Title:
METHOD AND APPARATUS FOR GENERATING PSBCH SCRAMBLING SEQUENCE IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/071205
Kind Code:
A1
Abstract:
A method for performing, by a first apparatus, wireless communication is proposed in an embodiment. The method may comprise a step for generating a plurality of sidelink-synchronization signal blocks (S-SSBs) and transmitting the plurality of S-SSBs to a second apparatus within a preset period. For example, each of the plurality of S-SSBs may include a sidelink primary synchronization signal (S-PSS), sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH). For example, the step for transmitting the plurality of S-SSBs within the preset period may comprise a step for performing scrambling on bit information associated with the PSBCH, modulating the scrambled bit information into a complex signal, and mapping the complex signal onto a physical resource. For example, the scrambling may be performed on the PSBCH included in each of the plurality of S-SSBs on the basis of a same scrambling sequence.
