  • Patent number: 10879610
    Abstract: This application discloses an antenna apparatus, including an antenna array and an adjustable phase shifter. In each row of antenna elements in the antenna array, antenna elements on a same radio frequency RF channel are spaced by M antenna elements, where M is used to determine a quantity of beams in a first beam group and a quantity of beams in a second beam group, and M is an integer greater than 1. When the adjustable phase shifter is at a first angle, the first beam group is obtained; or when the adjustable phase shifter is at a second angle, the second beam group is obtained. This application discloses a beam adjustment method. In this application, a plurality of beams can be formed in a horizontal direction, and the beams are grouped by using an adjustable phase shifter, thereby effectively improving beam adjustment flexibility.

    Abstract: An antenna system and a signal transmission method are provided. The antenna system includes: an antenna array and a matching network, where an S parameter matrix of the matching network matches an S parameter matrix of the antenna array and the matching network is configured to perform pre-distortion on a to-be-transmitted signal or de-distortion on a received signal, and the antenna array is configured to transmit the pre-distorted to-be-transmitted signal. According to the antenna system and the signal transmission method provided in this application, pre-distortion may be performed on a signal that needs to be transmitted by the antenna array or de-distortion may be performed on a signal received by the antenna array, so as to configure energy that is coupled from each antenna array element to an adjacent antenna array element, thereby reducing a coupling effect between antenna array elements.

  • Patent number: 10743195
    Abstract: According to a communication method and a base station that are provided in embodiments of the present invention, the base station transmits a broad beam that covers a sector of the base station and narrow beams whose coverage areas completely fall within a coverage area of the broad beam, which implements that under a premise that a coverage area of the sector of the base station maintains unchanged by using the broad beam, enhanced coverage of the sector is further achieved by using the narrow beams, thereby improving spectral efficiency. In the solutions, a sector coverage area of the broad beam transmitted by the base station still maintains unchanged, and therefore, a coverage relationship between sectors is not affected. In addition, neither an additional site backhaul resource nor additional standardization support is required in the solutions.

  • Patent number: 10236962
    Abstract: A method includes: a transmit end transmits at least two mixed pilot signals to a receive end separately by using at least two physical antennas. The at least two mixed pilot signals are separately obtained after preset pilot signals corresponding to logical antennas in the at least two logical antennas are weighted by using a precoding weight matrix. The transmit sends a first codebook subset restriction instruction to the receive end. The first codebook subset restriction instruction carries a rank indication RANK and at least one precoding matrix index PMI. The transmit end receives a channel quality feedback message that is fed back by the receive end according to downlink channel quality of an equivalent channel of a specified antenna. Accordingly, a suitable serving antenna is selected for a receive end, thereby improving signal quality.
