Communication method, electronic device and storage medium

Technical Field

本公开实施例涉及移动通信技术领域，具体而言，本公开实施例涉及一种通信方法、电子设备及存储介质。The embodiments of the present disclosure relate to the field of mobile communication technology. Specifically, the embodiments of the present disclosure relate to a communication method, an electronic device, and a storage medium.

Background Art

点对点(Peer to Peer，P2P)的通信方式进行数据传输无需通过接入点，避免了网络拥塞引起的延迟，可进一步提高传输效率。由于部分站点接收能力受限，还提出了应用于non AP MLD的增强型多链路单无线电(Enhanced Multi Link Single Radio，EMLSR)模式。然而，在EMLSR模式下，还需要完善传输共享时隙内站点设备间的P2P通信。The peer-to-peer (P2P) communication mode does not require data transmission through an access point, avoiding delays caused by network congestion and further improving transmission efficiency. Due to the limited receiving capabilities of some sites, an Enhanced Multi Link Single Radio (EMLSR) mode for non-AP MLD is also proposed. However, in the EMLSR mode, it is also necessary to improve the P2P communication between site devices in the transmission shared time slot.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

本公开实施例提供了一种通信方法、电子设备及存储介质，用以提供一种P2P通信方式。 The embodiments of the present disclosure provide a communication method, an electronic device, and a storage medium, which are used to provide a P2P communication mode.

其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

作为第一示例，参见图1，对本公开各实施例提供通信方法的示例进行说明。As a first example, referring to FIG. 1 , an example of a communication method provided by various embodiments of the present disclosure is described.

如图1所示，AP1(Access Point，接入点设备)附属于AP MLD1；AP1可作为TXOP持有者，向与其关联的STA分配TXOP时隙。STA1附属于non-AP MLD1(STA1可作为本公开实施例的第一STA)；STA1为与所述AP关联的站点。STA2附属于non-AP MLD2(STA2可作为本公开实施例的第二STA)，且STA2处于EMLSR工作模式；STA2为与STA1之间建立TDLS链路。AP1、STA1、STA2在同一个基本服务集(Basic Service Sets Basic Service Set，BSS)。As shown in Figure 1, AP1 (Access Point, access point device) is attached to AP MLD1; AP1 can act as a TXOP holder and allocate TXOP time slots to STAs associated with it. STA1 is attached to non-AP MLD1 (STA1 can be the first STA in the embodiment of the present disclosure); STA1 is a station associated with the AP. STA2 is attached to non-AP MLD2 (STA2 can be the second STA in the embodiment of the present disclosure), and STA2 is in EMLSR working mode; STA2 establishes a TDLS link with STA1. AP1, STA1, and STA2 are in the same Basic Service Set (BSS).

其中，如图1所示，AP1分别向STA1、STA2发送第一无线帧，第一无线帧可以为MU-RTS TXS Trigger帧。As shown in Figure 1, AP1 sends the first wireless frame to STA1 and STA2 respectively, and the first wireless frame can be a MU-RTS TXS Trigger frame.

所述第一无线帧中携带第一标识信息，所述第一标识信息指示：所述第一无线帧对站点设备STA的触发类型；所述触发类型包括：第一触发类型或第二触发类型；所述第一触发类型包括触发第一STA在所述AP1分配的时隙内向所述AP1或者所在基本服务集内的其他STA发送数据；所述第二触发类型包括触发工作在EMLSR模式链路的第二STA由监听工作模式切换为收发操作工作模式。The first wireless frame carries first identification information, and the first identification information indicates: the trigger type of the first wireless frame for the site device STA; the trigger type includes: the first trigger type or the second trigger type; the first trigger type includes triggering the first STA to send data to the AP1 or other STAs in the basic service set within the time slot allocated by the AP1; the second trigger type includes triggering the second STA working in the EMLSR mode link to switch from the listening working mode to the transceiver operation working mode.

此外，所述触发类型为所述第二触发类型时，所述AP1在唤醒处于EMLSR的第二STA时，还为其分配用于P2P通信的时隙。In addition, when the trigger type is the second trigger type, the AP1 also allocates a time slot for P2P communication to the second STA when waking up the second STA in the EMLSR.

也就是说，所述第一无线帧触发第二触发类型时，一方面触发工作在EMLSR模式链路的第二STA由监听工作模式切换为收发操作工作模式，另一方面，所述AP1在唤醒处于EMLSR的第二STA时，还为其分配用于P2P通信的时隙，以便于第二STA与第一STA在共享传输机会内进行P2P通信。That is to say, when the first wireless frame triggers the second trigger type, on the one hand, it triggers the second STA working in the EMLSR mode link to switch from the listening working mode to the transceiver operation mode; on the other hand, when the AP1 wakes up the second STA in the EMLSR, it also allocates a time slot for P2P communication to it, so that the second STA and the first STA can perform P2P communication in the shared transmission opportunity.

