Abstract: Embodiments of the present disclosure relate to hybrid beamforming. A plurality of time delay elements is used to perform analog beamforming. Each time delay element is configured to apply the same time delay at different frequencies. The plurality of time delay elements is coupled to at least one RF chain to receive signals. Each antenna in an antenna array is configured to be selectively connected to one of the plurality of time delay elements based on a target configuration of a connection between the plurality of time delay elements and the antenna array. In operation, the target configuration is determined based on time delay information concerning the plurality of time delay elements and channel information concerning a physical channel over which the signals are to be transmitted.
