1. A method for performing wireless communication by a first device, the method comprising:
transmitting, to a second device through a physical sidelink control channel (PSCCH), a first sidelink control information (SCI) including scheduling information for a physical sidelink shared channel (PSSCH), information for a physical sidelink feedback channel (PSFCH) overhead, and a beta offset; and
transmitting, to the second device through the PSSCH, a second SCI and data,
wherein a transport block size (TBS) of the data is determined based on a total number of resource elements (REs) allocated for the PSSCH,
wherein the total number of REs allocated for the PSSCH is determined based on a number of REs allocated for the PSSCH within a physical resource block (PRB), and a total number of allocated PRBs for the PSSCH,
wherein the number of REs allocated for the PSSCH within the PRB is determined based on the PSFCH overhead informed by the first SCI, and
wherein a number of REs for transmission of the second SCI is determined based on i) a number of symbols of the PSSCH derived from the PSFCH overhead informed by the first SCI, and ii) the beta offset.
