Channel state reporting for sidelink communications

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

• transmitting, to a second device, signaling indicating a plurality of channel state information report configurations for sidelink communications between the first device and the second device;
• transmitting, to the second device and based at least in part on transmitting the signaling, a request for a channel state information report according to a first channel state information report configuration from the plurality of channel state information report configurations;
• receiving, from the second device and based at least in part on transmitting the request, the channel state information report according to the first channel state information report configuration;
• transmitting, to the second device based at least in part on transmitting the request for the channel state information report according to the first channel state information report configuration and prior to receiving the channel state information report, a second request for a second channel state information report according to a second channel state information report configuration from the plurality of channel state information report configurations, wherein the second channel state information report configuration is different from the first channel state information report configuration;
• and
• receiving, from the second device and based at least in part on transmitting the second request, the second channel state information report according to the second channel state information report configuration.

An apparatus for wireless communication at a first device, 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 signaling indicating a plurality of channel state information report configurations for sidelink communications between the first device and a second device;
• receive, from the second device and based at least in part on receiving the signaling, a request for a channel state information report according to a first channel state information report configuration from the plurality of channel state information report configurations;
• transmit, to the second device and based at least in part on receiving the request, the channel state information report according to the first channel state information report configuration;
• receive, from the second device based at least in part on receiving the request for the channel state information report according to the first channel state information report configuration and prior to transmitting the channel state information report, a second request for a second channel state information report according to a second channel state information report configuration from the plurality of channel state information report configurations, wherein the second channel state information report configuration is different from the first channel state information report configuration;
• and
• transmit, to the second device and based at least in part on receiving the second request, the second channel state information report according to the second channel state information report configuration.
