US 11,601,919 B2 · V2X sidelink channel design

Abstract

Embodiments are presented herein of apparatuses, systems, and methods for performing vehicle-to-everything sidelink communication. A wireless device may receive vehicle-to-everything resource pool configuration information and sidelink control information. A number of resource elements allocated for a vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the resource pool configuration information and the sidelink control information. A transport block size for the vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the number of resource elements allocated for the vehicle-to-everything physical sidelink shared channel. A low density parity check base graph may be selected for the vehicle-to-everything physical sidelink shared channel based at least in part on the determined transport block size.

Dependent claims

An apparatus, comprising:

a processor configured to cause a first wireless device to:
receive a New Radio (NR) vehicle-to-everything (V2X) resource pool configuration information;
receive NR V2X sidelink control information;
determine a number of resource elements allocated for a NR V2X physical sidelink shared channel (PSSCH) based at least in part on the NR V2X resource pool configuration information and the NR V2X sidelink control information;
determine a transport block size (TBS) for the NR V2X PSSCH based at least in part on the number of resource elements allocated for the NR V2X PSSCH;
and
communicate on the NR V2X PSSCH using the determined TBS.

4 more elements

A first wireless device, comprising:

at least one antenna for performing wireless communications;
a radio coupled to the at least one antenna;
and
a processor coupled to the radio;
wherein the first wireless device is configured to:
receive a New Radio (NR) vehicle-to-everything (V2X) resource pool configuration information;
