Problems solved by technology

In this case, if the UE moves at a high speed within 50 meters from the base station, the beam of the smart antenna will not be aligned with the UE, resulting in call drop

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0039] In order to solve the problem that the downlink beam cannot track the user when the UE moves at a high angular frequency, it is expected that the base station can adaptively adjust the downlink beamwidth of the smart antenna according to the angular frequency ω of the UE relative to the base station. When the frequency ω is large, the downlink beam with a wider width is used to send data, and when the angular frequency ω at which the UE moves is smaller, the downlink beam with a narrower width is used to send data. Therefore, the method of the present invention mainly comprises the following steps:

[0040] A. Set more than one downlink beamwidth for the smart antenna of the base station;

[0041] The multiple downlink beamwidths set in this step can be...

Abstract

The invention discloses a self-adjusting method of intelligent antenna beam breadth, which comprises the following steps: A. setting at least one descending beam breadth for base station intelligent antenna; B. affirming moving angle frequency corresponding to base station for user equipment; C. selecting descending beam shape for the descending beam breadth to satisfy the descending beam breadthmore than or equal the product of angle frequency and intelligent antenna beam direction adjusting time gap. The invention guarantees intelligent antenna beam to trace user equipment, when the angle frequency is large.

Description

technical field [0001] The invention relates to the smart antenna technology of the Time Division Duplex-Synchronous Code Division Multiple Access (TD-SCDMA) mobile communication system, in particular to a method for adaptively adjusting the beam width of the smart antenna. Background technique [0002] At present, the smart antenna used by the TD-SCDMA system base station can generate two kinds of beams, one is omnidirectional beam, which is mainly used for downlink pilot or broadcast channel, and this kind of beam does not need to generate directional beam according to the current position of the user ,like figure 1 As shown in a; the other is a directional service beam, which is mainly used for normal service communication with user equipment (UE), such as figure 1 As shown in b. [0003] When the base station uses the above-mentioned smart antenna to communicate with different UEs normally, the base station will generate different service beams for each UE, and these s...
