摘要： A resource determining method includes that a first terminal obtains transmission information from a second terminal, wherein the transmission information is used to indicate a first sidelink resource. The first terminal determines a second sidelink resource according to the transmission information, wherein a time range of the second sidelink resource does not overlap that of the first sidelink resource. The first terminal sends a first data to the second terminal on a sidelink resource of the second sidelink resource, wherein the first sidelink resource comprises a sidelink resource on which a second data is received by the second terminal.

摘要： A data transmission method and apparatus are applicable to fields such as V2X, intelligent driving, and connected vehicles. A probability of a collision between a high-priority PSSCH and a low-priority PSSCH is reduced, thereby improving QoS of the high-priority PSSCH. The method includes: obtaining resource pool configuration information including first resource pool information and second resource pool information, where the first resource pool information indicates a first resource pool, and the second resource pool information indicates a second resource pool; obtaining a first priority value corresponding to a physical sidelink shared channel PSSCH; when the first priority value is less than a first priority threshold, determining, in a partial-sensing-selection-based resource determination mechanism and/or a random-selection-based resource determination mechanism in the first resource pool, a resource for sending the PSSCH.

摘要： This application provides a method for waking up a terminal, a terminal, and a network device. In technical solutions provided in this application, a network device determines, from a plurality of wake-up signals that can wake up a to-be-woken-up terminal and that need to be monitored by the to-be-woken-up terminal for one PO, a target wake-up signal of the to-be-woken-up terminal, and sends the target wake-up signal to the to-be-woken-up terminal. If the terminal detects, for the one PO, at least one wake-up signal of the plurality of wake-up signals that can wake up the terminal and that need to be monitored by the terminal, the terminal monitors a downlink control channel at the PO.

摘要： The present disclosure relates to methods and terminal devices for detecting a wake-up signal. A terminal device sends first information to a network device, where the first information indicates a reported gap, receives second information sent by the network device, and determines a configuration condition of a first gap and a configuration condition of a second gap based on the second information. The terminal device determines a target gap based on the reported gap, the configuration condition of the first gap, and the configuration condition of the second gap, and detects a wake-up signal at a detection position before a start position of the first paging opportunity in a paging time window, where the detection position is determined based on the target gap and maximum duration of the wake-up signal.

摘要： A monitoring method and an apparatus are provided. The method includes transmitting, by a terminal device, first information based on a first repetition number, where the first repetition number is less than or equal to a second repetition number, and the second repetition number is a maximum repeat transmission number of the first information. The method also includes determining, by the terminal device, a scheduling end moment of the first information based on the second repetition number, where the scheduling end moment of the first information is a transmission end moment of the first information when the first information is transmitted based on the second repetition number. The method further includes starting or restarting, by the terminal device, a timer at the scheduling end moment of the first information, and monitoring a PDCCH search space before the timer expires or stops.
