Abstract: A method, network node and wireless device (WD) for performing adaptive measurement procedures for intermitted and overlapping non-terrestrial network (NTN) coverage are disclosed. According to one aspect, a method in a WD includes determining a satellite coverage time based at least in part on the ephemeris data. The method also includes performing a first measurement procedure to measure satellite signals during a first measurement time when the satellite coverage time is less than a first threshold. The method further includes performing a second measurement procedure to measure satellite signals during a second measurement time when the satellite coverage time is greater than a second threshold.

Abstract: A system and method for integrating 5g and satellite services. A data stream is received from a first network, and traffic conditions in the first network and a plurality of second networks are analyzed. The data stream is segmented into a first portion and at least one second portion based on the analysis of the traffic conditions, and transmitted over the plurality of second networks. The first portion of the data stream and the second portions of the data stream are received at a destination. The first portion of the data stream and the second portions of the data stream are subsequently reassembled, using reassembly information, to reproduce the data stream received from the first network.

Abstract: A system and method for beamforming includes scheduling N data streams of the data streams, selecting a cluster of M feeds from the feeds; computing, with a GBBF processor (ground based beam former), M×N weights; generating M feed excitations by distributing the N data streams per the M×N weights; switching an array to transfer a respective one of the M feed excitations to a respective one of the M feeds; and beamforming, with the M feeds of the antenna, N beams. In the method, the N beams are each focused on a respective service area of each of the N data streams, the M×N weights improve the transmitting into the respective service area of each of the N data streams, and at least one of the N beams includes a portion of a plurality of the M feed excitations.

Abstract: Aspects of the subject disclosure may include, for example, identifying one or more radiating elements of an antenna system that are to be adjusted based on interference determined to affect an operation of the antenna system, and altering one or more properties of the one or more radiating elements to effect polarization adjusting such that an impact of the interference on the antenna system is minimized. Other embodiments are disclosed.

Abstract: Methods, systems, and devices for wireless communications are described. A resource type associated with a transmission to be relayed by a wireless repeater may further be associated with a corresponding likelihood for subsequent forwarding activity (e.g., a corresponding likelihood a base station may send subsequent control information for configuring the wireless repeater to forward additional communications subsequent to the relayed transmission). Therefore, based on a resource type associated with a transmission configured by a wireless repeater configuration from a base station, a wireless repeater may efficiently configure a control interface, and control channel monitoring, subsequent to configured relay operations.

Abstract: Methods, systems, and apparatus, including computer-readable media, for location management for satellite systems. In some implementations, a controller of a satellite network system receives location data from a user terminal and registers the user terminal in a mobility area with a core network. The controller updates a mapping between satellite beams and mobility areas as the satellite beams move along the ground with respect to the mobility areas, then uses the updated mapping to communicate with the user terminal using an appropriate satellite beam. In some implementations, a controller of a satellite network system determines a mapping of satellite beams to mobility areas, and broadcasts, for each of multiple satellite beams, a message indicating (i) a set of mobility areas that are at least partially covered by the satellite beam and (ii) an indication of boundaries of the mobility areas in the set of mobility areas.

Abstract: In particular embodiments, a system may include a spacecraft and optical ground terminals. The spacecraft includes at least an optical space terminal and a space switch unit. The space switch unit is configured to receive physical layer data frames from one optical space terminal, regenerate data-link layer data packets based on the physical layer data frames and route the regenerated data-link layer data packets to another optical space terminal. The optical ground terminals are configured to receive data-link layer data packets by one of the optical ground terminals, encode the received data-link layer data packets into physical layer data frames, transmit encoded physical layer data frames from one of the optical ground terminals to a respective optical space terminal through multiple forward channels at a data rate of 1 Tbps or above, the encoded physical layer data frames are decoded by the respective optical space terminal.

Abstract: An embodiment provides a method for synchronizing a plurality of super frames to a beam switching time plan defining a plurality of dwell times, the beam switching time plan scheduling a switching between at least two beams which are transmitted using a high-altitude platform or a satellite, wherein each beam covers a respective service area so as to forward a respective data frame to the respective service area via the respective beam; wherein each super frame comprises a data frame to be forwarded by the satellite to the respective service area. The method comprises: • transmitting at least a one of the plurality of super frames to the satellite as reference super frame, using a modulator; • applying the beam switching time plan and forwarding - using the satellite - the reference super frame to the reference terminal within a one of the plurality of dwell times; receiving, using a reference terminal, the one of the plurality of dwell times; • determining a known sequence of the reference super frame within the one of the plurality of dwell times; and • determining a time difference between transmitting the reference super frame and receiving the one of the dwell times or receiving of the reference super frame or a time period being directly dependent on the time difference between transmitting the reference super frame and receiving he one of the dwell times or receiving of the reference super frame.
