1. A method for performing wireless communication by a first device, the method comprising:
obtaining a number of resource elements (REs) within one slot based on a number of symbols used for sidelink (SL) within the one slot and a total number of resource blocks (RBs) allocated for physical sidelink shared channel (PSSCH);
determining a total number of REs for transport block size (TBS) determination, by excluding a number of REs for physical sidelink control channel (PSCCH) within the one slot from the number of REs within the one slot;
obtaining intermediate number related to TBS, by multiplying the total number of REs for the TBS determination, a code rate, a modulation order, and a number of layers;
quantizing the intermediate number;
determining the TBS based on the quantized intermediate number; and
performing, to a second device, SL transmission based on the determined TBS.
