The channel measurement is performed on a first set of reference signal (RS) resources, and the interference measurement is performed on a second set of RS resources. Each of the second set of RS resources is mapped to each of the first set of RS resources. The L1-SINR is determined from a first RS resource of the first set of RS resources and a second RS resource of the send set of RS resources, where the first RS resource is mapped to the second RS resource. A message including the L1-SINR is generated and transmitted to the access node. ## Claims ### Claim 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;
