Description

资源单元合并指示的方法和通信装置
本申请要求于2020年01月10日提交中国专利局、申请号为202010028036.6、申请名称为“资源单元合并指示的方法和通信装置”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
本申请涉及通信领域，更为具体的，涉及一种资源单元合并指示的方法和通信装置。
背景技术
随着无线局域网(wireless local area network，WLAN)系统的802.11各个标准版本的演进，802.11标准在资源的分配上需要进一步的提高。在用户频带资源分配上，一个用户的频带资源的分配是以资源单元(Resource Unit，RU)为单位。例如，在802.11ax的一个20MHz信道内，可以包含多个RU，形式可以是26-tone RU、52-tone RU、106-tone RU。其中，tone表示子载波。
但是，802.11ax目前仅支持将单一RU分配给一个或者多个用户，并不支持将多个连续或者不连续的RU分配给某一个或多个用户使用。这会降低系统RU的分配灵活性，也使系统在有前导码打孔的情况下频谱利用率不高。

具体实施方式
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)系统，例如，本申请实施例可以适用于WLAN当前采用的国际电工电子工程学会(institute of electrical and electronics engineers，IEEE)802.11系列协议中的802.11ac/802.11ax/802.11be或者未来IEEE 802.11系列中任意一种协议。
图1示出了一例适用于本申请实施例的通信系统的示意图，如图1所示的通信系统可以是WLAN系统，也可以是广域网系统。图1的通信系统可以包括一个或多个AP，以及一个或多个STA，图1以两个AP(AP 1和AP 2)和两个用户站点(station，STA)(STA 1和STA 2)为例，其中，AP与AP、AP与STA、STA与STA之间可以通过各种标准进行无线通信。本申请提供的方案可以应用在AP与AP之间的通信、STA与STA之间的通信以及AP与STA之间的通信。
用户站点(STA)也可以称为终端、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)。站点可以为无线通信芯片、无线传感器或无线通信终端。例如站点为支持无线保真(wireless fidelity，WiFi)通信功能的移动电话、支持WiFi通信功能的平板电脑、支持WiFi通信功能的机顶盒、支持WiFi通信功能的智能电视、支持WiFi通信功能的智能可穿戴设备、支持WiFi通信功能的车载通信设备和支持WiFi通信功能的计算机、支持WiFi通信功能的智能家居设备，比如智能摄像头，智能水表电表、传感器，以及支持WiFi通信功能的车联网设备，或物联网设备，传感器等。可选地，站点可以支持当前网络系统或者未来网络系统下802.11制式的设备。
本申请所涉及到的接入点AP是一种部署在无线通信网络中为站点提供无线通信功能的装置，可用作WLAN的中枢，所述接入点AP还可以为基站、路由器、网关、中继器，通信服务器，交换机或网桥等，其中，所述基站可以包括各种形式的宏基站，微基站，中继站等。在此为描述方便，将上述为站点STA提供无线通信功能服务的装置统称为接入点或AP。
本申请实施例中AP与STA可以通过无线局域网进行通信，并将STA的数据传输至网络侧，或将来自网络侧的数据传输至STA。AP也称之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，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芯片的终端设备或者网络设备。可选地，AP可以为支持当前网络系统或者未来网络系统下802.11制式的设备。
具体地，AP和STA之间可以多用户多入多出(multi-users multiple-input multiple-output，MU-MIMO)技术进行无线通信。在本申请实施例中，每个STA配备一个或多个天线。每个AP支持多站点协同和/或联合传输。
还应理解。图1只是示意图，该通信系统中还可以包括其它网络设备或者终端设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。本申请的实施例对该通信系统中包括AP和STA的数量不做限定。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软 盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
在带宽配置方面，802.11ax目前支持的带宽配置包括：20MHz、40MHz、80MHz、160MHz及80+80MHz。其中，160MHz与80+80MHz的区别在于前者为连续频带，而后者的两个80MHz间可以分离。在802.11be中，将对320MHz等配置进行支持。
在用户频带资源分配上，一个用户的频带资源的分配并不是以信道为单位，而是以资源单元(Resource Unit，RU)为单位。在802.11ax的一个20MHz信道内，可以包含多个RU，形式可以是26-tone RU、52-tone RU、106-tone RU。其中，tone表示子载波，例如，26-tone RU表示由26个子载波组成的RU，该26-tone RU可以被分配给一个用户使用。此外，RU也可以是242-tone、484-tone、996-tone等形式分配给一个或者多个用户使用。
但是，802.11ax目前仅支持将单一RU分配给一个或者多个用户，例如，对于尺寸(size)大于或者等于106个子载波组成的资源的单元(106-tone RU)支持的MU MIMO的用户数可以大于或者等于8。但是802.11ax并不支持将多个连续或者不连续的RU分配给某一个或多个用户使用。这会降低系统RU的分配灵活性，也使系统在有前导码打孔的情况下频谱利用率不高。
有鉴于此，本申请提供了一种资源单元合并指示的方法，可以支持一个或多个用户使用多个连续或者不连续的RU进行数据传输，并将多个RU的合并情况指示给该用户，提高了系统RU的分配灵活性，提高了系统频谱利用率。
为了更清楚的说明本申请提供的方法，首先简单说明RU的分配和指示方式。
目前，主要利用信令字段(Signal Field，SIG)向用户通知RU的分配。SIG在每个20MHz上是单独编码的例如，例如，该信令字段可以是高效信令字段B(High Efficient Signal Field-B，HE-SIG-B)，或者也可以为超高吞吐率信令字段(Extremely High Throughput Signal Field，EHT-SIG)，或者还可是未来网络系统下802.11中的信令字段等。在每一个20MHz上的SIG的信息结构如图2所示。
如图2中所示的，HE-SIG分为两部分，其中第一部分是公共字段(公共部分字段)，包括1～N个资源单元(resource unit，RU)分配子字段(RU allocation subfield)，以及当带宽大于等于80MHz时存在的中间26-子载波(Center 26-Tone)资源单元指示子字段(Center 26-Tone RU indication)，然后是用于校验的循环冗余码(cyclic redundancy code,CRC)以及用于循环解码的尾部(Tail)子字段。一个资源单元分配子字段对应一个20MHz的频域资源单元的分配，一个资源单元子字段指示了20MHz内包括的一个或者多个资源单元的大小和位置。在逐个站点字段(也可以叫做用户特定字段(user specific field)，按照资源单元分配的顺序，存在着1～M个站点字段(User Field)，M个站点字段通常是两个为一组，每两个站点字段后有一个CRC和tail字段，除了最后一组，可能会存在1个或者2个站点字段。在本申请中，站点字段也可以称为用户字段。
其中，一个资源单元分配子字段为一个资源单元分配索引，一个资源单元分配索引指示了20MHz内包括的一个或者多个资源单元的大小和位置。其中，至少一个站点字段的 顺序和资源单的分配顺序是对应的。每一个站点字段指示在资源单元的分配中包括的RU内被分配的STA的站点信息。当一个资源单元分配子字段指示的资源单元的排列组合中包括由大于或者等于106个子载波组成的资源单元时，该资源单元分配索引还用于指示由大于或者等于106个子载波组成的资源单元支持的MU MIMO用户数。其中MU MIMO用户数大于或者等于8。
当数据分组带宽为20MHz时，如图3所示的，图3所示为数据分组带宽为20MHz时的资源单元可能的分配方式的示意图。整个20MHz带宽可以由一整个242个子载波组成的资源单元(242-tone RU)组成，也可以由26个子载波组成的资源单元(26-tone RU)、52个子载波组成的资源单元(52-tone RU)、106个子载波组成的资源单元(106-tone RU)的各种组合组成。其中“Tone”可以理解为子载波。除了用于传输数据的RU，此外，还包括一些保护(Guard)子载波，空子载波，或者直流(direct current，DC)子载波。
当数据分组带宽为40MHz时，如图4所示的，图4所示为数据分组带宽为40MHz时资源单元的各种分配方式。整个带宽大致相当于20MHz的子载波分布的复制。整个40MHz带宽可以由一整个484个子载波组成的资源单元(484-tone RU)组成，也可以由26-tone RU，52-tone RU，106-tone RU，242-tone RU的各种组合组成。
当数据分组带宽为80MHz时，如图5所示的，图5所示为数据分组带宽为80MHz时的资源单元可能的分配方式的示意图。整个带宽大致相当于20MHz的子载波分布的复制。整个80MHz带宽可以由一整个996个子载波组成的资源单元(996-tone RU)组成，也可以由484-tone RU、242-tone RU，106-tone RU，52-tone RU，26-tone RU的各种组合组成。并且，在整个80MHz带宽的中间，还存在一个由两个13-tone子单元组成的中间26-tone RU(Center 26-Tone RU)。
类似的，当数据分组带宽为160MHz时，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(由1992个子载波组成的资源单元)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。并且，在整个80MHz带宽的中间，还存在一个由两个13-tone子单元组成的中间26-tone RU。
