Embodiments are directed to a user equipment (UE) that performs 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, selects at least one of the plurality of CCs for tuning away from the MIMO communication in order to perform an inter-frequency (IF) Positioning Reference Signal (PRS) measurement, selects, from among a plurality of receive chains allocated to the selected at least one CC, a subset of receive chains that includes less than all of the plurality of receive chains to be tuned away from the MIMO communication to perform the inter-frequency PRS measurement, and tunes the selected subset of receive chains of the selected at least one CC away from the MIMO communication to perform the inter-frequency PRS measurement.