可选的，所述第一标识信息携带于所述第一无线帧的用户信息字段中。例如，所述用户信息字段可以为被调度站点用户信息(User Info)字段，或与被调度站点建立TDLS链路且处于EMLSR操作模式站点用户信息字段。Optionally, the first identification information is carried in a user information field of the first wireless frame. For example, the user information field may be a user information (User Info) field of the scheduled site, or a user information field of a site that establishes a TDLS link with the scheduled site and is in the EMLSR operation mode.

可选的，所述用户信息字段可以为MU-RTS TXS Trigger帧的EHT variant User Info字段。作为示例，EHT variant User Info字段的格式可以如表1所示：Optionally, the user information field may be an EHT variant User Info field of a MU-RTS TXS Trigger frame. As an example, the format of the EHT variant User Info field may be as shown in Table 1:

表1：
Table 1:

具体而言，AP1向所述STA1、STA2发送MU-RTS TXS Trigger帧后，STA1、STA2可根据用户信息字段中的AID12字段进行匹配，确定其对应的触发类型。例如，以STA1为例，MU-RTS TXS Trigger帧中，AID12字段标识的信息与对应STA1对应，那么，用户信息字段中对应的第一标识信息标识的触发类型即为对STA1的触发类型。Specifically, after AP1 sends the MU-RTS TXS Trigger frame to STA1 and STA2, STA1 and STA2 can match the AID12 field in the user information field to determine the corresponding trigger type. For example, taking STA1 as an example, in the MU-RTS TXS Trigger frame, the information identified by the AID12 field corresponds to the corresponding STA1, then the trigger type identified by the corresponding first identification information in the user information field is the trigger type for STA1.

可选的，在MU-RTS TXS Trigger帧中，可通过将所述第一标识信息设置为第一参数值来指示所述触发类型为所述第一触发类型；这种情况下，所述用户信息字段对应的站点设备(即STA1)为被调度站点设备；AP1为STA1分配传输机会。Optionally, in the MU-RTS TXS Trigger frame, the trigger type can be indicated as the first trigger type by setting the first identification information to a first parameter value; in this case, the site device corresponding to the user information field (i.e., STA1) is the scheduled site device; and AP1 allocates a transmission opportunity to STA1.

作为示例，所述第一参数值可以为1。As an example, the first parameter value may be 1.

可选的，在MU-RTS TXS Trigger帧中，可通过将所述第一标识信息设置为第二参数值来指示触发类型为所述第二触发类型；这种情况下，所述用户信息字段对应的站点设备(即STA2)在接收到所述MU-RTS TXS Trigger帧后，由监听工作模式切换为收发操作工作模式。Optionally, in the MU-RTS TXS Trigger frame, the first identification information can be set to a second parameter value to indicate that the trigger type is the second trigger type; in this case, the site device corresponding to the user information field (i.e., STA2) switches from the listening working mode to the transceiver operation mode after receiving the MU-RTS TXS Trigger frame.

作为示例，所述第二参数值可以为0。As an example, the second parameter value may be 0.

此外，第一标识位设置为第二参数值，所述用户信息字段中还可包含第一子字段，所述第一子字段标识所述AP分配的传输机会内可用于P2P 传输时隙。In addition, the first identification bit is set to the second parameter value, and the user information field may also include a first subfield, wherein the first subfield identifies the transmission opportunity allocated by the AP that can be used for P2P Transmission time slot.

可选的，所述第一子字段可携带于MU-RTS TXS Trigger帧的EHT variant User Info字段中。Optionally, the first subfield may be carried in the EHT variant User Info field of the MU-RTS TXS Trigger frame.

作为示例，EHT variant User Info字段的格式可以如表2所示：As an example, the format of the EHT variant User Info field may be as shown in Table 2:

表2：
Table 2:

接收到MU-RTS TXS Trigger帧后，STA1、STA2可根据用户信息字段中的AID12字段进行响应。After receiving the MU-RTS TXS Trigger frame, STA1 and STA2 can respond according to the AID12 field in the user information field.

其中，STA1根据所述MU-RTS TXS Trigger帧中的RU Allocation字段所标识的资源，向所述AP1回复准许发送CTS帧。这样，STA1可在所述用户信息字段携带的Allocation Duration子字段标识的时隙内，向AP1或者所在基本服务集内的其他STA传输数据。其中，其他STA为与第一STA建立TDLS链路的站点。其他STA例如STA2。Among them, STA1 replies to the AP1 with permission to send a CTS frame according to the resources identified by the RU Allocation field in the MU-RTS TXS Trigger frame. In this way, STA1 can transmit data to AP1 or other STAs in the basic service set in the time slot identified by the Allocation Duration subfield carried by the user information field. Among them, other STAs are stations that establish a TDLS link with the first STA. Other STAs are, for example, STA2.

