    Abstract: 5G, New Radio (NR), numerology, receiver issues. The numerology scheme here consists in keeping the bandwidth constant but varying the subcarrier spacing (ie different tone spacing B for data and K*B for control channels), and correspondingly the symbol duration. Control symbols have a wider subcarrier separation but smaller symbol duration (In the case of beamforming reference signals, it would enable to train K beams in one symbol time period). Receiver issues: Embodiment 1 uses different Rx chains for data and control channels with different FFT sizes (size differing by factor K). Embodiment 2 uses a common identical FFT size (the one of the data channel) for both control and data: For the control channel, either repeat each control symbol K times prior to FFT and performs down-sampling afterwards and repeat it for each control symbol, or performs joint processing and FFT for all K control symbols jointly by either time domain linear combination or post FFT frequency processing.

    Abstract: Systems, methods, apparatuses, and computer program products for machine learning based channel state information (CSI) estimation and feedback configuration are provided. A method may include learning channel state information feedback from one or more user equipment as time series data. The method may also include building a predictive model for user equipment feedback based on the learned channel state information feedback. The method may further include configuring a channel state information trigger with the one or more user equipment based on the predictive model. In addition, the method may include signaling predicted channel state information to the one or more user equipment.
