Method and apparatus for transmitting HARQ-ACK feedback information in an enhanced carrier aggregation system

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, a control message configuring physical uplink control channel (PUCCH) resource sets including a first PUCCH resource set and a second PUCCH resource set, via a higher layer signaling, wherein each PUCCH resource set includes a plurality of PUCCH resources, and each PUCCH resource corresponds to a PUCCH format among a plurality of PUCCH formats, and wherein the control message includes a value indicating a maximum number of uplink control information (UCI) bits for a PUCCH resource set,
• receive, from the base station, downlink control information (DCI) including information indicating a PUCCH resource,
• generate UCI including hybrid automatic repeat request acknowledgement (HARQ-ACK) information,
• identify whether the PUCCH resource indicated by the information corresponds to the first PUCCH resource set or the second PUCCH resource set, based on a number of bits of the UCI and the value indicating the maximum number of UCI bits, wherein the PUCCH resource corresponds to the first PUCCH resource set, in case that the number of bits of the UCI is more than the value, and wherein the PUCCH resource corresponds to the second PUCCH resource set, in case that the number of bits of the UCI is equal to or less than the value,
• identify, based on the information, the PUCCH resource for the UCI and a corresponding PUCCH format among the identified PUCCH resource set,
• identify whether second information indicating that the HARQ-ACK information and channel state information (CSI) are transmittable simultaneously on a same PUCCH resource is configured by the higher layer signaling, and
• in case that the second information is not configured by the higher layer signaling, drop the CSI and transmit, to the base station, the UCI including the HARQ-ACK information on the PUCCH resource based on the PUCCH format.

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a control message configuring physical uplink control channel (PUCCH) resource sets including a first PUCCH resource set and a second PUCCH resource set, via a higher layer signaling, wherein each PUCCH resource set includes a plurality of PUCCH resources, and each PUCCH resource corresponds to a PUCCH format among a plurality of PUCCH formats, and wherein the control message includes a value indicating a maximum number of uplink control information (UCI) bits for a PUCCH resource set;
• transmitting, to the terminal, downlink control information (DCI) including information for indicating a PUCCH resource;
• and
• receiving, from the terminal, UCI including hybrid automatic repeat request acknowledgement (HARQ-ACK) information,
• wherein whether the PUCCH resource indicated by the information corresponds the first PUCCH resource set or the second PUCCH resource set is identified based on a number of bits of the UCI and the value indicating the maximum number of UCI bits,
• wherein the PUCCH resource corresponds to the first PUCCH resource set, in case that the number of bits of the UCI is more than the value,
• wherein the PUCCH resource corresponds to the second PUCCH resource set, in case that the number of bits of the UCI is equal to or less than the value,
• wherein the PUCCH resource for the UCI and a corresponding PUCCH format are identified among the identified PUCCH resource set, based on the information,
• wherein the UCI is received on the PUCCH resource based on the PUCCH format, and
• wherein in case that second information indicating that the HARQ-ACK information and channel state information (CSI) are transmittable simultaneously on a same PUCCH resource is not configured by the higher layer signaling, the CSI is dropped and the UCI only includes the HARQ-ACK information.
