SUBCHANNEL SELECTION AND CHANNEL STATE INFORMATION (CSI) INDICATION VIA BUFFER STATUS REPORT (BSR) FOR SIDELINK

Abstract:

Wireless communications systems and methods related to providing subchannel selection or recommendation and/or channel state information (CSI) for sidelink communications (e.g., operating in mode-1 radio resource allocation (RRA) via a buffer status report (BSR) are provided. A first user equipment (UE) transmits, to a base station (BS), a BSR indicating subchannel information associated with one or more UEs. The UE receives, from the BS in response to the BSR report, a grant for transmitting a first sidelink transmission to a second UE of the one or more UEs. The UE transmits, to the second UE based on the grant, the first sidelink transmission.
