摘要:
In an embodiment method, a central controller of a wireless system selects a common reference signal (“CRS”) pattern for muting on a first type of control channel by the central controller, wherein the first type of control channel is formed with resource elements (“REs”). The central controller identifies, for a set of user equipments (“UEs”) in a serving area of the central controller, a set of subframes including the first type of control channel, wherein the set of subframes has REs that overlap the CRS pattern for muting. The central controller mutes the overlapping REs in the first type of control channel, and frequency-division multiplexes the first type of control channel with data channels. The central controller transmits, to the set of UEs, the first type of control channel with the muted REs on the identified set of subframes.
