Abstract: A method may be applied to a terminal device that supports a first communication system and a second communication system. The first communication system corresponds to a first user identity, and the second communication system corresponds to a second user identity. The method includes: a terminal device receiving a first message in a first communication system, where the first message indicates to perform DAPS handover between a source cell and a target cell in the first communication system. In response to determining that a capability available for the first communication system cannot support the DAPS handover, the terminal device suspends communication with the source cell in the first communication system, and is handed over to the target cell in the first communication system.

Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.

Abstract: A communication method and apparatus are provided. The method may be applied to a terminal and a network device. In the method, the network device first sends first indication information before sending a paging message, where the first indication information is used to indicate whether at least two terminals in an RRC_IDLE state or an RRC_INACTIVE state need to receive the paging message. In this way, after each of the at least two terminals receives the first indication information, the terminal may determine, based on the first indication information, whether the terminal needs to receive the paging message. If determining that the terminal needs to receive the paging message, the terminal may detect and receive the paging message on a corresponding time-frequency resource after the network device sends the paging message.

Abstract: Embodiments of the present invention provide a data transmission method and an apparatus, and relate to the field of communications technologies. The method includes: obtaining, by a terminal, first indication information of an uplink resource used for sending uplink data or uplink control information. The first indication information of the uplink resource includes information used to indicate whether the uplink resource is a type 1 uplink resource or a type 2 uplink resource. The type 1 uplink resource includes at least one subcarrier in a frequency domain, where when a subcarrier quantity of subcarriers is greater than or equal to 2, the subcarriers are orthogonal to each other, and a subcarrier spacing is 3.75 kHz; or the type 1 uplink resource includes at least one sub-channel in a frequency domain, where a bandwidth of each sub-channel is approximately 3.75 kHz.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives an identifier of a filtering protocol version from an access network device, and then sends first capability information of the terminal device to the access network device based on the filtering protocol version. In this method, the terminal device may report capability information based on the filtering protocol version sent by the access network device. Compared with a manner in which the terminal device directly reports the capability information, this method can effectively reduce a communication problem caused by mismatch between a protocol version supported by the terminal device and a protocol version supported by the access network device and/or a protocol version supported by a core network device.

Abstract: A communication method and device for reducing power consumption of receive user equipment (RX UE) are provided. The method includes: when there is no reserved resource used to retransmit first transmission on a sidelink, a first communication device and/or a second communication device starts a first timer, and/or stops a second timer; or when there is a reserved resource used to retransmit first transmission on a sidelink, a first communication device and a second communication device stop a second timer. In this way, the first communication device and the second communication device can jointly control, by using the first timer and the second timer, the first communication device to receive data on the sidelink, so that the first communication device may not keep monitoring SCI that is associated with a HARQ process corresponding to the first transmission.
