Abstract

The embodiment of the invention discloses an antenna device and related equipment. The antenna device can comprise an antenna array and a control unit. The control unit is used for determining a firstantenna subarray from N rows multiplied by M columns of radiation units of the antenna array. The first antenna subarray comprises X1 rows multiplied by Y1 columns of radiation units, and X1 is greater than Y1. The phase shift increment change of the first antenna subarray is controlled to generate a plurality of first beams. A first alignment beam is determined from multiple first beams based onthe feedback from a receiving end. The control unit is further used for determining a second antenna subarray from the N rows multiplied by M columns of radiation units. The second antenna subarray comprises X2 rows multiplied by Y2 columns of radiation units, and Y2 is greater than X2. The phase shift increment change of the second antenna subarray is changed to generate multiple second beams. Asecond alignment beam is determined from a plurality of second beams based on the feedback from the receiving end. The efficiency of beam alignment can be enhanced by using the antenna device.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an antenna device and related equipment. Background technique [0002] Due to the high frequency and high gain, the large antenna array can overcome the path loss of multipath transmission and meet the requirements of backhaul and mobile scenarios in 5G communication. The more array elements in a large array, the narrower the beam width, the more challenging the beam alignment within the specified scan range, and the longer the beam scan and beam alignment time. [0003] In array beam alignment, the coverage of a single beam is small, and the beam scanning method is required to continuously switch between beams. For long-distance point-to-point communication (PTP), the beam alignment of the transceiver antenna needs to complete the process of sector scanning (Sector Level Sweep, SLS), and both ends of the transceiver need to perform a beam scan. The antenn...
