Data transmitting method using power detection, and device thereof

摘要

The present invention relates to a data transmitting method using power detection of an adjacent channel. The method comprises detecting power for a selected channel; determining an occupancy state of the channel by comparing the detected power with a threshold power; detecting power for a channel adjacent to the channel if the channel is in an unoccupied state on the basis of the determined result; determining a state of the adjacent channel by comparing the detected power for the adjacent channel with the minimum threshold power and the maximum threshold power; and transmitting data by using the channel on the basis of the determined results.

1. A method of transmitting data at a transmitter using power detection of an adjacent channel, the method comprising:
detecting power of a selected channel; determining an occupancy state of the selected channel by comparing the detected power with threshold power; detecting power of the adjacent channel of the selected channel if it is determined that the selected channel is not occupied; determining the state of the adjacent channel by comparing the detected power of the adjacent channel with minimum threshold power and maximum threshold power; and transmitting the data using the selected channel based on the determined adjacent channel state result, wherein the selected channel and/or the adjacent channel is a frequency bandwidth used in a long term evolution (LTE) system, and wherein the determining the state of the adjacent channel includes:
determining that data is being received using the adjacent channel data if the power of the adjacent channel is equal to or greater than the minimum threshold power and is equal to or less than the maximum threshold power;determining that data is being transmitted using the adjacent channel if the power of the adjacent channel is greater than the maximum threshold power; anddetermining that the adjacent channel is not occupied if the power of the adjacent channel is less than the minimum threshold power.
