Abstract: A method includes transmitting, via a transceiver, radar signals for object detection. The method includes determining whether a moving object is detected using received reflections of the radar signals corresponding to a current radar frame. In response to a determination that no moving object is detected using the current radar frame, the method includes determining whether a moving object is detected using received reflections of the radar signals corresponding to multiple radar frames. The method also includes generating a detection result indicating that (i) no moving object is detected using the multiple radar frames or (ii) the moving object is detected using either the current radar frame or the multiple radar frames.

Abstract: A method includes determining one or more delay values and one or more phase shift values for generation of multiple desired frequency-dependent analog beams. The method also includes configuring one or more true-time delay (TTD) elements and one or more phase shifters of a transceiver based on the one or more delay values and the one or more phase shift values, the transceiver having one or more radio-frequency (RF) chains connected to multiple antennas via the one or more TTD elements and the one or more phase shifters. The method also includes operating the transceiver to generate the multiple desired frequency-dependent analog beams.

Abstract: A method includes selecting, by a base station, a partial search set based on one or more previous measurement reports from a user equipment (UE), the partial search set comprising a set of narrow beams that is a subset of an extended search set associated with an extended search. The method also includes performing, by the base station, a beam tracking search that sweeps the partial search set in order to select a next narrow beam. The method further includes communicating with the UE using the selected next narrow beam.

Abstract: Methods, apparatuses, systems, and computer-readable media for a composite beam generation using machine learning. A method includes identifying a narrow beam for a transmission, identifying a composite beam including the narrow beam based on an association between one or more composite beams and one or more narrow beams, identifying one or more beamforming weights for transmitting the composite beam, and transmitting the composite beam using the one or more beamforming weights. The one or more beamforming weights are determined based on machine learning. In some embodiments, the method includes generating a composite beam codebook including information indicating sets of one or more beamforming weights corresponding to composite beam indexes, respectively. The sets of one or more beamforming weights are determined using respective parameters of a machine learning algorithm that are separately updated for coverage regions of composite beams corresponding to the composite beam indexes, respectively.

Abstract: An electronic device and methods for performing beam management (BM) in systems with antenna arrays capable of operating in combined radar and communication modes are disclosed herein. The electronic device comprises a processor and a plurality of antenna elements configured to operate in a first mode, in which the antenna elements are used for communications with beamforming, and a second mode, in which at least two of the antenna elements are used for radar and the remainder are used for the communications. The processor is configured to perform a mode switch on the antenna elements to switch between the first mode and the second mode, determine, after the mode switch, a new beam to use during a first BM cycle, perform, using the new beam, the first BM cycle to obtain signal quality measurements, and perform a second BM cycle using an updated beam based on the signal quality measurements.

Abstract: Methods and apparatuses in a wireless communication system. A base station (BS) includes a transceiver and a processor. The processor is configured to transmit a common beam to at least one user equipment (UE). The processor is also configured to configure the common beam to have a null area in a direction of a satellite earth station, the null area defining a space within a coverage area of the common beam in which a signal from the common beam is suppressed.
