摘要： A non-terrestrial network base station transmits to a wireless device access network information indicating an access network type of a plurality of access network types. The wireless device selects based on the received access network type a non-access stratum period from a plurality of periods including a first value and a second value. The non-terrestrial network base station receives from the wireless device a non-access stratum request message and sends the non-access stratum request message to an access and mobility management function.

摘要： A wireless device receives, from a base station, access network information. The wireless device determines, based on the access network information, an access network type. The wireless device selects, based on the access network type, a non-access stratum (NAS) period value from between a first NAS period value associated with a terrestrial network (TN) access network type; and a second NAS period value associated with a geostationary earth orbit (GEO) access network type. The wireless device sends, to an access and mobility management function (AMF), a first NAS request message. The wireless device starts, based on the sending the first NAS request message, a NAS period using the NAS period value.

摘要： A satellite system may have a constellation of communications satellites that provides services to users with electronic devices such as portable electronic devices and home and office equipment. A network operations center may use gateways to communicate with the satellite constellation. The satellite constellation may include sets of satellites with different orbits such as circular orbits with different inclinations, sets of satellites with elliptic orbits, sets of satellites with circular orbits of different altitudes including low earth orbits, medium earth orbits, and/or geosynchronous orbits, and/or sets of satellites with other orbits. The satellite orbits of the satellites in the satellite constellation may be selected to provide coverage to desired user population concentrations at different locations on the earth without using an excessive number of satellites.

摘要： A satellite communications system is disclosed, the system comprising a ground controller, a decode-and-forward (DF) satellite transponder, and a digital high-power amplifier (HPA). The DF is further comprised of a transponder front end including a digital channelizer and a predistorter. The ground controller is configured to transmit multiple-access frequency-division-multiplexed signals to the DF, where the DF is configured to down-convert the signals received at the transponder front end. The digital channelizer is configured to convert the signals received into a single sample steam and feed the stream through the predistorter into the single digital HPA, wherein the HPA is configured to amplify each input sample of the stream in sample-by-sample fashion and generates a discrete output. The DF is further configured to convert the output of the digital HPA to a continuous time signal and up-convert the output with a main carrier frequency for down-link transmission to multiple-access ground users.

摘要： A source terminal, for communications with a destination terminal via satellite links to two clusters of satellites, comprises a transmitter and a multibeam antenna system. The transmitter includes a preprocessor and a bank of modulators. The preprocessor performs a K-muxing transform, which has an inverse transform, on M concurrent input data streams to generate concurrently M output data streams, M>1. Each output data stream is a linear combination of the M concurrent input data streams. The bank of modulators transforms N of the M output data streams into N signal streams, N≤M. The multibeam antenna system transforms the N signal streams into N shaped beams and radiating N1 of the N shaped beams towards the first cluster of satellites and N2 of the N shaped beams towards the second cluster of satellites, where N1 and N2 are positive integers and N1+N2=N.

摘要： A satellite receiver for wireless signals having carrier frequencies in the V or the W band of frequencies is described. The satellite receiver may receive the wireless signals at high elevation angles, such as greater than 62° . This high elevation angle may reduce losses, which may allow the satellite receiver to communicate at a data rate of at least 50 Mbps. In order to accommodate these system requirements, the one or more satellites that provide the wireless signals may have eccentric geosynchronous or near-geosynchronous orbits that are inclined relative to an equatorial plane of the Earth, such as an eccentricity between 0.12 and 0.3. Moreover, the one or more satellites may have ground tracks substantially along one or more continents, and may be in view of dense population regions in the one or more continents with a higher frequency than low-density population regions in the one or more continents.

摘要： A system and method for providing multi-input multi-output (MIMO) feeder links for a multibeam satellite system. The method includes configuring a X×Y MIMO antenna system using X-antennae having dominant line-of-sight (LoS) of Y-antennae; transmitting, simultaneously, a Tx signal as X Tx signals on a MIMO channel with the X-antennae; receiving the X Tx signals on the MIMO channel with the Y-antennae as Y Rx signals, wherein each of the Y-antennae generate one of the Y Rx signals; and ground-interference processing the X Tx signals or the Y Rx signals to recover the Tx signal; satellite-interference processing the X Tx signals or the Y Rx signals to recover the Tx signal. In the method, the ground interference processing includes countermeasures as either pre-interference processing when the X-antennae are disposed on a ground or post-interference processing when the X-antennae are disposed in a Geosynchronous orbit satellite. Gateway diversity for multiple MIMO feeder links utilizing these countermeasures improves weather-resiliency and significantly enhances overall satellite network availability.
