TRANSMISSION DEVICE, RECEPTION DEVICE, WIRELESS COMMUNICATION SYSTEM, AND METHOD AND PROGRAM FOR USE WITH TRANSMISSION DEVICE, RECEPTION DEVICE, AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/173466
Kind Code:
A1
Abstract:
The present invention improves cellular communication transmission efficiency over the entirety of a wireless communication system. According to the present invention, a transmission device transmits a non-orthogonal frequency division multiplexed signal to a reception device over a wireless communication system. The transmission device comprises a compression control unit and a signal generation unit. The compression control unit performs compression control that is for subcarrier compression that, for every prescribed resource within a frequency resource, narrows subcarrier interval without changing subcarrier width. The signal generation unit generates the non-orthogonal frequency division multiplexed signal on the basis of the compression control performed by the compression control unit.
