Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A network device determines energy saving information of a first cell, where the energy saving information indicates a compensation value corresponding to a first energy saving state, and when the first cell is in the first energy saving state, the compensation value is used to compensate a measurement value of an SSB associated with the compensation value; and sends the energy saving information to a terminal device. According to the method, the network device may perform an energy saving operation on the SSB (for example, reducing a transmit power of the SSB), and send the energy saving information of the first cell to the terminal device.

Abstract: This application provides a data transmission method, an apparatus, and a system. The method includes: A source network device performs cascading processing on at least two data units to obtain a first data packet, where data included in the at least two data units belongs to a same radio bearer or quality of service flow of a terminal device, and the first data packet is a packet data convergence protocol PDCP layer data packet or a service data adaptation protocol SDAP layer data packet; and sends the first data packet to a target network device through a first tunnel. According to the foregoing method, a plurality of data units are cascaded to obtain one data packet, so that header overheads of the cascaded data packet can be reduced, lossless handover under a cascading function can be implemented, and a cascading gain can be obtained.

Abstract: A communication method for a terminal device includes receiving a conditional handover (CHO) command from a source network device. The communication method also includes selecting, by the terminal device, a cell in response to a radio link failure (RLF) in a source cell before the terminal device determines a target cell. The target cell is determined according to the CHO command. The communication method additionally includes sending first information to a network device. The first information includes a first parameter. The first parameter is related to a CHO failure caused by the RLF in the source cell.

Abstract: A minimization of drive tests (MDT) method and apparatus includes: a network device sends MDT configuration information to a terminal, where the MDT configuration information includes an MDT measurement parameter of a shared spectrum; and the terminal performs MDT on the shared spectrum based on the MDT configuration information to obtain a measurement report, and sends the measurement report to the network device. The MDT may be performed on a shared spectrum to obtain a measurement report. The measurement report may better reflect an application status of the shared spectrum, to help optimize a network device that performs communication by using the shared spectrum.

Abstract: Embodiments of this application provide example communication methods and apparatuses. One example method includes receiving, by a first network device, a first request message and uplink data from a terminal, where the first request message is for requesting to resume a suspended radio resource control (RRC) connection. The first network device can then send a second request message to a second network device based on the first request message and the uplink data, where the second network device is a network device previously serving the terminal, and the second request message includes information about the uplink data, where the second request message is for requesting the second network device to release a first data channel between the second network device and a core network device, or the second request message is for requesting the second network device to send a context of the terminal to the first network device.

Abstract: The present disclosure relates to radio resource control (RRC) reestablishment methods and apparatuses. In one example method, a terminal device selects a target cell, where the target cell supports an expected network slice. The terminal device sends an RRC reestablishment request message by using the target cell. The expected network slice may include a network slice that the terminal device expects to access, or a network slice corresponding to a PDU session established by the terminal device by using a last serving access network device of the terminal device. The terminal device may select the target cell within a preset time period. For example, the terminal device starts a first timer when the terminal device starts selecting the target cell, and selects the target cell during running of the first timer. The first timer may be specific to one or more network slices or all network slices.

Abstract: A communication method and a related apparatus. The method includes: a terminal device receives first indication information sent by a network device. When the first indication information indicates a channel unoccupied time of the network device, within the channel unoccupied time, the terminal device skips performing downlink measurement, skips receiving the downlink data, skips sending a HARQ feedback corresponding to the downlink data, or determines that a downlink measurement result is invalid. Unnecessary measurement can be reduced, a downlink measurement failure caused because a network side does not preempt a channel can be excluded, and measurement efficiency and accuracy of a measurement result can be improved.

Abstract: The disclosure provides communication methods and apparatuses. One example method includes that a terminal device sends a random access request to a network device, and the terminal device receives a random access response to the random access request that comprises first configuration information from a network device. The first indication information indicates not to perform channel access or the first indication information indicates that a channel access type is channel access without random back-off or channel access with random back-off with variable size of contention window. The terminal device sends an uplink message to the network device based on the first indication information, where the uplink message is carried on a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).