以上的各种子载波分布方式中，以242-tone RU为单位，左边的242-tone RU可以看作为数据分组带宽最低频率，右边的242-tone RU可以看作最高频率。例如，以图6所示的为例，从左到右，可以对242-tone RU依次进行标号：1，2，3，4。又例如，当数据分组带宽为160MHz时，从左到右，可以对242-tone RU依次进行标号：1，2，…8。应该理解的是，在数据字段，8个242-tone RU与8个20MHz信道按照频率从低到高一一对应，但是由于中间26-tone RU的存在，在频率上并不完全重合。
802.11ax引入了内容信道(content channel，CC)的概念。内容信道可以理解为SIG-B包括的内容，例如，内容信道可以包括至少一个资源单元分配子字段(RU allocation subfield)、多个逐个站点字段、用于校验的CRC以及用于循环解码的尾部(Tail)子字段。图6所示的为当数据分组带宽为20MHz时内容信道的结构的示意图。如图6所示的，当数据分组带宽只有20MHz时，SIG-B只包含1个内容信道，该内容信道中包含1个资源单元分配子字段，用于指示数据部分第一个242-tone RU范围内的资源单元分配指示。1个资源单元分配子字段为一个资源单元分配索引，用于指示一个242-tone RU内所有可能 的资源单元的分配方式。此外，对于尺寸大于或者等于106-tone的RU(即由大于或者等于106个子载波组成的RU)，同时通过该索引，指示该RU中进行SU/MU-MIMO传输的用户数。
举例说明，假设资源单元分配子字段为8个比特的索引，可以通过8个比特索引的方式指示出一个242-tone RU内所有可能的资源单元的分配方式。此外，对于尺寸大于或者等于106-tone的RU(即由大于或者等于106个子载波组成的RU)，同时通过8个比特的索引，指示该RU中进行SU/MU-MIMO传输的用户数。8比特的索引资源单元索引表如表1所示。

表1中，第一列代表8比特索引，中间列#1～#9代表着不同资源单元。表格的数字代表该资源单元所包含的子载波数目。例如，索引00111y 2y 1y 0表示整个242-tone RU被分成了52-tone RU、52-tone RU、26-tone RU、106-tone RU这4个RU组成。第三列的条目数量指示相同资源单元分配的条目个数，即相同资源单元排列方式对应的不同的索引个数。对于索引00111y 2y 1y 0而言，之所以会存在8个条目，是因为在指示242-tone RU资源单元分配方式的同时，y 2y 1y 0还用于指示在该106-tone RU内所包含的SU/MU-MIMO传输的用户数，对应1～8个用户。即利用3比特的y 2y 1y 0指示该106-tone RU内支持的1至8个用户。8个条目可以看成表格中独立的8行，这8行对应相同的资源单元分配方式，每一行对应不同的106-tone RU内支持的用户数。在802.11ax标准中，规定子载波数大于或者等于106的RU可以进行MU-MIMO，所以当表2中的某一行中存在子载波数大于等于106的RU时，条目数会大于1。对应的，逐个站点字段中按照资源分配的顺序，指示在该242-tone RU范围内被分配的STA的站点信息。
表1所示的大部分的RU配置是在242-tone的范围内，另外有少部分属于指示该RU属于242-tone RU、484-tone RU、996-tone RU。其中，每8比特的资源单元分配子字段将告知对应20MHz范围内的RU分配状况。可以理解的是：20MHz带宽对应1个资源单元分配子字段，40MHz带宽对应2个资源单元分配子字段，80MHz带宽对应4个资源单元分配子字段、160MHz带宽对应8个资源单元分配子字段，320MHz带宽对应16个资源单元分配子字段。
图7所示的为当数据分组带宽为40MHz时内容信道的结构的示意图。如图7所示，当数据分组带宽为40MHz时，存在两个SIG-B内容信道，CC1和CC2。其中在第1个SIG-B信道的CC1包括第1个242-tone RU范围内的资源单元分配子字段以及所对应的逐个站点字段。第2个HE-SIG-B信道的CC2包括第2个242-tone RU范围内的资源单元分配子字段以及所对应的逐个站点字段。
图8所示的为当数据分组带宽为80MHz时内容信道的结构的示意图。如图8所示，当数据分组带宽为80MHz时，仍然存在2个CC，一共4个信道。因此整体上按照频率由低到高，按照CC1、CC2、CC1、CC2的结构在4个信道上对资源单元分配信息进行指示，其中在CC1中包括第1个和第3个242-tone RU范围内的资源单元分配子字段以及其范围内所对应的逐个站点字段。CC2包括第2个和第4个242-tone RU范围内的资源单元子字段以及其范围内所对应的逐个站点字段。另外在两个CC上，都会包括80MHz的中间26-tone RU指示字段，指示该资源单元是否被用于传输数据。
类似的，当数据分组带宽为160MHz时，仍然存在2个CC，一共8个信道,相当于在80MHz的基础上进一步扩展。
本申请实施例中，可以支持将不同的RU进行合并，并且可以将RU的合并信息通过信令字段通知给用户设备，例如，信令字段可以为信令字段B，也可以为极高吞吐量信令字段(EHT SIG)，或者为EHT SIG中包括的信令字段，或者，也可以为EHT SIG-B，或者还可以是物理层协议数据单元(physical layer protocol data unit，PPDU)包括的其他字段。本申请在此不作限制。
下面说明本申请实施例中的提供的一些RU可能的合并情况，为了便于说明，将RU分为小RU(small-size RU)与大RU(large-size RU)两种类型，其中小RU的集合为{26,52,106}，大RU的集合为{242,484,996}，集合中的数字表示组成RU的子载波的个数。
可选的，在本申请实施例中，可以设置下列的RU合并规则：
第一：小RU与大RU之间不合并；
第二：小RU之间不进行跨20MHz的合并；
第三：小RU之间的合并应是连续的，可选的，也可以是不连续的。
在本申请实施例中，将多个连续的或者不连续的RU合并称为多RU(Multi-RU)。组成该Multi-RU的多个连续的或者不连续的RU可以分配给一个或多个用户。可选的，其中的多个连续的或不连续的RU可以由802.11ax定义，且合并的RU的个数不限。例如，本申请实施例中的20MHz内，两个小RU的合并，也可以理解为两个小RU合并为一个Multi-RU。
基于上述的规则：对于20MHz内的小RU合并，可能的小RU的合并的方式包括：(52-tone RU+26-tone RU)、(106-tone RU+26-tone RU)、(52-tone RU+106-tone RU)的方式，换句话说，20MH中包括的Multi-RU可以有三种；
第一种Multi-RU包括：一个52-tone RU和一个26-tone RU合并组成。
第二种Multi-RU包括：一个106-tone RU和一个26-tone RU合并组成。
第三种Multi-RU包括：一个52-tone RU和一个106-tone RU合并组成。
并且，在本申请实施例中，20MHz内，在一个RU allocation subfield指示的频域资源单元的分配中，可能出现上述的三种Multi-RU中的任意一种Multi-RU，或者，可能出现上述的三种Multi-RU中的第一种Multi-RU和第二种Multi-RU，并且，对于出现的第一种Multi-RU的次数(或者个数)不作限制，例如，可以出现一个或者多个第一种Multi-RU。例如，假设对于某一个RU allocation subfield指示的频域资源单元的分配方式中包括两个52-tone RU和至少两个26-tone RU的情况，则该频域资源单元的分配方式中可以包括两个第一种Multi-RU。一个52-tone RU与一个26-tone RU合并组成一个第一种Multi-RU，另 一个52-tone RU与另一个26-tone RU合并组成另一个第一种Multi-RU。
例如，表2所示的为一例20MHz内的小RU可能出现的合并方式
表2
Figure PCTCN2021070851-appb-000003
表2中，A表示该20MHz内存在一个第一种Multi-RU,即存在一个52-tone RU和一个26-tone RU的合并，B表示该20MHz内存在两个第一种Multi-RU，即存在一个52-tone RU和一个26-tone RU的合并，以及另一个52-tone RU和另一个26-tone RU的合并。C表示该20MHz内存在三个第一种Multi-RU，即存在一个52-tone RU和一个26-tone RU的合并，另一个52-tone RU和另一个26-tone RU的合并，以及又一个52-tone RU和又一个26-tone RU的合并。D表示该20MHz内存在一个第三种Multi-RU，即存在一个106-tone RU和一 个56-tone RU的合并。E表示该20MHz内存在一个第二种Multi-RU，即存在一个106-tone RU和一个26-tone RU的合并。
表格中的“或”表示在同一个资源单元的分配方式中，对应的A至E中的只能出现一种。例如，对于资源单元的分配方式为：52-tone RU、26-tone RU、26-tone RU、26-tone RU、26-tone RU、26-tone RU、52-tone RU的情况，第一个52-tone RU后的(A,或者)与第二个52-tone RU(B,或)表示：在这种资源单元分配方式下，可能出现的Multi-RU为：两个52-tone RU中的任意一个52-tone RU与任意一个26-tone RU合并成一个第一种Multi-RU，即存在一个第一种Multi-RU，为合并方式A。或者，第一个52-tone RU与任意一个26-tone RU合并成一个第一种Multi-RU，第二个52-tone RU与另外的任意一个26-tone RU合并成另一个第一种Multi-RU，即存在两个第一种Multi-RU，为合并方式B。
又例如，对于资源单元的分配方式为：52-tone RU、52-tone RU、26-tone RU、106-tone RU的情况，第一个52-tone RU后的(A,或者)与106-tone RU(E或D,或)表示：在这种资源单元分配方式下，可能出现的Multi-RU为：两个52-tone RU中的任意一个52-tone RU与一个26-tone RU合并成一个第一种Multi-RU，即存在一个第一种Multi-RU，为合并方式A。或者，两个52-tone RU中的任意一个52-tone RU与一个106-tone RU合并成一个第三种Multi-RU，即存在一个第三种Multi-RU，为合并方式D。或者，一个106-tone RU与一个26-tone RU合并成一个第二种Multi-RU，即存在一个第二种Multi-RU，为合并方式E。
