Abstract: This application provides a method for determining a configured resource, and an apparatus. The method includes: obtaining, by a terminal device, configuration information of a configured resource from a network device, where the configured resource is a periodic resource, and the configuration information includes a periodicity parameter of the periodic resource; maintaining, by the terminal device, a sequence number for the configured resource, where the sequence number is updated when a system frame number SFN wraps around; and determining, by the terminal device, the configured resource based on the sequence number and the periodicity parameter. Based on this solution, the terminal device can determine the configured resource based on the periodicity parameter of the periodic resource, to reduce a possibility of a deviation between a configured resource position obtained through calculation and that of a resource actually required by the terminal device, thereby implementing effective configuration of the configured resource.

Abstract: A reference time determining method and apparatus are provided, to prevent aberrations in a control instruction execution time caused by inconsistency between a reference time of a terminal and a reference time of a control device in the conventional technology. In this application, the terminal may receive a plurality of pieces of time reference information sent by the network device. When the terminal receives indication information from the network device, the terminal may select, based on the indication information, one piece of time reference information from the plurality of pieces of time reference information as first time reference information. The indication information indicates the first time reference information. After determining the first time reference information, the terminal may determine the reference time of the terminal based on the first time reference information.

Abstract: A communication method includes sending, by a terminal device, first indication information to a first communication device. The first indication information indicates the first communication device to render first foreground content, and the first foreground content is to-be-displayed foreground content of the terminal device. The communication information also includes receiving, by the terminal device, first information from the first communication device. The first information comprises second foreground content and second background content. The second foreground content is obtained by rendering the first foreground content. The second background content is obtained by decoding third background content. The third background content is determined based on first background content. The first background content is to-be-displayed background content of the terminal device.

Abstract: A beam failure recovery BFR method and an apparatus are provided. The method includes: A terminal receives indication information of a first threshold and a second threshold, where the second threshold is used to determine that a beam failure occurs on an access network device. The terminal collects statistics on quantities of beam failure instance times of one or more access network devices that communicate with the terminal based on beams in a cell; and performs beam recovery on an access network device whose quantity of beam failure instance times is greater than or equal to the first threshold and less than the second threshold. The method and the apparatus in this application can further reduce a possibility of the beam failure, improve network reliability, and avoid beam failures on a plurality of devices in the cell at the same time.
