Devices for sending and receiving feedback information

A User Equipment for sending information to an evolved Node B, comprising:

• an operator configured to set a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell (PCell) and a TDD UL-DL configuration of a secondary cell (SCell), wherein the TDD UL-DL configuration of the PCell and the TDD UL-DL configuration of the SCell are not same;
• and
• a transmitter configured to transmit Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement information on a Physical Uplink Control Channel (PUCCH) Format 1 b with channel selection;
• wherein
• the PUCCH Format 1b with the channel selection is not used in a case where TDD UL-DL configuration 5 is utilized as a reference configuration of the SCell.

An evolved Node B (eNB) for receiving information from a User Equipment, the eNB comprising:

• an operator configured to determine a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell (PCell) and to determine a TDD UL-DL configuration of a secondary cell (SCell), wherein the TDD UL-DL configuration of the PCell and the TDD UL-DL configuration of the SCell are not same;
• and
• a receiver configured to receive Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement information on a Physical Uplink Control Channel (PUCCH) Format 1b with channel selection;
• wherein
• the PUCCH Format 1b with the channel selection is not supported in a case where TDD UL-DL configuration 5 is utilized as a reference configuration of the SCell.

A method for sending information with a User Equipment, the method comprising:

• setting a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell (PCell) and a TDD UL-DL configuration of a secondary cell (SCell), wherein the TDD UL-DL configuration of the PCell and the TDD UL-DL configuration of the SCell are not same;
• and
• transmitting Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement information on a Physical Uplink Control Channel (PUCCH) Format 1 b with channel selection;
• wherein
• the PUCCH Format 1b with the channel selection is not used in a case where TDD UL-DL configuration 5 is utilized as a reference configuration of the SCell.
