  • Patent number: 10623087
    Abstract: Techniques to reduce scheduling grants to minimize or eliminate the use of control channels, at the expense of flexibility, allow protection of the system from unnecessary retransmissions in case of interference from the primary system. Use of a single grant to allocate a set of resources across all carriers, or communication channels simplifies the system at the cost of retransmission of a grant for all carriers in the case if interference corrupts the transmission of a subset of the carriers. Thus, complementing a single grant embodiment with detection of the affected frequency carriers or victim carriers and remove such carriers from the carrier aggregation configuration allows more efficient use of the allocated spectrum.

  • Patent number: 10524159
    Abstract: In one implementation, congestion in a satellite communications network is managed based on current resource usage information received for a primary satellite servicing a terminal that is requesting to initiate a communications session. The current resource usage information is received within a communications session setup procedure that identifies a type of the communications session being requested by the terminal. Resources for serving the communications session are determined based on the type of the communications session being requested by the terminal. Thereafter, a determination is made as to whether sufficient resources are available at the primary satellite for servicing the communications session. In response to determining that sufficient resources are not available at the primary satellite for servicing the communications session, a congestion mitigation strategy is determined for servicing the communications session and sent to the primary satellite for implementation.

  • Patent number: 10455595
    Abstract: A telecommunication system and a method for generating a real time connection between a first endpoint and a second endpoint in an IP network using an ICE STUN connectivity check follow a procedure that includes the steps of generating a list of possible connection paths between the first endpoint and the second endpoint, establishing a respective priority for each possible connection path included in the list, and generating the real time connection between the first endpoint and the second endpoint. During this procedure first there is an attempt to generate the real time connection using the highest-priority connection path. If this is not possible, then the system attempts to establish the real connection using the connection path with the next highest priority, until the real time connection is actually established. Furthermore, for each possible connection path, its respective quality-of-service value is determined and is considered when establishing its priority on the list.

  • Patent number: 10432308
    Abstract: A system described herein includes a ground based gateway subsystem configured to transmit an RF feeder uplink beam to a satellite, and a space based subsystem of the satellite configured to receive the RF feeder uplink beam and produce in dependence thereon an optical ISL beam that is transmitted to another satellite. The ground based gateway subsystem can include a ground based beamformer used to produce the RF feeder uplink beam. The optical ISL beam, produced by the space based subsystem and transmitted to the other satellite, can comprise a wavelength division multiplexed optical signal having RF frequencies within a same specified RF frequency range within which the other satellite is configured to transmit a plurality of RF service downlink beams, thereby eliminating any need for the other satellite to perform any frequency conversions when producing the plurality of RF service downlink beams in dependence on the optical ISL beam.

  • Patent number: 10432276
    Abstract: Beamforming is used in wireless link communication to improve a wireless link through increased channel capacity and diversity by focusing a beam, such as from multiple antennas, in the direction of the receiver. Where the receiver may be capable of measurements relevant to beamforming, more particularly measurements that vary or are otherwise dependent upon changes in beamforming settings, reference to such measurements and corresponding beamforming settings may improve performance. In this Disclosure, a sink device transmits a data stream to a source device, wherein said data stream comprises the position of the sink device. The data stream may further comprise data such as link quality, heading information, or discretized location. The source device stores this data in a memory.

  • Patent number: 10425151
    Abstract: Systems, devices, and methods for satellite communications are disclosed. The devices and methods can be used for communications diversity in a system having multiple radio frequency terminals (RFTs). In a transmit chain, each RFT can be associated with an antenna for the transmission of signals to a satellite. The system can select one or more uplinks for transmission of one or more versions of a transmit signal via associated antennas. The one or more versions can have a piggyback signal associated with and phase locked to a symbol rate of the transmit signal. In a receive chain, phase differences between the piggyback signals can allow adjustment of one or more time delays in the transmit chain to provide improved signal to noise ratio of the received versions of the transmit signal in the receive chain.

  • Patent number: 10404354
    Abstract: Satellite communication methods and payloads are described. An imbalance in uplink and downlink availability may be mitigated through digitizing uplink spectrum, extracting guard band channels, and grouping the guard band channels to create a composite channel. The composite channel is converted to analog and RF up-converted, amplified, and multiplexed with other downlink analog channels before being transmitted to Earth. The guard bands may be from the same band of spectrum or different bands of spectrum, such as C band, Ka band, Ku band, etc. A satellite payload is described with dual output multiplexers having partially overlapping channels and a dual feed configuration. In one downlink implementation, unused regional band spectrum may be dynamically allocated to a spot beam. In one uplink implementation, regional band spectrum may be shared by a spot beam using spatial separation of the regional uplink location from the spot beam coverage area and digital cancellation techniques.
