Abstract
Official abstract text for this publication.
A radio apparatus in a radio communication system that includes the radio apparatus and a signal processing apparatus that function as a base station, includes a channel estimation unit that, on the basis of a radio signal transmitted from a terminal apparatus, measures a reception quality of the radio signal; and a transmission control unit that, on the basis of the reception quality measured by the channel estimation unit, controls transmission, to the signal processing apparatus, of bit data or a log likelihood ratio obtained from the radio signal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A radio apparatus in a radio communication system that comprises the radio apparatus and a signal processing apparatus that function as a base station, the radio apparatus comprising: a channel estimation unit that, on the basis of a radio signal transmitted from a terminal apparatus, measures a reception quality of the radio signal; and a transmission control unit that, on the basis of the reception quality measured by the channel estimation unit, controls transmission, to the signal processing apparatus, of bit data or a log likelihood ratio obtained from the radio signal, wherein, when the reception quality is less than a predetermined threshold value, the transmission control unit discards the bit data or the log likelihood ratio without transmission to the signal processing apparatus, and notifies the signal processing apparatus that the bit data or the log likelihood ratio will not be transmitted to the signal processing apparatus. 2. The radio apparatus according to claim 1 , wherein the channel estimation unit measures, as the reception quality, any one of a received signal power, a received SNR (Signal to Noise Ratio), and a received SINR (Signal to Interference plus Noise Ratio). 3. A radio communication method performed by a radio apparatus in a radio communication system that comprises the radio apparatus and a signal processing apparatus that function as a base station, the radio communication method comprising: a channel estimation step of measuring, on the basis of a radio signal transmitted from a terminal apparatus, a reception quality of the radio signal; and a transmission control step of controlling, on the basis of the reception quality measured in the channel estimation step, transmission, to the signal processing apparatus, of bit data or a log likelihood ratio obtained from the radio signal, wherein, when the reception quality is less than a predetermined threshold value, the transmission control step discards the bit data or the log likelihood ratio without transmission to the signal processing apparatus, and notifies the signal processing apparatus that the bit data or the log likelihood ratio will not be transmitted to the signal processing apparatus.
