TERMINAL AND METHOD FOR RECEIVING DATA THROUGH UNLICENSED BAND
First Claim
1. A method of receiving data by a terminal using both a licensed band and an unlicensed band for communicating with a mobile communication base station, the method comprising:
- transmitting, through the unlicensed band, a Clear To Send (CTS) frame defined by a Wireless LAN (WLAN) system, before receiving a data channel from the mobile communication base station; and
at a specific frame or a specific subframe, receiving, through the unlicensed band and from the mobile communication base station, a data channel after transmitting the CTS frame, andwherein the specific frame or a specific subframe by which the data channel is received, is a frame or a subframe used in a mobile communication system by which is operated on the licensed band.
