Abstract
Provided are a method for performing sidelink transmission by a first device (100) in a wireless communication system, and a device for supporting same. The method comprises the steps of: determining a transport block size (TBS) on the basis of whether at least one of an automatic gain control (AGC) symbol and a guard period (GP) symbol is used for sidelink transmission; and performing the sidelink transmission with respect to a second device (200) on the basis of the determined TBS, wherein the AGC symbol may be a symbol which a first device (100) uses for AGC, and the GP symbol may be a symbol which the first device (100) uses for TX/RX switching.
Claims20
A method for performing, by a first apparatus, wireless communication, the method comprising:
- determining a number of resource elements (REs) allocated for a physical sidelink shared channel (PSSCH) within one slot and one physical resource block (PRB);
- determining a transport block size (TBS) based on the number of REs;
- and
- based on the TBS, performing sidelink (SL) transmission to a second apparatus,
- wherein the number of REs is determined based on a value obtained by subtracting an overhead value from a value obtained by multiplying 2 subtracted from a number of SL symbols within the one slot with a number of subcarriers within the one PRB.
A first apparatus for performing wireless communication, the first apparatus comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
- determine a number of resource elements (REs) allocated for a physical sidelink shared channel (PSSCH) within one slot and one physical resource block (PRB);
- determine a transport block size (TBS) based on the number of REs;
- and
- based on the TBS, perform sidelink (SL) transmission to a second apparatus,
- wherein the number of REs is determined based on a value obtained by subtracting an overhead value from a value obtained by multiplying 2 subtracted from a number of SL symbols within the one slot with a number of subcarriers within the one PRB.
An apparatus configured to control a first user equipment (UE), the apparatus comprising:
- one or more processors;
- and
- one or more memories operably connected to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- determine a number of resource elements (REs) allocated for a physical sidelink shared channel (PSSCH) within one slot and one physical resource block (PRB);
- determine a transport block size (TBS) based on the number of REs;
- and
- based on the TBS, perform sidelink (SL) transmission to a second UE,
- wherein the number of REs is determined based on a value obtained by subtracting an overhead value from a value obtained by multiplying 2 subtracted from a number of SL symbols within the one slot with a number of subcarriers within the one PRB.