STA2接收到MU-RTS TXS Trigger帧后，可根据MU-RTS TXS Trigger帧中，用户信息字段中的RU Allocation字段分配的资源，向AP回复CTS帧。并且，STA2由监听工作模式切换为收发操作工作模式，其在第一子字段(Duration for P2P)规定的时隙内，保持收发状态，具备接收或者传输数据的能力。例如，处于收发操作工作模式的STA2可接收STA1发送的RTS帧，并向STA1反馈CTS帧后，STA2可与STA1传输P2P数据。After STA2 receives the MU-RTS TXS Trigger frame, it can reply a CTS frame to the AP based on the resources allocated by the RU Allocation field in the user information field in the MU-RTS TXS Trigger frame. In addition, STA2 switches from the listening mode to the transceiver mode, and maintains the transceiver state within the time slot specified by the first subfield (Duration for P2P), and has the ability to receive or transmit data. For example, STA2 in the transceiver mode can receive the RTS frame sent by STA1, and after feeding back the CTS frame to STA1, STA2 can transmit P2P data with STA1.

本公开实施例中，AP确定并向STA发送第一无线帧，所述第一无线帧中携带第一标识信息可指示第一触发类型或第二触发类型，由此实现了在TXOP共享机制内，AP向其目标站点(第一STA)分配传输机会的同时，唤醒处于EMLSR的站点设备(第二STA)，使该处于EMLSR的站点设备由监听工作模式切换为收发操作工作模式，实现了EMLSR链路下共享传输机制内的P2P通信，提高信道竞争的效率和P2P传输效率及可靠性。In the embodiment of the present disclosure, the AP determines and sends a first wireless frame to the STA, and the first identification information carried in the first wireless frame can indicate the first trigger type or the second trigger type, thereby realizing that within the TXOP sharing mechanism, the AP allocates a transmission opportunity to its target station (the first STA) and wakes up the station device (the second STA) in the EMLSR, so that the station device in the EMLSR switches from the listening working mode to the transceiver operation working mode, and realizes the EMLSR link down P2P communication within the shared transmission mechanism improves the efficiency of channel contention and the efficiency and reliability of P2P transmission.

参见图2，本公开实施例提供了一种通信方法，可选地，该方法可应用于接入点(Access Point，AP)设备；可选地，本公开实施例中，AP例如具有无线至有线桥接(Bridging)功能的设备，AP负责将有线网络所提供的服务延伸至无线网络；站点设备例如具有无线网络接入功能的电子设备，提供帧传递(Frame Delivery)服务让信息得以传递。可选地，在本公开实施例中，STA可以为支持多连接的设备，例如，可以表示为non-AP MLD。Referring to FIG. 2 , an embodiment of the present disclosure provides a communication method, which can be applied to an access point (AP) device. Optionally, in the embodiment of the present disclosure, the AP is, for example, a device with a wireless to wired bridging function, and the AP is responsible for extending the services provided by the wired network to the wireless network. The station device is, for example, an electronic device with a wireless network access function, and provides a frame delivery service to enable information to be transmitted. Optionally, in the embodiment of the present disclosure, the STA can be a device that supports multiple connections, for example, it can be represented as a non-AP MLD.

该方法可以包括以下步骤：The method may include the following steps:

步骤201，确定第一无线帧。Step 201: determine a first radio frame.

步骤202，发送所述第一无线帧。Step 202: Send the first wireless frame.

在WLAN中，引入了传输机会(Transmit Opportunity，TXOP)，当接入点设备(AP)作为一个TXOP持有者(Holder)，发送触发帧分配持有的TXOP的一部分时间给其关联的站点设备STA，该STA在被分配的时隙内可以向所述AP发送上行数据或者与其他的站点进行点到点(Point to Point,P2P)传输。In WLAN, Transmit Opportunity (TXOP) is introduced. When an access point device (AP) acts as a TXOP holder, it sends a trigger frame to allocate a part of the TXOP time held to its associated station device STA. The STA can send uplink data to the AP or perform point-to-point (P2P) transmission with other stations within the allocated time slot.

P2P传输是指两个non-AP站点通过通道直接链路建立(Tunneled Direct Link Setup，TDLS)的P2P链路进行数据传输，无需通过接入点，避免了网络拥塞引起的延迟，可有效提高传输效率。其中，多链路设备(Multi-Link Device，MLD)同样支持TDLS功能，在某个基本服务集(Basic Service Set,BSS)内，non-AP MLD可通过TDLS发现、建立和确认等流程发现支持TDLS功能的站点并协商建立P2P链路。P2P transmission refers to the transmission of data between two non-AP stations through a P2P link established by a tunneled direct link setup (TDLS), without going through an access point, thus avoiding delays caused by network congestion and effectively improving transmission efficiency. Among them, multi-link devices (MLD) also support TDLS functions. In a BSS, non-AP MLD can discover sites that support TDLS functions and negotiate to establish P2P links through TDLS discovery, establishment, and confirmation processes.

