具体实施方式
下面将参照附图更详细地描述本公开的实施例。虽然附图中显示了本公开的某些实施例，然而应当理解的是，本公开可以通过各种形式来实现，而且不应该被解释为限于这里阐述的实施例，相反提供这些实施例是为了更加透彻和完整地理解本公开。应当理解的是，本公开的附图及实施例仅用于示例性作用，并非用于限制本公开的保护范围。
在本公开的实施例的描述中，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”。术语“基于”应当理解为“至少部分地基于”。术语“一个实施例”或“该实施例”应当理解为“至少一个实施例”。术语“第一”、“第二”等等可以指代不同的或相同的对象。
在本公开的上下文中，术语“无线通信系统”例如可以为广域网系统或者为无线局域网(WLAN)系统。该无线通信系统可以支持多种WLAN通信协议，例如电气和电子工程师协会(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。为描述方便，本公开实施例以WLAN为例进行说明。WLAN中可以包括多个基本服务集(Basic Service Set，BSS)，基本服务集的节点包括接入点类的站点和非接入点类的站点(Non Access Point Station，Non-AP STA)。
术语“接入点(Access Point，AP)”也可以称为接入点类的站点。AP可以为具有无线收发功能的装置，可以为站点提供服务。AP也可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，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络和无线网络的桥梁，其主要作用是将各个STA连接到一起，然后将无线网络接入有线网络。可选地，AP可以是带有无线保真(Wireless Fidelity，Wi-Fi)芯片的终端设备或者网络设备，例如，AP可以是通信服务器、路由器、交换机或网桥等。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。
术语“站点(STA)”可以是具有无线收发功能的装置，其可以基于接入点接入无线局域网。STA可以是无线通信芯片、无线传感器或无线通信终端。例如，STA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)。STA可以为无线通信芯片、无线传感器或无线通信终端。例如STA为支持Wi-Fi通信功能的移动电话、支持Wi-Fi通信功能的平板电脑、支持Wi-Fi通信功能的机顶盒、支持Wi-Fi通信功能的智能电视、支持Wi-Fi通信功能的智能可穿戴设备、支持Wi-Fi通信功能的车载通信设备和支持Wi-Fi通信功能的计算机等。可选地，STA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。
术语“正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)”是当前无线通信的基本传输方式，其被广泛应用于各种无线通信系统。不仅如此，OFDM也进一步应用到固网传输，比如光纤、铜绞线、电缆等传输方式。OFDM的基本原理是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，这一方面能保证形成多路并行且互不干扰的通路，同时又能提升系统的频率利用效率。进一步的，由于OFDM具有以上特性，如果将OFDM的互不干扰的子载波分配给多个用户，就能利用OFDM来实现多用户的接入或者数据传输，这就是正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)。采用OFDMA可以实现多用户数据的并行传输，是提高数据传输并发性的有效方式。
术语“多输入多输出(Multiple Input Multiple Output，MIMO)技术”是如下技术，其可以利用多天线产生额外的空间自由度从而成倍地提高系统的吞吐量，有效地提高通信系统的速率。另外，发送端可以通过多个空间流向多个用户进行数据发送，从而实现多用户(Multiple-User，MU)数据的并行传输，提高数据传输的并发性，也可称为MU-MIMO。
WLAN系统的802.11各个标准版本在不断演进，从802.11a/b/g开始，历经802.11n，802.11ac，802.11ax到802.11be。在802.11n之前只支持单用户单输入单输出(Single User Single Input Single Output，SU-SISO)，802.11n开始支持单用户多输入多输出(Single User Multiple Input Multiple Output，SU-MIMO)，并且从802.11ac和802.11ax开始支持MU-MIMO。在802.11ax之前，802.11标准支持OFDM传输。从802.11ax开始，引入了OFDMA技术，整个带宽可以被分为一个或多个资源单元(Resource Unit，RU)。目前正在研究中的802.11be支持MU-MIMO和OFDMA，其中定义有极高吞吐量多用户物理层协议数据单元(Extremely High Throughput Multiple User Physical Protocol Data Unit，EHT MU PPDU)。
