摘要
Embodiments of the present disclosure provide a method for transmitting uplink control information. The method includes: a User Equipment (UE) receives Uplink Control Information UCI configuration information, wherein the UCI configuration information includes information for determining a periodicity, an offset and a Physical Uplink Control Channel PUCCH for Periodic-Channel State Information P-CSI to be report in one subframe and configuration information for transmission of Hybrid Automatic Retransmission reQuest-Acknowledgement HARQ-ACK; processes one or more kinds of UCI in the subframe, and transmits the UCI on resources using a PUCCH format. According to the method of the present disclosure, the transmit power for transmitting the UCI on the channel using the PUCCH format is optimized. During the transmission of the P-CSI, the PUCCH resource most preferable for the transmission of the P-CSI is determined. The uplink resource utilization ratio is increased.

What is claimed is:1. A method performed by a terminal in a communication system, the method comprising:receiving, from a base station, configuration information on one or more physical uplink control channel (PUCCH) resources for transmitting multiple channel state information (CSI); identifying a PUCCH resource for transmitting uplink control information (UCI) including the multiple CSI among the one or more PUCCH resources, based on a number of bits associated with the UCI; identifying power for transmission of the UCI based on a number of physical resource blocks (PRBs) corresponding to the PUCCH resource, and a ratio of the number of bits associated with the UCI and a number of resource elements for the UCI; and transmitting the UCI including the multiple CSI using the PUCCH resource based on the power for the transmission of the UCI. 2. The method of claim 1 , wherein the configuration information includes an index and a format for each of the one or more PUCCH resources. 3. The method of claim 1 , wherein the PUCCH resource is identified as a PUCCH resource corresponding to a number of bits which is smallest number being greater than or equal to the number of bits associated with the UCI among the one or more PUCCH resources. 4. The method of claim 1 , further comprising:selecting at least one CSI among the multiple CSI based on a priority value, in case that the number of bits associated with the UCI is greater than the greatest number of bits corresponding to the one or more PUCCH resources; and transmitting the UCI including the selected at least one CSI using a PUCCH resource corresponding to the greatest number of bits. 5. A method performed by a base station in a communication system, the method comprising:transmitting, to a terminal, configuration information on one or more physical uplink control channel (PUCCH) resources for transmitting multiple channel state information (CSI); and receiving uplink control information (UCI) including the multiple CSI using a PUCCH resource based on power for the transmission of the UCI, wherein the PUCCH resource for receiving the UCI including the multiple CSI is one among the one or more PUCCH resources, based on a number of bits associated with the UCI, and wherein the power for the transmission of the UCI is based on a number of physical resource blocks (PRBs) corresponding to the PUCCH resource, and a ratio of the number of bits associated with the UCI and a number of resource elements for the UCI. 6. The method of claim 5 , wherein the configuration information includes an index and a format for each of the one or more PUCCH resources. 7. The method of claim 5 , wherein the PUCCH resource is identified as a PUCCH resource corresponding to a number of bits which is smallest number being greater than or equal to the number of bits associated with the UCI among the one or more PUCCH resources. 8. The method of claim 5 , further comprising receiving the UCI including a selected at least one CSI using a PUCCH resource corresponding to the greatest number of bits,wherein the at least one CSI is selected among the multiple CSI based on a priority value, in case that the number of bits associated with the UCI is greater than the greatest number of bits corresponding to the one or more PUCCH resources. 9. A terminal in a communication system, the terminal comprising:a transceiver; and a controller configured to: receive, from a base station, configuration information on one or more physical uplink control channel (PUCCH) resources for transmitting multiple channel state information (C SI); identify a PUCCH resource for transmitting uplink control information (UCI) including the multiple CSI among the one or more PUCCH resources, based on a number of bits associated with the UCI; identify power for transmission of the UCI based on a number of physical resource blocks (PRBs) corresponding to the PUCCH resource, and a ratio of the number of bits associated with the UCI and a number of resource elements for the UCI; and transmit the UCI including the multiple CSI using the PUCCH resource based on the power for the transmission of the UCI. 10.
