Abstract

The invention discloses a beam figurative processing method and a device. The beam figurative processing method and the device solve the problem that in the prior art, the call drop rate of a terminal is high. The beam figurative processing method includes obtaining the figurative characteristic value vector, and judging whether the figurative characteristic value vector is right or not. When the figurative characteristic value vector is right, the beam figurative processing device conducts beam figurative operation according to the figurative characteristic value vector. When the figurative characteristic value vector is wrong, the beam figurative processing device conducts beam figurative operation according to the obtained omnibearing figurative coefficient. The call completing rate of the terminal under the state of CELL-dedicated clear channel (DCH) is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a beamforming processing method and device. Background technique [0002] In Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, smart antenna is a key technology. Utilizing the reciprocity of the uplink and downlink channels in Time Division Duplexing (TDD) mode, the base station can use the estimated parameters of the uplink channel for beamforming of the smart antenna. Beamforming can increase base station capacity and extend coverage. When the terminal is connected to the system, the base station performs effective beamforming, which can improve the connection rate. [0003] During the process of the terminal accessing the system, the wireless link on the base station side is established first, and the wireless link on the terminal side is established later. After the wireless link is established on the base statio...