此外，在极高吞吐量(extreme high-throughput，EHT)通信中，还引入了增强型多链路单无线通信(enhanced–multilink single radio，EMLSR)模式。non-AP MLD可以在增强型多链路单无线通信(enhanced–multilink single radio，EMLSR)模式下与支持EMLSR模式的AP MLD进行通信。其中，EMLSR模式是指non-AP MLD在某一时刻只能在一个链路下与AP MLD通信，但可以在多个链路下进行信道的监听。也就是说，当non-AP MLD处于EMLSR模式时，可对信道进行监听操作，以及接收AP MLD发送的初始控制帧。In addition, the enhanced–multilink single radio (EMLSR) mode is introduced in extreme high-throughput (EHT) communication. Non-AP MLD can communicate with AP MLD supporting EMLSR mode in enhanced–multilink single radio (EMLSR) mode. EMLSR mode means that non-AP MLD can only communicate with AP MLD under one link at a time, but can monitor channels under multiple links. In other words, when non-AP MLD is in EMLSR mode, it can monitor the channel and receive the initial control frame sent by AP MLD.

本公开实施例中，提出一种EMLSR模式下的P2P通信方式，AP确定并发送第一无线帧，用于在TXOP共享机制内，向第一STA分配传输机会，并唤醒处于EMLSR模式的第二STA，使所述第二STA由监听工作模式切换为收发操作工作模式，以便于在共享传输机会内进行P2P通信。In an embodiment of the present disclosure, a P2P communication method in EMLSR mode is proposed, where the AP determines and sends a first wireless frame, which is used to allocate a transmission opportunity to a first STA within a TXOP sharing mechanism, and wake up a second STA in EMLSR mode, so that the second STA switches from a listening working mode to a transceiver operating mode, so as to facilitate P2P communication within a shared transmission opportunity.

可选的，所述第一无线帧可以包括多用户发送请求传输机会共享(Multi-User Request To Send TXOP Sharing,MU-RTS TXS)触发帧。Optionally, the first wireless frame may include a multi-user request to send TXOP sharing (MU-RTS TXS) trigger frame.

其中，所述第一STA包括与所述AP关联的站点。所述第二STA包括与所述第一STA建立TDLS的站点，且第二STA工作于EMLSR操作模式；所述第二STA为附属于non-AP MLD的一个或多个non-AP STA。The first STA includes a station associated with the AP. The second STA includes a station that establishes TDLS with the first STA, and the second STA works in EMLSR operation mode; the second STA is one or more non-AP STAs attached to the non-AP MLD.

所述第一无线帧中携带第一标识信息，所述第一标识信息指示：所述第一无线帧对STA的触发类型；所述触发类型包括：第一触发类型或第二触发类型。其中，所述第一触发类型包括触发第一STA在所述AP分配的时隙内向所述AP或者所在基本服务集内的其他STA发送数据；所述第二触发类型包括触发工作在EMLSR模式链路的第二STA由监听工作模式切换为收发操作工作模式。The first radio frame carries first identification information, and the first identification information indicates: the trigger type of the first radio frame for the STA; the trigger type includes: the first trigger type or the second trigger type. The first trigger type includes triggering the first STA to send data to the AP or other STAs in the basic service set in the time slot allocated by the AP; the second trigger type includes triggering the second STA working in the EMLSR mode link to switch from the listening working mode to the transceiver operation working mode.

本公开实施例中，AP确定并向STA发送第一无线帧，所述第一无线帧中携带第一标识信息可指示第一触发类型或第二触发类型，由此实现了在TXOP共享机制内，AP向其目标站点(第一STA)分配传输机会的同时，唤醒处于EMLSR的站点设备(第二STA)，使该处于EMLSR的站点设备由监听工作模式切换为收发操作工作模式，实现了EMLSR链路下共享传输机制内的P2P通信，提高信道竞争的效率和P2P传输效率及可靠性。In the embodiment of the present disclosure, the AP determines and sends a first wireless frame to the STA, and the first identification information carried in the first wireless frame can indicate the first trigger type or the second trigger type, thereby realizing that within the TXOP sharing mechanism, the AP allocates a transmission opportunity to its target station (the first STA) at the same time. When waking up, the site device (second STA) in EMLSR is switched from the listening mode to the transceiver mode, thereby realizing P2P communication within the shared transmission mechanism under the EMLSR link and improving the efficiency of channel competition and P2P transmission efficiency and reliability.
