Abstract:
1. A method for operating a wireless system, the method comprising: selecting, by a first central controller, a first common reference signal (“CRS”) pattern for muting on a first type of control channel by the first central controller, the first type of control channel formed with resource elements (“REs”); selecting, by the first central controller, a second CRS pattern for muting on a first data channel by the first central controller, wherein the first CRS pattern and the second CRS pattern are separately configured; identifying, by the first central controller for a first set of user equipments (“UEs”) in a serving area of the first central controller, a set of subframes including the first type of control channel, the set of subframes having REs that overlap the CRS pattern for muting; muting the overlapping REs in the first type of control channel when the set of subframes are not multicast broadcast single frequency network (MBSFN) subframes; frequency-division multiplexing the first type of control channel with the first data channel; and transmitting, by the first central controller to the first set of UEs, the first type of control channel with the muted REs on the identified set of subframes.
