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 performing wireless communication by a first device is proposed. The method includes receiving downlink control information (DCI) related to first sidelink from a base station, and transmitting, to the base station, a confirmation message for reception of the DCI related to the first sidelink through a first medium access control (MAC) control element (CE). For example, the first MAC CE may include at least one index information related to at least one semi-persistent scheduling (SPS) configuration activated or released by the DCI.
