Abstract:
A method for wireless communication is provided which includes receiving first and second signals transmitted from first and second antennas, respectively, determining a time offset between the first and second antennas based on the first and second signals, and reporting information regarding the time offset, including information regarding the time offset as being above or below a predetermined threshold. Another method for wireless communication is provided which includes generating channel state information feedback based on an assumption that the time offset is being compensated at a transmitter side. Yet another method for wireless communication is provided which includes receiving information regarding a time offset between multiple transmit antennas, including information regarding the time offset as being above or below a predetermined threshold, and adapting downlink transmissions to account for the time offset.