应理解，在本申请实施例中，对于上述的第一种Multi-RU。第二种Multi-RU以及第三种Multi-RU，均不限定上述的各个合并方式中52-tone RU、106-tone RU、以及26-tone RU的位置。也就是说，上述的合并方式A仅仅表示在对应的RU分配存在一个第一种Multi-RU(52-tone RU+26-tone RU)，对于一个26-tone RU以及一个52-tone RU的位置不作限制。上述的合并方式B仅仅表示在对应的RU分配存在两个第一种Multi-RU(52-tone RU+26-tone RU)、(52-tone RU+26-tone RU))，对于合并的26-tone RU以及52-tone RU的位置也不作限制。类似的，上述的合并方式D仅仅表示在对应的RU分配存在一个第三种Multi-RU(106-tone RU+52-tone RU)，对于合并的一个106-tone RU与一个52-tone RU的位置也不作限制。上述的合并方式E仅仅表示在对应的RU分配存在一个第二种Multi-RU(106-tone RU+26-tone RU)，对于合并的一个106-tone RU与一个26-tone RU的位置也不作限制。换句话说，表2所示的小RU的合并方式为非受限的合并方式，对进行合并的106-tone RU、26-tone RU以及52-tone RU的位置不作限制。
可选的，在本申请一些可能的实现方式中，所有可以合并的52-tone RU或106-tone RU与26-tone RU合并时可以遵循以下原则：与20MHz内可以与离自己最近的26-tone RU合并。例如，可以是在同距离情况下优先合并右边的26-tone RU；也可以是在同距离情况下优先合并左边的26-tone RU；也可以是同距离下在左边106-tone RU或者52-tone RU范围内优先合并左边或者右边的26-tone RU，同距离下在右边106-tone RU或者52-tone RU范围内优先合并右边或者左边的26-tone RU等。例如，对于第一种Multi-RU(52-tone RU+26-tone RU)，可以是与一个52-tone RU连续的左边或者右边的26-tone RU与该52-tone RU合并组成一个第一种Multi-RU。对于第二种Multi-RU(106-tone RU+26-tone RU)，可以是与一个106-tone RU连续的左边或者右边的26-tone RU与该106-tone RU合并组成 一个第二种Multi-RU。对于第三种Multi-RU(106-tone RU+52-tone RU)，可以是与一个106-tone RU连续的(或者距离最近的)左边或者右边的52-tone RU与该106-tone RU合并组成一个第三种Multi-RU。换句话说，上述的小RU的合并方式为受限的合并方式，即对进行合并的106-tone RU、26-tone RU以及52-tone RU的位置具有一定的限制。
例如，表3所示的为本申请实施例提供的另一种20MHz内的小RU合并可能出现的合并方式。
表3
Figure PCTCN2021070851-appb-000004
表3中，对于任意一行子载波的分布中，标号为(a)的RU可以合并，得到一个Multi-RU，标号为(b)的RU可以合并，得到一个Multi-RU。并且，在相同的RU分配中，可以同时存在(a)方式的RU合并和(b)方式的RU合并。
又例如，表4所示的为本申请实施例提供的另一种20MHz内的52-tone RU与106-tone RU合并可能出现的合并方式。
表4
Figure PCTCN2021070851-appb-000005
表4中，对于任意一行子载波的分布中，标号为(c)的RU可以合并得到一个Multi-RU。
应理解，在本申请实施例中，对于20MHz内的小RU的合并，还可以存在其它可能的合并方式，表2至表4仅仅示例性的列出一些可能的RU合并方式，而不应该对本申请实施例中的20MHz内的小RU的合并方式产生任何限制。
还应理解，表3和表4所示的为受限的小RU合并方式。
对于大RU的合并方式，下面将分别以80MHz带宽、160MHz带宽、320MHz带宽为例进行说明。本申请实施例中的跨242-tone的大RU合并，也可以理解为多个大RU合并为一个Multi-RU。对于信道中存在前导码打孔的情况下，采用大RU的合并方式可以将未被打孔的多个RU合并分配给一个或多个用户，提升前导码打孔情况下的RU分配灵活度和频谱利用率。
表5所示的80MHz带宽可能存在的RU合并方式，由于80MHz带宽对应4个资源单元分配子字段，1个资源单元分配子字段用于指示一个242-tone RU。4个资源单元分配子字段按照顺序在2个CC上依次排列。表5中的位置表示4个资源单元分配子字段指示的4个242-tone RU的先后位置。如表5所示的，不同的组合方式分别表示对应的两个大RU合并为一个Multi-RU。也就是说，对于80MHz带宽中包括的Multi-RU一共有五种不同的Multi-RU。表5中不同的组合方式分别表示不同的Multi-RU。可以看出，对于80MHz带宽中包括的Multi-RU可以有二种：分别为：(242-tone RU+242-tone RU)、(484-tone RU+242-tone RU)。
表5
Figure PCTCN2021070851-appb-000006
对于160MHz带宽，由于160MHz带宽对应8个资源单元分配子字段，1个资源单元分配子字段用于指示一个242-tone RU，因此，对于160MHz带宽，由两个或者更多个大RU组成的Multi-RU可以有以下几种：分别为：(996-tone RU+996-tone RU)、(242-tone RU+484-tone RU)、(242-tone RU+484-tone RU+484-tone RU)、(242-tone RU+484-tone RU+242-tone RU)、(484-tone RU+996-tone RU)、(996-tone RU+484-tone RU)。其中，每个括号表示一种Multi-RU。
例如，表6所示的为本申请实施例提供的一种160MHz带宽可能存在的RU合并方式，由于160MHz带宽对应8个资源单元分配子字段，1个资源单元分配子字段用于指示一个242-tone RU。表6所所示的160MHz带宽可以由两个996-tone RU组成。表6中的位置表示2个996-tone RU的先后位置。如表6所示的，不同的组合方式分别表示对应的多个大RU合并为一个Multi-RU。
表6
Figure PCTCN2021070851-appb-000007
应该理解，表6仅仅是示例性的，不应该对于160MHz带宽的RU合并方式产生任何限制。
对于320MHz中的合并组合，可以是基于上述160MHz的合并，也可以是基于上述的80MHz的合并等。例如，表7所示的为本申请实施例提供的一种320MHz带宽可能存在的RU合并方式，如表7所示的，不同的组合方式分别表示对应的两大RU合并为一个Multi-RU。
表7

应理解，上述的表5至表7仅仅本申请实施例中的跨242-tone的大RU合并方式的一些例子，不应该对本申请实施例中的跨242-tone的大RU合并方式产生任何限制。并且，表5至表7所示的仅仅是受限的大RU合并方式，对于需要合并的大RU的个数、位置以及组合等均有一定的限制。也就是说，预先定义了可以进行合并的大RU的组合以及位置等。
下面结合图9详细说明本申请提供的资源单元合并指示的方法，图9是本申请一个实施例的资源单元合并指示的方法200的示意性流程图，该方法200可以应用在图1所示的场景中。当然也可以应用在其他通信场景或者通信系统中，本申请实施例在此不作限制。
应理解，下文的描述中，以发送设备和接收设备作为各个实施例的执行方法的执行主体为例，对各个实施例的方法进行说明。发送设备可以是上述的AP或者STA，接收设备也可以是上述的AP或者STA。作为示例而非限定，执行方法的执行主体也可以是应用于发送设备和接收设备的芯片。
如图9所示，图9中示出的方法200可以包括步骤S210至步骤S220。下面结合图9详细说明方法200中的各个步骤。该方法200包括：
S210，发送设备确定PPDU，该PPDU包括信令字段，该信令字段包括至少一个资源单元分配子字段和与至少一个资源单元分配子字段对应的合并指示，一个资源单元分配子字段对应一个20MHz的频域资源单元的分配，一个资源单元子字段指示了20MHz内包括的多个资源单元的大小和位置，该信令字段包括还包括合并指示，该合并指示用于指示该至少一个资源单元分配子字段指示的资源单元的合并信息。即该信令字段包括资源单元分配子字段和与资源单元分配子字段对应的合并指示，该资源单元分配子字段指示多个资源单元，该合并指示用于指示该多个资源单元的合并信息。
其中，一个资源单元分配子字段指示可以指示一个20MHz的频域上包括的多个资源单元，该多个资源单元均为小RU(small-size RU)，在这种情况下，与一个资源单元分配子字段对应的合并指示用于指示一个20MHz的频域上的这些小RU的合并情况。
S220，发送设备发送该PPDU。相应的，接收设备接收该PPDU。
具体而言，在S210中，发送设备向接收设备需要发送数据时，会向接收设备发送PPDU，PPDU包括信令字段(Signal Field，SIG)。可选的，该信令字段可以为上述的 EHT-SIG-B。该PPDU除了包括信令字段，还可以包括EHT-SIG-A字段、数据字段等。信令字段包括至少一个资源单元分配子字段(RU allocation subfield)。该信令字段还可以包括至少一个站点字段(User Field)。一个资源单元分配子字段对应一个20MHz的频域资源单元的分配，一个资源单元子字段指示了20MHz内包括的多个资源单元的大小和位置其中，至少一个站点字段的顺序和资源单的分配顺序是对应的。每一个站点字段指示在资源单元的分配中包括的RU内被分配的STA的站点信息。并且，所述信令字段包括还包括合并指示(或者也可以称为合并指示比特)，所述合并指示用于指示所述至少一个资源单元分配子字段指示的资源单元的合并信息。在S220，接收设备接收到该PPDU后，根据该信令字段以及指示比特，便可以确定RU的合并信息，从而确定与自己对应的多个RU，提高了系统RU的分配灵活性，提高了系统的频谱利用率。
如图10所示，图10中示出的为本申请提供另一例资源单元合并指示的方法300的示意性交互图。方法300可以包括步骤S310至步骤S320。下面结合图10详细说明方法300中的各个步骤。该方法300包括：
