Abstract: Example communication methods and apparatus are described. One example method includes obtaining first indication information by a terminal apparatus, where the first indication information is used to indicate a first time domain resource to be used by the terminal apparatus to send or receive first information on a first link. The terminal apparatus obtains second indication information, where the second indication information is used to indicate a second time domain resource to be used by the terminal apparatus to send or receive second information on a second link. When the first time domain resource overlaps with the second time domain resource, the terminal apparatus sends or receives the first information on the first time domain resource, and/or cancels receiving or sending of the second information on the second time domain resource.

Abstract: In a communication method, a terminal may send first information to a network device on a first carrier, to trigger measurement on at least one second carrier or at least one beam of at least one second carrier. Subsequently, the terminal may send or receive a reference signal on the at least one second carrier or the at least one beam.

Abstract: A communication method and apparatus are provided. The method includes: receiving configuration information from a network device, where the configuration information indicates an occasion and/or a period for sending a measurement signal on a second uplink carrier; obtaining signal quality or signal strength on a downlink carrier associated with a first uplink carrier, or signal quality or signal strength on a downlink resource on a first uplink carrier; and when a first condition is met, sending the measurement signal on the second uplink carrier by occupying the occasion and/or the period; or when a first condition is not met, determining not to send the measurement signal on the second uplink carrier by occupying the occasion and/or the period.

Abstract: A network slice selection method, a radio access device, and a terminal, where the method includes obtaining, by a radio access network (RAN) device, network slice information, sending, by the RAN device, a first message to a terminal, where the first message includes the network slice information, receiving, by the RAN device, a first access request message from the terminal after the terminal selects, based on the network slice information, first attribute information of a first network slice to be accessed by the terminal, and selecting, by the RAN device based on the first attribute information of the first network slice, a second network slice to be accessed by the terminal. The method enables an operator to flexibly configure a network slice, and reduces a communication latency and signaling overheads in a process in which a terminal selects a network slice.

Abstract: A uplink information sending method is provided, including: sending, by a base station, at least one of first transmission indication information of first uplink information and second transmission indication information to user equipment UE, where the first transmission indication information includes a subframe and/or a carrier on which the base station instructs the UE to send the first uplink information; and the first transmission indication information and/or the second transmission indication information are/is used to indicate UE behavior when a collision occurs. The uplink information sending method provided in the present invention is used to mitigate impact of a carrier collision on processing efficiency of the UE.

Abstract: With development of communications technologies, an internet-of-vehicles technology for vehicle-to-everything (V2X) communication is proposed. In this application, a third device receives first information and/or sidelink control information. The first information includes indication information of a first resource set, the first resource set is for receiving data, the sidelink control information includes indication information of a second resource set, and the second resource set is for sending data. The third device determines an available resource in the first resource set, and/or determines an available resource in the second resource set. The method can resolve a hidden node problem and an exposed node problem on a sidelink.

Abstract: A random access method and an apparatus include performing listen before talk (LBT) on a first carrier, detecting a first signal on the first carrier when the terminal determines, through the LBT, that the first carrier is in a busy state, where the first carrier includes an unlicensed carrier, the first signal includes a first preamble signal or indication information, and the indication information indicates that the first carrier sends the first preamble signal, and sending a second preamble signal on the first carrier to attempt to access a base station when the terminal detects the first preamble signal or the indication information.

Abstract: A transmission direction configuration method, a device, and a system are described that relate to the field of communications technologies. A terminal device receives a first indication information from a network device, the first indication information indicates a configuration of uplink and downlink transmission directions. The configuration describes types, a number, and a distribution of resource elements comprised in one period. Moreover, the resource granularity comprises a time domain granularity, the time domain granularity comprises (OFDM) symbol. The types of the resource elements comprise at least one of an uplink resource element, a downlink resource element, or a switch resource element between the downlink resource element and the uplink resource element. An information transmission is performed that is indicated by the first indication information, of the uplink and/or downlink transmission directions.