随着WLAN 802.11的演进，其允许传输的带宽也逐渐发生了变化。802.11a/g标准允许传输的带宽为20MHz，802.11n标准允许传输的带宽为20MHz或40MHz，802.11ax允许传输的带宽为20MHz，40MHz，80MHz或160MHz，802.11be标准支持的带宽被扩展到320MHz，从而能显著提升峰值吞吐量，进一步提升传输速率。
图1示出了针对320MHz带宽的信道划分100的示意图。具体地，图1中示出的是非授权国际信息基础设施(the Unlicensed National Information Infrastructure，U-NII)无线电频带(radio band)在6GHz频段中的信道划分。图1中示出了80MHz 110，160MHz 120，320MHz-1130和320MHz-2 140。可理解的是，为了有效利用信道，被设计有两种320MHz信道，分别是信道中心频率为31/95/159的320MHz-1和中心频率为63/127/191的320MHz-2，在图1中分别示出为130和140。
可理解的是，图1针对的是320MHz带宽，在其他场景下，该带宽可以为其他值，例如 在未来可能发展的演进的极高吞吐量中可能将带宽扩展到更大，如480MHz、640MHz或其他值等。
在WLAN中，信道通常分为主信道和从信道。在整个带宽范围(如320MHz)内，AP会选取一个20MHz信道为主信道。包含该主信道的80MHz信道会被称之为主80MHz信道，其他80MHz信道为非主80Mhz信道，或者称为从80Mhz信道或次80Mhz信道。包含该主信道的160MHz信道被称之为主160MHz信道，其他的160MHz信道为非主160MHz信道，或称为从160MHz信道或次160MHz信道。示例性地，主80MHz信道(或者主160MHz信道)的位置可以是AP在建立基本服务集(BSS)时所选择的，AP可以通过信标帧以广播的形式进行发送，以通知所有的STA。
在目前的多用户传输中，AP可以在PPDU中携带多个STA的数据进行发送。STA接收到数据之后，可以基于数据帧中携带的触发的响应调度(Triggered Response Scheduling，TRS)信息，向AP发送确认帧。但是当带宽大于160MHz(如320MHz)时，STA无法确定在哪个信道上传输确认帧，因此目前的方案不够完善。
本公开的实施例提供了一种信息传输方案。该方案能够基于数据帧占用的发送资源块以及数据帧中的RU分配信息来确定使用哪个信道上的哪个或哪些RU来发送确认帧，从而确保了传输的正确性。以下通过图2至图12更加详细地描述根据本公开的实施例。
图2示出了本公开实施例可实现在其中的通信系统200的一个示意图。如图2所示，该系统200包括发送设备201和接收设备202，发送设备201和接收设备202之间可以通过无线网络进行通信。
图2中所示的发送设备201可以为AP或STA，接收设备202可以为AP或STA。并且可理解，尽管图2中仅示出了单个发送设备201和单个接收设备202，但是本公开对此不限定，例如，系统200可以包括多个接收设备202，并且发送设备201可以与多个接收设备202进行通信，或其他场景等，本公开中不再罗列。
图3示出了本公开实施例可实现在其中的通信系统300的另一个示意图。图3示出了两个AP，即AP 301和AP 302。图3还示出了三个站点，即STA 321、STA 322和STA 323。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。本公开的实施例可以应用在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。例如，结合图3，可以是AP 301与AP 302之间的通信，可以是STA 322与STA 323之间的通信，可以是AP 301与STA 321之间的通信或者AP 301与STA 322之间的通信等。应注意，图3仅是示意性的，不应解释为对本公开实施例的限制。
为了便于描述，以下将AP 301和AP 302统称为AP 30，并且以下将STA 321、STA 322和STA 323统称为STA 32。
还应理解的是，图2和图3仅仅是本公开实施例可实现在其中的通信系统的示意图。通信系统200和通信系统300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等。另外，本公开实施例对该系统200所包括的发送设备201和接收设备202的数量、系统300所包括的AP 30和STA 32的数量不作限定。
