Abstract: A timer control method includes a receiving device that performs re-establishment or data recovery on a Packet Data Convergence Protocol (PDCP) layer of the receiving device. The PDCP layer stops the running of a reordering timer of the PDCP layer when the reordering timer is in a running state, where the reordering timer enables the PDCP layer to wait to receive a lost data packet. Because the reordering timer is stopped from running rather than expires, the PDCP layer does not update a value of RX_DELIV.

Abstract: When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and a PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity.

Abstract: A measurement configuration determining method includes receiving, by a terminal device, a first message from a network device. The first message includes a first relationship, the first relationship indicates an association relationship between an index of a reference signal and measurement configuration information. The measurement configuration information is adapted for the terminal device to perform a measurement and the terminal device determines the measurement configuration information based on the index.

Abstract: A data transmission method and related devices. The method includes: handing over a first terminal device from a second terminal device to a network device; receiving, by the first terminal device, a first packet data convergence protocol (PDCP) data packet sent by the network device; and if the first PDCP data packet is a target PDCP data packet, submitting, by the first terminal device, a second PDCP data packet, where the target PDCP data packet is a PDCP data packet sent by the network device based on a transmission status report, and the transmission status report is a status report sent by the first terminal device or the second terminal device to the network device.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.
