Abstract

The embodiment of the invention provides communication methods and equipment. A method comprises the following steps that network equipment determines to trigger aperiodic beam scanning for terminal equipment; first downlink control information carrying scanning indication information to the terminal equipment, wherein the scanning indication information is used for triggering the terminal equipment to carry out aperiodic beam scanning; and the terminal equipment receives the first downlink control information carrying the scanning indication information from the network equipment and carriesout the aperiodic beam scanning according to the scanning indication information. According to the embodiment of the invention, the aperiodic beam scanning can be triggered rapidly, and beam management efficiency is improved.

Description

Technical field [0001] The embodiments of the present application relate to the field of communication technology, and in particular to a communication method and device. Background technique [0002] Beamforming is a signal preprocessing technology based on antenna arrays. Beamforming generates directional beams by adjusting the weighting coefficient of each element in the antenna array, thereby obtaining significant antenna array gain. Generally, the narrower the beam, the greater the signal gain. But at the same time, once the direction of the beam deviates from the user, the user cannot receive high-quality wireless signals. In order to ensure the gain of the antenna array, the beam on the base station side and the beam on the user side need to be aligned to ensure cell coverage and link quality. Especially for narrow beamforming technology, the selection error of the beam direction will cause the signal to interference plus noise ratio (SINR) to be significantly reduced. ...
