  • the reassembled RUs corresponding to the reversed VRUs among the converted N VRUs are reversed end-to-end to obtain N PRUs including discrete subcarriers. For example, if in block 401 the subcarriers of the VRU whose RU index is odd are reversed, then in block 404 the subcarriers of the recombined RUs whose RU index is odd are reversed. If in block 401 the subcarriers of the VRU whose RU index is even are reversed, then in block 404 the subcarriers of the recombined RUs whose RU index is even are reversed. Thus, the impact of the transformation in block 401 on the original RU partition can be recovered.

  • the N RU segments in the tone PRU all come from N different 996-tone VRUs. From the perspective of frequency, every N adjacent subcarriers on the first bandwidth come from different N 996-tone PRUs.
  • the optional step of inverting the subcarriers is firstly performed when determining the PRU, the corresponding 242-tone PRUs in each recombined 996-tone PRU are respectively reversed. Therefore, the impact of the above optional steps on subcarrier division is eliminated.

  • the transmitting end device can be allowed to transmit data with greater transmission power.
  • By evenly distributing discrete sub-carriers segment by segment on the bandwidth it can be ensured that data transmission will not cause a large PAPR increase due to discretization of the VRU. Therefore, the technical solution of the present disclosure can make full use of bandwidth resources and improve system efficiency.

Abstract

本公开的实施例提供了用于通信的方法、设备、存储介质和程序产品。在本公开的通信方法中，基于第一带宽的子载波规划发送或接收物理层协议数据单元(PPDU)。子载波规划包括物理资源单元(PRU)，并且该PRU由离散子载波组成。本公开的实施例通过对原始的名义RU进行处理，以获得由离散子载波组成的PRU。离散后的PRU的子载波可以均匀分布在更大带宽上，并且不改变原始名义RU的子载波划分。此外，在保证数据传输不因子载波的离散而产生较大PAPR的同时，能够使发射端以更大的发射功率进行通信。

Description

用于通信的方法、设备、存储介质和程序产品 技术领域
本公开的实施例主要涉及通信领域、尤其涉及用于子载波规划的方法、设备、存储介质和程序产品。
背景技术
无线局域网(Wireless Local Area Network,WLAN)技术从802.11a/g、802.11n、802.11ac、802.11ax标准发展到如今的802.11be标准，已历经多代演变。伴随而来的是数据吞吐量的不断提升，因而，802.11ax标准也被称为高效率(High Efficiency,HE)无线标准，802.11be标准也可以称为极高吞吐量(Extremely High Throughput，EHT)无线标准。
在带宽配置方面，目前802.11ax标准支持如下带宽配置：20MHz、40MHz、80MHz、160MHz及80+80MHz，其中，160MHz与80+80MHz带宽配置的区别在于前者为连续频带，而后者的两个80MHz间可以分离。802.11be标准将支持更大更灵活的带宽配置，诸如240MHz/160+80MHz、320MHz/160+160MHz等。随着带宽的增加，通信设备的最大发射功率也相应增大。通信设备的最大发射功率和最大功率谱密度受到各国各地相关法规的限制。相比最大发射功率，对最大功率谱密度的限制更为严格，而所允许的最大发射功率通常更多地受到功率谱密度的限制。在一定带宽下，为了满足最大功率谱密度的限制，通信设备常常只能以低于最大发射功率的功率通信。

