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 breadth more 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 a smart antenna technology of a time division duplex-synchronous code division multiple access (TD-SCDMA) mobile communication system, and particularly relates to a method for adaptively adjusting the beam width of the smart antenna. Background technique

[0002] At present, the smart antenna used in the base station of the TD-SCDMA system can generate two beams. One is an omnidirectional beam, which is mainly used for downlink pilot or broadcast channels. This kind of beam does not need to generate a directional beam according to the current location of the user. ,Such as 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 Shown in b.

[0003] When the base station uses the above-mentioned smart antennas to communicate with different UEs for normal services, the base station will generate different service beams for each ...
