Abstract

The present application discloses a resource sharing method and a terminal device, including: the first terminal device determines the transmission mode of the second terminal device according to the received PSCCH of the second terminal device; the first terminal device determines the transmission mode of the second terminal device according to the transmission mode of the second terminal device The mode determines the first PSSCH-RSRP threshold; the first terminal device measures the RSRP of the PSSCH corresponding to the PSCCH to obtain the first PSCCH-RSRP; the first terminal device according to the first PSSCH-RSRP and the first PSSCH ‑The size relationship between RSRP thresholds determines the set of available resources that can be used for data transmission. Since the PSCCH-RSRP thresholds determined by the first terminal device according to different transmission modes are different, it is possible to protect the data transmission of terminal devices using different transmission modes in a targeted manner, especially to reduce the impact on terminal devices in the second transmission mode. interference.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, to a resource sharing method and a terminal device. Background technique [0002] The Internet of Vehicles or Vehicle to Everything (V2X) communication system is a sidelink (Sidelink, SL) transmission technology based on D2D communication, which is compatible with the traditional Long Term Evolution (LTE) system through The way the base station receives or sends data is different. The Internet of Vehicles system adopts the method of terminal-to-terminal direct communication, so it has higher spectral efficiency and lower transmission delay. In the version Release-14 (abbreviated as R14) of the 3rd Generation Partnership Project (the 3rdGeneration Partnership Project, 3GPP) protocol, two transmission modes are defined for the Internet of Vehicles, namely mode 3 (mode 3) and mode 4 (mode 4). The terminal device in mode 3 and the terminal device in mode ...