本申请实施例的技术方案可以应用于无线局域网(Wireless Local Area Networks，简称WLAN)系统，还可以应用于其他制式的通信系统，例如可以是：长期演进(Long Term Evolution，简称LTE)系统、5G系统以及未来的其他通信系统。以WLAN系统为例，站点(Station，简称STA)和接入点(Access Point，简称AP)是WLAN系统的基本组成设备。其中，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，典型覆盖半径为几十米至上百米，当然，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WiFi(英文：Wireless Fidelity,中文：无线保真)芯片的设备，例如，为带有WiFi芯片的终端设备或者网络设备。可选地，AP可以为支持802.11ax制式的设备；可选地，该AP也可以为支持802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式的设备，进一步的，该AP也可以为支持802.11be以及支持未来其他802.11标准的WLAN制式的设备。本申请实施例对AP所支持的制式类型并不做限定。
STA在WLAN系统中一般为终端设备。STA可以是移动的，也可以是固定的，其是无线局域网的最基本组成设备。STA可以是无线通讯芯片、无线传感器或无线通信终端，例如，支持WiFi通讯功能的移动电话、支持WiFi通讯功能的平板电脑、支持WiFi通讯功能的机顶盒、支持WiFi通讯功能的智能电视、支持WiFi通讯功能的智能可穿戴设备、支持WiFi通讯功能的车载通信设备和支持WiFi通讯功能的计算机。同样的，STA可以为支持802.11ax制式的设备，STA也可以为支持802.11ac、802.11n、802.11g、802.11b及802.11a等多种WLAN制式的设备。进一步的，STA也可以为支持802.11be以及支持未来其他802.11标准的WLAN制式的设备。本申请实施例对STA支持的制式类型并不做限定。
在本文中使用的术语“包括”及其类似用语应当理解为开放性包含，即“包括但不限于”。除非特别申明，术语“或”表示“和/或”。术语“基于”表示“至少部分地基于”。术语“示例实施例”和“某些实施例”表示“至少一个示例实施例”。术语“第一”、“第二”等等可以指代不同的或相同的对象。下文还可能包括其他明确的和隐含的定义。
IEEE 802.11是当前主流的无线接入标准之一，近十多年来已经获得了极其广泛的商业应用。通信设备可以在一定的带宽上传输数据，其中可以按照预定的子载波规划(Tone Plan)来布置带宽中的资源。以802.11be标准为例，其定义了基于连续资源单元(Resource Unit，RU)的子载波规划。图1A示出了针对20MHz带宽的基于连续RU的子载波规划的示意图。如图1A所示，当带宽为20MHz时，整个带宽可以由一个242-tone RU组成，也可以由诸如26-tone RU、52-tone RU、106-tone RU等更小RU的各种组合组成。
图1B示出了针对40MHz带宽的基于连续RU的子载波规划的示意图。如图1B所示，当带宽为40MHz时，整个带宽可以由一个484-tone RU组成，也可以由26-tone RU、52-tone RU、106-tone RU、242-tone RU等更小RU的各种组合组成。40MHz带宽的子载波规划可被视为相当于20MHz带宽的子载波规划的复制。
图1C示出了针对80MHz的基于连续RU的子载波规划的示意图。如图1C所示，当带宽为80MHz时，整个带宽由4个242-tone RU为单位的RU组成。整个带宽可以由一个996-tone RU组成，也可以由26-tone RU、52-tone RU、106-tone RU、242-tone RU、484-tone RU等更小RU的各种组合组成，其中，484L、484R分别表示单个484-tone RU的左半部分和右半部分，每一部分分别包含242个子载波。
其他带宽配置也可采用类似的子载波规划。例如，当带宽为160MHz或者80+80MHz时，相应的子载波规划可被视为两个80MHz的子载波规划的复制，即，整个带宽可以由一个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等更小RU的各种组合组成。当带宽为240MHz或者160+80MHz时，相应的子载波规划可被视为三个80MHz的子载波分布的复制。当带宽为320MHz或者160+160MHz时，相应的子载波规划可被视为四个80MHz的子载波规划的复制。
以上各种子载波规划均以242-tone RU为单位，示意图的左侧对应于最低频率，并且右侧对应于最高频率。从左到右将242-tone RU编号为第一RU、第二RU、第三RU、第四RU…第十六RU。应当注意，在数据字段中，至多存在16个242-tone RU与16个20MHz信道按照频率从低到高一一对应。
除了上述几种RU，在802.11be标准中还引入了如下RU：

