Abstract: In an uplink synchronization method, a network device may send a timing advance (TA) of a normal uplink (NUL) and a TA of a supplementary uplink (SUL) to a terminal device. The terminal device may adjust, based on the TA of the NUL, time for sending uplink data through the NUL, and adjust, based on the TA of the SUL, time for sending data through the SUL. The terminal device may separately adjust the time for sending uplink data through the NUL and the time for sending uplink data through the SUL.

Abstract: A measurement configuration method and an apparatus are provided. The method includes: A network device sends first information to a terminal device. The first information includes configuration information of an SCC. The network device sends second information to the terminal device. The second information includes configuration information of a first measurement window, and the second information is used to enable the terminal device to switch, when supporting CA, from performing cell measurement in a measurement window-free measurement manner to performing cell measurement by using the first measurement window. A carrier included in the CA includes the SCC configured based on the first information. According to the foregoing method, after the network device configures the SCC, the terminal device may switch, based on the second information, from performing cell measurement in the measurement window-free measurement manner to performing cell measurement by using the first measurement window.

Abstract: This specification provides a resource determining method and an apparatus, to optimize sidelink transmission performance. In this specification, a first communication apparatus may receive preferred resource information and/or non-preferred resource information, determine a transmission resource based on received resource information and a type of the first communication apparatus, and perform sidelink transmission by using the transmission resource. First resource information can indicate a high-interference or high-usage resource and/or a low-interference or low-usage resource. The first communication apparatus can select, based on the type of the first communication apparatus, a resource with relatively low interference to perform sidelink transmission. This improves sidelink transmission performance.