图4示出了根据本公开的实施例的信息传输过程400的一个示意交互图。过程400涉及发送设备201和接收设备202。可以理解，图4中示出的通信过程仅为示例性的，而非限制性的。本公开的实施例可以包括图4中未示出的交互信令，或者省略图4中示出的某些信令。
在过程400中，发送设备201可以首先向接收设备202发送410数据帧。
示例性地，本公开实施例中的数据帧可以占用发送资源块，且发送资源块的带宽可以大于带宽阈值。换句话说，本公开实施例中的数据帧的带宽大于带宽阈值。在一些示例中，数据帧中可以包括单个MU PPDU，该单个MU PPDU的带宽大于带宽阈值。在另一些示例中，数据帧中可以包括多个MU PPDU，例如可以是多个MU PPDU被聚合而成的聚合PPDU，且该聚合PPDU的带宽大于带宽阈值。举例来说，带宽阈值可以为160MHz或者可以为320MHz或者其他值，本公开对此不限定。
可理解的是，数据帧的带宽应当不大于总的可用带宽(简称为总带宽)，以图1为例，总带宽为320MHz。在其他场景下，总带宽也可以为其他值，例如480MHz，本公开对此不限定。
在本公开的实施例中，数据帧可以实现单独的OFDMA传输，或者，可以实现单独的MU-MIMO传输，或者，可以实现OFDMA和MU-MIMO的混合传输。在一些实施例中，可以在数据帧的物理层格式的特定字段中指定该传输的类型，其中特定字段例如可以是极高吞吐量信令字段(Extremely High Throughput Signal Field，EHT-SIG)。
在本公开的实施例中，可以定义多个不同的RU类型，并可以将整个带宽以RU类型为单位进行划分，RU类型可以通过子载波(tone)的形式表示该RU类型所占用的带宽。一般地，20MHz带宽内有242个子载波，40MHz带宽内有484个子载波，80MHz带宽内有996个子载波。
RU类型可以包括：26-tone RU，52-tone RU，106-tone RU，242-tone RU，484-tone RU，996-tone RU，2×996-tone RU，4×996-tone RU等。
针对不同的RU类型，在各个带宽下所能支持的最大数量是不同的，如下表1所示。在下面的表1中虽然未示出4×996-tone RU，但是可理解，4×996-tone RU对应的是320MHz。
表1
RU类型 20MHz带宽 40MHz带宽 80MHz带宽 80+80/160MHz带宽
26-tone RU 9 18 37 74
52-tone RU 4 8 16 32
106-tone RU 2 4 8 16
242-tone RU 1 2 4 8
484-tone RU 不适用(N/A) 1 2 4
996-tone RU N/A N/A 1 2
2×996-tone RU N/A N/A N/A 1
数据帧所占用的发送资源块可以具有一种类型或者多种类型的组合，也就是说，数据帧占用的发送资源块可以是RU或多RU(Multi-RU，MRU)，其中，MRU可以是两种以上RU类型的组合。
在一些示例中，可以假设带宽阈值为160MHz，也就是说，发送资源块占用的带宽大于160MHz，例如可以是320MHz或480MHz或其他情形等。
在一些实施例中，发送资源块占用的带宽为320MHz，此时，发送资源块可以为以下任一种：(a)4×996-tone RU，(b)2×996-tone+996-tone MRU(或者记为3×996-tone MRU)，(c)2×996-tone+484-tone MRU(或者记为2×996+484-tone MRU)，(d)2×996-tone+996-tone+484-tone MRU(或者记为3×996+484-tone MRU)等。
在一些实施例中，发送资源块占用的带宽为480MHz，此时，发送资源块可以为以下任一种：
(a)4×996-tone+996-tone MRU(或者记为5×996-tone MRU)，(b)4×996-tone+484-tone MRU(或者记为4×996+484-tone MRU)，(c)4×996-tone RU；(d)2×996-tone+996-tone+484-tone MRU(或者记为3×996+484-tone MRU)，(e)2×996-tone+996-tone MRU(或者记为3×996-tone MRU)，(f)2×996-tone+484-tone MRU(或者记为2×996+484-tone MRU)等。
应注意的是，上述列举仅是示意，不能解释成对本公开的实施例的限制，也可能存在未列出的其他的RU或MRU。
在一些实施例中，数据帧的物理层格式可以如图5所示。