在上述带宽配置中，单个RU由连续子载波组成，也被称为连续RU或名义RU。除了用于传输数据的RU之外，通常还包括保护(Guard)子载波、空子载波、直流(Direct Current，DC)子载波等。应当理解，资源单元是相对概念，其尺寸取决于所包含的子载波(tone)的数目。就带宽层面而言，26-tone RU大致对应于2MHz,52-tone RU大致对应于4MHz,106-tone RU大致对应于8MHz，242-tone RU大致对应于20MHz。根据加法或倍数关系可以类似得到其他RU的尺寸，在此不再进行赘述。
对于传统的名义RU而言，其包括在频域上连续分布的数据(Data)子载波和导频(Pilot)子载波。数据子载波用于承载来自上层的数据信息，而导频子载波传递固定值，以用于接收端设备进行相位估计、相位纠正等目的。分布在20MHz带宽上的名义RU包含256个子载波，索引值为[-128,…,0,…,127]。表1示出了20MHz的各种带宽配置的RU索引和子载波范围，其中RU#标识RU索引，[a,b]代表相应RU的子载波范围为从索引a到索引b，包含a和b本身，{x,y,…}表示相应索引指代导频子载波，{}中元素的数目表示导频子载波的数目。

应当理解，除严格意义的连续RU之外，由两个连续13-tone组成的26-tone RU，由两个连续242-tone(484L和484R)组成的484-tone RU，由两个连续498-tone(996L和996R)组成的996-tone RU可以被称作广义的连续RU。对于n×996-tone RU的子载波范围，当带宽为80MHz时，996-tone RU的的子载波范围为：[-500:-3,3:500]。当带宽更大时，n*996-tone RU的子载波范围可以复用导频子载波的公式。对于多RU，其子载波范围和导频索引为组成该多RU的各个RU的子载波范围和导频索引的集合。
当通信设备利用WLAN技术发送数据时同时受到最大发射功率和最大功率谱密度的限制。例如，美国联邦通信委员会近期颁布了关于6GHz频谱的相关法规，其中定义了针对室内低功耗(Low Power Indoor,LPI)的通信方式。根据该法规，AP的最大功率被限制为36dBm，最大功率谱密度被限制为5dBm/MHz。对于STA，其最大功率被限制为24dBm，并且最大功率谱密度被限制为-1dBm/MHz。相比最大功率，对最大功率谱密度的限制更为严格，并且所 允许的最大功率通常也更多地受功率谱密度的影响。随着发送带宽的增加，通信设备的最大发射功率也相应增大。如下表3所示，当带宽为320MHz时，发射功率才达到上述法规所规定的最大功率。对于相对较小的带宽和RU，在功率谱密度受限的场景中，通信设备常常只能以远低于最大功率的功率发送数据，这将极大地影响传输速率和距离。

为了解决这些问题，根据本公开的示例实施例，提供了一种改进的方案，其利用由离散子载波形成的物理资源单元(Physical Resource Unit，PRU)在比连续RU更大的带宽上传输数据。这样，使发射端设备能够以更大的发射功率传输数据。此外，由于离散后的子载波逐段地均匀分布在整个带宽上，从而保证了数据传输不会因为对VRU的子载波进行离散而引起较大的PAPR增加。同时，上述子载波划分方案可使每个用户对应的LTF(Long Training field)字段具有较低的PAPR。基于这样的方式，本公开的技术方案能够充分利用带宽资源，提高了系统效率。
下文将参考附图2至7来具体讨论本公开的示例实施例。

