1. a kind of communication equipment, including:

  • The first antenna unit for polarizing in a first direction;

    In at least 45 degree of the second antenna element of second direction polarization, the first direction and second direction difference;

    First signal processing module, coupled to the first antenna unit;

    Secondary signal processing module, coupled to second antenna element;

    Channel quality determining module, is configured to from reception signal generation CQI, the CQIInclude including snr value and in the transmitting antenna for being configured to the communication equipment be transmitted and the communication equipmentThe rank information with the transmitting antenna with the channel matrix between the reception antenna of equipolarization;

    Antenna mode selecting module, is configured to according to the CQI for being generated in dual polarization operational mode and one poleChange and selected between operational mode,Wherein, based on previously data break during the quality of the pilot signal from the first polarised direction antenna that receives selectingThe dual polarization operational mode or the single polarization operational mode are selected,Wherein, the quality of the pilot signal includes the rank information of the channel matrix;

    Antenna mode indicator signal generation module, is configured to generate the signal for representing selected antenna operational mode;

    AndAntenna mode indicator signal transmission control module, is configured to control the antenna mode indicator signal by aerialThe transmission of chain road direction different communication equipment,Wherein, operational mode is set to into single polarization pattern in each evaluation interval and does not consider the mould in previously data breakFormula is arranged.
