The method includes identifying a set of user equipments (UEs) to schedule, a plurality of resource blocks (RBs), and a UE beam map. The UE beam map maps one or more beams from a plurality of beams to one or more UEs in the set of UEs. The method further includes allocating, for a UE in the set of UEs, one or more RBs from the plurality of RBs based the UE beam map and a beam gain on the one or more RBs in a direction of the UE.

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: A method includes identifying child beams of a current composite beam. The method also includes determining an order at which the child beams of the current composite beam are measured based on a likelihood that each child beam of the current composite beam is an optimal beam, among the child beams, to be a serving narrow beam. The method also includes determining a threshold for use in deciding whether to measure one or more additional child beams or select an already measured child beam when selecting the optimal beam. The method also includes selecting the optimal beam, among the child beams, to be the serving narrow beam based on the determined order and the determined threshold.

Abstract: A method, an electronic device with a memory configured to store a hierarchical codebook with a processor operably connected to the memory to perform the method, and a non-transitory computer-readable medium storing instructions that when executed by a processor of an electronic device cause the electronic device to perform the method. The method identifies input data including at least one of an array size, an antenna element spacing, a phase-shifter resolution, a specified coverage region, or an antenna element pattern. The input data is processed by putting an initial beam through a non-decreasing concave utility function which uses a cyclic coordinate descent algorithm that generates a wide beam meeting one or more design specifications. A codebook is produced that includes the wide beam.
