Title:
APPARATUS AND METHOD FOR COORDINATING IN-DEVICE COEXISTENCE INTERFERENCE IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/096527
Kind Code:
A3
Abstract:
The present description relates to an apparatus and method for coordinating in-device coexistence interference in a wireless communication system. The method of the present invention comprises the following steps: performing triggering for making a request to a base station for the coordination of interference between transmission in a first frequency band of a first network system by a terminal, and reception in a second frequency band of a second network system by said terminal; transmitting mixed support information to the base station, wherein the mixed support information includes first support information for supporting FDM scheme-based coordination of said interference in a frequency domain, and second support information for supporting TDM scheme-based coordination of said interference in a time domain; and receiving, from the base station, response information for accepting or rejecting the coordination of said interference as a response to the mixed support information. According to the present description, procedures for processing in-device coexistence interference may be simplified and easily performed, and backward compatibility between the procedures of the present invention and existing procedures may be maintained.
