Abstract
A method and an apparatus for controlling power of an uplink in a beam forming system is disclosed. The method includes generating power control information based on a quality of a signal which is measured for each reception beam of a base station, so as to transmit the power control information to terminals. The method also includes receiving a signal transmitted by using the power control information from at least one terminal.
Claims22
A method to control power of an uplink, at a base station, in a wireless communication system, the method comprising:
- generating power control information for reception beams of the base station based on signals received using the reception beams;
- transmitting, to a terminal, the power control information;
- transmitting, to the terminal, a reception beam identifier of a reception beam determined among the reception beams;
- and
- receiving, from the terminal, a signal transmitted using a transmission power which is determined based on the reception beam identifier and the power control information.
A method to control power of an uplink at a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, power control information generated based on signals received using reception beams of the base station;
- receiving, from the base station, a reception beam identifier of a reception beam determined among the reception beams;
- determining a transmission power of a signal based on the reception beam identifier and the power control information;
- and
- transmitting the signal to the base station using the determined transmission power.
A base station to control power of an uplink in a wireless communication system, the base station comprising:
- a controller configured to generate power control information for reception beams of the base station based on signal received by the reception beams;
- a transceiver configured to:
- transmit, to a terminal, the power control information, and
- transmit, to the terminal, a reception beam identifier of a reception beam determined among the reception beams, and
- receive, a signal transmitted using a transmission power that is determined based on the reception beam identifier and the power control information from the terminal.
A terminal to control power of an uplink in a wireless communication system, the terminal comprising:
- a transceiver configured to receive, from a base station, power control information generated based on signals received using reception beams of the base station, and receive, from the base station, a reception beam identifier of a reception beam determined among the reception beams;
- and
- a controller configured to:
- determine a transmission power of a signal based on the reception beam identifier and the power control information, and
- control the transceiver to transmit the signal to the base station using the determined transmission power.
