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，延迟和抖动更少，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。在2.4GHz，5GHz和6GHz频段运行的802.11兼容设备。Given the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency and jitter, and better 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. 802.11 compliant devices operating on the 2.4GHz, 5GHz and 6GHz bands.

In some other embodiments, the parameter may not be included in the power saving mode enabling message, and may also indicate enabling the power saving mode.
Enabled link bitmap：启用链路指示，如将在省电模式下处于激活状态的链路对应的比特位设置为1，将在省电模式下处于休眠状态的链路对应的比特位设置为0，示例地，将Enabled link bitmap的值设置为011，表示在省电模式下处于激活状态的链路为link1和link2，而link3处于休眠状态。在其他一些实施例中，也可直接包含链路标识，用于指示在省电模式下处于激活状态的链路，如包含链路标识link1和link2，则表示在省电模式下处于激活状态的链路为link1和link2，而link3处于休眠状态。Enabled link bitmap: Enable link indication, such as setting the bit corresponding to the link that is active in power saving mode to 1, and setting the bit corresponding to the link that is dormant in power saving mode to 0, For example, if the value of the Enabled link bitmap is set to 011, it means link1 and link2 are activated in the power saving mode, and link3 is in a dormant state. In some other embodiments, link identifiers may also be included directly to indicate links that are activated in the power saving mode. For example, link identifiers link1 and link2 are included to indicate links that are active in the power saving mode The links are link1 and link2, while link3 is dormant.

Link2TID mapping for MLPS mode(可选)：链路与业务的映射关系，如果AP MLD1同意省电模式启用消息中指示的映射关系，则响应消息中可不包含该参数；如果AP MLD1不同意省电模式启用消息中指示的映射关系，则响应消息中包含该参数，用于指示建议的省电模式下的链路与业务的映射关系。Link2TID mapping for MLPS mode (optional): The mapping relationship between links and services. If AP MLD1 agrees with the mapping relationship indicated in the power saving mode enabling message, this parameter may not be included in the response message; if AP MLD1 does not agree with the power saving mode If the mapping relationship indicated in the enabling message, the response message contains this parameter, which is used to indicate the mapping relationship between the link and the service in the suggested power saving mode.

Data transmission takes place on the active link. If the power saving mode enabling message contains the parameter TID2Link mapping for MLPS mode, data transmission is performed on the active link according to the mapping relationship indicated by the parameter; if the power saving mode enabling message does not contain the parameter TID2Link mapping for MLPS mode , data transmission is performed on the active link according to the mapping relationship between the service and the link before entering the power saving mode or using the default mapping relationship.
如果AP MLD1不同意省电模式启用消息中指示的业务与链路的映射关系，即省电模式启用响应消息中包含参数TID2Link mapping for MLPS mode，则STA MLD1再次发送省电模式启用消息给AP MLD1，消息中包含参数TID2Link mapping for MLPS mode，且该消息中参数TID2Link mapping for MLPS mode的值与接收到的省电模式启用响应消息中参数TID2Link mapping for MLPS mode的值相同；AP MLD1接收到该新的省电模式启用消息后，发送指示同意启用省电模式的省电模式启用响应消息给STA MLD1；STA MLD1接收同意启用省电模式的省电模式启用响应消息，与AP MLD1根据该新的省电模式启用消息中参数TID2Link mapping for MLPS mode指示的映射关系在处于激活状态的链路上进行数据传输。If AP MLD1 does not agree with the mapping relationship between services and links indicated in the power saving mode enabling message, that is, the power saving mode enabling response message contains the parameter TID2Link mapping for MLPS mode, then STA MLD1 sends the power saving mode enabling message to AP MLD1 again , the message contains the parameter TID2Link mapping for MLPS mode, and the value of the parameter TID2Link mapping for MLPS mode in the message is the same as the value of the parameter TID2Link mapping for MLPS mode in the received power saving mode activation response message; AP MLD1 receives the new STA MLD1 receives the power saving mode activation response message agreeing to enable the power saving mode, and communicates with AP MLD1 according to the new power saving mode.

For example, when the user browses the web, STA MLD1 enters the power saving mode, and then the user starts to play games or watch high-definition videos, then STA MLD1 needs to increase the activated link, or replace the original low-speed link with a high-speed link, or simply exit the power saving mode and activate all links. Examples of activation methods are as follows:

Optionally, the parameter Switch delay can also include the parameter A2DSwitchdelay used to indicate the change delay from the active state to the dormant state (turn off the transceiver), and the parameter A2DSwitchdelay used to indicate the change delay from the dormant state to the active state (open transceiver + timing synchronization) The parameter D2Aswitchdelay, where the delay indicated by A2DSwitchdelay is shorter than the delay indicated by D2Aswitchdelay, because it is faster to turn off the transceiver, and timing synchronization is required after the transceiver is turned on, and the delay will be longer.
