本发明涉及通信技术领域，尤其涉及一种多链路操作方法、装置、设备及存储介质。The present invention relates to the technical field of communication, and in particular to a multi-link operation method, device, equipment and storage medium.
背景技术Background technique
在802.11系统中，接入点设备(AP STA)和终端设备(Non-AP STA)在内部都部署有MAC层和PHY层，其中MAC层的主要功能有信道管理、连接管理、服务质量管理、功率控制和时间同步等，PHY层的主要功能有调制、编码和传输等。In the 802.11 system, both the access point device (AP STA) and the terminal device (Non-AP STA) are equipped with a MAC layer and a PHY layer internally. The main functions of the MAC layer include channel management, connection management, service quality management, Power control and time synchronization, etc., the main functions of the PHY layer are modulation, coding and transmission.
MAC层和PHY层在概念上都包括分别称为MAC层管理实体MLME(MAC sublayermanagement entity)和物理层管理实体PLME(PHY sublayer management entity)的管理实体。这些单元提供了低层管理服务接口，通过这些接口可以调用低层管理功能。Conceptually, both the MAC layer and the PHY layer include management entities called MAC layer management entity MLME (MAC sublayer management entity) and physical layer management entity PLME (PHY sublayer management entity). These units provide low-level management service interfaces through which low-level management functions can be invoked.
为了提供正确的MAC操作，每个STA(包括Non-AP STA和AP STA)中都有一个高层管理实体，如SME(station management entity，设备管理实体)，SME表示在MAC层之上的高层管理实体，是一个独立于层的单元，它位于单独的管理平面中。In order to provide correct MAC operation, each STA (including Non-AP STA and AP STA) has a high-level management entity, such as SME (station management entity, equipment management entity), SME represents the high-level management above the MAC layer Entity, which is a layer-independent unit, resides in a separate management plane.
SME的作用：通常，该单元负责诸如从各种层管理实体(MLME和PLME)收集与层相关的状态之类的功能，类似地，其还会设置特定于层的参数值。SME通常代表一般的系统管理实体执行此类功能。图1描述了管理实体之间的关系。Role of the SME: Typically, this unit is responsible for functions such as collecting layer-related status from the various layer management entities (MLME and PLME), and similarly it also sets layer-specific parameter values. SMEs typically perform such functions on behalf of general system management entities. Figure 1 describes the relationship between managed entities.
802.11网络，也就是无线局域网络(WLAN)，通过一系列系统特性和多种机制增强功能以实现高无线局域网吞吐量。随着无线局域网(WLAN)的使用持续增长，对于在许多环境(例如家庭，企业和热点)中提供无线数据服务越来越重要。特别是，视频流量将继续是许多WLAN部署中的主要流量类型。由于出现了4k和8k视频(20Gbps的未压缩速率)，这些应用的吞吐量要求正在不断发展。诸如虚拟现实或增强现实、游戏、远程办公室和云计算之类的新型高吞吐量，低延迟应用程序将会激增(例如，实时游戏的延迟低于5毫秒)。802.11 networks, also known as wireless local area networks (WLANs), enhance functionality through a series of system features and mechanisms to achieve high WLAN throughput. As the use of wireless local area networks (WLANs) continues to grow, it is increasingly important to provide wireless data services in many environments such as homes, businesses and hotspots. In particular, video traffic will continue to be the dominant traffic type in many WLAN deployments. Throughput requirements for these applications are evolving due to the advent of 4k and 8k video (20Gbps uncompressed). New high-throughput, low-latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., real-time gaming with sub-5ms latency).
鉴于这些应用程序的高吞吐量和严格的实时延迟要求，用户期望通过WLAN支持其应用程序时，吞吐量更高，可靠性更高，延迟更少，电源效率更高。802.11be系统旨在通过进一步提高总吞吐量和降低延迟来确保WLAN的竞争力，同时确保与旧版技术标准向后兼容和共存。Given the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency, and greater power efficiency when supporting their applications over WLAN. The 802.11be system is designed to ensure the competitiveness of WLANs by further increasing overall throughput and reducing latency, while ensuring backward compatibility and coexistence with older technical standards.

