Abstract: This application provides an information transmission method and an apparatus. A core network device obtains second public land mobile network (PLMN) information of a second cell before a cell handover of a terminal device. After the terminal device is handed over to a first cell, the core network device obtains first PLMN information of the first cell. When a second PLMN does not belong to a PLMN list and a first PLMN belongs to the PLMN list, the core network device sends first information to a first access network device corresponding to the first cell, where the first information includes the PLMN list, and the PLMN list includes a PLMN set that allows the terminal device to perform minimization of drive test.

Abstract: A data transmission method is provided to resolve a problem of data transmission delay in a DRX mechanism. A RAN device sends, to a terminal in a DRX active period, first grant information that is used to perform initial transmission grant for first data. The RAN device sends, to the terminal in a retransmission active time in which the terminal expects to receive a retransmission grant for the first data, second grant information that is used to perform initial transmission grant for second data. Then the RAN device and the terminal remain in an active state in an activation extension time that is after sending of the second grant information.

Abstract: The present disclosure relates to data processing methods and devices. One example method includes obtaining N correctly received radio link control (RLC) protocol data units (PDUs) in a packet data convergence protocol (PDCP) PDU, and generating the PDCP PDU based on the N correctly received RLC PDUs, where the PDCP PDU includes M RLC PDUs, N and M are positive integers, and N

Abstract: Embodiments of the present disclosure provide a scheduling method and a base station. In a cell handover process, a target base station serving a target cell receives a random access request from a terminal, sends a random access response to the terminal according to the random access request, and proactively sends an uplink grant to the terminal after sending the random access response and prior to receiving a handover complete command from the terminal. By proactively sending the uplink grant, the target base station can perform uplink scheduling for UE before cell handover is completed, so as to reduce an uplink transmission latency caused by the cell handover.
