Method performed by user equipment, and user equipment
According to the present invention, provided is a method performed by user equipment, and the method is characterized by including: obtaining indication information related to resource allocation; and determining N indicated res time/frequency resources according to the indication information, wherein N indicated res is a positive integer greater than or equal to 1, the indication information related to resource allocation includes information indicated in sidelink control information (SCI), and the information indicated in the SCI includes a time resource allocation indication value TRIV and/or a frequency resource allocation indication value FRIV.
1. A user equipment, comprising:
a processor, and
a memory having instructions stored therein, wherein, on the basis of the instructions, the processor is configured to:
receive 1st-stage Sidelink Control Information (SCI) contained in a Physical Sidelink Control Channel (PSCCH), wherein the 1st-stage SCI indicates a time resource indication value (TRIV) and a frequency resource indication value (FRIV); and
determine information on one or more allocated Physical Sidelink Shared Channel (PSSCH) resources, the information including a first starting sub-channel index (f 1 ) for a first resource, as an index of a sub-channel on which a lowest Physical Resource Block (PRB) of the PSCCH is transmitted, wherein
N indicated res is a number of the one or more allocated PSSCH resources indicated in the 1st-stage SCI,
N indicated res is determined based on the TRIV,
if N max res =2, the information includes a second starting sub-channel index (f 2 ) for a second resource, and a number of contiguously allocated sub-channels (m) for each of the one or more allocated PSSCH resources, satisfying:
