  • Patent number: 11791956
    Abstract: Technologies directed to grant-free transmission communication methodology and systems are described. One method includes determining first data that is associated with data transmission between a communication device and a first user terminal (UT). The method further includes determining, based on the first data, second data. The second data indicates communication resources associated with an uplink to the communication system that is allocated to the first UT. The second data further indicates that the communication resources are available for sending additional data by other non-scheduled UTs. The method further includes sending the second data to the first UT and receiving third data using the communication resources. The method further includes identifying a first portion of the third data that is associated with data transmission by a second UT. The method further includes identifying a second portion of the third data that is associated with data transmission by the first UT.

  • Patent number: 10044478
    Abstract: The present disclosure relates to pseudo-randomization of unused resources at a medium access control layer (MAC) of a user equipment (UE). For example, the disclosure presents a method and an apparatus for determining that an uplink (UL) resource grant, associated with a first radio access technology (RAT), for the UE results in unused resources where there are a greater number of resources than available data for transmission at the UE, wherein the UE is configured to receive information associated with a second RAT, and wherein the first RAT is different from the second RAT, populating the unused resources, at a medium access control (MAC) layer, with pseudo-randomized bits, and transmitting at least a portion of the available data and the populated unused resources using the UL resource grant associated with the first RAT. As such, pseudo-randomization of unused resources at a medium access control layer (MAC) of a UE may be achieved.

  • Patent number: 9304209
    Abstract: Methods and systems for evaluating Global Navigation Satellite System (GNSS) signals are provided. Each of a first GNSS signal received by a GNSS receiver and a second GNSS signal received by the GNSS receiver is accessed. The second GNSS signal can have temporal fluctuations weaker than temporal fluctuations in the first GNSS signal. A delay between a sequence in the first GNSS signal and a corresponding sequence signal in the second GNSS signal is estimated and compared to a threshold. Upon determining that the delay exceeds the threshold, a location is estimated using both the first GNSS signal and the second GNSS signal.

  • Patent number: 9231690
    Abstract: Method, computer program product, and apparatus for signal tracking and decoding in GNSS are disclosed. In one exemplary implementation, a satellite receiver may be configured to receive a first sub-frame of a satellite signal. It defers a determination of validity of the first sub-frame until a preamble of a second sub-frame is received. The satellite receiver receives the preamble of the second sub-frame, and then determines whether there is a data decoding error of the first sub-frame using the first sub-frame and the preamble of the second sub-frame.

  • Publication number: 20110027617
    Abstract: Embodiments of the current invention include methods of forming a strontium titanate (SrTiO3) film using atomic layer deposition (ALD). More particularly, the method includes forming a plurality of titanium oxide (TiO2) unit films using ALD and forming a plurality of strontium oxide (SrO) unit films using ALD. The combined thickness of the TiO2 and SrO unit films is less than approximately 5 angstroms. The TiO2 and SrO units films are then annealed to form a strontium titanate layer.
