INDICATION OF SINGLE OR MULTI-STAGE SIDELINK CONTROL INFORMATION (SCI)

Abstract:

Certain aspects of the present disclosure provide techniques for wireless communication by a first, transmitting, user equipment (UE) for sidelink communication with a second, receiving, UE. The techniques generally includes determining whether to transmit sidelink control information (SCI) for decoding a physical sidelink shared channel (PSSCH) transmission to a receiving UE in one or multiple stages, transmitting the SCI in accordance with the determination, and transmitting the PSSCH in accordance with the SCI. Release 16 NR sidelink transmissions often include two (or more) stages of SCIs. The present disclosure provides methods and techniques for alternative mechanisms to achieve similar goals as the multiple stages of SCIs when the second (and the subsequent) SCI stage(s) is absent.