S310，发送设备生成PPDU，该PPDU包括信令字段，该信令字段包括多个资源单元分配子字段和与多个资源单元分配子字段对应的合并指示，一个资源单元分配子字段对应一个20MHz的频域资源单元的分配，一个资源单元子字段指示了20MHz内包括的一个资源单元的大小和位置，这一个资源单元为大RU(large-size RU)，一个资源单元为242-tone RU，484-tone RU或996-tone RU。该多个资源单元分配子字段指示多个资源单元。该信令字段包括还包括合并指示，该多个合并指示用于指示该多个资源单元的合并信息，一个合并指示与一个资源单元分配子字段所指示的RU对应。也就是说，多个合并指示用于指示多个大RU的合并信息。即该信令字段包括多个资源单元分配子字段和多个合并指示，该多个资源单元分配子字段指示多个资源单元，该多个合并指示用于指示该多个资源单元的合并信息，一个合并指示与一个资源单元分配子字段所指示的RU对应，一个资源单元为242-tone RU，484-tone RU或996-tone RU。
S320，发送设备发送该PPDU。相应的，接收设备接收该PPDU。
具体而言，在S310中，发送设备向接收设备需要发送数据时，会向接收设备发送PPDU，PPDU包括信令字段(Signal Field，SIG)。可选的，该信令字段可以为上述的EHT-SIG-B。该PPDU除了包括信令字段，还可以包括EHT-SIG-A字段、数据字段等。信令字段包括至少一个资源单元分配子字段(RU allocation subfield)。该信令字段还可以包括至少一个站点字段(User Field)。一个资源单元分配子字段对应一个20MHz的频域资源单元的分配，一个资源单元子字段指示了20MHz内包括的一个大RU的大小和位置。该大RU为242-tone RU，484-tone RU或996-tone RU，至少一个站点字段的顺序和资源单元分配顺序是对应的。每一个站点字段指示在资源单元的分配中包括的RU内被分配的STA的站点信息。并且，所述信令字段包括还包括合并指示(或者也可以称为合并指示比特)，所述合并指示用于指示所述多个资源单元分配子字段指示的多个资源单元的合并信息。也就是说，该合并指示用于指示跨242-tone RU的大RU合并。在S320，接收设备接收到该PPDU后，根据该信令字段以及指示比特，便可以确定大RU的合并信息，从而确定与自己对应的多个大RU，提高了系统RU的分配灵活性，提高了系统的频谱利用率。
下面将分别进行说明。
在本申请一些可能的实现方式中，可以对每一个资源单元分配子字段进行扩展，例如，基于现有的资源单元分配子字段，在其后面进行扩展，可以在现有的任意一个或者多个资源单元分配子字段后面添加比特，用于指示该资源单元分配子字段指示的资源单元的合并信息。例如，每个资源单元分配子字段中包括合并指示。该合并指示用于指示该资源单元分配子字段指示的资源单元的合并信息。
例如，如表1所示的，在本申请实施例中，可以在表1中8比特索引的资源单元分配子字段后面进行扩展，将8比特索引的资源单元分配子字段扩展为9比特、10比特或更多的比特，利用扩展的1比特或者多比特来指示资源单元分配子字段指示的资源单元的合并情况，也就是说，扩展的1比特或者多比特为合并指示，可以利用该合并指示指示资源单元分配子字段指示的资源单元的合并，包括242-tone内的小RU合并以及跨242-tone的大RU合并。
对于242-tone内的小RU合并，由上述的分析可知，一个20MHz内最多存在3个Multi-RU，这3个Multi-RU为3个第一种Multi-RU，即存在3个形式为(52-tone RU+26-tone RU)的Multi-RU。因此可以使用2比特进行指示可以实现0至3个Multi-RU的指示。因此，可以将表1中的8比特索引的资源单元分配子字段扩展为10比特，其中，第九比特和第十比特为上述的合并指示。
例如，一种可能的实现方式为：多个资源单元分配子字段中的一个资源单元分配子字段对应一个20MHz的频域资源单元的分配以及资源单元的合并情况，一个资源单元分配子字段指示20MHz内包括的一个或多个资源单元的大小和位置，以及，资源单元的合并情况。资源单元分配子字段包括多个比特(bits)，其中一部分bits用于指示一个20MHz的频域资源单元的分配，即一个或多个资源单元的大小和位置，另外一部分bits用于指示一个20MHz的频域资源单元的合并情况。例如，资源单元分配子字段包括10bits，其中前8bits用于指示资源单元的分配，后2bits指示该资源单元的分配中频域资源单元的合并情况，可选的，前8bits指示的资源单元分配方式，可以参考802.11ax中的HE-SIGB中的设计，例如表1，当然需要说明的是，对于20MHz包括大于等于106-tone RU的情形中，由于大于等于106-tone的RU可以用于MU-MIMO传输，因此这8bits中还可以有一部分bits用于指示在大于等于106-tone的RU中进行MU-MIMO传输的用户的个数。后2bits也可以称为合并指示，该合并指示位取值为00、01、10、11分别可以指示不同的合并情况。例如，两比特位取值00表示该资源单元的分配方式中无多RU合并，即不存在Multi-RU。两比特位取值01表示该资源单元的分配方式中有一个Multi-RU，这一个Multi-RU可以为：第一种Multi-RU(52-tone RU+26-tone RU)、第二种Multi-RU(106-tone RU+26-tone RU)、或者为第三种Multi-RU(52-tone RU+106-tone RU)。两比特位取值10表示该资源单元的分配方式中有两个Multi-RU，这两个Multi-RU可以为两个第一种Multi-RU，或者，一个为第一种Multi-RU，另一个为第二种Multi-RU(106-tone RU+26-tone RU)。两比特位取值11表示该资源单元的分配方式中有3个Multi-RU，这3个Multi-RU均为第一种Multi-RU(52-tone RU+26-tone RU)。
可选的，在本申请实施例中，对于合并指示指示的Multi-RU，组成该Multi-RU的小RU的位置可以是预定义的。例如，两比特位取值01时，如果指示第一种Multi-RU，则默认指示在一个资源单元的分配方式中，从左向右第一个52-tone RU与该52-tone RU左 侧的第一个或者右侧第一个(或者与该52-tone RU连续的一个)26-tone RU合并得到一个第一种Multi-RU。类似的，如果指示第二种Multi-RU，则默认指示在一个资源单元的分配方式，从左向右第一个106-tone RU与该106-tone RU左侧的第一个或者右侧第一个(或者与该106-tone RU连续的一个)26-tone RU合并得到一个第二种Multi-RU。如果指示第三种Multi-RU，则默认指示在一个资源单元的分配方式，从左向右第一个106-tone RU与该106-tone RU左侧的第一个或者右侧第一个(或者与该106-tone RU连续的一个)52-tone RU合并得到一个第二种Multi-RU。
对于两比特位取值10时，如果指示两个第一种Multi-RU，每个第一种Multi-RU包括的52-tone RU以及26-tone RU的位置可以根据预定义的确定。如果两比特位取值10指示一个为第一种Multi-RU，另一个为第二种Multi-RU(106-tone RU+26-tone RU)，对于第一种Multi-RU和第二种Multi-RU包括的RU位置的确定，也可以按照预定义的规则确定，例如，106-tone RU与52-tone RU分别与距离自己最近的26-tone RU合并，得到一个第一种Multi-RU，一个第二种Multi-RU。对于两比特位取值11时，三个第一种Multi-RU中，每个第一种Multi-RU包括的26-tone RU位置也可以按照上述的预定义的规则进行确定。
也就是说，在本申请实施例中，上述的三种Multi-RU还可以分别指示包括的两个小RU的位置关系。即可以根据不同类型的Multi-RU，还可确定不同类型的Multi-RU包括的两个小RU的位置。换句话说，在本申请实施例中，合并指示除了可以指示一个资源单元的分配方式中的Multi-RU个数，还可以指示每一个Multi-RU包括的两个小RU的位置关系，即合并指示指示的为受限小RU的合并方式。
在本申请另一些可能的实现方式中，两比特位的取值00表示该资源单元的分配方式中无多RU合并，即不存在Multi-RU。两比特位的其他取值表示该资源单元的分配方式存在一个52-tone RU。例如，两比特位的取值01表示在该资源单元的分配方式中，对左起第一个52-tone RU或者第一个106-tone RU与连续或者临近的26-tone RU进行合并，两比特位的取值10表示对左起第二个52-tone RU与连续或者临近的26-tone RU进行合并。两比特位的取值11表示对左起第三个52-tone RU与连续或者临近的26-tone RU进行合并等。与52-tone RU或者106-tone RU连续或者临近的26-tone RU可以理解为：位于52-tone RU或者106-tone RU左侧的第一个或者右侧第一个26-tone RU。换句话说，合并指示除了可以指示一个资源单元的分配方式中的Multi-RU个数，还可以指示每一个Multi-RU包括的两个小RU的位置关系。
对于242-tone内的小RU合并，该合并指示也可以为1比特，例如，资源单元分配子字段包括9bits，其中前8bits用于指示资源单元的分配，后1bits指示一个20MHz的频域资源单元的合并情况。即将8比特索引的资源单元分配子字段扩展为9比特，第9比特为上述的合并指示。在这种情况下，例如，1比特位取值0表示该资源单元的分配方式中无多RU合并，即不存在Multi-RU。1比特位取值1表示该资源单元的分配方式中有一个Multi-RU，这一个Multi-RU可以为：第一种Multi-RU(52-tone RU+26-tone RU)、第二种Multi-RU(106-tone RU+26-tone RU)、或者为第三种Multi-RU(52-tone RU+106-tone RU)。对于一个Multi-RU包括的两个RU的位置可以是预定义的，例如，可以是从左起第一个52-tone RU或者106-tone RU与其连续的(或者最近的)26-tone RU的合并等。也就是说，合并指示除了可以指示一个资源单元的分配方式中的Multi-RU个数，还可以指 示每一个Multi-RU包括的两个小RU的位置关系。
对于跨242-tone的大RU合并，也可以使用2比特长度的合并指示实现指示3个不同的Multi-RU。其中，每一个Multi-RU包括两个或者更多个大RU。例如，将8比特索引的资源单元分配子字段扩展为10比特，其中，前8bits用于指示资源单元的大小以及位置等，后2bits指示该资源单元的合并情况，其中，第九比特和第十比特为上述的合并指示。
一种可能的实现方式为：两比特位取值00表示这个资源单元分配子字段指示的大RU不合并，即不与其他大RU合并。两比特位取值01、10、11分别表示与该资源单元分配子字段指示的大RU不同的合并种类。例如，表8所示的为一例合并指示的不同取值指示的大RU合并的合并方式。
表8
Figure PCTCN2021070851-appb-000009
