1. A method, comprising:
receiving, at a user equipment, configuration for one or more interference mitigation patterns indicating which resource elements in a time-frequency resource space should be measured, wherein the configuration further comprises at least one reference signal received power threshold; and
performing interference measurements, by the user equipment using the configuration, based on the one or more interference mitigation patterns,
wherein one or more of the following is performed:
in response to measurement by the user equipment of a serving cell's reference signal received power being below a first threshold, then no cell reference signal-interference mitigation is performed by the user equipment;
in response to an interfering cell's reference signal received power being above a second threshold, then the user equipment reports, via a measurement report to a base station, an indication that the interfering cell's reference signal received power is above the second threshold, for use for the base station to rate match around this long-term evolution cell reference signal via an additional cell reference signal rate-matching pattern; or
in response to an interfering cell's reference signal received power being below a third threshold, then the user equipment performs cell reference signal-interference mitigation.
