Abstract
A method and an apparatus for controlling uplink transmission power in a wireless communication system are provided. The apparatus receives transmit power command (TPC) monitoring information for receiving a plurality of TPCs for adjusting uplink transmission power for a plurality of serving cells. The apparatus obtains the plurality of TPCs by monitoring a downlink control channel on the basis of the TPC monitoring information.
Claims8
A method performed by a base station operating in a wireless communication system, the method comprising:
- transmitting transmit power command (TPC) monitoring information to adjust an uplink transmission power for a first physical uplink control channel (PUCCH) cell and a second PUCCH cell, the TPC monitoring information including a first TPC index assigned to the first PUCCH cell and a second TPC index assigned to the second PUCCH cell,
- wherein the base station is configured to manage a first set of serving cells and a second set of serving cells,
- wherein the first PUCCH cell is a cell which is capable of transmitting a first PUCCH in the first set of serving cells, and
- wherein the second PUCCH cell is a cell which is capable of transmitting a second PUCCH in the second set of serving cells;
- and
- transmitting a TPC payload on a downlink control channel, the TPC payload including a plurality of TPCs,
- wherein the first TPC index represents a first TPC for the first PUCCH cell from the plurality of TPCs and a second TPC index represents a second TPC for the second PUCCH cell from the plurality of TPCs.
A device configured to operate in a wireless communication system, the device comprising:
- a transceiver configured to transmit and receive a radio signal;
- and
- a processor connected to the transceiver and configured to:
- instruct the transceiver to transmit power command (TPC) monitoring information to adjust an uplink transmission power for a first physical uplink control channel (PUCCH) cell and a second PUCCH cell, the TPC monitoring information including a first TPC index assigned to the first PUCCH cell and a second TPC index assigned to the second PUCCH cell,
- wherein the device is configured to manage a first set of serving cells and a second set of serving cells,
- wherein the first PUCCH cell is a cell which is capable of transmitting a first PUCCH in the first set of serving cells, and
- wherein the second PUCCH cell is a cell which is capable of transmitting a second PUCCH in the second set of serving cells;
- and
- instruct the transceiver to transmit a TPC payload on a downlink control channel, the TPC payload including a plurality of TPCs,
- wherein the first TPC index represents a first TPC for the first PUCCH cell from the plurality of TPCs and a second TPC index represents a second TPC for the second PUCCH cell from the plurality of TPCs.
