  • Patent number: 11901986
    Abstract: A method for providing signals for beam-formed transmission comprises retrieving, from a memory, of first vector-associated data defined by an obtained first beam index, assigned to a first signal, scheduled to be transmitted by beamforming in a first direction. The memory has vector-associated data characterizing at least two sets of beamforming vectors for each polarization and for each one of a plurality of beam directions. The beamforming vectors for each polarization and plurality of directions present different tapering and/or non-tapering. The first vector-associated data characterizes a first selected set of beamforming vectors that are designed to give a beam in the first direction. The first beam index comprises information for defining vector-associated data characterizing a particular one of the at least two sets for the first direction. A beamforming of the first signal is initiated by use of the first vector-associated data.

  • Patent number: 11894899
    Abstract: A hybrid beamforming device utilizes analog beamformers (ABF) and digital beamformers (DBF) to produce a desired radio frequency radiation pattern having one or more lobes pointing in particular directions. A set of directions, such as each pointing toward a different candidate area of the sky, are processed to determine a coarse direction. ABF beam coefficients are determined based on the coarse direction. DBF beam coefficients are determined based on the directions in the set of directions, providing more precise directionality in the pattern. The ABF beam coefficients may be sent to the ABFs at a first cadence, such as every second. The DBF beam coefficients may be sent to the DBFs at a second cadence that is faster than the first cadence, such as every millisecond. This facilitates rapid scanning of different precision directions, such as of different portions of the sky to receive a broadcast transmission from a satellite.

  • Patent number: 11881966
    Abstract: Systems, methods, and devices to reduce the channel estimation overhead by collecting data from many UEs and building a location-based mathematical model are disclosed. During building of the model, a reference signal is used to collect location- and signal-related data from connected UEs. Once the model is successfully built, it is then transmitted and/or downloaded to each new UE that connects to the base station. The UEs and/or the base stations then use this model to determine their own transmission parameter values. The UEs also report their location to the base stations, which use the model to estimate channel conditions and adapt transmission parameters for themselves.

  • Patent number: 11863266
    Abstract: A method, an electronic device with a memory configured to store a hierarchical codebook with a processor operably connected to the memory to perform the method, and a non-transitory computer-readable medium storing instructions that when executed by a processor of an electronic device cause the electronic device to perform the method. The method identifies input data including at least one of an array size, an antenna element spacing, a phase-shifter resolution, a specified coverage region, or an antenna element pattern. The input data is processed by putting an initial beam through a non-decreasing concave utility function which uses a cyclic coordinate descent algorithm that generates a wide beam meeting one or more design specifications. A codebook is produced that includes the wide beam.

  • Patent number: 11843486
    Abstract: High-speed communication links with self-aligned scrambling on a communication link that sends scrambled signals may include a slave device that may self-align by initially detecting an unscrambled preamble symbol and more particularly detect an edge of the unscrambled preamble symbol. Based on the detected edge, a fine alignment adjustment may be made by testing subsequent scrambled data for a repeated pattern such as an IDLE symbol by comparing the repeated pattern to a candidate scrambled sequence that has been received through the communication link. The comparison may use an exclusive OR (XOR) circuit on some bits to derive a scrambler seed that is used to test for a match for the remaining bits. If there is a match, the scrambler seed and frame alignment have been detected and alignment is achieved.