图5示出了根据本公开的实施例的数据帧的物理层格式500的示意图。格式500包括：传统短训练字段(Legacy-Short Training Field，L-STF)501、传统长训练字段(Legacy-Long Training Field，L-LTF)502、传统信令字段(Legacy-Signal，L-SIG)503、传统信令字段重复(repeated legacy-signal，RL-SIG)504、通用信令字段(Universal SIG，U-SIG)505、极高吞吐率信令字段(Extremely High Throughput Signal Field，EHT-SIG)506、极高吞吐率短训练字段(Extremely High Throughput Short Training Field，EHT-STF)507、极高吞吐率长训练字段(Extremely High Throughput Long Training Field，EHT-LTF)508。在数据字段(Data)509后，还包括数据包分组扩展(Packet Extension，PE)510。
示例性地，L-STF 501可以用于PPDU的发现，粗同步，自动增益控制等。L-LTF 502可以用于精同步，信道估计等。L-SIG 503可以用于携带PPDU长度相关的信令信息，保证共存等。RL-SIG 504用于表示对L-SIG 503的重复。U-SIG 505是从EHT开始所采用的通用的信令字段。EHT-SIG 506可以用于携带用于解调后续数据的信令，主要包含资源单元指示信息等。EHT-STF 507可以用于后续字段的自动增益控制等。EHT-LTF 508可以用于信道估计等。Data 509可以用于承载数据信息。PE 510可以用于帮助接收设备获得更多处理时间等。
如图5所示，EHT-SIG 506可以包括公共字段(Common Field)516和用户特定字段(User Specific Field)526。
示例性地，公共字段516中可以包括RU分配子字段，该RU分配子字段可以包括RU(或MRU)类型以及对应的用户组中的用户数量。
示例性地，用户特定字段526中可以包括按照RU分配子字段中的RU分配的顺序的多个用户的标识。
在一些实施例中，数据帧的媒体接入控制(Media Access Control，MAC)层格式可以如图6所示。
图6示出了根据本公开的实施例的数据帧的MAC层格式600的示意图。格式600包括帧控制(Frame Control)601，时长(Duration)602，地址1(Address 1)603，地址2(Address 2)604，地址3(Address 3)605，序列控制(Sequence Control)606，地址4(Address 4)607，高吞吐量控制(High Throughput Control，HT Control)608，帧体(Frame Body)609以及帧校验序列(Frame Check Sequence，FCS)610。
示例性地，帧控制601可以包括多个子字段，分别用于表示协议版本、帧类型、子类型、发送方向、重传、电源管理等。举例来说，对于帧类型子字段，可以通过“10”表示帧类型为数据帧。时长602可以用于表示该数据帧与其确认帧将会占用信道的时间长度。地址1 603， 地址2 604，地址3 605和地址4 607可以统称为地址域，用于表示该数据帧的接收地址、发送地址、源地址或目的地址等。序列控制606可以用于过滤重复帧。帧体609可以用于承载具体的信息。FCS 610可以用于检错，例如FCS 610可以包括32位的循环冗余校验(Cyclic Redundancy Check，CRC)。
示例性地，如图6所示，HT控制608可以包括聚合控制(Aggregated Control，A-Control)680。该聚合控制可以包括控制列表(Control List)682以及填充(Padding)684，其中控制列表682可以包括控制标识(Control Identification，Control ID)6822、控制信息(Control Information)6824等等。
在本公开一些实施例中，发送设备201发送410数据帧时，该数据帧中可以携带TRS信息。具体地，当控制标识6822为预设值(例如为0)时，相应的控制信息6824中携带的是TRS信息。
图7示出了根据本公开的实施例的TRS信息的格式700的示意图。格式700包括上行链路数据符号(UPLink Data Symbols，UL Data Symbols)701，资源单元分配(RU Allocation)702，AP发射功率(AP TX Power)703，上行链路目标接收功率(UL Target Receive Power)704，UL调制编码集合(UL Modulation and Coding Set，UL MCS)705，以及预留(Reserved)706。
示例性地，UL数据符号701可以用于指示接收设备发送确认帧的数据部分的长度(符号数)。AP传输功率703可以用于表示AP发送功率。UL目标接收功率704可以用于表示AP所期待的上行接收功率。UL MCS 705可以用于表示接收设备发送确认帧所才用的MCS。预留706可以具有预留长度，例如1比特(bit)。
示例性地，RU分配702可以携带有RU分配信息，用于表示接收设备发送确认帧可以占用的发送信道中的频率位置，该频率位置可以是RU或MRU的形式。具体地，RU分配信息可以用于指示接收设备发送确认帧时所占用的发送信道中的RU。本公开中可以将接收设备发送确认帧时所占用的发送信道称为“响应信道”，将接收设备发送确认帧时所占用的发送信道中的RU或MRU称为“响应资源块”。
