[0020] Please refer to figure 1 , figure 1 It is a flow chart of an antenna beam search method provided in the first embodiment of the present invention, including:

[0021] S101. The base station sends a downlink signal to a terminal to be accessed through an antenna beam;

[0022] S102. The base station receives the signal strength of each downlink signal fed back by the terminal, and uses a service beam meeting a preset condition as a working beam for terminal access.

[0023] An array antenna is an antenna system composed of many identical single antennas arranged according to certain rules, also known as an antenna array, and the independent unit commonly known as an antenna array is called an array element or an antenna unit. According to the arrangement of the array elements, when the array elements are arranged in a straight line, it is called a linear array; when the array elements are arranged in a plane, it is called a planar array. Antennas are widely used in ra...

[0038] Please refer to figure 2 , figure 2 It is a schematic diagram of the composition of an antenna beam search device provided in the second embodiment of the present invention, including:

[0039] A communication module 201, configured to send a downlink signal to a terminal to be accessed through an antenna beam;

[0040] The communication module 201 is also used to: receive the signal strength of each downlink signal fed back by the terminal;

[0041] The control module 202 is configured to use a service beam satisfying a preset condition as a working beam accessed by a terminal.

[0042] Since the physical distance between the terminal and the base station is relatively long, and the distance between the array antennas included in the base station is much smaller than the distance between the terminal and the base station, then the direction of the antenna beam in one array antenna is different from that of other array antennas. The directions of the corresponding ...

[0054] Please refer to image 3 , image 3 It is a flow chart of an antenna beam search method provided in the third embodiment of the present invention, including:

[0055] S301. Judging whether it is the first time to search for the service beam corresponding to the terminal to be accessed, if yes, go to S302; if not, go to S307;

[0056] When the terminal wants to search for a new round of working beams, it can refer to the previous service beams used by the terminal, because the moving speed of the terminal is generally slower than that of the base station, so the movement of the terminal generally does not exceed one Or the coverage of service beams in two adjacent directions. Therefore, by determining the working beam used by the terminal for the last access, the service beam required by the terminal can be located more quickly and the required time can be further shortened. .

[0057] S302, the base station sends T in parallel UE downlink signal;

Abstract

The invention provides an antenna beam search method and device. The method is characterized in that a base station sends downlink signals to a terminal to be assessed through an antenna beam; and thebase station receives signal intensity of each downlink signal fed back by the terminal, and serves service beams that meet preset conditions as work beams for terminal access. According to the method, the downlink signals are sent through the service beams in different directions of different array antennas, thereby avoiding huge time spent in traversing all service beams, greatly reducing timerequired in the search process, reducing service amount required in system processing, improving work efficiency and improving user experience.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an antenna beam search method and device. Background technique [0002] For large-scale array antennas, the purpose is to generate several narrow beams with strong directivity, especially for high-frequency 5G, the high frequency causes the coverage performance of radio waves to be worse than that of low-frequency, and this difference needs to be used Several narrow beams with strong directivity and high beam gain make up for it. [0003] Usually, base stations and terminals need to use several narrow beams for beam coverage, and services need to search, maintain, track and switch beam pairs. The common polling traversal search method consumes too much time, and will bring more losses to the maintenance, tracking and switching of service beam pairs. For example, suppose an array antenna of the base station has M BS beam, an array antenna of the terminal has N UE be...
