Abstract: A method and apparatus for prediction-based non-terrestrial network beam configuration and switching are provided. A base station determines a bandwidth part configuration for a user equipment, which includes a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas. The base station configures the user equipment with the bandwidth part configuration and determines a position or movement of the user equipment in a first geographic area corresponding to a first bandwidth part. The base station determines, based on the position or movement, whether a criterion for reconfiguring the bandwidth part configuration is met. In response to determining that the criterion is met, the base station reconfigures the bandwidth part configuration of the user equipment while the user equipment is positioned in the first geographic area. The reconfiguration includes modifying the plurality of bandwidth parts to include a second bandwidth part corresponding to a second geographic area.

Abstract: Systems and methods for communication link adaptation and communication networks involving ground-based user equipment and non-terrestrial stations. A communication is received indicating signal quality of a first signal transmitted during a first transmission period and a plurality of fading losses associated with the first signal are obtained. A first fading loss and a second fading loss associated with the first signal are estimated for a future time, the first fading loss based on application of a first filter, and the second fading loss based on differences determined between the first fading loss and the plurality of fading losses. A signal-to-interference-plus-noise-ratio is calculated and includes at least one of the first fading loss and the second fading loss. A non-terrestrial station transmits, for a second time period, a second signal having settings determined based on the signal-to-interference-plus-noise-ratio.

Abstract: Various systems and methods for scheduling data transmissions from a base station to user equipment (UE) are presented. Channel quality indicator values that correspond to multiple UE may be determined for multiple carrier components of a cellular network's carrier aggregation. A scheduling matrix may be created that includes instantaneous data transfer rates for the UE. Elements within the scheduling matrix may be normalized by modifying instantaneous data transmission rates using average data transmission rates. Scheduling decisions for data transfers may be made for the UE based on the normalized scheduling matrix.

Abstract: A method and apparatus for non-terrestrial network beam switching is provided. A non-terrestrial network base station includes a transmitter configured to transmit downlink data to user equipment and a receiver configured to receive uplink data from the user equipment. A channel bandwidth of the non-terrestrial network base station is divided into a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas, and each bandwidth part is respectively associated with a satellite beam. When the user equipment is located in a first geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding first bandwidth part. After the user equipment transitions from the first geographic area to a second geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding second bandwidth part of the plurality of bandwidth parts.

Abstract: Embodiments are directed towards systems and methods for selecting, in a Fifth Generation (5G) cellular telecommunication network, a User Plane Function (UPF) of a plurality of UPFs on which to anchor a Protocol Data Unit (PDU) session of a new user equipment (UE) newly appearing on the cellular telecommunication network. The selection is based on: a location of the new UE; a plurality of current loads for each UPF of the plurality of UPFs; a predicted UE load of the new UE based on network data analytics; and predicted UPF loads of the plurality of UPFs as a function of time considering the predicted UE load based on network data analytics from the Network Data Analytics Function. In the UPF selection, the Session Management Function (SMF) gives higher priority to shorter term predicted loads than longer term predicted loads. Also, in the UPF selection, the PDU session of the UE is preferred to attach on the UPF in the current serving area in which the UE is located.
