US 2021/0243796 A1 · IMPROVED GROUPCAST AND UNICAST IN NEW RADIO VEHICLE-TO-EVERYTHING (V2X) COMMUNICATION

Abstract

Systems, methods, and circuitries are provided for enhancing unicast and groupcast communication in a wireless communication system also utilizing broadcast communication. An example apparatus for a user equipment (UE) wireless communication device, including baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals, and one or more processors is provided. The one or more processors are configured to generate a signal encoding one or more capabilities of the UE wireless communication device and transmit the signal to one or more other UE wireless communication devices.

Claims23

Dependent claims

An apparatus for a user equipment (UE) wireless communication device, comprising baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals, and one or more processors configured to:

generate a scheduling request (SR) or scheduling grant (SG) encoding one or more capabilities of the UE wireless communication device;
and
transmit the signal to one or more other UE wireless communication devices.

An apparatus for a first user equipment (UE) wireless communication device, comprising baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals, and one or more processors configured to:

determine a first set of supported features associated with a first transmit signal;
determine a second set of supported features associated with a second transmit signal;
determine either a broadcast channel access or a unicast channel access for the first transmit signal based on the first set of supported features;
and
determine either a broadcast channel access or a unicast channel access for the second transmit signal based on the second set of supported features.
