    Abstract: This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated. Because both the bearer configuration of a bearer of the terminal and the initial status of the bearer configuration of the terminal are indicated, communication efficiency is improved.

    Abstract: A scheduling request (SR) configuration method and sending method, and a corresponding apparatus are provided, to resolve a prior-art problem of a scheduling request configuration method and sending method, and a corresponding apparatus. The scheduling request configuration method includes: receiving, by a user equipment (UE), control signaling sent by a network device, where the control signaling is used to configure, for the UE, an SR configuration associated with at least one logical channel and at least two SR resource configurations associated with the SR configuration, and the SR resource configurations indicate physical resources used to signal an SR associated with the at least one logical channel; and signaling, by the UE based on a physical resource indicated by one of the at least two SR resource configurations, an SR associated with one of the at least one logical channel.

    Abstract: This application provides a communication method, a communications device, and a network device. When a beam failure occurs in a secondary cell of the communications device, the communications device sends a beam failure recovery request to the network device by using a PUCCH or a MAC CE, and determines an active state time of DRX based on a status of the beam failure recovery request. The communications device may also determine a stopping time of an uplink retransmission timer based on a running status of a configured grant timer, where the DRX of the communications device is in an active state when the uplink retransmission timer works; and monitors a PDCCH when the DRX of the communications device is in the active state.
