A method and apparatus for autonomous changing for dormant bandwidth part in a wireless communication system is provided. A wireless device configures a cell group including a certain cell on which a PUCCH is configured. A wireless device activates a dormant BWP of the certain cell to be an active BWP of the certain cell, wherein no PDCCH is configured on the dormant BWP. A wireless device switches the active BWP of the certain cell from the dormant BWP to another BWP upon triggering the scheduling request procedure, wherein at least one PDCCH is configured on the other BWP.

Embodiments of this application provide a resource indication information transmission method, a device, and a system, which are applicable to fields such as internet of vehicles, intelligent connected vehicle, assisted driving, and intelligent driving. In an example method, a first terminal device determines X sets of candidate single-time-unit resources based on a number of sub-channels to be used by a second terminal device for physical sidelink shared channel (PSSCH) and/or physical sidelink control channel (PSCCH) transmission, and indicates, to the second terminal device, K candidate single-time-unit resources whose time domain locations are in a first time window in the X sets of candidate single-time-unit resources. The second terminal device determines a first time-frequency resource based on the K candidate single-time-unit resources. The first time window is a time window included in a selection window corresponding to at least one of the X sets of candidate single-time-unit resources.

This application relates to a communication method, apparatus, and system, and is applicable to fields such as internet of vehicles, intelligent driving, assisted driving, and intelligent connected vehicles. A first terminal apparatus detects sidelink control information from at least one second terminal apparatus to determine a first time-frequency resource. The first terminal apparatus sends first information to a third terminal apparatus, to trigger determining of second information. The first terminal apparatus receives the second information from the third terminal apparatus, to indicate a second time-frequency resource. The first terminal apparatus determines the third time-frequency resource based on the second time-frequency resource and the first time-frequency resource. The first terminal apparatus may use both a sensing result of the first terminal apparatus and a sensing result of the third terminal apparatus as consideration factors to select a resource for sending data, to improve signal received quality.

The present disclosure relates to a resource allocation method and a terminal. The resource allocation method includes: transmitting, by a first terminal, first information to a second terminal. The first information instructs the second terminal to allocate a sidelink transmission resource to the first terminal. According to an embodiment of the present disclosure, the sidelink transmission resource is allocated by the terminal to reduce interference in sidelink transmissions of individual terminals. In addition, compared with applying for a transmission resource from a network, the method can reduce delay, shorten allocation time, and improve allocation efficiency.
