Abstract
Provided are a method and apparatus for transmitting an uplink control signal in a wireless communication system. A terminal receives one antenna port in a good channel state or one indicator that indicates precoding, which is selected by a base station, from the base station; and transmits the uplink control signal through a physical uplink control channel (PUCCH) to the selected one antenna port or the selected one precoding.
Claims17
A method of transmitting, by a user equipment (UE), an uplink control signal in a wireless communication, the method comprising:
- receiving an indicator indicating one antenna port which is selected by a base station and has a good channel state, from the base station;
- and
- transmitting the uplink control signal on the selected one antenna port through a physical uplink control channel (PUCCH).
A method of selecting, by a base station, an antenna port in a wireless communication system, the method comprising:
- receiving, from a user equipment (UE), an uplink control signal on two antenna ports through a physical uplink control channel (PUCCH);
- selecting one antenna port with a better channel state among the two antenna ports based on the received uplink control signal;
- and
- transmitting an indicator indicating the selected antenna port to the UE.
A method of transmitting, by a user equipment (UE), an uplink control signal in a wireless communication system, the method comprising:
- receiving an indicator indicating one precoding which is selected by a base station, from the base station;
- and
- transmitting the uplink control signal on the selected precoding through a physical uplink control channel (PUCCH).
