Abstract

Technology for a user equipment (UE) operable to maintain a plurality of received beams is disclosed. The UE can decode an interference measurement resource (IMR) configuration for the UE that is received from a transmission reception point (TRP). The UE can identify a receive (Rx) beam of the plurality of Rx beams that is associated with the IMR configuration. The UE can perform an interference measurement and a channel measurement using the identified Rx beam. The UE can encode a measurement report for transmission to the TRP, wherein the measurement report is based on the interference measurement and the channel measurement. The UE can have a memory interface configured to send to a memory the IMR configuration.
