摘要:
In a wireless communication system, a terminal device and a base station device communicate using frequency bands selected from among a plurality of frequency bands. The base station device selects a frequency band used for a downlink and a frequency band used for an uplink as frequency bands used for communication with the terminal device from among the plurality of frequency bands, selects an association between the frequency band used for the downlink and the frequency band used for the uplink among the selected frequency bands, and transmits information indicating the selected frequency bands and information indicating the association containing identification information of the association using a signal specific to the terminal device.
摘要:
A wireless communication apparatus includes: a receiving unit that receives a signal indicating a frequency band having the highest priority of selection among a plurality of frequency bands; and a transmitting unit that transmits data in parallel, using the frequency band having the highest priority of selection and a frequency band having a priority of selection lower than that of the frequency band having the highest priority of selection.
摘要:
A wireless communication system includes a terminal station apparatus and a base station apparatus which transmits data to the terminal station apparatus using a plurality of component carriers that are communication frequency bands in which wireless communication is performed. The base station apparatus includes: a frequency band determination unit which determines component carriers in which data is transmitted and notifies the terminal station apparatus of the determined component carriers on the basis of radio quality of each of the plurality of component carriers when transmission of the data to the terminal station apparatus is initiated or when the component carriers to be used for transmission of the data to the terminal station apparatus are changed.
摘要:
A transmitter which communicates with a receiver. The transmitter includes a null subcarrier allocation unit which allocates a null subcarrier based on a priority and a signal. The priority is for allocating a null subcarrier to each subcarrier. The priority is a ranking predetermined with the receiver. The signal is allocated to each subcarrier. The transmitter includes a transmission unit which transmits the signal using the subcarrier allocated by the null subcarrier allocation unit as the null subcarrier to the receiver.
