Problems solved by technology

In an outdoor wireless mobile communication environment characterized by mobility of tens of thousands of kilometers per hour, fast terminal switching, non-line-of-sight (NLOS) path characteristics caused by obstacles, or rapidly changing channel conditions caused by channel fading, the formation of Directional narrow beams, beamforming that maximizes beam gain in specific directions can only increase sensitivity due to performance degradation due to user environment

Abstract

A method for operating a Mobile Station (MS) for uplink (UL) power control in a wireless communication system. The method includes: determining an UL Transmit (Tx) power value compensated for a gain difference value between a downlink (DL) Tx beam and an UL Receive (Rx) beam of a Base Station (BS); and transmitting an UL signal based on the determined UL Tx power value.

Description

technical field [0001] The present disclosure relates to wireless communication systems, and in particular, to wireless communication systems operating based on beamforming. Background technique [0002] To meet the ever-increasing demand for wireless data traffic, wireless communication systems have been developed to support higher data rates. For data rate increases, wireless communication systems have evolved to improve spectral efficiency based on communication techniques such as Orthogonal Frequency Division Multiple Access (OFDMA) and Multiple Input Multiple Output (MIMO). [0003] Recently, an increase in demand for smartphones and tablet computers and an explosive growth in the number of applications requiring a large amount of traffic have accelerated the demand for data traffic. However, the staggering demand for wireless data traffic may not be met by improvements in spectral efficiency alone. Therefore, interest in wireless communication systems using millimete...
