Abstract: Example radio link monitoring methods and apparatus are described. One example method includes performing radio link monitoring (RLM) in a second bandwidth part (BWP) by a terminal device. The terminal device receives first switching information from a network device that is used to indicate that an active BWP includes a first BWP, and switches from the second BWP to the first BWP based on the first switching information. The terminal device removes a measurement result obtained by performing RLM in the second BWP, where the measurement result includes a quantity N1 of one or more out of synchronization (OOS) states or a quantity N2 of one or more in synchronization (IS) states. RLM is performed in the first BWP.

Abstract: This application relates to a resource selection method and an apparatus. A first resource is selected for first data from candidate resources in a resource pool. At least one resource is selected for the first data from the candidate resources other than the first resource based on the first resource and a first gap. A quantity of candidate resources is greater than or equal to X % of a quantity of all resources in the resource pool, where a value of X may be set based on a target quantity of resources, based on a target quantity of resources and a first time gap, based on a target quantity of resources, a first time gap, and a first frequency gap, or based on a service priority. The value of X may be set based on different factors, to meet a resource selection requirement.

Abstract: This application provides a channel measurement method and an apparatus, which may be used in a field such as vehicle-to-everything V2X, smart internet of vehicles, autonomous driving, or an unmanned driving. In a sidelink channel report procedure, a transmit end apparatus for sidelink communication indicates one or more candidate time intervals to a receive end apparatus. The receive end apparatus may attempt to obtain an available PSSCH for sending a channel measurement report on one or more time domain resources corresponding to the one or more candidate time intervals.

Abstract: An information sending method, an information receiving method, a device, and an apparatus are disclosed. The information sending method includes: determining, by a first terminal device based on first information, at least one of a quantity or a position of m DMRSs carried on a PSSCH, where m is a positive integer, and the first information includes at least one of a subcarrier spacing, duration of the PSSCH, or a channel coherence time; and sending, by the first terminal device, the m DMRSs to a second terminal device. In addition, when the DMRS on the PSSCH is determined, a reference channel coherence time may be selected. For example, a time interval between two configured adjacent DMRSs may be less than or equal to the channel coherence time.

Abstract: A time-to-digital converter including N stages of converting circuits, where N≥2, and N is an integer. Each stage of converting circuit includes a first delayer and an arbiter; an output end of the first delayer in each stage of converting circuit outputs a delayed signal of the stage of converting circuit; and the arbiter in each stage of converting circuit receives a sampling clock and the delayed signal of the stage of converting circuit, and compares the sampling clock with the delayed signal to obtain an output signal of the stage of converting circuit. Output signals of the N stages of converting circuits form a non-linear binary number, to indicate a time difference between a clock signal and a reference signal.

Abstract: Embodiments relate to a data transmission method. A relay node receives information that is about an SCMA codebook used by the relay node and that is sent by a destination node. The relay node receives two or more source signals sent by two or more source nodes. The relay node performs network coding on the received two or more source signals. The relay node performs SCMA codebook mapping on a signal obtained after the network coding, so as to obtain at least two modulation symbols. The relay node sends to the destination node, the at least two modulation symbols obtained after the SCMA mapping.
