METHOD AND USER EQUIPMENT FOR TRANSMITTING UPLINK CONTROL INFORMATION

摘要

In the event ACK/NACK information on downlink data transmitted on one or more carriers must be transmitted on a PUCCH together with SR, user equipment of the present invention always modulates the ACL/NACK information to a first complex modulation symbol regardless of the number of the carriers when a specific carrier is ACK and the other carriers are NACKs, or the specific carrier is ACK and ACK/NACK bundled for the other carriers is NACK. Also, the user equipment always modulates the ACK/NACK information to a second complex modulation symbol regardless of the number of the carriers when a specific carrier is NACK and the other carriers are NACKs, or the specific carrier is ACK and the ACK/NACK bundled for the other carriers is NACK. According to the present invention, regardless of the number of carriers needed for the user equipment, at least ACK/NACK information on the specific carrier can be exactly transmitted to a base station.
