Channel state information (csi) reporting for multicast communications

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

• a processor;
• a memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive, from a base station, a message comprising a multicast downlink grant for a downlink channel associated with a multicast transmission;
• receive, from the base station, a reference signal associated with the downlink channel;
• and
• transmit, to the base station, a unicast message comprising a measurement report indicating a measurement of the reference signal associated with the downlink channel, the reference signal being measured based on receiving the multicast downlink grant.

A method of wireless communication performed by a base station, comprising:

• transmitting, to a user equipment (UE), a message comprising a multicast downlink grant for a downlink channel associated with a multicast transmission;
• transmitting, to the UE, a reference signal associated with the downlink channel, the reference signal being transmitted based on transmitting the message comprising the multicast downlink grant;
• and
• receiving, from the UE, a unicast message comprising a measurement report indicating a measurement of the reference signal.
