Downlink signals are received through the multiple antennas, a channel state of each antenna is measured, and whether or not each antenna needs to be adjusted or an actual channel measurement value are displayed based on the measured channel state information and an antenna setting mode. Thus, a user can check an antenna with a poor reception performance by using the antenna adjustment information or the actual channel measurement value for antenna adjustment, and easily adjust the direction of the antennas. ## Claims ### Claim 1 An antenna information display method of a mobile terminal, the method comprising: receiving downlink signals through multiple antennas; measuring channel state information of each antenna; and displaying antenna adjustment information based on the measured channel state information and an antenna setting mode. ### Claim 2 (depends on 1) The method of claim 1, wherein the multiple antennas are configured as external antennas or internal antennas of a terminal or a device. ### Claim 3 (depends on 1) The method of claim 1, wherein some antennas are installed at an outer side of the terminal or device while the others are installed within the terminal or device. ### Claim 4 (depends on 1) The method of claim 1, wherein the channel state information comprises a reception power (RSRP) and a bit error rate (BER) of each antenna. ### Claim 5 (depends on 1) The method of claim 1, wherein the channel state information comprises a reception performance (CQI) and a reception power (Pwr) of each antenna. ### Claim 6 (depends on 1) The method of claim 1, wherein the antenna adjustment information is displayed in the form of a list in a pop-up window or in the form of a message. ### Claim 7 (depends on 1) The method of claim 1, wherein the antenna adjustment information is displayed in color, a character size or in the form of a check box so as to be discriminated from other antennas. ### Claim 8 (depends on 1) The method of claim 1, wherein when the multiple antennas are external antennas, the antenna adjustment information indicates external antennas that need to be adjusted. ### Claim 9 (depends on 1) The method of claim 1, wherein when the multiple antennas are internal antennas, the antenna adjustment information indicates a direction in which the internal antennas are positioned. ### Claim 10 (depends on 1) The method of claim 1, wherein when the multiple antennas include both internal antennas and external antennas, the antenna adjustment information indicates external terminals to be adjusted and a direction in which the internal antennas are positioned. ### Claim 11 (depends on 1) The method of claim 1, wherein the displaying of the antenna adjustment information comprises: determining a channel state of each antenna based on the measured channel state information; checking an antenna setting mode in a user menu; if the antenna setting mode is a general user mode, displaying whether or not antennas are to be adjusted on a screen; and if the antenna setting mode is an expert mode, displaying the measured channel state information on the screen. ### Claim 12 (depends on 11) The method of claim 11, wherein the displayed channel state information comprises a reception power (RSRP) and a bit error rate (BER) of each antenna. ### Claim 13 (depends on 11) The method of claim 11, wherein the displayed channel state information comprises a reception performance (CQI) and a reception power (Pwr) of each antenna. ### Claim 14 (depends on 1) The method of claim 1, wherein when the mobile terminal is performing handover, the antenna adjustment information is be displayed on the screen. ### Claim 15 A mobile terminal comprising: multiple antennas configured to receive a downlink signal; a memory configured to store an antenna setting mode; and a controller configured to measure a channel state of each antenna and displaying antenna adjustment information on a screen according to the measured channel state information and the stored antenna setting mode. ### Claim 16 (depends on 15) The mobile terminal of claim 15, wherein the multiple antennas are configured as external antennas or internal antennas of a terminal or a device, or configured to include some installed at an outer side of the terminal or device and the other installed within the terminal or device. ### Claim 17 (depends on 15) The mobile terminal of claim 15, wherein the channel state information comprises a reception power (RSRP) and a bit error rate (BER) of each antenna. ### Claim 18 (depends on 15) The mobile terminal of claim 15, wherein the channel state information comprises a reception performance (CQI) and a reception power (Pwr) of each antenna. ### Claim 19 (depends on 15) The mobile terminal of claim 15, wherein the antenna adjustment information comprises an antenna list indicating whether or not each antenna needs to be adjusted, or an antenna which needs to be adjusted. ### Claim 20 (depends on 19) The mobile terminal of claim 19, wherein the antenna adjustment information is displayed in a pop-up window or in the form of a message. ### Claim 21 (depends on 19) The mobile terminal of claim 19, wherein the antennas that need to be adjusted on the antenna list are displayed to be discriminated from other antennas by using color, a character size or a check box. ### Claim 22 (depends on 15) The mobile terminal of claim 15, wherein when the multiple antennas are external antennas, the controller displays the external antennas that need to be adjusted on the screen. ### Claim 23 (depends on 15) The mobile terminal of claim 15, wherein when the multiple antennas are internal antennas, the controller displays a direction in which the internal antennas to be adjusted are positioned. ### Claim 24 (depends on 15) The mobile terminal of claim 15, wherein when the multiple antennas comprise both internal antennas and external antennas, the controller displays external antennas to be adjusted and a direction in which the internal antennas are positioned. ### Claim 25 (depends on 15) The mobile terminal of claim 15, wherein when the mobile terminal is performing handover, the controller does not display the antenna adjustment information on the screen.
