The invention provides an emission antenna selection diversity method, a system and a mobile terminal. The method comprises steps of using a radiation direction controllable antenna as an emission antenna, wherein the radiation direction controllable antenna carries at least two preset radiation directions; selecting emission states of the two radiation directions of the radiation direction controllable antenna to serve as a main emission antenna mode and an auxiliary emission antenna mode; according to the selection diversity mode of the emission antenna, allowing the radiation direction controllable antenna to be switched to be emitted between the main emission antenna mode and the auxiliary emission antenna mode. According to the invention, an antenna emission selection circuit with big power is not required; cost of a power amplification module of the emission antenna is reduced; power consumption and cost can be obviously reduced; the function of double antenna emission diversity is achieved; and realization difficulty level of a terminal system is reduced.
Description
technical field [0001] The present invention relates to the field of antennas, in particular to a transmit antenna selection diversity method, system and mobile terminal. Background technique [0002] Currently, mobile terminals need to support transmit antenna selection diversity. The transmit antenna selection scheme includes open-loop antenna selection and closed-loop antenna selection. Open-loop antenna selection scheme: the uplink shared data channel is transmitted alternately between antennas, so as to obtain space diversity gain and avoid deep sinking of the shared data channel. It is recommended to use open-loop antenna selection in suburban, rural, highway, subway, high-speed rail and other places. Closed-loop antenna selection scheme: the terminal must send reference signals from different antennas for channel quality measurement in advance on the base station side. The base station may select an antenna with higher transmit signal power for subsequent transmiss...
