Title:
METHOD AND DEVICE FOR SIGNALING INFORMATION RELATED TO TDD SLOT CONFIGURATION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/075829
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication is presented. The method can comprise the steps of: receiving information related to a time division duplex (TDD) slot configuration; transmitting a sidelink-synchronization signal block (S-SSB) to a second device, the S-SSB including a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH); and transmitting a physical sidelink shared channel (PSSCH) to the second device on the basis of the information related to the TDD slot configuration. For example: a candidate resource, to which a bitmap related to a sidelink resource pool is to be applied, can be configured on the basis of the information related to the TDD slot configuration; the candidate resource can include one or more slots; configuration information related to a sidelink symbol included in each of the one or more slots can be received; the configuration information related to the sidelink symbol can include information related to the position of the sidelink symbol; and the position of the sidelink symbol can be set to be equal to that of the candidate resource.
