This application is based on and claims priority under 35 U.S.C. § 119(a) of a Chinese patent application number 202011135909.X, filed on Oct. 21, 2020, in the Chinese Intellectual Property Office, and of a Chinese patent application number 202110536675.8, filed on May 17, 2021, in the Chinese Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety.
The disclosure relates to a field of wireless communication technology. More particularly, the disclosure relates to a communication method, apparatus, electronic device, and computer-readable storage medium.
In order to meet an increasing demand for wireless data communication services since a deployment of 4th generation (4G) communication system, efforts have been made to develop an improved 5th generation (5G) or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called “beyond 4G network” or “post long-term evolution (LTE) system”.
The 5G communication system is considered to be implemented in higher frequency (millimeter (mm) Wave) bands, e.g., 60 gigahertz (GHz) bands, so as to accomplish higher data rates. To decrease propagation loss of the radio waves and increase the transmission distance, the beamforming, massive multiple-input multiple-output (MIMO), Full Dimensional MIMO (FD-MIMO), array antenna, an analog beam forming, large scale antenna techniques are discussed in 5G communication systems.
