Abstract: Embodiments are directed to a user equipment (UE) configured to perform MIMO communication on a plurality of Component Carriers (CCs) in accordance with a Carrier Aggregation (CA) scheme with each CC having an associated rank number that indicates a respective number of receive chains for the CC, select at least one of the plurality of CCs for tuning away from the MIMO communication in order to perform an inter-frequency Positioning Reference Signal (PRS) measurement based at least in part upon a per-rank throughput contribution by each of the plurality of CCs, a transmission mode of the selected at least one CC and/or a channel quality of the selected at least one CC, and tune a set of receive chains of the selected at least one CC away from the MIMO communication to perform the inter-frequency PRS measurement.
