Data transmission method, related equipment, and data transmission system

Abstract

The invention discloses a data transmission method, related equipment, and a data transmission system. The data transmission method comprises steps that a receiver is used to receive a plurality of training sequences, which are transmitted by a transmitter via a plurality of training beams, by using fixed beams, and the plurality of training beams are acquired based on the current first data beamsof the transmitter, and the training beams are respectively corresponding to the training sequences; the receiver is used to receive training beam indication information transmitted by the transmitter, and the training beam indication information is used to calculate the deviation information of the first data beams; the receiver is used to calculate the deviation information of the first data beams based on the plurality of training sequences and the training beam indication information; and the receiver is used to transmit the deviation information to the transmitter. According to the invention, system expenses can be reduced, beam adjustment precision can be improved, and data transmission efficiency can be improved.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to a data transmission method, related equipment and system. Background technique [0002] As the demand for network capacity continues to increase, users have higher and higher demands for spectrum resources. However, the spectrum resources of traditional frequency bands are very limited, so higher frequency bands need to be used for communication to obtain rich spectrum resources, such as millimeter wave band communication. In actual communication, because the space loss of the millimeter wave frequency band is greater than that of the low frequency band, the transmission distance under the same transmit power will be smaller than other low frequency bands. Therefore, the millimeter communication system usually uses directional beams to establish communication between the base station and the user equipment. To reduce space loss. [0003] Directional beams in communicatio...

Moreover, the beams used for data transmission can only be selected from the training beams used, which leads to the fact that the beam adjustment accuracy is affected by the design of the training beams, making the data transmission efficiency low
