Abstract: When enabled with common reference signal interference cancelation, a user equipment (UE) may still compute a channel state feedback value with consideration of any canceled interfering neighboring signals. When the neighboring 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 considering those canceled interfering signals. The UE determines whether each neighboring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighboring cells or by detecting the transmission schedule, such as based on the power class of the neighboring cells. If the UE determines that the neighboring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the canceled interfering signals.

Abstract: A MIMO base station is provided that includes a multi-channel transmitter having an input Fourier Transform Matrix (FTM) and an output FTM that are each coupled to an intervening signal processing section having multiple radio frequency (RF) amplifiers. A signal applied to an input port of the input FTM is distributed to all RF amplifiers of the transmitter by the input FTM and then is recombined by the output FTM such that the signal is routed to a single antenna of the multiple antennas of an antenna array.

The base station further provides antenna selection for a single antenna transmission and gain allocation among the multiple antennas for a MIMO transmission.
