Abstract: The present application provides a method for maintaining a DRX and/or DTX state of a sidelink communication interface and sidelink communication terminals. After a sidelink communication transmitting terminal sends a scheduling request SR or a buffer status reporting BSR corresponding to a sidelink communication interface to a network device, the sidelink communication transmitting terminal updates DRX and/or DTX active time of the sidelink communication interface, and the sidelink communication transmitting terminal is in the DRX and/or DTX active time at the sidelink communication interface within a first preset time period.

Abstract: Embodiments of the present application provide a timing advance (TA) compensation method, a base station, a terminal, and a storage medium. The method includes by means of an interface between network devices, a target base station to which a target cell belongs transmits, to a source base station to which a source cell belongs, TA compensation related information used for a terminal to perform uplink transmission in the target cell. According to the embodiments of the present application, when a terminal performs cell handover, TA compensation related information used for the terminal to perform uplink transmission in a target cell is transmitted to the terminal, and the terminal may clearly and accurately determine a TA pre-compensation value used for the target cell to which the terminal is handed over, and reasonably perform TA compensation, to improve the cell handover success rate of the terminal and reducing handover delay.

Abstract: Disclosed are a method for a Buffer Status reporting (BSR), and a terminal, wherein when both a BSR of a sidelink interface and a BSR of a Uu interface need to be sent by a terminal, the sending of the BSR of the sidelink interface and the BSR of the Uu interface can be dynamically determined, thus ensuring the quality of service of services at the Uu interface and a sidelink interface. The method comprises: a terminal determining a priority order of logical channels on which a Uu interface and a sidelink interface trigger the sending of a Buffer Status reporting (BSR); and the terminal sending the BSR according to the priority order of the logical channels on which the Uu interface and the sidelink interface trigger the sending of the BSR.
