Title:
TRANSMISSION DEVICE, COMMUNICATION SYSTEM, TRANSMISSION METHOD, AND TRANSMISSION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/013894
Kind Code:
A1
Abstract:
The present invention provides a transmission device, a communication system, a transmission method, and a transmission program that improve transmission efficiency and communication quality in carrier aggregation (CA). The invention is characterized in that a first access method is used for signals of at least a first bandwidth of a plurality of bandwidths, a second access method is used for signals of another at least second bandwidth of the plurality of bandwidths, and the signals of the respective bandwidths are transmitted. The invention is also characterized in that the first access method is frequency spreading, and the second access method is frequency division multiplexing.
