严重的PAPR,高PAPR将会导致信号非线性失真,降低系统性能,所以在设计序列时,要求序列的PAPR越小越好。
4、信道打孔
随着信道带宽越来越大,例如,在802.11ax标准中最大支持160MHz,但是,在实 际部署中,由于部分信道收到干扰或有其他设备占用等原因,160MHz信道可能存在部分信道不可用,在实际传输中,很难采用完整的160MHz信道进行通信,为此,802.11ax提出了打孔模式,具体是以信道带宽为20MHz为粒度的信道打孔技术来缓解该问题,从而可以利用160MHz信道中的可用信道来进行通信,提高信道的利用率。
下面对802.11be或者是未来任一代WLAN标准(比如Wi-Fi 8)中可能的信道打孔方式进行举例说明,需要说明的是,在下面的举例中,以一个“1”表示一个20MHz的信道带宽,未被打孔,对应256个子载波未被打孔,以及,一个“0”表示一个20MHz的信道被打孔,被打开的20MHz信道可以简称打孔信道,也可以理解为被占用的信道。
(1)240MHz信道带宽的信道打孔方式,240MHz信道包括12个20MHz信道,12个“0”或“1”的取值依次对应这12个20MHz信道。可选的,这12个20MHz信道频率从低到高依次对应从左到右的12个“0”或“1”。
方式1:[1 1 1 1 1 1 1 1 1 1 1 1],对应的信道带宽为240MHz,对应有3072个子载波。
方式2:[0 0 1 1 1 1 1 1 1 1 1 1],对应的可用信道带宽为200MHz,也可以理解剩余的信道带宽为200MHz。
方式3:[1 1 0 0 1 1 1 1 1 1 1 1],对应的可用信道带宽为200MHz。
方式4:[1 1 1 1 0 0 1 1 1 1 1 1],对应的可用信道带宽为200MHz。
方式5:[1 1 1 1 1 1 0 0 1 1 1 1],对应的可用信道带宽为200MHz。

方式10:[1 1 1 1 1 1 1 1 0 0 0 0],对应的可用信道带宽为160MHz。
(2)320MHz信道带宽的信道打孔方式,320MHz信道包括16个20MHz信道,16个“0”或“1”的取值依次对应这16个20MHz信道。可选的,这16个20MHz信道频率从低到高依次对应从左到右的16个“0”或“1”。
具体的,320MHz信道带宽的信道打孔方式可以分为两种:一种为兼容240MHz信道打孔模式,另一种为不兼容240MHz信道打孔模式。其中,“兼容”是指将320MHz信道带宽通过信道打孔形成240MHz后,再基于可用信道带宽,即打孔后形成的240MHz信道继续打孔。

5、资源块分布(RU allocation)
资源块分布也可以理解为信道带宽中的子载波分布(tone plan),不同的信道带宽可 以对应的不同的tone plan。在应用OFDMA及多用户多入多出(multiple user multiple input multiple output,MU-MIMO)技术时,IEEE 802.11ax协议规定信道带宽中的子载波划分为若干个资源块(resource unit,RU)。IEEE 802.11ax协议规定对于20MHz、40MHz、80MHz和160MHz的信道带宽划分成多种类型资源块,其中包括26子载波资源块、52子载波资源块、106子载波资源块、242子载波资源块(20MHz带宽内最大资源块)、484子载波资源块(40MHz带宽内最大资源块)、996子载波资源块(80MHz带宽内最大资源块)、和1992子载波资源块(160MHz带宽内最大资源块)。每个RU由连续的子载波组成,比如26子载波资源块是由26个连续的子载波资源块组成。需要说明的是,不同的总带宽所能支持的RU的种类和数量不相同,但是在同一带宽下,可以支持混合类型的资源块。
