Abstract: A transmit power determining method and apparatus are disclosed. The method includes: calculating, channel state information of a channel between the wireless access point device and a station device within a particular time range; comparing, by the wireless access point device, the channel state information with pre-obtained reference channel state information, and adjusting, according to a result of the comparison, a transmit power currently used by the wireless access point device; and sending, by the wireless access point device to the station device by using a transmit power after the adjustment, a message carrying data. During implementation of the present disclosure, a transmit power for sending data can be adjusted according to channel state information corresponding to a channel between a wireless access point device and a station device, thereby avoiding unnecessary power overheads and a waste of energy.

Abstract: A Wi-Fi communication method, apparatus, and system are provided, relate to the field of communication technologies, and are used to reduce a latency and latency jitter of Wi-Fi communication. The method includes: An access device sends a scheduling signal to a station device, where the scheduling signal is used to schedule a scheduling frequency band, or a scheduling frequency band and a contention frequency band, the contention frequency band is an existing frequency band for Wi-Fi communication, the scheduling frequency band is different from the contention frequency band, and the scheduling frequency band may not be an existing frequency band for Wi-Fi communication; and the access device communicates with the station device on the frequency band scheduled by using the scheduling signal, for example, transmits uplink data or downlink data on the scheduling frequency band, or the scheduling frequency band and the contention frequency band.

Abstract: The present invention provides a method for handover between access points, and terminal equipment. The method includes: when performing information transmission with a first access point AP on a first frequency band, determining whether the terminal equipment needs to establish a connection with a second AP which is a second frequency band; determining, by the terminal equipment, whether the first AP and the second AP are corresponding to a same dual-band radio access device; sending, by the terminal equipment, a connection request to the second AP when maintaining a protocol layer connection with the first AP; and establishing, by the terminal equipment, the connection with the second AP when the second AP send feedback. In the method, duration required by a process of handover between access points can be reduced, and a user is made not perceive the handover process, thereby improving user experience.
