Abstract: Embodiments of this application disclose a projection data processing method, to reduce a delay in a wireless projection process. In the embodiments of this application, the method includes: A projection transmit end obtains network status information, and determines a target resolution of an image to be projected based on the network status information; and then determines a to-be-synthesized layer based on whether the image is in a full-screen scenario. Therefore, an amount of data to be sent during projection can be reduced, and a projection delay can be reduced. In addition, a projection receive end can perform super-resolution on the image, to avoid image quality damage caused by reducing the amount of data sent by the transmit end. This solution reduces the projection delay and ensures projection image quality to improve user experience.

Abstract: A control method and an apparatus for network admission, which can control network admission of a wireless termination point (WTP) in a condition that a live network is not upgraded. In the method, an access controller (AC) that has a network admission control function receives a join request packet from a WTP and establishes a Control and Provisioning of Wireless Access Points (CAPWAP) connection with the WTP. If the CAPWAP connection between the AC and the WTP is successfully established, the AC enables permission of the WTP. In another control method for network admission disclosed in the present application, an AC receives a join request packet from a WTP and establishes a CAPWAP connection with the WTP. A network admission end enables permission of the WTP according to a result from the AC that the connection between the AC and the WTP is successfully established.

Abstract: A channel quality measurement method and apparatus are described. The method can include a network device sending configuration information to a terminal device. The configuration information configures a downlink carrier set. The terminal device determines a first downlink carrier from the downlink carrier set. The terminal device sends a random access process message 3 (Msg3) to the network device. The random access process message 3 includes first information. The first information includes information indicating channel quality of the first downlink carrier. The channel quality provides information about a first repetition level to the network device. The first repetition level is a minimum repetition level required when transmission performed on a downlink channel based on a preset transmission parameter meets a preset block error rate.
