Abstract: Embodiments of this application provide a Wi-Fi communication method and apparatus, and relate to the wireless communication field. A station may obtain detection information including a start time point at which an access point actually sends a beacon packet to the station for one time, obtain a low power consumption parameter based on the detection information and a first time interval, and receive the beacon packet from the access point based on the low power consumption parameter. The low power consumption parameter includes an actual wakeup periodicity of the station and an actual receive window length within which the station receives the beacon packet, or the low power consumption parameter includes an actual wakeup periodicity of the station, and the actual wakeup periodicity of the station is greater than a preconfigured wakeup periodicity of the station.

Abstract: Embodiments of the present disclosure provide a method, a device and a system for evaluating a user experience value of video quality. The method is: acquiring an uplink packet of a user equipment for requesting to watch an OTT video, where the uplink packet is transmitted by the user equipment to a video server storing the OTT video and carries request information of the user equipment on the OTT video; acquiring a downlink packet corresponding to the uplink packet, where the downlink packet is transmitted by the video server to the user equipment and carries the OTT video, and the OTT video is transmitted by the video server according to the request information in the uplink packet; buffering the downlink packet; and in response to determining that the buffered downlink packet satisfies a resolving condition, resolving the OTT video in the buffered downlink packet to generate a user experience value.

Abstract translation: 本公开的实施例提供了用于评估视频质量的用户体验值的方法，设备和系统。 该方法是：获取请求观看OTT视频的用户设备的上行分组，其中上行分组由用户设备发送到存储OTT视频的视频服务器，并在OTT视频上携带用户设备的请求信息 ; 获取对应于上行链路分组的下行分组，其中下行分组由视频服务器发送给用户设备并携带OTT视频，OTT视频由视频服务器根据上行分组中的请求信息发送; 缓冲下行数据包; 并且响应于确定所缓冲的下行链路分组满足解析条件，解析所缓冲的下行链路分组中的OTT视频以产生用户体验值。