表8中的第一行每一个RU表示一个资源单元分配子字段指示的大RU(即一种带宽中的RU分配方式)。假设该信令字段包括表8所示的大RU对应的资源单元分配子字段。对于每个资源单元中的合并指示，合并指示位取值为00时来表示这个资源单元分配子字段指示的大RU不合并。合并指示位取值为01表示一种RU合并，将合并指示位取值为01对应的大RU合并后得到一个Multi-RU。合并指示位取值为11表示一种合并，将合并指示位取值为11对应的大RU合并后得到一个Multi-RU。合并指示位取值为10也可以表示一种合并，将合并指示位取值为10对应的大RU合并后得到一个Multi-RU。因此，表8中所示的存在两个Multi-RU，其中一个Multi-RU为(242-tone RU+242-tone RU+996-tone RU)，另一个Multi-RU为(484-tone RU+242-tone RU)。即与某一个合并指示位取值相同的其他合并指示对应的资源单元与该合并指示对应的资源单元进行合并，得到一个Multi-RU。应理解，表8中，一个996-tone RU对应4个RU Allocation subfield，每个RU Allocation subfield中合并指示的取值相同，例如，均为11或者01。一个484-tone RU对应2个RU Allocation subfield，每个RU Allocation subfield中合并指示的取值相同，例如，均为11。
还应理解，如果在利用2比特长度的合并指示的不同取值表示大RU不同的合并类型 时，在大RU对应的合并指示之间之间出现小RU对应的合并指示，则小RU对应的合并指示不会对大RU之间的合并产生影响。即在大RU之间出现小RU对应的合并指示的情况下，可以跳过或者不读取小RU对应的合并指示。
应理解，在本申请实施例中，对于跨242-tone RU的大RU合并，也可以预先定义或者配置可以合并的大RU的个数。进一步的，还可以预先定义或者配置大RU的合并组合或者方式等。在利用2比特长度的合并指示进行大RU合并指示时，可以指示更多个(例如3个、5个等)大RU合并得到一个Multi-RU。也就是说，合并指示可以进一步指示预定义的多个大RU组合方式，即合并指示指示的为受限的大RU的合并方式，对进行合并的大RU的位置以及顺序具有一定的限制。例如，可以预先定义可以合并的大RU的多种合并组合，合并指示可以指示预先定义的多种合并组合中的任意一种大RU的合并组合。
作为另一种可能的实现方式：还可以利用2比特长度的合并指示的不同取值表示大RU在资源单元合并时的不同顺序。例如，两比特位取值00时来表示这个资源单元分配子字段指示的大RU不合并，两比特位取值为01、10、11分别表示需要合并的大RU分别位于合并位置的开头、中间、结尾。例如，表9所示的为一例合并指示位取值指示的RU合并的合并方式。
表9
Figure PCTCN2021070851-appb-000010
在表9所示的例子中，由于在比特位取值“01”与“10”之间存在比特位取值“00”，因此，可以跳过比特位取值“00”对应的大RU，继续向后读取比特位取值“10”以及“11”， 读取到比特位取值“11”时，比特位取值“11”对应的大RU为该Multi-RU包括的最后一个大RU。比特位取值“10”对应的大RU为该Multi-RU包括的第一个大RU。在表9所示的例子中，可以确定存在两个Multi-RU，其中一个Multi-RU为(242-tone RU+242-tone RU+996-tone RU)。另一个Multi-RU为(484-tone RU+242-tone RU)。应理解，表9中，一个996-tone RU对应4个RU Allocation subfield，每个RU Allocation subfield中合并指示的取值相同，例如，均为11或者00。
利用上述的方法，还可以指示出一个Multi-RU包括多个(例如，2个、4个或者更多个)大RU。
还应理解，如果在利用2比特长度的合并指示的不同取值表示大RU在资源单元合并时的不同顺序时，在大RU之间出现小RU对应的合并指示，则小RU对应的合并指示不会对大RU之间的合并产生影响。即在大RU之间出现小RU对应的合并指示的情况下，可以跳过或者不读取小RU对应的合并指示。
可选的，对于跨242-tone的大RU合并，也可以使用1比特长度的合并指示可以实现指示一个Multi-RU包括的多个大RU。即将8比特索引的资源单元分配子字段扩展为9比特，其中前8bits用于指示资源单元的大小以及位置等，后1bits指示该资源单元的合并情况。其中，第九比特上述的合并指示。例如，合并指示取值为0时来表示这个资源单元分配子字段指示的大RU不合并，即不与其他大RU合并。合并指示位取值为1表示与该资源单元分配子字段指示的大RU合并。当然，也可以利用指合并指示取值为1时来表示这个资源单元分配子字段指示的大RU不合并，合并指示为0表示与该资源单元分配子字段指示的大RU合并。在这种情况下需要加以一些限制，如一个Multi-RU为(242-tone RU+484-tone RU)，则这个Multi-RU应当在某一个80MHz之内、并且这个Multi-RU包括的多个RU是预先定好的组合，多个RU的读取顺序为从左到右进行读取等。也就是说，合并指示还可以指示每一个Multi-RU包括的多个大RU的个数以及位置关系，即合并指示可以进一步指示预定义的多个大RU组合方式。
应理解，对于每一个资源单元分配子字段包括的1比特或者多比特的合并指示，可以是用于指示上述的受限的大RU的合并方式，即对于需要合并的大RU的个数、位置以及组合均有一定的限制。例如，可以预先定义可以合并的大RU的多种合并组合，合并指示可以指示预先定义的多种合并组合中的任意一种大RU的合并组合。
例如，如表5所示的合并方式，对于80MHz内的RU合并的不同的组合方式，只需要将需要合并242-tone RU以及484-tone RU对应的资源单元分配子字段最后的指示比特置为1，就可以指示80MHz之内大RU的合并方式，得到不同的Multi-RU。
例如，对于带宽为160MHz时，如表6所示的，表6所示的第一个(第一列)996-tone RU可以为主996-tone RU，即为主80MHz，第二个(第二列)996-tone RU可以为次996-tone RU，即为次80MHz。如果需要合并的996-tone RU在次80MHz，那么在接收设备读取完前面的主80MHz中的RU分布后需要接着读取次996-tone RU对应的资源单元分配子字段中的合并指示，如果合并指示位取值为0则该次996-tone RU不合并，如果合并指示位取值为1则该次996-tone RU合并。通过这种方法可以辨别出Multi-RU包括(242-tone RU+242-tone RU+996-tone RU)与Multi-RU包括(242-tone RU+242-tone RU)这两个不同的Multi-RU。
另外，对于Multi-RU包括(484-tone RU+242-tone RU+242-tone RU+484-tone RU)，由于这几个大RU的位置不同，只需要将这几个需要合并的大RU对应的资源单元分配子字段中的合并指示置1即可。
对于带宽为320MHz时，320MHz带宽内RU的合并方式可以为可以基于996-tone RU的合并方式。例如，当接收设备读取到有三个996-tone RU对应的资源单元分配子字段中的合并指示位取值均为1时，就可以确定出这三个996-tone RU需要合并，得到的一个Multi-RU包括(996-tone RU+996-tone RU+996-tone RU)。
在本申请另一些可能的实现方式中，除了对每一个资源单元分配子字段在其后面添加合并指示来指示该资源单元分配子字段指示的资源单元的合并信息之外，还可以将每一个资源单元分配子字段对应的合并指示统一提取出来，即在该信令字段还存在多资源单元分配字段(Multi RU Allocation field)，该多资源单元分配字段包括每一个资源单元分配子字段对应的合并指示。例如，图11所示的为本申请提供的一例信令字段的示意图，该信令字段还包括多资源单元分配字段，该多资源单元分配字段包括每一个资源单元分配子字段对应的合并指示。合并指示在该多资源单元分配字段的相对位置与合并指示对应的资源单元分配子字段在多个资源单元分配子字段中的相对位置相同。该多资源单元分配字段用于指示信令字段包括的至少一个资源单元分配子字段指示的RU合并情况。具体指示方式与上述的在每一个资源单元分配子字段在其后面添加指示比特的指示方式相同。
例如，对于320MHz带宽而言，该多资源单元分配字段包括的合并指示的长度可以为16比特或者为32比特。
可选的，在本申请实施例中，该多资源单元分配子字段可以在包括在Common字段中。
应理解，在本申请实施例中，对于信令字段中新增的多资源单元分配字段，多资源单元分配字段的构成形式可以有两种。图12所示的为本申请实施例提供的一种多资源单元分配字段的示意图。如图12所示的，多资源单元分配字段与公共字段(Common field)和用户特定字段(User Specific field)一样，划分为多个CC，每个CC携带多资源单元分配字段的一部分的内容。图13所示的为本申请实施例提供的另一种多资源单元分配字段的示意图。如图13所示的，多资源单元分配字段不进行划分，在所有20MHz信道上使用完全重复的内容。即每一个20MHz信道上的多资源单元分配字段均是相同的。
可选的，在本申请一些可能的实现方式中，除了上述的对资源单元分配子字段进行扩展，利用扩展后的资源单元分配子字段包括的合并指示指示资源单元的合并信息之外，还可以不用对资源单元分配子字段进行扩展，而是利用预留的条目来指示资源单元的合并信息。例如，如表1所示的，可以利用预留的多个8比特索引来指示不同的资源单元的分配方式对应的资源单元合并信息。
可选的，在本申请另一些可能的实现方式中，还可以重新定义资源单元分配子字段，即重新构造资源单元分配子字段，重新构造后的一个资源单元分分配子字段对应一个20MHz的频域资源单元的分配以及资源单元的合并情况。也就是说，一个重新构造后资源单元分配子字段指示20MHz内包括的一个或多个资源单元的大小和位置，以及，资源单元的合并情况。通过重新构造资源单元分分配子字段，可以使多RU合并信息直接在公共字段中显示，这样用户在读取公共字段后可以直接知晓新的RU分布顺序以及RU合并方式，因此即使是多RU用户也只需要使用一个用户字段即可确定新的RU分布顺序以及 RU合并方式。
例如。重新构造后的资源单元分配子字段的长度可以为9比特、10比特或者更多比特。本申请在此不作限制。
