Problems solved by technology

[0002] In order to ensure the normal progress of the communication process, the user equipment (UE) needs to perform beam alignment with the network side. However, due to factors such as channel fluctuations, sudden blockage of the communication link, and UE rotation, the UE may lose alignment with the beam. will affect system performance
[0003] If beam recovery is not performed or beam recovery fails, the wireless link will fail, resulting in more delay
The success rate of existing beam recovery methods needs to be improved

Embodiment Construction

[0042] As mentioned in the background technology, in order to ensure the normal progress of the communication process, the user terminal needs to perform beam alignment with the network side, but due to factors such as channel fluctuations, sudden blockage of the communication link, UE rotation, etc., the terminal and the beam may lose alignment , will affect system performance. If the beam recovery is not performed or the beam recovery fails, the wireless link will fail, resulting in more delay. However, the success rate of existing beam recovery methods needs to be improved.

[0043]In the embodiment of the present invention, after determining that the signal quality of the specified beam is not suitable for data transmission, the terminal performs beam measurement, determines multiple recommended beams, and reports the beam identifiers of the multiple recommended beams to the network side.

[0044] Thus, the network side can obtain beam identifiers of multiple recommended ...

Abstract

The invention provides a beam recovery method and device, and the method comprises the steps: determining that the signal quality of a specified beam is out of a range required by data transmission, wherein the specified beam is a beam which is specified by a network side and is used for data transmission; performing beam measurement to determine a plurality of recommended beams, wherein the recommended beams are beams of which the signal quality is within a preset range; and reporting the beam identifiers of the plurality of recommended beams to the network side, so that the network side changes the specified beam into the recommended beam. The method and the device can improve the success rate of beam recovery.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a beam restoration method and device. Background technique [0002] In order to ensure the normal progress of the communication process, the user equipment (UE) needs to perform beam alignment with the network side. However, due to factors such as channel fluctuations, sudden blockage of communication links, and UE rotation, the UE may lose alignment with the beam. Will affect system performance. [0003] If the beam recovery is not performed or the beam recovery fails, the wireless link will fail, resulting in more delay. The success rate of existing beam recovery methods needs to be improved. Contents of the invention [0004] The technical problem solved by the invention is to improve the success rate of beam restoration. [0005] In order to solve the above technical problems, an embodiment of the present invention provides a beam recovery method, including: determi...
