Abstract

The invention provides a configuration information indication method and device, is suitable for the fields of Vehicles to everything V2X, intelligent networked vehicles, aided driving, intelligent driving and the like, is used for solving the problem that SL transmission causes interference on DL transmission in the prior art, and can effectively save signaling overhead. The method is applied to first terminal equipment, and comprises the following steps: receiving uplink and downlink time division duplex (TDD) configuration sent by network equipment; according to the uplink and downlink TDD configuration, sending indication information to second terminal equipment, wherein the indication information is carried in a physical layer sidelink broadcast channel PSBCH of a sidelink synchronization signal block S-SSB, and the indication information is used for indicating period information contained in the uplink and downlink TDD configuration.

Description

[0001] This application is a divisional application of the patent application with application number 202080003448.2 titled "A Method and Device for Indicating Configuration Information". technical field [0002] The present application relates to the field of communication technologies, and in particular to a method and device for indicating configuration information. Background technique [0003] In the fifth generation (5th generation, 5G) mobile communication network new radio (new radio, NR) system, the 5G base station (next generation Node B, gNB) transmits uplink and downlink time division duplex (timedivision duplex, TDD ) configuration, indicating to the UE the time allocation mode of the downlink (downlink, DL) and uplink (uplink, UL) within a certain time range. The UE can receive DL data from the gNB during the DL transmission time, and can send UL data to the gNB during the UL transmission time. [0004] The data transmission of the PC5 interface used for commu...
