    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.

    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.

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. In this way, the RAN device may perform initial transmission by using a retransmission active time, so as to extend an active time.

    Abstract: Data packet retransmission by a radio link control (RLC) protocol entity of a transmit end is described herein. The retransmission includes sending a target sequence number and a first data packet to a MAC entity of the transmit end and recording a quantity of times the target sequence number is transmitted to the MAC entity of the transmit end at an RLC layer. In accordance with receiving the target sequence number and a negative acknowledgement that are sent by the MAC entity, obtaining the RLC layer transmission count corresponding to the target sequence number. In accordance with determining the RLC layer transmission count is less than an RLC layer transmission threshold, sending a retransmission instruction based on the first data packet to the MAC entity. In accordance with a retransmission condition at the RLC layer being met, the RLC entity of the transmit end triggers retransmission at the RLC layer.

    Abstract: A communications method includes: sending a scheduling request to a terminal device through a PDCCH, where the scheduling request indicates the terminal device to send data to a network device based on a preset time interval; in response to not receiving the data that is sent by the terminal device through a PUSCH, determining, based on measurement gap configuration information of the terminal device, whether a time point at which the terminal device does not send the data is within a measurement gap window; and if it is determined that the time point at which the terminal device does not send the data is within the measurement gap window, sending, to the terminal device, a redundancy version number used for a next HARQ retransmission.
