Patent ID: 8649449

Claim:
A reception apparatus comprising: a digital information reception unit that wirelessly receives digital information from a sending apparatus using a certain channel, wherein the sending apparatus is configured to be able to support a plurality of transmission modes that use different occupied frequency bands in the channel, the reception apparatus further comprising: a transmission rate information reception unit that wirelessly receives information regarding a transmission rate necessary for transmission of the digital information from the sending apparatus; a transmission mode determination unit that determines a transmission mode at least on the basis of the transmission rate information received by the transmission rate information reception unit and setting information relating to electrical power consumption; and a transmission mode information sending unit that wirelessly sends information regarding the transmission mode determined by the transmission mode determination unit to the sending apparatus, wherein the plurality of transmission modes that can be supported by the sending apparatus include a first number of first transmission modes that use a first portion of a band of the channel as an occupied frequency band and a second number of second transmission modes that use a second portion of a band of the channel as an occupied frequency band, in which the second portion of the band is less than the first portion of the band, and wherein, when the setting information relating to the electrical power consumption indicates a first power consumption level, the transmission mode determination unit determines a transmission mode to be used in the sending apparatus from among the first number of first transmission modes and when the setting information relating to the electrical power consumption indicates a second power consumption level which is less than the first power consumption level, the transmission mode determination unit determines the transmission mode to be used in the sending apparatus from among the second number of second transmission modes.
