Abstract
Various embodiments herein provide techniques for transport block size (TBS) determination for communication on a physical sidelink shared channel (PSSCH). The embodiments may be used by vehicle-to-everything (V2X) user equipments (UEs). Other embodiments may be described and claimed.
Claims14
One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a user equipment (UE) to:
- determine a transport block size (TBS) for a physical sidelink shared channel (PSSCH) based on an overhead value per physical resource block (PRB) and, for respective symbols that are allocated for a PSSCH transmission:
- a scheduled bandwidth of the PSSCH transmission;
- a number of subcarriers in the respective symbol that carry a demodulation reference signal (DMRS);
- and
- a number of subcarriers in the respective symbol that carry a phase-tracking reference signal (PT-RS);
- and
- encode a PSSCH message for transmission based on the determined TBS.
4 more elements
An apparatus to be implemented in a user equipment (UE), the apparatus comprising:
- a radio frequency (RF) interface;
- and
- processing circuitry coupled to the RF interface, the processing circuitry to:
- determine a transport block size (TBS) for a physical sidelink shared channel (PSSCH) based on an overhead value per physical resource block (PRB) and, for respective symbols that are allocated for a PSSCH transmission:
- a scheduled bandwidth of the PSSCH transmission;
- a number of subcarriers in the respective symbol that carry a demodulation reference signal (DMRS);
- and
- a number of subcarriers in the respective symbol that carry a phase-tracking reference signal (PT-RS);
- and
- encode, based on the determined TBS, a PSSCH message for transmission via the RF interface.