应理解，重新构造的资源单元分配子字段可以用于指示受限的RU合并，也可以指示非受限的RU合并。例如，对于20MHz内的小RU合并，重新构造的资源单元分配子字段指示的对需要合并的52-tone RU、106-tone RU以及26-tone RU的位置不作限定。例如，需要与52-tone RU或者106-tone RU合并的26-tone RU可以与52-tone RU或者106-tone RU连续的，也可以是不连续的。对于跨242-tone的大RU合并，在相应的20MHz上使用对应配置的重新构造的资源单元分配子字段即可。例如，如果存在80MHz内242tone RU+242tone RU的合并，只需要在对应的两个20MHz处全部使用指示242-tone RU与242-tone RU合并的资源单元分配子字段即可。
可选的，在本申请一些可能的实现方式中，还可以通过对有效RU进行提取并进行指示进而通知接收设备多RU合并信息。也就是说，按照用户读取有效的RU顺序进行所有效的RU的提取以及排序。其中，一个有效RU对应1比特。有效RU集合为{52,106,242,484,996}，集合中的数字表示组成RU的子载波的个数。有效RU将根据在带宽中出现的位置进行关联。例如，如果320MHz中存在20个有效RU，那么将需要至少20比特来对这些RU的合并信息进行指示。
例如，对于242-tone内的小RU合并，每个有效的小RU可以对应1比特，用于指示对应的有效小RU是否与26-tone RU合并得到一个Multi-RU。其中，有效的小RU集合为{52,106}。具体的，在信令字段中的多资源单元分配字段可以包括多个合并指示，每一个合并指示对应一个有效小RU，用于指示这个有效小RU是否与该有效小RU所在的242-tone内的26-tone RU合并。例如，一个有效小RU对应的合并指示位取值为1，则指示该效小RU与该有效小RU所在的242-tone内的26-tone RU合并，某一个有效小RU对应的指示比特位取值为0，指示该效小RU不合并。或者，某一个有效小RU对应的合并指示位取值为0，指示该效小RU与该有效小RU所在的242-tone内的26-tone RU合并，某一个有效小RU对应的合并指示位取值为1，指示该效小RU不合并。
应理解，当某一个合并指示指示该有效小RU与该有效小RU所在的242-tone内的26-tone RU合并时，与该有效小RU合并的26-tone RU可以是与该有效小RU连续的26-tone RU。例如，与该有效小RU左侧的第一个或者右侧第一个26-tone RU合并得到一个Multi-RU。即一个有效小RU对应的合并指示用于指示受限的小RU的合并方式。
可以理解，对于242-tone内的小RU合并，一个242-tone内最多可以包括3个有效小RU。因此，一个242-tone(或者一个资源单元分配子字段)可以对应1比特长度的合并指示，1比特长度的合并指示可以对应一个52-tone RU或者一个106-tone RU。或者，一个242-tone可以对应2比特长度的合并指示，2比特长度的合并指示中每一比特分别指示一个52-tone RU，或者，2比特长度的合并指示中一比特指示一个52-tone RU，另一比特指示一个106-tone RU。或者，一个242-tone可以对应3比特长度的合并指示，3比特长度的合并指示中每一比特分别指示一个52-tone RU。
应理解，对于242-tone内的小RU合并，由于一个RU Allocation subfield指示的RU中可能存在多个有效小RU，因此，不同的RU Allocation subfield对应的合并指示的长度 可以是不同。因此，多资源单元分配字段的长度是可变的。可选的，RU Allocation subfield对应的合并指示的长度可以在Common field中进行指示。或者，也可以设置不同的RU Allocation subfield对应的合并指示的长度为相同。例如，假设每个RU Allocation subfield中最多有x个有效RU合并，则对于存在N个RU Allocation subfield而言，多资源单元分配字段的长度为N×x比特。
对于跨242-tone的大RU合并，即有效大RU的合并指示。其中，有效的大RU集合为{242,484,996}。
可选的，作为一种可能的实现方式，在多资源单元分配字段包括合并指示中，一个有效大RU可以对应2比特长度的合并指示，该2比特长度的合并指示的不同取值表示该有效大RU在资源单元合并时的不同顺序。例如，合并指示位取值为00时来表示该有效大RU不合并，合并指示位取值为01、10、11分别表示该有效大RU位于合并位置的开头、中间、结尾。
可选的，作为一种可能的实现方式，在多资源单元分配字段包括合并指示中，一个有效大RU对应2比特长度的指示比特。该2比特长度的指示比特的不同取值表示有效大RU在资源单元合并时的不同合并状态。例如，合并指示位取值为00时来表示该有效大RU不合并。合并指示位取值为01、10和11分别表示该有效大RU不同的合并种类，其中，相同取值的合并指示对应的有效大RU之间进行合并。
在本申请一些可能的实现方式中，对于跨242-tone的大RU合并，即有效大RU的合并指示，一个有效大RU也可以对应1比特长度的指示比特，用于指示这个有效大RU是否合并。例如，合并指示位取值为0时来表示该有效大RU不合并，合并指示位取值为1表示该有效大RU合并。当然，也可以利用合并指示为1时来表示指示该有效大RU不合并，合并指示位取值为0表示该有效大RU合并。在这种情况下，需要预先定义一个Multi-RU包括的多个大RU的组合以及位置等。
例如，表10所示的为一例合并指示与有效大RU之间的对应关系的示意图。
表10
Figure PCTCN2021070851-appb-000011
在表10所示的例子中，合并指示位取值为0表示该合并指示对应的有效大RU不合并，合并指示位取值为1表示该合并指示对应的有效大RU合并。在这种情况下，如果不加以约束会产生一定的混淆，如表10所示的例子中难以区分是996-tone RU+484-tone RU+242-tone RU合并成一个Multi-RU，还是242-tone RU+242-tone RU+996-tone RU合并成一个Multi-RU，因此，可以按照预先定义或者配置大RU的合并组合或者方式等。例如， 选择从左到右出现的预定好的组合则可以解决该问题。假设预先设定好的大RU合并组合为242-tone RU+242-tone RU+996-tone RU，即可以确定表10中所示的Multi-RU包括242-tone RU+242-tone RU+996-tone RU。应理解，表10中，一个996-tone RU对应4个RU Allocation subfield，每个RU Allocation subfield对应的合并指示的取值相同，例如，均为1或者0。一个484-tone RU对应2个RU Allocation subfield，每个RU Allocation subfield中合并指示的取值相同，例如，均为1。
也就是说，对于每一个有效大RU对应的1比特或者多比特的合并指示，可以是用于指示上述的受限的大RU的合并方式，即对于需要合并的大RU的个数、位置以及组合均有一定的限制。例如，可以预先定义可以合并的大RU的多种合并组合，合并指示可以指示预先定义的多种合并组合中的任意一种大RU的合并组合。
本申请提供的资源单元合并指示的方法，通过对有效RU进行了提取，并按照有效RU出现的位置对指示有效RU合并与否的合并指示进行排列，可以实现多RU合并信息进行有效指示。
应理解，除了将有效RU对应的合并指示统一设置在信令字段中的多资源单元分配字段中之外，可选的，还可以对资源单元分配子字段进行扩展，将每个资源单元分配子字段对应的有效RU的合并指示设置在对应的资源单元分配子字段后面。例如，扩展后的资源单元分配子字段可以为9比特、10比特或更多的比特等，利用扩展的1比特或者多比特分别指示有效RU的合并情况。
可选的，在本申请一些可能的实现方式中，除了上述对于信令字段中的公共字段进行改进实现通知多RU的合并之外，还可以对用户字段进行改进实现通知多RU的合并。
作为一种可能的实现方式，可以将不同用户字段(User Field)中的STA ID设置为相同。这样一个用户可以知道对应的多个RU被分配给自己，从而实现RU合并信息的告知；
作为另一种可能的实现方式，由于一个Multi-RU是由多个连续的或者不连续的RU合并组成。组成该Multi-RU的多个连续的或者不连续的RU可以分配给一个用户，这多个RU分别对应的STA ID是相同的，因此，可以修改这些STA ID相同的用户字段中除最后一个用户字段外其他用户字段中的信息。例如，可以在这些STA ID相同的用户字段中，在除过最后一个用户字段外的其他每个用户字段中，均利用9比特的指示信息指示属于该用户(或者该用户对应)的下一个RU的绝对位置信息或者相对位置信息。通过这种指示，可以使多资源单元用户在读取到第一个RU后直接获知下一个RU的位置，在一定程度上节约能耗。
作为又一种可能的实现方式，由于一个Multi-RU是由多个连续的或者不连续的RU合并组成。组成该Multi-RU的多个连续的或者不连续的RU可以分配给一个用户，这多个RU分别对应的STA ID是相同的。因此，在本申请实施例中，可以在多个STA ID相同的用户字段除过最后一个用户字段外的其他每个用户字段中均利用8比特的指示信息指示属于该用户的下一个RU的绝对位置信息或者相对位置信息，即指示组成Multi-RU的多个RU的位置以及大小等。
例如，在多个STA ID相同的用户字段除过最后一个用户字段外的其他每个用户字段中，可以通过指示索引信道编号与RU出现次序这两个信息对与该用户字段对应的RU的下一个需要合并的RU位置进行灵活标识。
具体的，当STA确定资源单元分配子字段后，STA可以利用4比特指示确定需要与当前自己所处的RU合并的RU所处的信道(4比特可以穷尽16个信道)，同时，STA可以再用另外的4比特指示每个信道中具体的RU(每个242-tone内最多有9个RU)位置。因此，可以用8比特灵活的指示下一个需要合并的RU所处的位置。换句话说，在多个STA ID相同的用户字段除过最后一个用户字段外的其他用户字段中，可以利用8比特长度的指示字段去指示与当前用户字段需要合并的下一个RU的位置信息。从而确定需要与当前用户所处的RU合并的RU信息。
例如，当一个Multi-RU由两个RU合并组成时，两个RU对应的两个用户字段的STA ID相同，因此，在第一个用户字段中可以利用8比特长度的指示字段去指示与当前用户字段需要合并的下一个RU的位置信息便可以确定该Multi-RU。
又例如，当一个Multi-RU由3个RU合并组成时，3个RU对应的三个用户字段的STA ID相同，在第一个用户字段和第二个用户字段均可以存在8比特的指示字段，分别用于指示需要合并的第二个RU和第3个RU的位置，这样便可以确定该Multi-RU。类似的，对于一个Multi-RU由更多个RU合并组成时，只需要在除过最后一个RU之外的其他RU对应的用户字段设置8比特的指示字段，便可以确定Multi-RU。
应理解，利用用户字段中的8比特指示字段可以指示非受限的合并方式，或者可以指示受限的合并方式。并且，可以指示对于20MHz内的小RU合并，或者还可以指示跨242-tone的大RU合并。