图5a示例性示出了802.11be中80MHz带宽下的tone plan的示意图。其中,左边带子载波以及右边带子载波位于传输频带的边缘处,其作为防护子载波,以减轻传输滤波对数据和导频子载波的影响。各带宽中的子载波包括:数据子载波,导频子载波,以及未使用的子载波(unused subcarriers)。未使用的子载波既不用于传输数据也不用于传输导频信号,未使用的子载波包括:直流子载波(DC subcarriers),保护子载波(guard subcarriers)以及空子载波(null subcarriers)。保护子载波还可以包括左边带子载波和右边带子载波。直流子载波是内容为空(empty)的子载波(即不携带数据或信息的子载波),移动设备用之以定位OFDM频带的中心。。左边带子载波、右边带子载波、直流子载波、空子载波还可以统称为RU间残留子载波(leftover tone),大的RU子载波个数和对应其中可容纳的多个小RU以及小RU间残留子载波个数总和相同。
OFDMA系统中,RU可以包括但不限于:
(1)连续26个子载波组成的RU,包括:24个数据子载波和2个pilot导频子载波;
(2)连续52个子载波组成的RU,包括:48个数据子载波和4个pilot导频子载波;
(3)连续106个子载波组成的RU,包括:102个数据子载波和4个pilot导频子载波;
(4)连续242个子载波组成的RU,包括:234个数据子载波和8个pilot导频子载波;
(5)连续484个子载波组成的RU,包括:468个数据子载波和16个pilot导频子载波;
(6)连续996个子载波组成的RU,包括:980个数据子载波和16个pilot导频子载波。
示例性的,在802.11ax中,一个用户可以被分配(1)至(6)中的一个RU,在802.11be或者是未来的标准中支持多RU模式,也就是说,一个用户可以被分配多个RU(Multiple Resource units,MRU),MRU模式包括但不限于如下几种:
(7)RU52+RU26:该分配方式可以理解为将连续26个子载波组成的RU(记为26-tone RU)和连续52个子载波组成的RU(记为52-tone RU)分配给用户,如图5b所示为RU52+RU26的tone plan示意图(其中,阴影部分即为用户分配的RU)。可选的, RU52+RU26中的52-tone RU和26-tone RU位于同一个20MHz信道中,比如图5b所示的从左往右的第一个20MHz信道中的,第三个52-tone RU与第一行的第8个26-tone RU合并为MRU分配给一个用户。
(8)RU106+RU26:该分配方式可以理解为将连续26个子载波组成的RU(记为26-tone RU)和连续106个子载波组成的RU(记为106-tone RU)分配给用户,如图5c所示为RU106+RU26的tone plan示意图。可选的,RU106+RU26中的106-tone RU和26-tone RU位于同一个20MHz信道中,比如图5c所示的从左往右的第一个20MHz信道中的,第一个106-tone RU与第一行的第五个26-tone RU合并为MRU分配给一个用户。
(9)RU242+RU484:该分配方式可以理解为将连续242个子载波组成的RU(记为242-tone RU)和484个子载波组成的RU(记为484-tone RU)分配给用户,如图5d~5g所示为RU242+RU484的tone plan示意图。
应理解,160MHz的tone plan可以看作2个80MHz的tone plan组成。240MHz的tone plan可以看作3个80MHz的tone plan组成。320MHz的tone plan可以看作4个80MHz的tone plan组成,此处不再赘述。需要说明的是,如果在一个80MHz分段中,使用了信道打孔模式,那么就使用OFDMA的tone plan,如果是非穿孔的80MHz的分段,那么就使用Non-OFDMA的tone plan。

下面将结合附图详细说明本申请提供的技术方案。本申请实施例可以应用于多个不同的场景下,包括图1所示的场景,但并不限于该场景。示例性地,对于上行传输,STA可以作为发送端,AP可以作为接收端;对于下行传输,AP可以作为发送端,STA可以作为接收端;对于其他传输场景,例如,AP和AP之间的数据传输,其中一个AP可以作为发送端,另一个AP可以作为接收端;又例如,STA和STA之间的上行传输,其中一个STA可以作为发送端,另一个STA可以作为接收端。因此,下面按照发送端和接收端对本申请实施例进行描述。
