First Claim
Patent Images
1. A repeating apparatus in a wireless communication system, comprising:
- a signal detection unit configured to receive a signal from a base station or a mobile station and detect strength of the signal;
a control unit configured to compare the signal strength detected by the signal detection unit with signal strength predetermined by the system and provide comparison information; and
an output signal control unit configured to receive the comparison information from the control unit and adjust and amplify gain of a signal transmitted to the base station or the mobile station.

7. A repeating method in a mobile communication system, comprising:
-
receiving a signal of an uplink or downlink and detecting strength of the signal; comparing the detected signal strength with predetermined signal strength provided by the system; and suspending transmission of the received signal to the uplink or downlink when the detected signal strength is smaller than the predetermined signal strength and waiting for a signal to be received, detected strength of the signal being larger than the predetermined signal strength. - View Dependent Claims (8)

9. An apparatus for generating a repeater control signal by a mobile station in a mobile communication system, comprising:
-
a detector configured to receive a signal from the repeater and detect a received SNR value; a reference value storage unit configured to store a requested SNR value requested by the system and a margin value; a comparator configured to compare the received SNR value with a sum of the requested SNR value and the margin value and provide comparison information; and a signal bit adding unit configured to add a predetermined first or second bit to a pilot channel based on the comparison information. - View Dependent Claims (10, 11, 12)