在另一些可能的实现方式中，在多个STA ID相同的用户字段中，除过最后一个用户字段外的其他每个用户字段中，还可以利用4比特指示受限的RU合并方式RU的位置信息。假设242-tone RU内的小RU不支持跨242-tone合并，对于20MHz内的小RU合并，由于每个242-tone内最多有9个RU，则4比特完全可以指示下一个合并RU的位置。当然，对于20MHz内的小RU合并，3比特完全也可以指示下一个合并RU的位置。因此，对于20MHz内的小RU合并，在多个STA ID相同的用户字段中，除过最后一个用户字段外的其他用户字段中，可以利用3比特或者4比特指示需要与当前用户所处(或者所对应)的RU合并的RU信息。
对于跨242-tone RU的大RU合并，由于小RU不能跨242-tone与大RU合并，因此可以用一定数目的指示比特指示大RU的类型，并另外用一定数目指示比特指示大RU位置，通过指示大RU类型以及大RU位置这两个信息对需要合并的大RU进行指示。其中，大RU类型指的是大RU为242-tone RU、484-tone RU、或者是996-tone RU。例如，在多个STA ID相同的用户字段中，除过最后一个用户字段外的其他每个用户字段中，均可以利用2比特指示需要与当前用户所处的大RU合并的RU类型，例如，2比特位取值为00、01、10分别指示的大RU的类型为242-tone RU、484-tone RU、996-tone RU，用另外的2比特用另外的2比特指示是后面第几个该类型的大RU。
也就是说，多个STA ID相同的用户字段中，除过最后一个用户字段外的其他每个用户字段中，均可以利用3比特或者4比特指示需要与当前用户所处的RU合并的大RU信息。例如，当一个Multi-RU由3个大RU合并组成时，在3个大RU对应的3个用户字段中的第一个和第二个用户字段中可以存在4比特的指示字段，用于指示需要合并的第2个和第3个大RU的位置，这样便可以确定该Multi-RU。类似的，对于一个Multi-RU由更 多个RU合并组成时，只需要在除过最后一个RU之外的其他RU对应的用户字段均设置4比特的指示字段，便可以确定Multi-RU。
例如，如表5所示的组合方式1形成的Multi-RU(242-tone RU+242-tone RU)，在第一个242-tone RU对应的用户字段中可以存在4比特的指示比特，该四比特位取值为0010表示，其中，前面两个比特位取值00表示下一个需要合并的RU为242-tone RU类型，后面两个比特位取值10表示是在当前RU之后的第三个。用户结合已知的资源单元分配子字段信息，便可以得知具体的RU位置，从而确定该Multi-RU。对第二个242-tone RU对应的用户字段可以不用进行修改。因此，4比特长度的指示比特可以对受限的多RU合并方式进行指示。
还应理解，如果需要进一步增加指示的灵活性，可以进一步增加使用的比特数目。例如，在多个相同的用户字段除过最后一个用户字段外的其他每个用户字段中，利用其他长度的指示比特指示与当前用户所处的RU合并的大RU信息。
可选的，在本申请实施例中，无论对于大RU的合并还是小RU的合并，对于需要合并的多个RU对应的多个用户字段，由于多个用户字段中的STA ID相同，因此，还可以在这多个用户字段中的每个用户字段中(包括最后一个用户字段)添加用于指示该用户字段是否为最后一个用户字段的指示比特，该指示比特用于指示该用户字段是否为最后一个需要合并的RU对应的用户字段，这样可以避免用户以为最后一个用户字段还包括指示下一个RU的位置的信息。例如，利用一比特的指示，在除过最后一个用户字段外的其他用户字段这1比特取值为1，用于指示对应的用户字段不是最后一个用户字段，在最后一个用户字段中这1比特取值为0，用于指示对应的用户字段为最后一个用户字段。
需要说明的是，由于RU的位置与用户字段在用户特定字段中的位置存在对应关系，因此，指示RU位置也是指示了RU对应的用户字段的位置。
可选的，在本申请实施例中，对于需要合并的多个RU对应的多个用户字段，由于这多个用户字段中的STA ID相同，因此，还可以在这多个用户字段中的每个用户字段中(包括最后一个用户字段)，添加用于指示需要合并的RU的个数的指示比特，用于指示需要合并的RU的个数。例如，当需要合并的RU的个数为4个时，该指示比特可以为2比特长度。每个用户字段中的该指示比特取值相同，这样可以使得用户更加准确的都读取需要合并的RU的个数。
在本申请另一些可能的实现方式中，在该信令字段还可以包括多资源单元分配字段(Multi RU Allocation field)，在该多资源单元分配字段中包括多个位置信息指示子字段，一个位置信息指示子字段用于指示一个需要合并为Multi-RU的RU位置。其中，多个位置信息指示子字段的两个或者更多个为一组，一组位置信息指示子字段指示的多个RU合并为一个Multi-RU。用户通过读取资源单元分配子字段的基础上，结合多个位置信息指示比特，根据自己出现在User Specific field中的次序可以知晓自己所分配的RU，进而可以在已得到RU分配形式的基础上进一步取得多RU合并的信息。利用这种方式，用户仍按照RU出现顺序进行排序即可，每个用户仅在User Specific field出现一次，通过查找其所在的位置，就可以获得被分配的RU等信息。
具体的，作为一种可能的实现方式，下面结合图14所示的为例进进行说明，图14所示的本申请提供的一例信令字段的示意图，该信令字段还包括多资源单元分配字段，该多 资源单元分配字段包括多个位置信息指示子字段，一个位置信息指示子字段用于指示一个需要合并为Multi-RU的RU位置。相邻位置信息指示字段指示的RU需要进行合并。例如，图14所示的例子中，多资源单元分配字段包括6个位置信息指示子字段，一个位置信息指示子字段用于指示一个需要合并为Multi-RU的RU位置。
假设：位置信息指示子字段1至位置信息指示子字段4指示的3个RU需要合并为一个Multi-RU，位置信息指示子字段5和位置信息指示子字段6指示的2个RU需要合并为另一个Multi-RU。如图15所示，图15所示的每一个长方形中表示一个RU，长方形中的数字表示该RU对应第几个用户(或者用户字段出现的顺序)，每一行长方形对应一个20MHz带宽。假设，位置信息指示子字段1指示位置1，表示第一行第一个长方形，位置信息指示子字段2指示位置2，表示第三行第二个长方形，并且，可以将位置1和位置2上的RU进行合并。位置信息指示子字段3也指示位置2，即位置信息指示子字段2和位置信息指示子字段2均指示位置2上的RU。位置信息指示子字段4指示位置3，表示第三行第三个长方形。并且，位置3只对应一个位置信息指示子字段4，可以确定位置3上的RU为一个Multi-RU包括的最后一个RU，只需要将位置信息指示子字段4指示的RU和前一个位置信息指示子字段(位置信息指示子字段3)指示的RU进行合并。因此，可以确定该Multi-RU包括：位置信息指示子字段1指示的RU+位置信息指示子字段2或3指示的RU+位置信息指示子字段4指示的RU。即对于一个Multi-RU包括三个RU而言，中间的RU对应两个位置信息指示子字段。即需要利用4个位置信息指示子字段指示3个RU的合并。
进一步的，位置信息指示子字段5指示位置4，表示第二行第二个长方形，位置信息指示子字段6指示位置5，表示第二行第三个长方形。如果后续没有其他的位置信息指示子字段6也指示位置5，则可以确定另外一个Multi-RU包括：位置信息指示子字段5指示的RU+位置信息指示子字段6指示的RU。用户根据自己出现在User Specific field中的次序可以确定自己所分配的RU，进而可以在已得到RU分配形式的基础上进一步取得多RU合并的信息。例如在图13所的例子中，位置1至位置4对应的3个RU合并为一个Multi-RU，为用户1使用。位置5至位置6对应的2个RU合并为另一个Multi-RU，为用户10使用。
可选的，每一个位置信息指示子字段的长度可以为4比特、8比特、9比特或者其他长度。用于指示242-tone RU内的小RU合并以及跨242-tone RU的大RU合并。可选的，242-tone RU内的小RU合并以及跨242-tone RU的大RU合并均可以是不受限的RU合并。
可选的，作为另一种可能的实现方式，可以在每一个位置信息指示子字段添加1比特的组指示比特，组指示比特位取值相同的多个位置信息指示子字段指示的RU可以合并为一个Multi-RU。例如，对于图13所示的，如果一个Multi-RU由3个RU组成，则可以在这个3个RU对应的3个位置信息指示子字段中分别添加一比特的组指示比特，并且，3个RU对应的组指示比特位取值相同。这样就可以指示这3个RU需要合并为一个Multi-RU，而不同通过重复指示一个RU位置的方式去确定哪些RU需要合并为一个Multi-RU可以节省需要的位置信息指示子字段个数。即可以利用3个位置信息指示子字段指示3个RU的合并。不会出现同一个位置上的RU对应两个位置信息指示子字段。用户根据自己出现在User Specific field中的次序可以确定自己所分配的RU，进而可以在已得到RU分配形式的基础上进一步取得多RU合并的信息。并且，同一用户只需要在User  Specific field中出现一次。
应该理解，在本申请实施例中，多资源单元分配字段的长度可以在公共字段中指示。并且，多资源单元分配字段包括多个位置信息指示子字段可以在CC1、CC2中全部存在，也可以采用CC1存在一部分，CC2存在存另一部分的方式。本申请实施例在此不作限制。
可选的，在本申请另一些可能的实现方式中，对于每80MHz中间的一个中心26-tone RU(Center 26-tone RU)的合并情况。该中心26-tone RU也可以和其他的RU进行合并得到一个Multi-RU。该中心26-tone RU是否存在与Common field中的Center 26-tone RU字段的取值有关，该字段为1比特位，1比特位取值为1时表示存在中心26-tone RU，1比特位取值为0时表示不存在中心26-tone RU。
作为一种可能的实现方式，可以将Center 26-tone RU字段扩展多个比特，例如，扩展为2比特，其中，2比特位取值为00表示对应80MHz频带不存在该中心26-tone RU，2比特位取值为01表示对应80MHz频带存在该中心26-tone RU，但该中心26-tone RU不合并，即不与其他的RU合并，2比特位取值为10、11分别表示对应80MHz频带存在该中心26-tone RU，且该中心26-tone RU需要与其他RU合并。
例如，2比特位取值为10表示该中心26-tone RU与右边的242-tone范围内的连续RU进行合并得到一个Multi-RU。2比特位取值为11表示该中心26-tone RU与左边的242-tone范围内的连续RU进行合并得到一个Multi-RU。
