USER DEVICE, RADIO BASE STATION, AND METHOD |
摘要 |
A mobile communications system includes a radio base station and a remote radio apparatus connected with a high-speed transmission medium to the radio base station. A user apparatus includes a unit which measures a received level of a signal transmitted from the radio base station and a received level of a signal transmitted from the remote radio apparatus and detects a change in relative magnitudes of measured values; a unit which measures a path loss between the user apparatus and the radio base station and a path loss between the user apparatus and the remote radio apparatus and detects a change in relative magnitudes of measured values; and a transmitter which transmits a report signal which shows that a predetermined event has occurred. The predetermined event occurs if the relative magnitudes of the received levels are reversed and/or if the relative magnitudes of the path losses are reversed. |
