Abstract: A method for communication includes receiving in a receiver (70) signals, which include one or more dedicated reference signals (98), that are transmitted from a transmitter (20) over a communication channel in multiple blocks. The signals in each block, including the dedicated reference signals, are transmitted on a respective group of subcarriers over a respective time interval and are precoded using a respective precoding scheme that maps the signals onto multiple antenna ports (52) of the transmitter. Based on the received signals, feedback is computed in the receiver with respect to the communication channel in each of multiple spectral sub-bands, and the feedback for the multiple spectral sub-bands is reported to the transmitter. One or more parameters of the communication channel are estimated jointly over the dedicated reference signals included in each of the spectral sub-bands for which the feedback is reported. The signals are decoded based on the estimated parameters.

First feedback information is calculated relating to first interrelations between the antennas within either the first set or the second set. Second feedback information is calculated relating at least to second interrelations between the first set and the second set of the antennas. The first feedback information is transmitted at a first time/frequency granularity, and the second feedback information is transmitted at a second time/frequency granularity that is finer than the first time/frequency granularity.

Abstract: A method for communication includes receiving in a receiver (70) signals, which include one or more dedicated reference signals (98) and are transmitted from a transmitter (20) over a communication channel in multiple blocks (9OA, 90B). The signals in each block, including the dedicated reference signals, are transmitted on a respective group of subcarriers over a respective time interval and are precoded using a respective precoding scheme that maps the signals onto multiple antenna ports (52) of the transmitter. Two or more of the blocks whose respective precoding schemes differ from one another by no more than a predefined distance are identified. One or more parameters of the communication channel are estimated over the dedicated reference signals included in the identified blocks. The signals are decoded based on the estimated parameters.
