Embodiment Construction

[0041] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0042] An embodiment of the present invention provides a beamforming method, which is applied in a dual-beam communication system. The base station in the communication system uses two beams to serve users in a cell, such as figure 1 As shown, the method includes:

[0043] Step 101, acquiring location information of each user to be served by the next time slot service.

[0044] Step 102, according to the obtained location information, select the combination of the total throughput of each user relative to the downtilt angle (β 1 , β 2 ) of the total throughput function β1 and β2 represent the downtilt angles of the first beam and the second beam respectiv

Abstract

The invention provides a method and device for shaping wave beams. The method includes the steps of obtaining position information of users to be served by a current time slot, determining a handling capacity function of the total handling capacity of the users relative to downward inclination angle combinations according to the position information of the users, estimating the downward inclination angle combination by which the maximum value of the handling capacity function is obtained with the DIRECT algorithm, and then adjusting the downward inclination angles of the two wave beams according to the downward inclination angle combination obtained through calculation. By means of the technical scheme, the system hanging capacity can be improved.
