Abstract: A data transmission method may include a first control apparatus sending first indication information to a second control apparatus. The first indication information is used to indicate to measure link quality between the second control apparatus and at least one terminal device. The second control apparatus generates first data. The second control apparatus sends the first data to the at least one terminal device based on the first indication information. The first data measure the link quality between the second control apparatus and the at least one terminal 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.

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.
