    Abstract: A data transmission method and device are disclosed. The data transmission method includes: when a terminal that does not support transmission of data at a first interface and a second interface simultaneously has data transmission requirements simultaneously at the first interface and the second interface, respectively determining highest priority data of each of the first and second interfaces; the terminal compares a priority of the highest priority data of the first interface with a priority of the highest-priority data of the second interface and determines an interface corresponding to higher priority data; and the terminal sends data through the determined interface.

    Abstract: The present disclosure provides a sidelink transmission method and a terminal. The method includes: determining, by a first terminal, that first information is transmitted 1 or N times according to configuration information, wherein N is a positive integer greater than 1; if it is determined that the first information is transmitted N times, transmitting, by the first terminal, the first information to a second terminal N times on a sidelink; if it is determined that the first information is transmitted once, transmitting, by the first terminal, the first information to the second terminal once on the sidelink.

    Abstract: Disclosed are a method for a Buffer Status reporting (BSR), and a terminal, and 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 includes 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.
