Abstract
Official abstract text for this publication.
Disclosed are a radio terminal device and the like, which achieve an improvement in the accuracy of ranging between a UWB reader and a UWB tag regardless of whether an active method or a semi-passive method. In a terminal ( 300 ), a timing control unit ( 340 ) outputs, to a transmission amplifier ( 350 ), a control signal for performing on-off control such that on the basis of the reception timing of a pulse signal transmitted from a base station ( 200 ) and a representative value of a circuit delay time required from when a reception pulse signal is received until a transmission pulse signal generated in response to a detection signal of the reception pulse signal is transmitted, the transmission amplifier ( 350 ) amplifies a reradiation pulse generated in response to a detection signal of the pulse signal transmitted from the base station ( 200 ); and a re-reradiation pulse generated in response to a detection signal of the reradiation pulse.
First claim
Opening claim text (preview).
The invention claimed is: 1. A radio terminal apparatus in a radio distance measurement system that measures a distance between the radio terminal apparatus and a radio base station apparatus using a pulse signal, the radio terminal apparatus comprising: a reception antenna configured to receive the pulse signal from the radio base station apparatus; a detector that detects the received pulse signal and outputs a first detection signal based on the received pulse signal, and tha…
