Abstract

The invention provides a method for adjusting the half-power angle of an antenna. The maximum half-power angle or the maximum beam gain of a single transceiving channel can be adjusted. The method comprises the steps that M antenna arrays needing to be turned on or turned off in N antenna arrays connected with a first receiving and transmitting channel of access network equipment are determined firstly, wherein M is larger than N and larger than or equal to 1, and N and M are integers, that is, the number of the antenna arrays driven by the first receiving and transmitting channel needs to beadjusted; and then first indication information is sent to the access network device, wherein the first indication information is used for indicating to turn on or turn off the M antenna arrays.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and device for adjusting the half-power angle of an antenna. Background technique [0002] Beams are generally defined as selectivity to different directions in space, and can be directed to different directions in space through beamforming. To put it simply, if the multiple antenna elements connected to the transceiver channels are uniformly distributed linear arrays, and the number of such transceiver channels is greater than or equal to 2 and are also arranged linearly, beamforming (beamforming) can be performed by adjusting the phase of the transceiver channels. ), pointing in different directions in space. The range over which a beam can be pointed is generally defined by the half power angle. The half-power angle includes a vertical half-power angle and a horizontal half-power angle, wherein the vertical half-power angle defines the beam width in ...