AP MLD可根据负载、数据量等因素向STA MLD发送第一消息，也可根据STA MLD的请求向STA MLD发送第一消息，指示STA MLD启用增强的多链路操作方式，或者指示STA MLD使用哪种操作模式，如使用第一模式，则STA MLD在相同时段只监听一条链路，只在一条链路上接收或发送控制消息和数据；如使用第二模式，则STA MLD相同时段监听两条链路，可以在两条链路上接收控制消息，但只在一条链路上接收和发送业务数据。The AP MLD can send the first message to the STA MLD according to factors such as load and data volume, and can also send the first message to the STA MLD according to the request of the STA MLD, instructing the STA MLD to enable the enhanced multi-link operation mode, or instruct the STA MLD to use Which mode of operation, if the first mode is used, the STA MLD only monitors one link at the same time period, and only receives or sends control messages and data on one link; if the second mode is used, the STA MLD monitors two links at the same time period It can receive control messages on two links, but only receive and send service data on one link.
S1002、STA MLD和AP MLD根据所述多链路操作模式进行数据传输。S1002, the STA MLD and the AP MLD perform data transmission according to the multi-link operation mode.
STA MLD和AP MLD可在出厂前配置好增强的多链路操作方式的实施方式，即APMLD指示启用增强的多链路操作方式，STA MLD和AP MLD根据之前的配置执行相应操作，也可将增强的多链路操作方式划分为不同的操作模式，不同的操作模式对应不同的操作。STA MLD and AP MLD can configure the enhanced multi-link operation mode before leaving the factory, that is, APMLD indicates to enable the enhanced multi-link operation mode, and STA MLD and AP MLD perform corresponding operations according to the previous configuration, or set The enhanced multi-link operation mode is divided into different operation modes, and different operation modes correspond to different operations.

或者，or,
AP MLD同时监听链路link1和link2，如果监听到link1空闲，则在link1上发送控制消息给STA MLD，如果监听到link1不空闲，而link2空闲，则在link2上发送控制消息给STA MLD；STA MLD接收到控制消息后，在接收到控制消息的链路上发送响应消息给AP MLD；AP MLD在接收到响应消息后，在接收响应消息的链路上发送数据给STA MLD。AP MLD monitors link1 and link2 at the same time. If it detects that link1 is idle, it sends a control message to STA MLD on link1. If it detects that link1 is not idle but link2 is idle, it sends a control message to STA MLD on link2; STA After receiving the control message, the MLD sends a response message to the AP MLD on the link receiving the control message; after receiving the response message, the AP MLD sends data to the STA MLD on the link receiving the response message.

如果第一消息中包含的多链路操作模式指示使用第二模式，则STA MLD同时监听链路link1和link2，如果在link1上接收到控制消息，则在link1上发送响应消息给AP1，并在link1上发送数据给AP MLD；如果在link2上接收到控制消息，则在link2上发送响应消息给AP2，并在link2上发送数据给AP MLD。If the multi-link operation mode contained in the first message indicates the use of the second mode, the STA MLD monitors the links link1 and link2 at the same time, and if it receives a control message on link1, it sends a response message to AP1 on link1, and Send data to AP MLD on link1; if a control message is received on link2, send a response message to AP2 on link2, and send data to AP MLD on link2.
2.2如果第一消息中包含的多链路操作模式指示使用第一模式，则AP MLD监听链路link1，如果link1空闲，则通过AP1在link1上发送数据给STA1，如果link1不空闲，则监听链路link2，如果link2空闲，则通过AP2在link2上发送数据给STA2，如果link2不空闲，则再次监听link1，如此反复。2.2 If the multi-link operation mode contained in the first message indicates that the first mode is used, the AP MLD monitors the link link1, and if link1 is idle, then sends data to STA1 on link1 through AP1, and if link1 is not idle, monitors the link Link2, if link2 is idle, send data to STA2 on link2 through AP2, if link2 is not idle, then monitor link1 again, and so on.

If it detects that link1 is idle, it sends a control message to the STA MLD on link1. If it detects that link1 is idle Not idle, but link2 is idle, then send a control message to STA MLD on link2; after receiving the control message, STA MLD sends a response message to AP MLD on the link that received the control message; after receiving the response message, AP MLD , sending data to the STA MLD on the link receiving the response message.
在一些实施例中，步骤S1001中AP MLD也可通过AP2发送第一消息给STA MLD的STA2，那么步骤S1002中，如果只监听一条链路，则监听链路link2，如果循环反复监听，则先监听链路link2，再监听链路link1。In some embodiments, in step S1001, AP MLD may also send the first message to STA2 of STA MLD through AP2, then in step S1002, if only one link is monitored, then link link2 is monitored; Monitor link link2, and then monitor link link1.
在其他一些实施例中，AP MLD可提前设置主链路和非主链路，并将这些信息发送给STA MLD，通过对链路的配置，进一步降低AP MLD的能耗。本发明实施例中，AP MLD设置链路link1为主链路，链路link2为非主链路，故AP MLD通过AP1在主链路link1上发送广播消息等其他消息。进一步地，如果有多条非主链路，则其他非主链路上的操作与上述实施例中的link2相同，本发明实施例不再详细介绍。In some other embodiments, the AP MLD may set the primary link and the non-primary link in advance, and send the information to the STA MLD, and further reduce the energy consumption of the AP MLD through link configuration.
