Title:
COMMUNICATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/068747
Kind Code:
A1
Abstract:
A communication device (2900) of a disclosure of the present invention is provided with: a signal processing unit (2901) that adjusts the transmission timing and/or frequency such that modulation symbol sequences addressed to terminals are transmitted by frames corresponding to the communicable ranges to which the terminals belong, from among a plurality of frames prescribed by time and frequency band; and a weighting synthesis unit (2902) that weights each modulation symbol sequence, and transmits same from an antenna element. The frames are configured such that the number of modulation symbol sequences which can be simultaneously transmitted by the same time band and same frequency band differs in accordance with the communicable range, and include sub-frames prescribed by the time division and/or frequency division of the frames. The signal processing unit allocates modulation symbol sequences not greater than the number of simultaneously communicable modulation symbol sequences to sub-frames.
