  • Patent number: 10476627
    Abstract: In a transmission scheme wherein multi-slot packet transmissions to a remote station can be terminated by an acknowledgment signal from the remote station, code symbols can be efficiently packed over the multi-slot packet so that the remote station can easily decode the data payload of the multi-slot packet by decoding only a portion of the multi-slot packet. Hence, the remote station can signal for the early termination of the multi-slot packet transmission, which thereby increases the data throughput of the system.

  • Patent number: 10454569
    Abstract: A communication satellite system provides for spectral efficient data transmissions by a gateway to multiple user terminals by way of a satellite. The gateway transmits multiple blocks in a single slot, each block intended for one of the user terminals, where each block is encoded and modulated according to a scheme that may be different for each intended user terminal. Upon re-transmission of a block if that block is lost or received in error, the block may be encoded and modulated according to another scheme that is less spectrally efficient than in the first transmission of the block.

  • Publication number: 20190305882
    Abstract: Methods, systems, and devices for wireless communications are described. Efficient low-density parity-check (LDPC) scheduling of layered decoding may include receiving a message encoded as an LDPC code that includes a number of check nodes and a number of bit nodes, applying a first number of decoding iterations to decoding the message, applying a second number of decoding iterations to decoding the message after the first number of decoding iterations are applied, and decoding the message through completion of both the first number of decoding iterations and the second number of decoding iterations. In some cases, only a portion of the number of check nodes is decoded during each of the first number of decoding iterations and all of the number of check nodes are decoded during each of the second number of decoding iterations.

  • Patent number: 9955476
    Abstract: Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a “known” transmission (or “reference transmission”) at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference transmission to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need for a location-based service.

  • Patent number: 9730227
    Abstract: A method and apparatus for operating one or more satellites in a non-geosynchronous orbit (NGSO) satellite constellation are disclosed. In some aspects, the satellite may allocate a first frequency band to a first beam, and may allocate a second frequency band to a second beam. Then, if the first beam is disabled, the satellite may re-map the first frequency band from the first beam to the second beam. In this manner, frequency resources initially allocated to a disabled beam may be re-mapping to another, non-disabled beam.

  • Publication number: 20170027017
    Abstract: Power consumption by a communication satellite may be reduced by operating in a transmission time interval (TTI) gating mode, in which an on period is provided for the satellite to transmit a reference signal (RS), control signals, and a portion of data within an on period through a forward link to a user terminal (UT), followed by an off period in which forward link transmission ceases. During the off period of the TTI, the satellite may turn off its forward link power amplifier and cease transmission of data to the UT. A gateway may send a signal enabling the TTI gating mode, as well as information specifying the TTI gating configuration, such as the length of the on or off period of the TTI, to the satellite.

  • Publication number: 20170019814
    Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.

  • Publication number: 20170005741
    Abstract: Methods and apparatus for efficient transmission of data by half-duplex transceivers in satellite communication systems are provided. Time reference for the return link is skewed or time-lagged relative to the time reference for the forward link to reduce the amount of guard time required to separate return link transmission from forward link reception by the half-duplex transceiver of a user terminal. The guard time is determined based on a maximum differential round-trip propagation delay and transition times of the half-duplexer transceiver to switch between transmit and receive modes. In a satellite communication system in which a large number of active user terminals are present in a beam coverage, random time offsets are applied to spread approximately equal traffic loads across the time offsets.

  • Patent number: 9525477
    Abstract: A method and apparatus for estimating a frequency offset of received signals. The receiving device receives a plurality of pilot signals form a transmitting device, and determines an un-aliased frequency offset estimate based on the received pilot signals. The receiving device further determines a low-noise frequency offset estimate based on the received pilot signals, wherein the low-noise frequency offset estimate is blow a threshold noise level. The receiving device then generates a hybrid frequency offset estimate based at least in part on the un-aliased and low-noise frequency offset estimates, wherein the hybrid frequency offset estimate is un-aliased and has a lower estimation noise than the un-aliased frequency offset estimate.