在本公开一些实施例中，RU分配702字段可以为预设长度，用于指示接收设备可以在预设带宽的信道内的RU。预设带宽可以为160MHz。可见，RU分配信息可以指示在160MHz信道中的响应资源块的位置。
RU分配信息可以包括第一指示信息和第二指示信息，其中第一指示信息具有第一长度，第二指示信息具有第二长度，第一长度与第二长度之和可以等于或小于预设长度。第一指示信息可以用于指示预设带宽信道中的哪个80MHz信道，第二指示信息可以用于指示在对应的80MHz信道中的具体RU。
在一些实现方式中，预设长度可以为8比特，第一长度可以为1比特，第二长度可以为7比特。第一指示信息可以在B0位置，第二指示信息可以在B1-B7位置。
在一些示例中，如果响应信道为主160MHz信道，那么B0为第一值表示主80MHz，B0为第二值表示从80MHz。可选地，第一值为0，第二值为1；或者可选地，第一值为1，第二值为0。在另一些示例中，如果响应信道是从160MHz信道，那么B0为第一值表示低频80MHz，B0为第二值表示高频80MHz。可选地，第一值为0，第二值为1；或者可选地，第一值为1，第二值为0。
可理解，该实现方式仅是示意性而非限制性的，本公开的实施例不排除未示出的其他实 现方式。
继续回到过程400，接收设备202可以基于发送资源块以及RU分配信息确定420响应资源块。
具体地，在确定420响应资源块时，接收设备202可以先确定响应信道，然后再确定响应信道中的响应资源块。示例性地，可以基于预设规则来确定响应信道。
在一些实现方式中，如果发送资源块的带宽小于或等于带宽阈值，那么可以确定发送资源块所在的信道为响应信道。举例来说，假设带宽阈值为160MHz，且发送资源块的带宽等于160MHz。那么如果发送资源块在主160MHz信道，那么确定响应信道也为主160MHz信道。如果发送资源块在从160MHz信道，那么确定响应信道也为从160MHz信道。
在另一些实现方式中，如果发送资源块的带宽小于或等于带宽阈值，那么可以基于预设规则确定响应信道。可选地，预设规则可以为以下至少一项：(1)主160MHz信道，(2)从160MHz信道，(3)高频160MHz信道，(4)低频160MHz信道，(5)发送资源块所在的160MHz信道，或(6)若传输方式是MU-MIMO，则与在用户组中位置所对应的160MHz信道。关于预设规则的描述可以参见下面的实现方式中的具体实施例。
在另一些实现方式中，如果发送资源块的带宽大于带宽阈值，那么可以基于预设规则确定响应信道。下面将以带宽阈值为160MHz为例进行阐述。
在一些实施例中，假设发送资源块的带宽等于320MHz，那么预设规则可以为以下至少一项：(1)主160MHz信道，(2)从160MHz信道，(3)高频160MHz信道，(4)低频160MHz信道，或(5)发送资源块所在的数据量大的160MHz信道。
可选地，可以将主160MHz信道作为响应信道；或者，可以将从160MHz信道作为响应信道；或者，可以将高频160MHz信道作为响应信道；或者，可以将低频160MHz信道作为响应信道。可理解的是，主160MHz信道可能是高频160MHz信道，也可能是低频160MHz信道；相应地，从160MHz信道可能是低频160MHz信道，也可能是高频160MHz信道。
可选地，可以将发送资源块所在的数据量大的160MHz信道作为响应信道。示例性地，当发送资源块为特定大小的MRU时，例如发送资源块为如下的MRU之一：3×996-tone MRU，2×996+484-tone MRU，或3×996+484-tone MRU，此时可以将2×996-tone RU所在的160MHz信道作为响应信道。可理解的是，2×996-tone RU所在的160MHz信道可能是高频160MHz信道，也可能是低频160MHz信道。2×996-tone RU所在的160MHz信道可能是主160MHz信道，也可能是从160MHz信道。
在另一种实施方式中，可以根据指示信息PS160以及TRS信息中的RU Allocation字段来确定回复响应帧的资源块，其中，指示信息PS160由发送资源块所在的数据量大的160MHz信道的位置以及TRS信息中的RU Allocation字段所指示的资源块大小来确定，例如，根据下表中Input中的第二列“发送资源块所在的数据量大的160MHz信道的位置”和Input中第一列“TRS信息中的RU Allocation字段所指示的资源块大小”来确定指示信息PS160。
Figure PCTCN2022089647-appb-000001
Figure PCTCN2022089647-appb-000002
例如，当TRS信息中的RU Allocation字段所指示的资源块大小为2×996+484-tone时：
