COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND COMMUNICATION DEVICE

Document Type and Number:

Japanese Patent JP2014146994

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a communication system, a communication method, and a communication device designed to secure a carrier bandwidth to speed up communication in a communication scheme such as TD-LTE, and capable of preventing radio wave interferences with other systems by suppressing to within a frequency band (e.g., 9 MHz band) allocated to the communication scheme.SOLUTION: Provided is a communication system 1 equipped with a plurality of communication devices for performing radio communication by arranging a plurality of carriers in such a second frequency band as to exceed the bandwidth of a second frequency band for which the second frequency band is predefined that carriers in a first frequency band are contiguously arranged. In the communication system 1, each carrier is arranged by partly overlapping in the second frequency band, a communication device 10a using a carrier A, which is one of carriers arranged while partly overlapping each other in the second frequency band, does not use an overlapping portion included in the carrier A.
