Abstract

The invention provides a codebook configuration selection method executed by electronic equipment and electronic equipment. The electronic equipment comprises a plurality of beam levels. The codebook configuration selection method comprises the steps of when a beam level used by the electronic equipment changes from a first beam level to a second beam level in the plurality of beam levels, determining a candidate beam in beams capable of being used by the electronic equipment and a mother codebook of the second beam level; and selecting codebook configuration from the mother codebook of the second beam level according to a detection result of the candidate beam, wherein the mother codebook of the second beam level is obtained by zooming a mother codebook of the first beam level.

Description

Technical field

[0001] The present invention relates to a wireless communication system, and more particularly, to a method for selecting a codebook configuration executed by an electronic device in the wireless communication system and an electronic device that executes the method. Background technique

[0002] In current wireless communication systems such as LTE (Long Term Evolution), a precoding matrix codebook is pre-stored in a wireless base station (BS) and a mobile station (UE), and the codebook is pre-stored in accordance with the channel state of the mobile station. The stored codebook selects the codeword that the mobile station will use to communicate with the wireless base station. In order to be able to quickly and effectively select the codeword that the mobile station will use to communicate with the wireless base station from the pre-stored codebook, in future wireless communication systems such as LTE-Advanced (LTE-A), the successor to LTE, A method has been pr...
