Apparatus and method for transmitting uplink control information through a physical uplink control channel
First Claim
1. A User Equipment (UE) for transmitting uplink control information through a Physical Uplink Control Channel (PUCCH), the UE comprising:
- a transceiver; and
a processor operationally coupled to the transceiver and configured to;
configure serving cells for the UE, the serving cells comprising at least six serving cells configurable for the UE;
receive PUCCH format configuration information for transmitting uplink control information associated with the configured serving cells, the PUCCH format configuration information comprising configuration information of PUCCH format 4 indicated by a Radio Resource Control (RRC) message;
determine a total number of Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) bits, scheduling request (SR) bits, and periodic Channel State Information (CSI) bits to be transmitted in a subframe;
select, at least based on the determined total number, a PUCCH format to transmit at least one of HARQ-ACK, SR, and periodic CSI in the subframe, the selected PUCCH format being one of PUCCH formats comprising the PUCCH format 4 and PUCCH format 3, wherein the selecting the PUCCH format comprises;
determine that simultaneousAckNackAndCQI-Format4-r13 is set true and determining that the total number of HARQ-ACK bits, SR bits, and periodic CSI bits to be transmitted in the subframe is less than or equal to a threshold value; and
determine to use the PUCCH format 4 without dropping the periodic CSI; and
transmit the uplink control information associated with the configured serving cells in the subframe using the selected PUCCH format, the uplink control information associated with the configured serving cells comprising the at least one of HARQ-ACK, SR, and periodic CSI,wherein the processor is further configured to determine whether the total number of HARQ-ACK bits, SR bits, and periodic CSI bits to be transmitted in a subframe is greater than 22; and
select the PUCCH format 4 when the determined total number is greater than 22.

Abstract
A method includes configuring serving cells for UE, the serving cells including at least six serving cells configurable for the UE; receiving PUCCH format configuration information for transmitting uplink control information associated with the configured serving cells, the PUCCH format configuration information including configuration information of PUCCH format 4; determining a total number of HARQ-ACK bits, SR bits, and periodic CSI bits to be transmitted in a subframe; selecting, at least based on the determined total number, a PUCCH format to transmit at least one of HARQ-ACK, SR, and periodic CSI, the selected PUCCH format being one of PUCCH formats including the PUCCH format 4 and PUCCH format 3; and transmitting the uplink control information associated with the configured serving cells in the subframe using the selected PUCCH format, the uplink control information associated with the configured serving cells including the at least one of HARQ-ACK, SR, and periodic CSI.
