1. A user equipment (UE), comprising:
radio front end circuitry configured to receive from an access node (AN) with one or more AN antenna ports, a first set of reference signal (RS) resources and a second set of RS resources over one or more UE antenna ports, wherein RS resources in the first set of RS resources are mapped to RS resources in the second set of RS resources, and wherein the first set and the second set of RS resources are received in a same beam; and
processor circuitry coupled to the radio front end circuitry and configured to:
determine whether a channel state information interference measurement (CSI-IM) or non-zero power channel state information reference signal (NZP CSI-RS) of the second set of RS resources that is quasi co-located (QCLed) with a first RS resource of the first set of RS resources is configured;
when no CSI-IM or NZP CSI-RS of the second set of RS resources is configured to be QCLed with the first RS resource, perform a channel measurement and an interference measurement using the first RS resource;
when a CSI-IM or an NZP CSI-RS of the second of RS resources is configured to be QCLed with the first RS resource, perform a channel measurement using the first RS resource and perform an interference measurement using a second RS resource of the second set of RS resources, wherein the first RS resource is mapped to the second RS resource;
determine, a layer 1 signal-to-interference plus noise ratio (L1-SINR) based on the channel measurement and the interference measurement; and
send a message based at least in part on the L1-SINR to the radio front end circuitry for transmission to the AN.
