Abstract:
1. A method for forming an array antenna beam of a mobile terminal, comprising: comparing direction information of a first beam set toward a maximum signal receiving direction with direction information of a second beam set using position information of a base station and a mobile terminal; and selecting one of the first beam direction information or second beam direction information based on a result of the comparison, wherein the first beam direction information and the second beam direction information are different, wherein the mobile terminal includes an Omni directional antenna in addition to an array antenna, the Omni directional antenna, located at a predetermined location on the mobile terminal relative to the array antenna, and wherein the first beam direction information is determined by: determining a transmit/receive characteristic of a beam of the Omni directional antenna, comparing the transmit/receive characteristics of the array antenna and Omni directional antenna beams; and setting the first beam directional information based on a result of the comparison of the transmit/receive characteristics of the array antenna and Omni directional antenna beams.
