Title:
METHOD AND APPARATUS FOR RATE-MATCHING CONTROL INFORMATION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/112575
Kind Code:
A1
Abstract:
A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: attaching cyclic redundancy check (CRC) bits to first bits related to second sidelink control information (SCI), thereby acquiring second bits; acquiring third bits on the basis of channel coding regarding the second bits; acquiring the number of first modulation symbols related to the second SCI on the basis of the number of the first bits, the number of the CRC bits, a beta offset value included in a first SCI related to the second SCI, an alpha value configured with regard to each resource pool, the number of symbols related to physical sidelink shared channel (PSCCH) transmission, and the number of resource elements (REs) related to transmission of the second SCI with regard to each symbol; acquiring the number of second modulation symbols related to the second SCI by adding a gamma value to the number of the first modulation symbols on the basis of the number of at least one RE, to which the first modulation symbols are not mapped, among multiple REs on a symbol, to which the last modulation symbol among the first modulation symbols is mapped, within a resource block (RB) to which the last modulation symbol belongs; and performing rate matching regarding the third bits on the basis of the second modulation symbols.