又例如，2比特位取值为10表示该中心26-tone RU与右边的242-tone范围内的与该中心26-tone RU最接近的RU进行合并得到一个Multi-RU。2比特位取值为11表示该中心26-tone RU与左边的242-tone范围内的与该中心26-tone RU最接近的RU进行合并得到一个Multi-RU。
其中，与该中心26-tone RU连续的RU可以理解为该中心26-tone RU前一个或者后一个RU，与该中心26-tone RU最接近的RU可以是与该中心26-tone RU连续的RU，也可以不是与该中心26-tone RU连续的RU，例如，与该中心26-tone RU最接近的RU可能是在间隔多个RU后的在该中心26-tone RU坐标或者右边的RU。
应理解，在本申请实施例中，还可将Center 26-tone RU字段扩展多个比特扩展为更多个比特，用于指示与该Center 26-tone RU更多的合并状态。
还应理解，与中心26-tone RU最近或者连续的242-tone范围内RU可以是52-tone RU、106-tone RU、或者242-tone RU等。
作为另一种可能的实现方式，还可以将用于指示Center 26-tone RU是否与多RU合并的合并指示设置在该中心26-tone RU对应的User field中，即修改该中心26-tone RU对应的User field。并且，所有的用户都需要读取该中心26-tone RU对应的User field，确定中心26-tone RU对应的User field中的STA ID和自己的ID是否相同。如果相同，表示该中心26-tone RU需要当前用户字段对应的RU进行合并。
应理解，在本申请的各个实施例中，第一、第二等只是为了表示多个对象是不同的。例如第一字段和第二字段只是为了表示出不同的字段。而不应该对字段的本身和数量等产生任何影响，上述的第一、第二等不应该对本申请的实施例造成任何限制。
还应理解，本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便，不应构成特别的限定，各种方式、类别、情况以及实施例中的特征在不矛盾的情况下 可以相结合。
还应理解，在本申请的实施例中涉及的各种数字编号仅为描述方便进行的区分，并不用来限制本申请的实施例的范围。上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
还应理解，上述只是为了帮助本领域技术人员更好地理解本申请实施例，而非要限制本申请实施例的范围。本领域技术人员根据所给出的上述示例，显然可以进行各种等价的修改或变化.例如，上述方法200、中某些步骤可以是不必须的，或者可以新加入某些步骤等。或者上述任意两种或者任意多种实施例的组合。这样的修改、变化或者组合后的方案也落入本申请实施例的范围内。
还应理解，上文对本申请实施例的描述着重于强调各个实施例之间的不同之处，未提到的相同或相似之处可以互相参考，为了简洁，这里不再赘述。
还应理解，本申请实施例中，“预定义”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。

还应理解，以上装置中单元的划分仅仅是一种逻辑功能的划分，实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且装置中的单元可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分单元以软件通过处理元件调用的形式实现，部分单元以硬件的形式实现。例如，各个单元可以为单独设立的处理元件，也可以集成在装置的某一个芯片中实现，此外，也可以以程序的形式存储于存储器中，由装置的某一个处理元件调用并执行该单元的功能。这里该处理元件又可以称为处理器，可以是一种具有信号处理能力的集成电路。在实现过程中，上述方法的各步骤或以上各个单元可以通过处理器元件中的硬件的集成逻辑电路实现或者以软件通过处理元件调用的形式实现。
在一个例子中，以上任一装置中的单元可以是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个专用集成电路(application specific integrated circuit，ASIC)，或，一个或多个数字信号处理器(digital signal processor，DSP)，或，一个或者多个现场可编程门阵列(field programmable gate array，FPGA)，或这些集成电路形式中至少两种的组合。再如，当装置中的单元可以通过处理元件调度程序的形式实现时，该处理元件可以是通用处理器，例如中央处理器(central processing unit，CPU)或其它可以调用程序的处理器。再如，这些单元可以集成在一起，以片上系统(system-on-a-chip，SOC)的形式实现。

图22是本申请实施例提供的一种网络设备的结构示意图。用于实现以上实施例中网络设备(即发送设备)的操作。如图22所示，该网络设备包括：天线1001、射频装置1002、基带装置1003。天线1001与射频装置1002连接。在上行方向上，射频装置1002通过天线1001接收终端发送的信息，将终端设备发送的信息发送给基带装置1003进行处理。在下行方向上，基带装置1003对终端的信息进行处理，并发送给射频装置1002，射频装置1002对终端设备的信息进行处理后经过天线1001发送给终端。
基带装置1003可以包括一个或多个处理元件10031，例如，包括一个主控CPU和其它集成电路。此外，该基带装置1003还可以包括存储元件10032和接口10033，存储元件10032用于存储程序和数据；接口10033用于与射频装置1002交互信息，该接口例如为通用公共无线接口(common public radio interface，CPRI)。以上用于网络设备的装置可以位于基带装置1003，例如，以上用于网络设备的装置可以为基带装置1003上的芯片，该芯片包括至少一个处理元件和接口电路，其中处理元件用于执行以上网络设备执行的任一种方法的各个步骤，接口电路用于与其它装置通信。在一种实现中，网络设备实现以上方法中各个步骤的单元可以通过处理元件调度程序的形式实现，例如用于网络设备的装置 包括处理元件和存储元件，处理元件调用存储元件存储的程序，以执行以上方法实施例中网络设备执行的方法。存储元件可以为处理元件处于同一芯片上的存储元件，即片内存储元件，也可以为与处理元件处于不同芯片上的存储元件，即片外存储元件。
可选的，在本申请另一些可能的实现方式中，对于242-tone内的小RU合并，在20MHz内，当合并指示为2比特时，两比特位的取值00表示该资源单元的分配方式中无多RU合并，即不存在Multi-RU。两比特位的取值01表示第2个52-tone RU与第2个26-tone RU合并为一个Multi-RU，也即第2个52-tone RU与其左边相邻的26-tone RU合并为一个Multi-RU。例如，如图23所示的，排序按照20MHz内频域从低到高的顺序，20MHz可以包括有9个26-tone RU。或者，20MHz可以包括有4个52-tone RU，或者，20MHz可以包括有2个106-tone RU。第2个26-tone RU位于9个26-tone RU中的第2个，第2个52-tone RU位于4个52-tone RU中的第2个。在图23中，第一行标记为第一种填充图案的26-tone RU即为上述的第2个26-tone RU。第二行标记为第一种填充图案的52-tone RU即为上述的第2个52-tone RU。或者，两比特位的取值01表示第1个106-tone RU与20MHz内的中间的26-tone RU(即第5个26-tone RU)合并为一个Multi-RU。在图23中，第三行标记为第三种填充图案的106-tone RU即为上述的第1个106-tone RU，第一行标记为第二种填充图案的26-tone RU即为上述的第5个26-tone RU(20MHz内的中间的26-tone RU)。图23中，具有同种填充图案的RU可以合并为一个Multi-RU。
当两比特位的取值10表示第3个52-tone RU与第8个26-tone RU合并为一个Multi-RU，也即第3个52-tone RU与其右边相邻的26-tone RU合并为一个Multi-RU，第3个52-tone RU位于4个52-tone RU中的第3个，第8个26-tone RU位于9个26-tone RU中的第8个，在图23中，第二行标记为第三种填充图案的52-tone RU即为上述的第3个52-tone RU，第一行标记为第三种填充图案的26-tone RU即为上述的第8个26-tone RU。
或者，两比特位的取值10表示：第2个106-tone RU与20MHz内的中间的26-tone RU(即第5个26-tone RU)合并为一个Multi-RU。在图23中，第三行标记为第四种填充图案的106-tone RU即为上述的第2个106-tone RU，20MHz内中间的26-tone RU为第一行标记为第二种填充图案的26-tone RU。
当两比特位的取值11表示：存在两比特位的取值01指示的RU合并以及两比特位的取值10指示的RU合并。
应理解，在本申请实施例中，两比特位的取值表示的含义还可以互换，例如，两比特位的取值01指示的内容可以和两比特位的取值10互换，或者，两比特位的取值01指示的内容可以和两比特位的取值11互换，或者，两比特位的取值10指示的内容可以和两比特位的取值11互换。也就是说，上述的例子中的两比特位的具体取值不应该对本申请实施例造成任何限制。
在40MHz上时，由于40MHz带宽大致相当于20MHz的子载波分布的复制，如图24所示的，由于小RU之间不进行跨20MHz的合并，因此，在每个20MHz的信道上，都可以按照图23所示的合并指示以及合并方式进行合并。
类似的，对于80MHz、160MHz以及320MHz的带宽，由于小RU之间不进行跨20MHz的合并。在每个20MHz的信道上，都可以按照图23所示的合并指示以及合并方式进行合并。
在另一种实现中，网络设备实现以上方法中各个步骤的单元可以是被配置成一个或多个处理元件，这些处理元件设置于基带装置上，这里的处理元件可以为集成电路，例如：一个或多个ASIC，或，一个或多个DSP，或，一个或者多个FPGA，或者这些类集成电路的组合。这些集成电路可以集成在一起，构成芯片。
网络设备实现以上方法中各个步骤的单元可以集成在一起，以片上系统的形式实现，例如，基带装置包括该SOC芯片，用于实现以上方法。
上述各个装置实施例中的终端设备与网络设备可以与方法实施例中的接收设备和发送设备完全对应，由相应的模块或者单元执行相应的步骤，例如，当该装置以芯片的方式实现时，该接收单元可以是该芯片用于从其他芯片或者装置接收信号的接口电路。以上用于发送的单元是一种该装置的接口电路，用于向其他装置发送信号，例如，当该装置以芯片的方式实现时，该发送单元是该芯片用于向其他芯片或者装置发送信号的接口电路。