图6是本申请实施例提供的传输物理层协议数据单元的方法的示意性流程图。图6所示的方法可以包括如下步骤。
步骤101,发送端生成物理层协议数据单元PPDU,该PPDU包括短训练域,该短训练域的频域序列的长度大于第一长度,该第一长度为在带宽为160MHz的信道上传输的PPDU的短训练域的频域序列的长度。
步骤102,发送端在目标信道上发送该PPDU,其中,该目标信道的带宽大于或等于160MHz。
相应地,接收端在目标信道上接收PPDU。
步骤103,接收端解析PPDU。
接收端可基于PPDU中的短训练域进行信号检测、自动增益控制(automatic gain control estimation,AGC)估计、符号定时和粗频率偏差估计等,关于具体的解析方式和应用可参考现有描述,对此不做限定。
上述短训练域也可以称为短训练字段,下文统一用短训练域表示。
在本申请实施例中,为区分传统短训练字段,将目标信道的带宽对应的短训练字段用(extremely high throughput-STF,EHT-STF)表示。应理解,EHT-STF用于应用于802.11be协议中的短训练字段,其具体名称不对本申请实施例的保护范围造成限定。
EHT-STF是通过EHT-STF的频域序列获得的,如EHT-STF由EHT-STF的频域序列或者说频域值经过IFFT变换后得到的,本申请中为描述方便,将EHT-STF的频域序列简称为EHTS。应理解,EHTS仅是一种命名,并不对本申请实施例的保护范围造成限定,例如也可称为频域序列。
在本申请实施例中,用第一长度表示带宽为160MHz对应的频域序列的长度。短训练域的频域序列长度大于第一长度,换句话说,EHT-STF的频域序列的长度大于信道带 宽为160MHz的HE-STF的频域序列的长度。例如,160MHz的HE-STF可以由2个80MHz的HE-STF乘以旋转因子之后拼接而成的,240MHz的EHT-STF可以由3个80MHz的HE-STF乘以旋转因子之后拼接而成的,或者,240MHz的EHT-STF也可以由320MHz的EHT-STF穿孔而成的(例如,可以将320MHz的EHT-STF打掉80MHz的EHT-STF从而形成240MHz的EHT-STF),320MHz的EHT-STF可以由4个80MHz的HE-STF乘以旋转因子之后拼接而成的,故EHT-STF的频域序列的长度大于信道带宽为160MHz的HE-STF的频域序列的长度。
短训练域的频域序列长度大于第一长度,或者也可以理解为,EHT-STF的频域值的数量大于160MHz的HE-STF的频域值的数量,如240MHz带宽共有3072个子载波,那么该3072个子载波对应3072个频域值,160MHz带宽共有1024个子载波,那么该1024个子载波对应1024个频域值,因此,EHT-STF的频域值的数量大于160MHz的HE-STF的频域值的数量。
短训练域的频域序列长度大于第一长度,或者也可以理解为,EHT-STF对应的子载波标号的数量大于160MHz的HE-STF对应的子载波标号的数量,如240MHz的EHT-STF对应的短训练序列可以表示为EHTS -1520:16:1520,160MHz的HE-STF对应的短训练序列可以表示为HES -1008:16:1008,那么可以看出EHT-STF对应的子载波标号的数量大于160MHz的HE-STF对应的子载波标号的数量。
在本申请实施例中,序列长度表示序列中元素组成的长度,例如,序列1为:{0,1,-1,1},那么该序列1的长度为4;又如,序列2为:{0,1,-1,1,1,1,1},那么该序列2的长度为7,且可以看出,序列2的长度大于序列1的长度。又如,假设160MHz的HE-STF对应的频域序列长度为2048,那么第一长度为2048,换句话说,EHT-STF的频域序列长度大于2048。
