Reception of control signaling in presence of interference

A user equipment (UE) comprising:

• a transceiver configured to:
• transmit an indication for one of:
• a first capability to receive physical downlink control channels (PDCCHs) over symbols only when at least one of the symbols does not include resource elements (REs) for a common reference signal (CRS), and
• a second capability to receive PDCCHs over symbols when any of the symbols include REs for the CRS, wherein:
• a PDCCH is according to a new radio (NR) radio access technology (RAT), and
• the CRS is according to a long term evolution (LTE) RAT;
• and
• receive first information for parameters of the CRS;
• and
• a processor operably coupled to the transceiver, the processor configured to determine, based on the parameters of the CRS, the REs for the CRS in symbols of the PDCCH,
• wherein the transceiver is further configured to receive the PDCCH based on the REs for the CRS in symbols of the PDCCH.

A base station comprising:

• a processor configured to determine a first number of antenna ports for a common reference signal (CRS);
• and
• a transceiver operably coupled to the processor, the transceiver configured to transmit:
• first information indicating the first number of antenna ports for the CRS to a first user equipment (UE), and
• second information indicating a second number of antenna ports for the CRS to a second UE, wherein:
• the first number is larger than the second number, and
• the CRS is according to a long term evolution (LTE) RAT.