若发送资源块所在的数据量大的160MHz信道为低频160MHz信道，则可以确定指示信息PS160为0；若发送资源块所在的数据量大的160MHz信道为高频160MHz信道，则可以确定PS160指示信息为1。站点在确定指示信息PS160之后，再结合TRS信息中的RU Allocation字段，就可以确定回复确认帧/块确认帧所使用的资源块的位置。再例如，当TRS信息中的RU Allocation字段所指示的资源块为小于或等于2×996-tone的RU/MRU时：若发送资源块所在的数据量大的160MHz信道为主160MHz信道，则可以确定PS160指示信息为0；若发送资源块所在的数据量大的160MHz信道为从160MHz信道，则可以确定PS160指示信息为1。需要说明的是，当TRS信息中的RU Allocation字段所指示的资源块为小于或等于2×996-tone的RU/MRU时，所述发送资源块只会位于一个160MHz信道中，因此，确定PS160指示信息的方法也可以是：若发送资源块所在的160MHz信道为主160MHz信道，则可以确定PS160指示信息为0；若发送资源块所在160MHz信道为从160MHz信道，则可以确定PS160指示信息为1。再例如，当TRS信息中的RU Allocation字段所指示的资源块为4×996-tone的RU时，无论发送资源块所在的数据量大的160MHz信道是哪个160MHz信道，PS160指示信息都为1。站点在确定指示信息PS160之后，再结合TRS信息中的RU Allocation字段，就可以确定回复确认帧/块确认帧所使用的资源块的位置。在另一些实施例中，假设发送资源块的带宽等于480MHz，那么预设规则可以为以下至少一项：(1)主160MHz信道，(2)频率较高的从160MHz信道，(3)频率较低的从160MHz信道，(4)高频160MHz信道，(5)中频160MHz信道，(6)低频160MHz信道，(7)发送资源块所在的数据量大的160MHz信道。
可理解，对于480MHz，可以将其分为3个160MHz信道。在一例中，3个160MHz信道可以包括1个主160MHz信道以及2个从160MHz信道，其中，2个从160MHz信道中之一频率较高，另一频率较低。在另一例中，3个160MHz信道可以包括高频160MHz信道，中频160MHz信道，和低频160MHz信道。可选地，可以将上述任一160MHz信道作为响应信道。
可选地，可以将发送资源块所在的数据量大的160MHz信道作为响应信道。示例性地，当发送资源块为特定大小的MRU时，类似地可以将2×996-tone RU所在的160MHz信道作为响应信道。可理解的是，2×996-tone RU所在的160MHz信道可能是高频160MHz信道，也可能是中频160MHz信道，也可能是低频160MHz信道。
如此，在该实现方式中，可以预先设定预设规则，从而便于接收设备确定响应信道。可理解，不同的接收设备可以使用不同的预设规则，举例来说，一个接收设备可以将主160MHz信道作为响应信道，而另一接收设备可以将从160MHz信道作为响应信道。可见，该实现方式对于SU-MIMO传输来说，能够使总带宽的各个信道都能被充分地利用，实现了资源优化利用，且保证了确认帧的传输效率。
在另一实现方式中，对于MU-MIMO传输来说，接收设备202基于预设规则确定响应信道，可以包括：基于数据帧的EHT-SIG字段，确定数据帧的传输方式是MU-MIMO；基于EHT-SIG字段中的接收设备202的标识(Identifier，ID)，确定接收设备202在MU-MIMO的用户组中的位置；基于该位置确定响应信道。
具体地，如图5所示，数据帧的物理层格式包括EHT-SIG 506，可以基于EHT-SIG 506中的公共字段516确定数据帧的传输方式。示例性地，公共字段516中的RU分配子字段还可以进一步指示用户组中用户的数量。在一些示例中，MU的数量可以小于或等于空间流的数量，空间流的数量可以表示MU的数量可以达到的最大值。
示例性地，数据帧的物理层格式包括EHT-SIG 506，可以基于EHT-SIG 506中的公共字段516和用户特定字段526确定位置。
用户特定字段526中用户出现的顺序与对应的RU分配子字段中划分出的RU顺序相一致，用户可以通过读取用户特定字段526中的接收设备ID来识别出该用户特定字段526是否属于自己，结合用户字段出现的位置与对应的资源单元分配子字段，用户可以知晓自己的RU分配情况。
举例来讲，假设公共字段516中指示多个不同的tone RU。作为一例，可以假设包括2×996+484-tone MRU和484-tone RU，并且2×996+484-tone MRU对应的用户组中用户的数量为8，484-tone RU对应的用户组中用户的数量也为8。可选地，可以将同一RU(或MRU)对应的多接收设备属于同一个MU-MIMO组，例如2×996+484-tone MRU对应的用户组(8个)是第一MU-MIMO组，484-tone RU对应的用户组(8个)是第二MU-MIMO组。在本公开的实施例中，接收设备202在MU-MIMO的用户组中的位置可以是指，该接收设备202在其所在的MU-MIMO组中的位置。
