Title:
RADIO COMMUNICATION APPARATUS, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/173119
Kind Code:
A1
Abstract:
In a radio communication in which a plurality of channels (sub-bands) are used to perform communications and further the frequencies of the plurality of channels that are used are caused to hop in a predetermined period, it is intended to make it possible to perform a control that is optimal as a whole. For this purpose, a radio communication apparatus comprises: a transmission unit 201 that divides transmission data into a plurality of transmission streams and then encodes and modulates each of the plurality of transmission streams according to a transmission parameter that is set for each transmission stream; a transmission frequency conversion unit 202 that converts the transmission streams to radio frequency signals that hop the subcarriers included in mutually different sub-band frequencies; and a transmission power control unit 203 that controls the transmission powers of the radio frequency signals according to a transmission parameter that is set for each plurality of transmission streams, wherein the transmission parameter that is set for each plurality of transmission streams satisfies a transmission rate specified in advance under the reception qualities of the sub-band frequencies at which the plurality of transmission streams are transmitted, and is set on the basis of an criterion specified for the entirety of the plurality of transmission streams.
