With the continuous abundance of mobile applications, the demands of people on the speed, quality and the like of a wireless network are increasingly greater, and the commercial use of 5G technology gradually meets the network demands of people on the wireless network, such as high bandwidth, low time delay and the like. The frequency band adopted by the 5G technology is higher, and compared with the coverage area of the 3G/4G technology, the coverage area of the 5G technology is smaller, so that the beam forming can be used for enhancing the coverage area of the 5G technology. In particular, the beamforming is to enhance network coverage by adjusting the amplitude and phase of multiple antennas, giving specific shape and direction to the antenna radiation pattern, and focusing the wireless signal energy on a narrower beam.

Possibly, the terminal may select the best beam by using an exhaustive search method, so as to complete communication with the base station; however, the efficiency of scanning the beam by the terminal is low, which may affect the 5G network delay, thereby reducing the communication efficiency between the terminal and the base station.

Illustratively, the base station may determine a target area to which the terminal belongs using an angle of arrival (AOA) of the 4G anchor station to confirm an angle of arrival of the signal in the first period. The specific implementation manner of the base station to determine the target area to which the terminal belongs is not limited.
For example, the terminal may determine a target area to which the base station belongs using an angle of arrival (AOA) of the 4G anchor station in the first period. The specific implementation manner of determining the target area to which the base station belongs by the terminal is not limited.
S302: and performing beam scanning on the target area to obtain beam state evaluation information.
In this embodiment of the present application, the beam state evaluation information may be quality information of reference signals of a plurality of beams from the terminal received by the 5G base station, or the beam state evaluation information may be quality information of reference signals of a plurality of beams from the 5G base station received by the terminal. The content included in the beam state evaluation information may also be set according to an actual application scenario, which is not limited in the embodiment of the present application.
S303: and selecting a target beam for communication according to the beam state evaluation information.
In a possible implementation, the terminal may select a target beam for communication with the base station based on the beam state evaluation information. The specific implementation manner of selecting the target beam for communication with the base station by the terminal is not limited in the embodiments of the present application.
In a possible implementation, the base station may select a target beam for communication with the terminal based on the beam state evaluation information. The specific implementation manner of selecting the target beam for communication with the terminal by the base station is not limited in the embodiments of the present application.
In summary, the method is applied to a 5G non-independent Networking (NSA) base station or a 5G NSA terminal, and the angle of arrival of the AOA acknowledgement signal of the 4G anchor station can be utilized in the first period, so that the target area to which the signal belongs further performs beam scanning on the target area to obtain beam state evaluation information, so that a target beam for communication is selected according to the beam state evaluation information, the efficiency of beam scanning is effectively improved, the 5G network delay is reduced, and the communication efficiency is improved.
On the basis of the embodiment corresponding to fig. 3, fig. 4 is a schematic flow chart of a beam scanning method provided in the embodiment of the present application, including the following steps:
S401: and the base station determines a target area to which the terminal belongs by utilizing the arrival angle AOA of the 4G anchor station and the arrival angle of the acknowledgement signal in the first period.
S402: and the base station performs beam scanning on the target area to obtain beam state evaluation information.
In the embodiment of the application, the base station scans the beam of the target area to which the terminal belongs, so as to determine the target beam list in the target area to which the terminal belongs. The target beam list includes a plurality of beams in a preset angle range of the AOA offset towards two sides, the preset angle may be set to 15 °, and the preset angle may also be set according to actual conditions.
Further, in the embodiment of the present application, the base station scans the target beam list one by one in the second period, so as to obtain at least one first beam state information. At least one second period is arranged between two adjacent first periods, and the number of the second periods is related to the state of the terminal, the beam state information and the like. For example, the number of second cycles may be a variable number, or the number of second cycles may be a fixed number.
Optionally, in the embodiment of the present application, when the first analysis result indicates that at least one of the first beam state information does not meet the beam quality requirement, scanning all beams remaining except the target beam list one by one in the third period, to obtain at least one of the second beam state information. For example, the beam quality requirement may be the lowest beam quality of the communication requirements.
In the embodiment of the present application, the first period, the second period, and the third period may be referred to as a beam scanning period. The time length of the beam scanning period can be flexibly set according to practical situations, and the relevant period length in the third generation partnership project (3rd generation partnership project,3GPP) can also be adopted. For example, the time length of the beam scanning period may employ a basic scanning period defined in 3GPP, which is one symbol length.
The beam scanning period may be set to one symbol length or a plurality of symbol lengths, for example. Preferably, the time length of the beam scanning period can be adjusted by the stability of the status information of the beam. For example, when the beam state information is stable, the duration of the beam scanning period (for example, the length of 5 symbols) can be appropriately increased, so as to reduce the number of beam scanning and save the system resource overhead; when the stability of the beam state information is poor, the duration of the beam scanning period (for example, the length of 1 symbol) can be reduced appropriately, so as to increase the number of beam scanning and ensure the communication quality as much as possible. It should be noted that the time length of the beam scanning period should be an integer multiple of the basic scanning period, and the base station or the terminal may increase or decrease the beam scanning period according to the actual situation, which is not limited in the embodiment of the present application.
In this embodiment of the present application, the beam scanning period may include a plurality of first periods, second periods, and third periods, and at least one second period and at most one third period may be disposed between two adjacent first periods. The number of the second period and the third period between two adjacent first periods can be set to be fixed values, and can be properly adjusted according to actual conditions. In this embodiment of the present application, the time length of the first period, the time length of the second period, and the time length of the third period may be set according to an actual application scenario, which is not limited in this embodiment of the present application.

Wherein the number of second and third periods between two adjacent first periods is a fixed value.
Preferably, in the present embodiment, the number of the second periods and the third periods between two adjacent first periods are the same. For example, two second periods are provided between two adjacent first periods in the beam scanning period, or one second period and one third period are provided between two adjacent first periods in the beam scanning period.
S403: the base station selects a target beam for communication with the terminal according to the beam state evaluation information.
In the embodiment of the application, the base station can update the target beam list according to the beam state evaluation information, so that the total times of scanning the terminal beams are reduced.
In a possible implementation manner, the base station obtains a first analysis result by analyzing at least one first beam state information; the base station determines that the first beam is a target beam under the condition that the first analysis result indicates that the first beam meeting the beam quality requirement exists in at least one piece of first beam state information; in this way, the base station can select a target beam for communication with the terminal.
