  • Patent number: 12143323
    Abstract: Methods and apparatus for increasing channel diversity in a MIMO system, e.g. a massive MIMO system, are described. Some selected sounding reference signal values are applied to control base station transmission for antennas, e.g., randomly or semi-randomly selected antennas, to which they do not actually correspond. The wireless terminal perceives this change as a change in channel conditions, which is subsequently reported in channel status information (CSI) to the base station. This results in increased channel diversity, which is beneficial to the base station scheduler.
