Problems solved by technology

However, because mmWave has short wavelength, high frequency, strong attenuation, and is easily affected by rain attenuation and atmospheric absorption, it cannot guarantee the alignment of the receiving beam and the transmitting beam, and thus cannot obtain the optimal receiving gain and transmitting gain.

Abstract

The embodiment of the invention discloses a beam alignment method and related equipment. Comprising the following steps: receiving a transmitting beam sent by network equipment through a plurality of receiving beams at a current position, and determining a reference signal receiving power (RSRP) of each receiving beam in the plurality of receiving beams; according to the RSRP, selecting an optimal receiving beam from the plurality of receiving beams; according to the optimal receiving beam, determining a rotation angle and a rotation direction required by the terminal equipment for aligning a normal beam with the transmitting beam; and adjusting the position of the terminal device according to the rotation angle and the rotation direction, and forming an optimal beam pair by using the normal beam and the transmitting beam at the adjusted position. By adopting the embodiment of the invention, the transmitting gain or the receiving gain of the terminal equipment can be improved, and the coverage and the mobility of millimeter waves are improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a beam alignment method and related equipment. Background technique [0002] Millimeter wave (mmWave) is one of the most potential technologies to promote the development of fifth generation mobile communication technology (5th generation, 5G). It has the characteristics of large bandwidth and short delay, and the spectrum is cheap, which can reduce costs for operators. Therefore, in the future development of 5G technology, mmWave can not only provide a greater data transmission rate, but also reduce the transmission cost per bit. However, because mmWave has a short wavelength, high frequency, strong attenuation, and is susceptible to rain attenuation and atmospheric absorption, it cannot guarantee the alignment of the receiving beam and the transmitting beam, and thus cannot obtain the optimal receiving gain and transmitting gain.
