背景技术
802.11be网络，也称为Extremely High Throughput(EHT)网络，通过一系列***特性和多种机制增强功能以实现极高的吞吐量。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)。
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。用户期望改进与时敏网络(TSN)的集成，以支持异构以太网和无线LAN上的应用程序。802.11be网络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。
发明内容
即使是需要高速率进行数据传输的终端，也并不是时时都在执行高速率传输需求的业务。比如手机或电脑在进行高清视频传输的时候，可能需要极高的数据传输速率，然而在其他时候，并不需要有高速传输数据的资源，如果不能动态的进行数据传输链路的管理，那么无线资源的使用率并不能如预期提高，相反还会造成极大的浪费。

Capability Info：长度16个bit的Capability Information性能信息位，发送Beacon信号的时候，它被用来通知各方，该网络具备哪种性能。因为新演进的802.11be网络要求能兼容之前版本的网络终端，因此该字段用于通知之前版本网络兼容的基本能力，例如是否支持即时Block Ack，是否支持QoS设置，是否支持短导码，是否支持短slot time等。
SSID：Service Set Identifier，服务集标识。

Link set for STR：用于指示在支持多链路同时独立接收和发送的模式下终端可以进行多链路同时独立接收和发送的链路集，示例地，这个链路集可以是基于链路的，例如{link1，link2}，link1和link2分别指示链路一和链路二，也可以是基于操作频段的，例如{2.4GHZ，5GHZ}，或{2.4GHZ，6GHZ}，也可以是基于每个频段的操作波段，波段由中心频率和带宽两个参数指示，例如{(2.45GHZ，40MHZ)，(6.45GHZ，160MHZ)}。
