Control information transmission method and apparatus for use in mobile communication system
First Claim
1. A method for controlling information transmission of a first terminal in a first network in a mobile communication system, the method comprising:
- receiving first control information from a base station using a first radio protocol;
acquiring channel occupancy information based on the first control information;
generating second control information based on the channel occupancy information; and
transmitting the second control information to a second terminal in a second network using a second radio protocol,wherein the second control information comprises a clear-to-send (CTS) packet including channel occupancy information, andwherein the transmitting of the second control information comprises;
calculating a transmission start time for starting transmission of the second control information based on the first control information, andtransmitting the second control information at the transmission start time.

Abstract
A method of control information transmission for a terminal in a mobile communication system, and an apparatus therefor are provided. In the method of control information transmission, the terminal acquires unlicensed frequency channel occupancy information based on the control information received from a base station and transmits the unlicensed frequency channel occupancy information to other terminals operating on the same unlicensed frequency. The method of control information transmission includes receiving a first control information from a base station using a first radio communication protocol, acquiring channel occupancy information based on the first control information, and transmitting a second control information including the channel occupancy information to another terminal using a second radio communication protocol.
