Abstract: In an embodiment method, a first central controller of a wireless system selects a first common reference signal (“CRS”) pattern for muting on a first type of control channel by the first central controller, wherein the first type of control channel is formed with resource elements (“REs”), and selects a second CRS pattern for muting on a first data channel by the first central controller, where the first CRS pattern and the second CRS pattern are separately configured. The central controller identifies a set of subframes including the first type of control channel, where the set of subframes has REs that overlap the first CRS pattern for muting, and mutes the overlapping REs in the first type of control channel when the set of subframes are not multicast broadcast single frequency network subframes, and frequency-division multiplexes the first type of control channel with the first data channel.

Abstract: Radio resources can be allocated in a manner avoiding a zero power problem by selecting one of two reference signals for control channel estimation, and transmitting the selected reference signal in a resource block (RB) or RB pair carrying the control channel. The two reference signals span common resource elements (REs) in the RB or RB pair. Alternatively, a zero power problem can be avoided by assigning modified WALSH codes to the two reference signals, and transmitting the two reference signals in the RB or RB pair carrying the control channel in accordance with their modified WALSH codes. The modified WALSH codes include complex constants having a non-zero phase difference with one another. A control channel can be evenly partitioned in accordance with a checkerboard partitioning technique.