接收设备202可以基于用户特定字段526确定在所有顺序(16个)中的第一位置。在一例中，假设在所有顺序中的第一位置小于或等于8，例如第5位，那么该接收设备202对应的RU分配情况是2×996+484-tone MRU，并且其在所属的MU-MIMO的用户组(即第一MU-MIMO组)中的位置是5。假设在所有顺序中的第一位置大于8，例如第12位，那么该接收设备202对应的RU分配情况是484-tone RU，并且其在所属的MU-MIMO的用户组(即第二MU-MIMO组)中的位置是12-8＝4。
示例性地，如果该位置为预定位置，则可以确定响应信道为第一160MHz信道；相反，如果位置为非预定位置，则确定响应信道为第二160MHz信道。
在接收设备202在MU-MIMO组中的位置是预定位置的情况下，那么可以确定响应信道为第一160MHz信道。
在一些实施例中，假设发送资源块的带宽等于320MHz。可选地，第一160MHz信道可以为主160MHz信道或从160MHz信道。或者，可选地，第一160MHz信道可以为高频160MHz信道或低频160MHz信道。
在一些实施例中，假设发送资源块的带宽等于480MHz。可选地，第一160MHz信道可 以为主160MHz信道或频率较高的从160MHz信道或频率较低的从160MHz信道。或者，可选地，第一160MHz信道可以为高频160MHz信道或中频160MHz信道或低频160MHz信道。
在接收设备202在MU-MIMO组中的位置不是预定位置(即非预定位置)的情况下，可以确定响应信道为第二160MHz信道，且第二160MHz信道不同于第一160MHz信道。
示例性地，在本公开的实施例中的预定位置可以是以下至少一项：奇数位置，偶数位置，前一半位置，或后一半位置。
示例性地，MU-MIMO组的MU数量假设为N，并且假设接收设备202的位置是N个中的第P位。那么，如果P mod 2等于0(mod表示余数)，即P是偶数，那么接收设备202位于偶数位置；否则位于奇数位置。
在一些示例中，如果
Figure PCTCN2022089647-appb-000003
(
Figure PCTCN2022089647-appb-000004
表示下取整)，那么接收设备202位于前一半位置；否则位于后一半位置。在这样的示例中，如果MU-MIMO组的MU数量(N)为奇数，那么位于中间的接收设备属于后一半位置。在另一些示例中，如果
Figure PCTCN2022089647-appb-000005
(
Figure PCTCN2022089647-appb-000006
表示上取整)，那么接收设备202位于前一半位置；否则位于后一半位置。在这样的示例中，如果MU-MIMO组的MU数量(N)为奇数，那么位于中间的接收设备属于前一半位置。
举例来讲，假设MU-MIMO组的MU数量为8，接收设备202位于第5位，那么其处于奇数位置，处于后一半位置。举例来讲，假设MU-MIMO组的MU数量为8，接收设备202位于第2位，那么其处于偶数位置，处于前一半位置。
如此，在本实现方式中，可以预先设定预设规则，从而便于接收设备确定响应信道。并且，属于同一个MU-MIMO组的不同的接收设备可以确定不同的响应信道。举例来说，奇数位置的接收设备(第1个，第3个，第5个…(如果存在的话))可以将主160MHz信道作为响应信道，而偶数位置的接收设备(第2个，第4个，第6个…(如果存在的话))可以将从160MHz信道作为响应信道。可见，该实现方式对于MU-MIMO传输来说，能够使总带宽的各个信道都能被充分地利用，实现了资源优化利用，且保证了确认帧的传输效率。
可理解，在确定420响应信道之后，接收设备202可以基于RU分配信息来确定响应资源块。示例性地，可以基于RU分配信息中的B0位确定是响应信道中的哪个80MHz信道，进一步地基于RU分配信息中的B1-B7位确定该80MHz信道中具体RU。
然后，接收设备202可以在响应资源块上向发送设备201发送430针对数据帧的确认帧。
以此方式，在数据帧的发送资源块大于带宽阈值的情况下，接收设备能够基于预设规则确定响应信道，从而能够准确地基于RU分配信息确定响应资源块，该方案更加完善，不会出现接收设备不知道在哪个信道发送确认帧的情形，并且根据本公开的实施例的方案不需要使用额外比特进行指示，避免对数据帧的格式进行针对性的修改，适用性强。
图8示出了根据本公开的实施例的信息传输方法800的一个示意流程图。作为示例，方法800可以实现在图2所示的接收设备202处。为了便于理解，以下以接收设备202为例对信息传输方法800进行描述，但这仅仅是示例性的，无意对本公开的实施例进行任何限制。
方法800开始于框810。在810处，接收设备202接收来自发送设备的数据帧。该数据帧占用发送资源块，并且数据帧包括RU分配信息。
在一些实施例中，发送资源块可以是4×996-tone RU、3×996-tone MRU、2×996+484-tone MRU、3×996+484-tone MRU等。应当理解，上述关于发送资源块的示例仅仅是说明性而非限制性的，在根据本公开的实施例中也可以使用其他适当的RU或MRU来作为发送资源块。
示例性地，关于来自发送设备的数据帧的相关描述，可以上面结合410所描述的具体实 施例，为了简洁，这里不再赘述。