目标信道的带宽大于或等于160MHz。
可选的,目标信道的带宽也可以为大于或等于160MHz的任何带宽,例如,目标信道的带宽为160MHz、200MHz、240MHz、280MHz、或320MHz等等。
本申请实施例的针对目标信道的EHT-STF,可以是通过仿真计算得到。例如,发送端可以基于协议规定的序列(例如IEEE 802.11ax中的HE-LTF序列),采用相应公式计算得到。又如,发送端可以基于已存储的或者新生成的序列,采用相应公式计算得到,本申请实施例对此不做限定。
根据本申请实施例,考虑到向后兼容,以现有信道带宽的STF对应的短训练序列HES,如,HE-STF对应的短训练序列HES为基础,设计更大信道带宽的短训练序列,如EHT-STF对应的短训练序列EHTS。
本申请实施例的传输PPDU的方法,能够确定更大信道带宽所对应的短训练序列或者说频域序列,可以支持接收端对在更大信道带宽上传输的数据进行自动增益控制。该短训练序列可以基于现有信道带宽的短训练序列得到,并且,通过仿真计算,例如调节参数,可以获得性能较好的短训练序列。短训练域可以基于该短训练序列得到。根据本申请实施例,不仅可以满足实际中的更大信道带宽,且向后兼容,而且通过对参数进行穷举仿真验证了本申请实施例提供的短训练序列,峰均功率值PAPR较小,性能较优, 进而提高接收端的自动增益控制电路的估计效果,从而降低接收误码率。
并且,本申请实施例提供的EHTS,还考虑了更大信道带宽中的打孔模式,且验证了本申请实施例EHTS在打孔模式下的性能较好,PAPR较小。针对上行传输,本申请实施例提供的EHTS,还考虑了更大带宽下的多RU合并等情况的性能,在更大带宽下的多RU合并传输的情况下,其PAPR也较小。因此,本申请实施例提供的EHTS,能够适应802.11be协议中更大的信道带宽,新的打孔模式和多RU合并等新特性,且性能较优,可以支持802.11be中的上行或下行传输。下文以目标信道的带宽为240MHz、320MHz这两个示例为例,进行示例性说明。此外,EHT-STF可以包括多个周期,每个周期的时间长度可以为0.8μs或1.6μs。其中,非EHT TB PPDU的EHT STF,也可以称为STF1x,其频域序列的周期长度为0.8μs。EHT TB PPDU的EHT STF,也可以称为STF2x,其频域序列的周期长度为1.6μs。
为简洁,在本申请实施例中,将每个周期的时间长度记为周期长度。在本申请实施例中,以周期长度为0.8μs、1.6μs这两种场景,说明目标信道的带宽的EHT-STF的频域序列。在本申请实施例中,参考信道的周期长度,即表示在参考信道上传输短训练域的频域序列的周期长度,下文不再赘述。
考虑到针对不同的目标信道的带宽和不同的周期长度,可以分别设计对应的EHT-LTF。因此,下面分不同情况详细介绍本申请实施例的方法。
情况一和情况二是针对240MHz信道带宽的EHT-STF。在阐述240MHz信道带宽的EHT-STF之前,首先介绍240MHz的子载波分配图样(tone plane)。如前所述,802.11ax规定的80MHz信道带宽的tone plane为一共有1024个子载波,下标范围从-511到512,其中,在带宽左右边缘分别有12和11个保护子载波(guard tone)。一个示例中,本申请实施例所设计的240MHz的信道带宽的tone plan为3个80MHz的tone plane拼接在一起,即3个80MHz的左右边缘子载波和各自中间的自流子载波均保留。这样,240MHz带宽共有1024×3=3072个子载波,左右边缘分别有12个和11个保护子载波,带宽中间有5个直流子载波。
情况一、目标信道的带宽为240MHz、参考信道的周期长度为0.8μs。
本申请实施例将240MHz带宽、周期长度为0.8μs的EHT-STF的频域序列记作STF1x240MHz,其中,记STF1x240MHz为EHTS -1520:16:1520,STF1x240MHz可以通过下列多种方式构造。
