Title:
COMMUNICATION CONTROL DEVICE, COMMUNICATION CONTROL METHOD, WIRELESS COMMUNICATION SYSTEM, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/001840
Kind Code:
A1
Abstract:
[Problem] To achieve a mechanism whereby it is possible to prevent damaging interference in secondary usage of a frequency channel, at low cost. [Solution] In a wireless communication system having a primary base station which is connected by a primary terminal and a secondary base station which is connected by a secondary terminal for secondary use of a frequency channel for the primary base station, provided is a communication control device comprising: an acquisition unit which acquires a quality report including a communication quality index which is measured by the primary terminal and/or a quality report including a communication quality index which is measured by the secondary terminal; and an interference control unit which issues instructions to reduce transmission power for the secondary base station when it is determined that damaging interference occurs in the wireless communication system, on the basis of the communication quality indices included in the quality reports which are acquired by the acquisition unit.
