Abstract: A method for performing wireless communication by a first device includes: receiving information related to a time division duplex (TDD) slot configuration, transmitting, to a second device, a sidelink-synchronization signal block (S-SSB), the S-SSB including a sidelink primary synchronization signal, a sidelink secondary synchronization signal, and a physical sidelink broadcast channel, and transmitting, to the second device, a physical sidelink shared channel based on the information related to the TDD slot configuration. Candidate resources to which a bitmap related to a sidelink resource pool is applied (i) are configured based on the information related to the TDD slot configuration and (ii) include one or more slots. Configuration information related to a sidelink symbol included in each of the one or more slots is received, the configuration information including information related to a position of the sidelink symbol configured to be the same for the candidate resources.

Abstract: A method of a first user equipment (UE) for transmitting inter-UE coordination information in a wireless communication system is disclosed. The method includes receiving a request for inter-UE coordination information from a second UE, and transmitting inter-UE coordination information to the second UE. The request is received based on a presence of data transmitted by the second UE. Based on that the second UE has first data to be transmitted to the first UE, the request is received based on a medium access control-control element (MAC-CE) and/or second sidelink control information (SCI).