本公开的第一实现方式
根据上文针对当前带宽配置和子载波资源划分的描述，对于相同大小的资源单元RU，导频子载波在各个资源单元RU中的相对位置不一定相同。如果直接将一个名义资源单元RU均匀离散在更大带宽上，则部分子载波可能会被映射到原导频子载波的位置，部分导频子载波也可能被映射到原数据子载波的位置，显然是不利于通信质量和数据传输的。
根据本公开的示例实施例，提供了一种改进的通信机制，其基于特定的子载波规划，利用包括离散子载波的物理资源单元PRU来传输PPDU，PRU与VRU存在映射关系。该机制可以涉及如图2中所示的接入点210以及站点STA 220。
下面将参考图3来描述重组物理资源单元PRU的示意图。
如图3所示，以第一带宽为80MHz为例，其可以包含虚拟资源单元VRU，例如，4个242-tone VRU 311-314，其中根据子载波规划，242-tone VRU 311和313的导频子载波在各自的RU中具有相同的位置，242-tone VRU 312和314的导频子载波在各自的RU中具有相同的位置。在实践中，这4个242-tone VRU 311-314可以分别分配给一个或多个用户同时进行上行正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)传输。
在步骤1，将该组VRU 311-314中的部分VRU的子载波在频域上首尾颠倒，从而得到VRU 311’-314’。作为示例，可以将242-tone RU 311和313进行首尾颠倒。替代地，作为另一示例，也可以将242-tone RU 312和314进行首尾颠倒。在图3的示例中，针对242-tone RU312和314的子载波进行逆序。经首尾颠倒后，242-tone VRU 311’-314’的导频子载波在其各自的RU中具有相同的相对位置。
在一些示例实施例中，在经过步骤1的首尾颠倒之后，可以进一步将VRU 311’-314’中的一部分连续子载波在频域上进行首尾颠倒。例如，242-tone VRU 311’-314’分别由两个106-tone VRU组成，通过将每个242-tone VRU 311’至314’中的一个106-tone VRU的子载波首尾颠倒，可以使VRU 311’-314’中的导频子载波的分布更加均匀。
在步骤2，将各个242-tone VRU 311’至314’中的子载波进行索引并分为N个RU片段，N为第一带宽对应的VRU的数目，其中第一RU片段为{1，5，9，…，241},第二RU片段为{2，6，10，…，242}，第三RU片段为{3，7，11，…，239}，第四RU片段为{4，8，12，…，240}。
在步骤3，将来自不同的242-tone VRU 311’-314’的N个RU片段组成N个重组RU。换言之，每个重组RU包括分别来自不同的VRU 311’-314’的N个片段，并且在频域上每N个连续子载波对应于不同的242-tone VRU 311’-314’。基于步骤3形成的重组RU具有类似于数据的结构。
在步骤1之后对VRU 311’-314’中的一部分连续子载波进行首尾颠倒的实施例中，可以将每个重组RU的与VRU 311’-314’的一部分对应的部分进行首尾颠倒。
在步骤4，将与VRU 311-314中经首尾颠倒的部分VRU相对应的重组RU进行首尾颠倒，得到物理资源单元PRU 321-324。例如，如果在步骤1中对242-tone VRU 311和313的子载波进行首尾颠倒，则在步骤4中对重组RU 321和323的子载波进行首尾颠倒。如果在步骤1中对242-tone VRU 312和314的子载波进行首尾颠倒，则在步骤4中对重组RU 322和324 的子载波进行首尾颠倒。从而，可以恢复步骤1中的处理对原始RU划分的影响。
基于步骤1至步骤4得到的PRU 321-324分别均匀分布在第一带宽80M上，并且占据不同的子载波位置。此外，PRU 321-324分别具有与VRU 321-324相同的子载波划分，并且PRU 321-324与VRU 321-324存在映射关系。
尽管第一实现方式以第一带宽为80M为例进行描述，但是该机制同样适用于其他带宽(例如，160M、320M等)和其他尺寸的VRU。例如，当第一带宽为160M时，其包含8个242-tone VRU。相应地，在步骤2中可以将每个VRU均匀间隔分成8个RU片段，然后在步骤3中以类似于数独的方式形成8个重组242-tone RU。作为另一示例，当第一带宽为320M时，其包含16个242-tone VRU。相应地，在步骤2中可以将每个VRU均匀间隔分成16个RU片段，然后在步骤3中以类似于数独的方式形成16个重组242-tone RU。此外，还可以将320M带宽分为两个160M带宽分别进行类似操作，在此不再赘述。
在一些示例实施例中，资源单元RU的大小可以不同于242-tone RU，例如可以是106-tone RU、484-tone RU或996-tone RU。例如，在将一组106-tone VRU离散并重组时，可以仍以242-tone为单位进行操作，用户仅使用106-tone RU对应的子载波的离散结果。
在一些示例实施例中，在进行框3的操作时，可以得到符合数独结构的多种重组方案。可以选择使得用户对应的LTF字段具有最小峰均功率比PAPR(peak to average power ratio)的重组方案。此外，这样的重组方案可以被预先配置在通信的发送和接收端，并基于重组方案来在第一带宽上发送或接收PPDU。
在一些示例实施例中，PPDU可以包括指示信息，或者发送端设备可以发送独立于PPDU的指示信息，以指示该PPDU使用的PRU由连续子载波组成还是由离散子载波组成。
本公开的第二实施方式
本公开的第二实施方式涉及与第一实施方式类似的过程。下面将参考图4来描述生成包括离散子载波的PRU的过程400。
如图4所示，针对包含N个242-tone VRU的第一带宽，在框401中，将N个VRU中的第一组VRU的子载波在频域上首尾颠倒，得到经变换的VRU。作为示例，第一组VRU可以包括N个242-tone VRU中RU索引为奇数的VRU。替代地，作为另一示例，第一组VRU也可以包括N个242-tone VRU中RU索引为偶数的VRU。经逆序排列之后，每个VRU的导频子载波在其各自的RU中具有相同的相对位置。
可选地，在框401之后，可以进一步将每个VRU中的至少一部分连续子载波在频域上进行首尾颠倒。例如，可以将每个242-tone VRU中的第二个52-tone RU和第四个52-tone RU进行首尾颠倒。替代地，也可以将第一个52-tone RU和第三个52-tone RU进行首尾颠倒。从而，使每个242-tone VRU中的导频子载波的分布更加均匀。
在框402中，将经变换的N个VRU中的子载波进行索引并各自分为如下N个RU片段：第一RU片段为{1，N+1，2*N+1，…}，第二RU片段为{2，N+2，2*N+2，…}，第三RU片段为{3，N+3，2*N+3，…}……，第N RU片段为{N，2*N，3*N，…}，其中N为第一带宽对应的VRU的数目。
在框403中，将来自不同VRU的N个RU片段组成重组RU，总共得到N个重组RU。换言之，每个重组RU包括分别来自不同的VRU的第一RU片段、第二RU片段…第N RU片段。并且，在频域上，每N个连续子载波对应于不同的VRU。即，在框403中得到的重组 RU具有类似于数据的结构。
如果在框401之后对每个VRU中的至少一部分连续子载波进行首尾颠倒，则在框403之后，可以将每个重组RU中与每个经变换的VRU的至少一部分对应的部分进行首尾颠倒，以恢复对RU划分的影响。
在框404，将与经变换的N个VRU中经首尾颠倒的VRU相对应的重组RU进行首尾颠倒，得到包括离散子载波的N个PRU。例如，如果在框401中对RU索引为奇数的VRU的子载波进行首尾颠倒，则在框404中对RU索引为奇数的重组RU的子载波进行首尾颠倒。如果在框401中对RU索引为偶数的VRU的子载波进行首尾颠倒，则在框404中对RU索引为偶数的重组RU的子载波进行首尾颠倒。从而，可以恢复框401中的变换对原始RU划分的影响。
根据本公开的实施例提供的通信机制，将VRU的连续子载波均匀分布在更大的带宽上，形成由占据整个带宽的离散子载波组成的PRU，能够使发射端设备以更大的发射功率来传输数据。通过将离散后的子载波逐段均匀分布在带宽上，可以保证数据传输不会因为对VRU的离散而引起较大的PAPR增加。基于这样的机制，本公开的技术方案能够充分利用带宽资源，提高了系统效率。
