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: Certain example embodiments provide systems, methods, apparatuses, and computer program products for associating sensing information with a user (e.g., a cellular user) by, for example, determining information from both a sensing node and a communication node, then associating the a sensed object and the communication node based on the information. Additionally, or alternatively, some embodiments provide systems, methods, apparatuses, and computer program products for radar and sensing-based positioning.
