Abstract
The embodiment of the present application provides a method and device for wireless communication, which can be used in a beamforming scene. The method comprises the following steps: determining a candidate weight value set from a plurality of candidate weight value sets according to a first analog weight value indicated by first indication information, wherein the first analog weight value is obtained by a baseband unit of a network device according to a downlink channel feature, and the candidate weight value set comprises a candidate weight value related to an antenna preset parameter; and determining a second analog weight value from the candidate weight value set according to a target antenna preset parameter in the antenna preset parameter, wherein the second analog weight value corresponds to a beam used for communication between the terminal device and the network device. The method and device for wireless communication provided by the embodiment of the present application meet the requirement of new services for information that cannot be obtained when estimating the downlink channel feature but affects user experience or network performance, and improve the accuracy of beam weight value calculation.