在820处，接收设备202基于发送资源块以及RU分配信息，确定响应资源块。
在一些实施例中，当发送资源块的带宽大于带宽阈值(如320MHz等)时，可以基于预设规则确定响应信道，然后再基于响应信道和RU分配信息确定响应资源块。在本公开的实施例中，响应信道可以是响应160MHz信道。
可选地，响应信道可以包括以下至少一项：主160MHz信道，从160MHz信道，高频160MHz信道，低频160MHz信道，或发送资源块所在的数据量大的160MHz信道。
可选地，可以基于数据帧的EHT-SIG字段，确定数据帧的传输方式是MU-MIMO；基于EHT-SIG字段中的接收设备202的标识，确定接收设备202在MU-MIMO的用户组中的位置；基于位置确定响应信道。
示例性地，接收设备202在MU-MIMO的用户组中的位置可以是接收设备2在MU-MIMO组中的位置。如果该位置为预定位置，则确定响应信道为第一160MHz信道；如果该位置不是预设位置(即非预设位置)，则确定响应信道为第二160MHz信道。可选地，第一160MHz信道不同于第二160MHz信道。
可选地，第一160MHz信道可以为主160MHz信道或从160MHz信道。可选地，第一160MHz信道可以为高频160MHz信道或低频160MHz信道。
在一些示例中，第一160MHz信道为主160MHz信道，第二160MHz信道为从160MHz信道。在另一些示例中，第一160MHz信道为高频160MHz信道，第二160MHz信道为低频160MHz信道。
可理解，关于框820的具体实现方式可以参照过程400中接收设备202如何确定420响应资源块的详细描述。为了简洁，这里不再重复。
在830处，接收设备202在响应资源块上向发送设备201发送针对数据帧的确认帧。
如此，接收设备能够基于预设规则确定响应信道，进而能够正确地发送确认帧，确保了信息传输的效率。在本公开的一些实施例中，接收设备在830处可以发送块确认帧，此处不再赘述。
图9示出了根据本公开的实施例的信息传输方法900的一个示意流程图。作为示例，方法900可以实现在图2所示的发送设备201处。为了便于理解，以下以发送设备201为例对信息传输方法900进行描述，但这仅仅是示例性的，无意对本公开的实施例进行任何限制。
在910处，发送设备201向接收设备发送数据帧，其中数据帧占用发送资源块以及数据帧包括RU分配信息。
在本公开的实施例中，发送资源块可以为以下任一种：4×996-tone RU，3×996-tone MRU，2×996+484-tone MRU，3×996+484-tone MRU等。
示例性地，关于来自发送设备的数据帧的相关描述，可以上面结合410所描述的具体实施例，为了简洁，这里不再重复。
在920处，发送设备201基于发送资源块以及RU分配信息，确定响应资源块。
在一些实施例中，当发送资源块的带宽大于带宽阈值(如320MHz等)时，可以基于预设规则确定响应信道，然后再基于响应信道和RU分配信息确定响应资源块。在本公开的实施例中，响应信道可以是响应160MHz信道。
可选地，响应信道可以包括以下至少一项：主160MHz信道，从160MHz信道，高频160MHz信道，低频160MHz信道，或发送资源块所在的数据量大的160MHz信道。
可选地，可以基于数据帧的EHT-SIG字段，确定数据帧的传输方式是MU-MIMO；基于EHT-SIG字段中的接收设备的标识，确定接收设备在MU-MIMO的用户组中的位置；基于位置确定响应信道。
示例性地，接收设备在MU-MIMO的用户组中的位置可以是接收设备在MU-MIMO组中的位置。如果该位置为预定位置，则确定响应信道为第一160MHz信道；如果该位置不是预设位置(即非预设位置)，则确定响应信道为第二160MHz信道。可选地，第一160MHz信道不同于第二160MHz信道。
可选地，第一160MHz信道可以为主160MHz信道或从160MHz信道。可选地，第一160MHz信道可以为高频160MHz信道或低频160MHz信道。
在一些示例中，第一160MHz信道为主160MHz信道，第二160MHz信道为从160MHz信道。在另一些示例中，第一160MHz信道为高频160MHz信道，第二160MHz信道为低频160MHz信道。
可理解，关于920的具体实现方式可以类似地参照上面结合420的详细描述，也就是说，发送设备201和接收设备202可以采用类似的方式来确定响应信道，进一步确定响应资源块。这样能够确保接收端和发送端的一致性。为了简洁，这里不再重复。
在930处，发送设备201在响应资源块上接收来自接收设备202针对数据帧的确认帧。
如此，发送设备能够基于预设规则确定响应信道，进而能够正确地接收确认帧，确保了信息传输的效率。在本公开的一些实施例中，发送设备在930处可以接收块确认帧，此处不再赘述。

图10示出了根据本公开的实施例的通信装置1000的另一个示意框图。装置1000可以被实现在接收设备202处，或者可以被实现为接收设备202中的芯片或芯片系统，本公开的范围在此方面不限制。
