Layer one sidelink channel state information reporting

A method for wireless communication at a network device, comprising:

• transmitting, to a first user equipment (UE), control signaling comprising an indication of a Uu format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE;
• receiving, based at least in part on the Uu format, a layer one uplink control message from the first UE indicating the channel state information report and an identifier of the second UE;
• and
• determining the channel state information for the sidelink channel between the first UE and the second UE based at least in part on the channel state information report.

An apparatus for wireless communication at a first user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive control signaling comprising an indication of a Uu format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE;
• determine the channel state information for the sidelink channel between the first UE and the second UE;
• configure a layer one uplink control message to indicate the channel state information report according to the Uu format;
• and
• transmit, based at least in part on the Uu format, the layer one uplink control message to a base station indicating the channel state information report and an identifier of the second UE.