本公开的第三实施方式
在本公开的第三实施方式中，提供了在第一带宽上以996-tone RU为单位离散子载波的示例过程。假设第一带宽可以为160M、320M，其中包括N个996-tone RU，每个996-tone RU可以包括四个242-tone RU，例如第一242-tone RU、第二242-tone RU、第三242-tone RU以及第四242-tone RU。
在确定用于传输PPDU的PRU时，可以将每个996-tone VRU中的第一组242-tone VRU进行首位颠倒。例如，可以将每个996-tone VRU的第二242-tone RU和第四242-tone RU，也即偶数索引的242-tone RU进行首尾颠倒。替代第，也可以将每个996-tone VRU的第一242-tone RU和第三242-tone RU，也即奇数索引的242-tone RU进行首尾颠倒，本公开在这方面不进行限制。这样，经变换的每个996-tone VRU内的导频子载波的位置分布更均匀。应当理解的是，上述步骤是可选步骤。在实践中，不进行上述步骤也是可行的。
将每个996-tone RU的子载波索引为{1,…,996}，并将经索引的子载波分为如下N个RU片段：第一RU片段为{1，N+1，2*N+1，…}，第二RU片段为{2，N+2，2*N+2，…}，第三RU片段为{3，N+3，2*N+3，…}……，第N RU片段为{N，2*N，3*N，…}，其中N等于第一带宽对应的VRU的数目。
接下来，利用来自不同的N个996-tone VRU的N个RU片段重组为N个996-tone PRU。重组后的996-tone PRU具有类似于数独的结果，即每个996-tone PRU都包括N个RU片段第一RU片段、第二RU片段、…第N RU片段，且同一重组的996-tone PRU内的N个RU片段均来自N个不同的996-tone VRU。从频率上看，在第一带宽上每N个相邻子载波均来自不同的N个996-tone PRU。
在一些实施例中，如果在确定PRU时首先对子载波执行了首位颠倒的可选步骤，则分别将每个重组的996-tone PRU中的相应242-tone PRU进行首尾颠倒。从而，消除上述可选步骤对子载波划分的影响。
根据本公开的实施例提供的通信机制，将VRU的连续子载波均匀分布在更大的带宽上， 形成由占据整个带宽的离散子载波组成的PRU，同时不改变原始的子载波资源划分结果。这样，可以允许发射端设备以更大的发射功率来传输数据。通过将离散后的子载波逐段均匀分布在带宽上，可以保证数据传输不会因为对VRU的离散而引起较大的PAPR增加。因此，本公开的技术方案能够充分利用带宽资源，提高了系统效率。
应当理解的是，基于本公开的第一至第三实施方式可以得到符合数独结构的多种子载波离散方案。在实践中，可以根据需要选择特定的子载波离散方案预先配置在发射端和接收端，并基于该方案进行通信。
下面的表4至表6提供了根据本公开提出的通信机制基于不同子载波规划的RU索引、子载波范围和导频子载波索引。这些重组方案可以产生较低的PAPR和较好的系统性能。当然，其他的重组方案也是可行的。

应当理解的是，表4至表7中示出的具体子载波规划以及本公开的示例实施例的原理同样适用于总带宽或RU的大小为其他数值的带宽配置。例如，当在总带宽320MHz上发送或接收PPDU时，可以将总带宽分为各自为160MHz的第一部分带宽和第二部分带宽，在每部分带宽上可以应用基于表6或表7的子载波规划。作为另一示例，对于总带宽320MHz，可以将其分为各自为80MHz的第一部分带宽、第二部分带宽、第三部分带宽和第四部分带宽，并且在每部分带宽上可以应用基于表4或表5的子载波规划，以此类推。因而，在此不针对基于类似原理的带宽配置与子载波规划进行赘述。
图5示出了根据本公开的实施例的通信方法的流程图。方法500可以在图2所示的接入点AP 210处或STA端实现，为了方便讨论，以下将结合图2来描述方法500。应当理解，方法500同样适用于其他通信场景和设备。
以下以AP 210为例来描述方法500，应当理解，STA端也可以执行方法500，例如STA 220-1或STA 220-2都可以执行方法500。
