Problems solved by technology

[0003] However, radio communication signals have a characteristic of increased signal attenuation, and in ultra-high frequencies of 28 GHz or higher, the degree of signal attenuation is very large and thus significantly limits the cell size and service area

Abstract

A multicell access method using beamforming in a wireless communication system is provided. In the method for operating a terminal, an access procedure for accessing a first base station using a first antenna and accessing a second base station using a second antenna is performed. Communication with the first base station is performed using the first antenna. Communication with the second base station is performed using the second antenna.

Description

technical field [0001] The present disclosure relates to a communication technique using beamforming in a wireless communication system. Background technique [0002] In recent years, with the rapid distribution of wireless Internet communication devices including smart phones, mobile communication data demand has rapidly increased at an average annual rate of about 50% to 200%. To meet this rapidly increasing data demand for mobile communications, various data transmission rate improvement technologies are being developed. One of the various ways to increase the data transfer rate is to use wider frequency bands. However, it is difficult to secure a wider frequency band in the current frequency band used for mobile communication systems. On the contrary, in the case of a frequency band of 28 GHz, 38 GHz or higher, the frequency use frequency is low so that a wide frequency band of several hundred MHz to several GHz can be easily secured. [0003] However, radio communica...
