A beam training method and device

Abstract

The embodiment of the invention discloses a beam training method and apparatus. The beam training method comprises: a transmitting terminal simultaneously forms at least two beams and simultaneously transmits different beam training information at the at least two beams; according to a preset range covered by beam training, the transmitting terminal transmits different beam training information again at beams different from the at least two beams respectively and simultaneously until the beam where the transmitted beam training information is located covers the preset range, so that a receiving terminal can determine measurement quantities of the different beams according to training sequences included by the different beam training information; and a target beam is selected and an identifier of the target beam is returned to the transmitting terminal. Therefore, beam training information can be transmitted at the at least two beams simultaneously and thus the beam can cover the preset range quickly, so that time of the beam training process can be shortened.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a beam training method and device. Background technique [0002] With the development of multimedia applications and the improvement of user experience, the demand for wireless communication transmission performance is also increasing, and the use of high-gain directional antenna transmission technology is one of the important solutions. The directional antenna can concentrate energy in a narrow range by sending a directional narrow beam under the condition that the transmission power remains unchanged, thereby increasing the receiving power and improving the transmission performance. [0003] The current beam training method is as follows: the sending end forms a beam each time, and sends beams containing the same training information one by one in each direction to cover the entire range. When the beam sent by the sending end covers the entire range, the receivin...

However, in practice, it is found that the beam training method needs to send many narrow beams to cover the entire range, resulting in a long time-consuming beam training process.
