Communication repeater device, control method, and computer program product
Abstract:
According to an embodiment, a communication repeater device includes storage and a controller which detects, upon receiving a radio frame including pairs of orthogonal frequency division multiplexing symbols and cyclic prefixes from the radio base station, switching timing between uplink and downlink according to similarity between certain sections of an original radio frame and a time-shifted radio frame. The controller estimates the subsequent switching timing between the uplink and the downlink from the detected switching timing and frame information stored in the storage.
