Abstract

A data transmission method for a base station to acquire transmission beam diversity in a wireless communication system is provided. The data transmission method includes selecting at least two transmission beams to be used for data transmission from among multiple transmission beams corresponding to transmission beam information, if receiving the transmission beam information regarding the multiple transmission beams from a terminal, and transmitting data encoded with a predetermined orthogonalization code to the terminal via the selected at least two transmission beams.

Description

technical field [0001] The present invention relates to wireless communication systems. More particularly, the present invention relates to a beamforming method and apparatus for obtaining transmission beam diversity in a wireless communication system. Background technique [0002] In order to meet the ever-increasing demand for wireless data traffic, wireless communication systems have evolved to support higher data rates. The recently commercialized 4th generation (4G) communication systems were mainly developed to improve spectral efficiency to increase data rates. However, it is difficult to meet the explosive growth of wireless data traffic demand only by improving the spectrum efficiency. [0003] Therefore, in order to meet the demand for wireless data traffic which has exploded recently, research into the use of a wide frequency band has been actively conducted. Currently, the frequency bands used in mobile communication cellular systems are generally lower than 1...
