Problems solved by technology

The application of narrow beams can combat high-frequency path loss and improve coverage, but a key issue is how to realize the selection and alignment of the base station's transmitting beam and the user's receiving beam through beam scanning, that is, beam matching

Abstract

Embodiments of the invention provide a beam matching method and apparatus. The beam matching method comprises the following steps: determining a beam scanning parameter group; transmitting the beam scanning parameter group to a receiving end device; and scanning a transmitting beam based on the beam scanning parameter group. Another beam matching method comprises the following steps: receiving a beam scanning parameter group from a transmitting end device; and executing beam matching based on the beam scanning parameter group. Corresponding apparatuses are also disclosed. Uniform management ofmultiple beam matching processes can be achieved through a unified beam scanning parameter group, thereby simplifying the beam matching process.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a beam matching method and device. Background technique [0002] Currently, the next-generation evolved system has higher requirements in terms of network performance and user experience, and the fifth-generation mobile communication system (5 th -Generation, 5G) brings greater challenges. Due to its rich spectrum resources, the millimeter wave frequency band has become one of the main working frequency bands of 5G technology. When the millimeter wave frequency band is used, due to the large path loss in the data transmission process of the frequency band, the anti-fading performance is poor, and the coverage is improved by sending narrow beams. The application of narrow beams can counteract the high-frequency path loss and improve coverage, but a key issue is how to realize the selection and alignment of the base station's transmitting beam and the user's rece...
