1. A method for operating a user equipment (UE), the method comprising:
receiving, by the UE, at least one indicator from a first network controller, the at least one indicator specifying at least one parameter associated with cell-specific reference signal (CRS) symbols transmitted by a second network controller; and
receiving, by the UE, a physical downlink shared channel (PDSCH) from the first network controller, the UE assuming that resource elements corresponding to the CRS symbols transmitting by the second network controller are not available for carrying the PDSCH received from the first network controller.
