Abstract

The invention relates to an information sending method and device and a parameter determining method and device. The method comprises the following steps: sending joint indication information througha physical sidelink broadcast channel (PSBCH), wherein the joint indication information is used for joint indication of a period of time division duplex-uplink-downlink (TDD-UL-DL) and Sidelink time domain resources in the period. According to the embodiment of the invention, the joint indication information can be sent through the PSBCH so as to jointly indicate the period of TDD-UL-DL and the SLtime domain resources in the period by utilizing the joint indication information; that is to say, the same indication information is used for indicating both the period of TDD-UL-DL and the SL timedomain resources in the period, so the compression of TDD-UL-DL configuration information is realized, the load of PSBCH is reduced, and the communication efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to an information sending method and device, and a parameter determining method and device. Background technique [0002] In the NR (New Radio, new air interface) V2X (Vehicle-to-everything, Internet of Vehicles) system, TDD-UL-DL (Time Division Duplex-Uplink-Downlink, Time Division Duplex-Uplink-Downlink) However, when configuring TDD-UL-DL in related technologies, more transmission resources are used or multiple configurations are performed, which increases the load of transmission resources and causes waste of resources and time. Contents of the invention [0003] In view of this, the present disclosure proposes a method for sending information, the method is applied to a network element device, and the method includes: [0004] The joint indication information is sent through the physical side link broadcast channel PSBCH, and the joint indication infor...
