  • Negative electrode particle and preparing method thereof, negative electrode sheet, and energy-storage apparatus
    Patent number: 12080871
    Abstract: A negative electrode particle and a preparing method thereof, a negative electrode sheet, and an energy-storage apparatus are provided. The negative electrode particle provided in the disclosure defines a closed pore located inside the negative electrode particle and an open pore located on a surface of the negative electrode particle. A ratio of a pore volume C1 of the closed pore to a pore volume C2 of the open pore satisfies: 6?C1/C2?11, and the pore volume C1 of the closed pore satisfies: 0.03 cm3/g?C1?0.12 cm3/g.

  • Beam training sequence design method and apparatus
    Patent number: 10951288
    Abstract: The present disclosure relates to beam training sequence design methods and apparatus. One example method includes generating NT beam training sequences, where each beam training sequence includes a cyclic prefix and (2×N) Golay sequences, each Golay sequence is with a length of L, and the NT beam training sequences are orthogonal to each other, and sending the NT beam training sequences using NT transmit antennas, where each transmit antenna of the NT transmit antennas sends one beam training sequence of the NT beam training sequences.

  • Beam training sequence design method and apparatus
    Patent number: 10498420
    Abstract: An example method includes generating, by a transmit end of a transceiver, NT beam training sequences, where each beam training sequence includes a cyclic prefix and a Golay sequence with a length of 2×N×L, and where the NT Golay sequences are orthogonal to each other. The transmit end can then send the NT beam training sequences to a receive end by using the NT transmit antennas at the transmit end, where each transmit antenna sends one corresponding beam training sequence.
