Abstract: This application provides a DRX configuration method, a terminal device, a network device, and a communications system. The DRX configuration method includes: receiving, by a terminal device, N discontinuous reception DRX configurations sent by a network device, where the N DRX configurations respectively correspond to N groups of carriers; and when a DRX status of the terminal device is an active state, if M groups of carriers in the N groups of carriers are activated carriers, monitoring, by the terminal device, a physical downlink control channel on a specified carrier based on M DRX configurations corresponding to the M groups of carriers. In the DRX configuration manner, the terminal device simultaneously uses a plurality of DRX configurations in an overlay manner, thereby meeting quality of service requirements of different services sent by the terminal device. In addition, the terminal device simultaneously uses the plurality of DRX configurations in an overlay manner, so as to reduce unnecessary physical downlink control channel monitoring in a process of monitoring the physical downlink control channel, thereby reducing energy consumption of the terminal device.

Abstract: The present disclosure discloses a data communication method and a device, to resolve a prior-art problem of a high latency for switching a terminal device from an idle mode to a connected mode. The method includes: prestoring, by a terminal device, a TA indication list of a group of cells; performing, by the terminal device, cell selection or reselection, and obtaining a cell identity of a cell obtained after the selection or reselection; querying, by the terminal device based on the cell identity, the TA indication list of the group of cells for a TA value corresponding to the cell identity; and if the terminal device successfully finds, in the TA indication list of the group of cells, the TA value corresponding to the cell identity, sending, by the terminal device, an uplink Radio Resource Control (RRC) message in a random access-free manner.

Abstract: Embodiments of the disclosure provides a BSR communication method and a terminal device. The communication method includes: determining, by a terminal device, a quantity of LCGs currently including to-be-reported buffer data; when determining that only one LCG includes to-be-reported buffer data, determining, by the terminal device, one of a plurality of BSR formats as a first target BSR format, where the plurality of BSR formats are a plurality of formats used by the terminal device to report different BSRs based on different ranges of amount of uplink data in a buffer; and sending, by the terminal device, a target BSR to an access network device using the first target BSR format, where the target BSR is used to indicate an amount of uplink data in a buffer of the LCG.

Abstract: A buffer status report processing method and an apparatus are disclosed. A network device determines a logical channel or a logical channel group for which a separate buffer status report BSR needs to be reported, and sends separate-BSR reporting indication information. A terminal device receives the separate-BSR reporting indication information sent by the network device, and reports the separate BSR for the logical channel or the logical channel group indicated in the separate-BSR reporting indication information. The network device receives the separate BSR reported by the terminal device, and determines, based on the separate BSR, uplink buffer data amount information corresponding to the logical channel or the logical channel group. According to the BSR processing method, resource scheduling accuracy of the network device is improved.
