Abstract: A method can include determining an initial beam configuration by a controller at a satellite in a non-terrestrial network (NTN); applying the initial beam configuration to control an antenna array to transmit a beam to cover a target service area; determining subsequent beam configurations, by the controller, corresponding to a sequence of locations along an orbit of the satellite; and applying the subsequent beam configurations at each of the sequence of locations successively to control the antenna array to transmit respective beams to cover the target service area while the satellite is flying along the orbit. The controller determines the initial beam configuration and the subsequent beam configurations in a way that a variation of beam footprints of the beams is minimized to realize a constant beam footprint corresponding to the target service area.

Abstract: This disclosure provides a method, an apparatus, and a non-transitory computer-readable medium for radio resource allocation for a terrestrial network (TN) cell. In the method, the TN cell is determined to be outside a coverage of a first non-terrestrial network (NTN) cell. In response to the TN cell being outside the coverage of the first NTN cell, a radio resource is allocated to the TN cell based on a radio resource of the first NTN cell.

Abstract: A method for performing radio resource allocation in a TN-NTN mixed system is provided. The system includes a satellite that covers an NTN cell, and a plurality of TN base stations (TN BSs) within a coverage of the satellite. The NTN cell serves a plurality of NTN user equipments (NTN UEs). The method includes dividing the plurality of NTN UEs into X NTN UE groups; partitioning a radio resource into M parts, where M≥X; dividing the plurality of TN BSs into M TN BS groups; deciding radio resource allocation regarding the plurality of NTN UEs, by allocating an i-th part of the radio resource to an i-th NTN UE group, where i=1, 2, . . . , X; and deciding radio resource allocation regarding the plurality of TN BSs, by allocating a sum of a j-th to an M-th parts of the radio resource to a j-th TN BS group, where j=1, 2, . . . , M.
