Abstract

Embodiments of the present invention relate to a method for transmitting data and a terminal device. The method comprises the steps of: determining, according to first configuration information, that a terminal device performs a first type of transmission at a target transmission resource and, according to second configuration information, performs a second type of transmission at the target transmission resource; determining, according to a first preset rule, that the terminal device determines the first type of transmission or the second type of transmission—where the first type of transmission is a side link transmission performed by the terminal device and another terminal device, and the second type of transmission is an uplink transmission or downlink transmission performed by the terminal device and a network device—as a target transmission type; and performing data transmission by adopting the target transmission type at the target transmission resource. The method for transmitting data and the terminal device of the embodiment of the present invention can reasonably allocate resources when a conflict occurs between side link transmission and uplink/downlink transmission.

Description

Method of transmitting data, terminal device, and computer-readable storage medium The present invention relates to the field of communication, and in particular to a method for transmitting data and a terminal device. The present invention claims priority to a PCT patent application filed with the Chinese Intellectual Property Office on November 1, 2018, with application number PCT/CN2018/113444 and application title “Method for transmitting data and terminal device”, the full contents of which are incorporated herein by reference. The vehicle internet system is a type of sidelink (SL) transmission technology based on Long Term Evolution (LTE) Device to Device (D2D), which differs from the method of receiving or transmitting communication data through base stations in existing LTE systems, and since the vehicle internet system adopts a method of direct communication between terminals, it has higher spectrum efficiency and lower transmission delay. In an NR system, different slot structures are supported in the cell, that is, one or more of downlink symbols, uplink symbols, and flexible symbols may be included within a single slot, and the quantity of various symbols can be configured. Here, a flexible symbol indicates an uncertain transmission direction, but the transmission direction can be changed through other configuration information or downlink control information, and for example, a network device may configure a flexible symbol to use for sidelink transmission, or configure a flexible symbol to use for uplink or downlink transmission. When transport resources are used for both sidelink and uplink transport, determining how to transmit data to those resources is a problem that needs to be solved.
