Abstract: A communication method and an apparatus are provided, to resolve a problem of low data transmission efficiency. The method includes: in response to receiving a paging message from a terminal device, a terminal device determines, based on a preconfiguration and/or the paging message, a first physical uplink shared channel (PUSCH) resource used to transmit a paging response, and sends the paging response to the access network device on the first PUSCH resource, where the paging response carries identity authentication information of the terminal device. After the access network device or a core network successfully performs identity authentication on the terminal device, downlink data transmission can be performed. Compared with a manner in which downlink data transmission can be performed only after a radio resource control (RRC) connection is set up or resumed, this manner can improve data transmission efficiency.

Abstract: A signal transmission method includes receiving configuration information from a network device. The configuration information is used to indicate a serving cell that is allowed or forbidden to be used by a terminal for a first service or first control information. The method also includes adjusting the serving cell that is allowed or forbidden to be used by the terminal for the first service or the first control information. The method further includes transmitting the first service or the first control information by using an adjusted serving cell.

Abstract: An Ethernet header compression method and apparatus and an Ethernet header decompression method and apparatus. After receiving an Ethernet frame including a first to-be-compressed field, a compression end compresses an Ethernet header of the Ethernet frame based on a first correspondence including first compression information and a value of the first to-be-compressed field and the first compression information. Correspondingly, a decompression end decompresses an Ethernet header of a compressed Ethernet frame based on the first correspondence when receiving the compressed Ethernet frame. In the embodiments of this application, because the Ethernet header of the Ethernet frame is compressed, communication resources is saved.

Abstract: This application provides a data transmission method and apparatus. A terminal: receives a first uplink grant from a network device; sends first uplink data in to-be-sent data to the network device by using the first uplink grant; receives a second uplink grant from the network device; and sends second uplink data to the network device by using the second uplink grant, where the second uplink data is at least a part of uplink data in the to-be-sent data except the first uplink data, where the terminal is in a first state, and where the first state includes an idle state or an inactive state. The embodiments of this application help reduce a latency in a data transmission process.

Abstract: The present disclosure relates to time synchronization methods and apparatus. In one example method, a terminal receives a system information block (SIB) sent by a distributed unit (DU), where the SIB is generated by the DU, the SIB includes time information, and the time information indicates a moment corresponding to a boundary of a system frame number (SFN) at which an end boundary of a system information (SI) window for sending the SIB is located, or indicates a moment corresponding to a boundary of an SFN immediately after an end boundary of an SI window for sending the SIB. The UE processes the time information to obtain a time reference.
