COMPUTATION OF CHANNEL STATE FEEDBACK IN SYSTEMS USING COMMON REFERENCE SIGNAL INTERFERENCE CANCELLATION Russian patent published in 2014 - IPC H04L1/00 H04B17/00 

FIELD: radio engineering, communication.

SUBSTANCE: when enabled with common reference signal interference cancellation, user equipment (UE) may compute a channel state feedback value taking into account any cancelled interfering neighbouring signals. When neighbouring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value taking into account those cancelled interfering signals. The UE determines whether each neighbouring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighbouring cells or by detecting the transmission schedule, for example based on the power class of the neighbouring cells. If the UE determines that the neighbouring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the cancelled interfering signals.

EFFECT: efficient interference cancellation.
