Abstract

The invention provides a propagation environment adjustable and controllable method and device, electronic equipment and a computer readable storage medium, and relates to the technical field of wireless communication. The method comprises the following steps: 1, an RIS is deployed between a multi-antenna base station and a user terminal; the signals emitted by the base station are reflected to the user; specifically, the multi-antenna base station forms a matrix according to a preset digital beam, digital beam forming processing is carried out on the emission signal; a transmitting signal pointing to the RIS is obtained; the RIS carries out analog beam forming processing on the incident signal according to a preset phase; the incident signals are reflected to a plurality of single-antennauser terminals; according to the method disclosed in the embodiment of the invention, the RIS is deployed between the base station and the user; the RIS is used for reflecting the signals sent by thebase station to the user, the propagation environment of the base station signals is changed, the signals generated by the base station can avoid obstacles for transmission, and the propagation environment of the signals is remodeled to be in an ideal state; the problems of signal fading, obstacle shielding and the like are effectively solved; data transmission rates are increased.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device, electronic equipment and computer storage medium with adjustable propagation environment. Background technique [0002] With the continuous development of communication technology, the explosive growth of the number of mobile devices has triggered an urgent need for high-speed and seamless data services in future wireless systems. The propagation environment between the base station and the user antenna is an important factor affecting wireless data transmission. Usually, the propagation environment between the base station and the user antenna is a complex time-varying wireless environment. Therefore, how to communicate in a complex time-varying wireless environment Improving link quality has become an urgent problem to be solved. [0003] Traditional methods for enhancing target signals all rely on additional hardware, which inevitably ...
