Abstract: Methods and apparatuses are provided in which it is determined to transmit a physical uplink control channel (PUCCH) with a positive scheduling request (SR) and one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits in a PUCCH resource of a PUCCH format 0. A value mcs for a cyclic shift for the PUCCH format 0 is identified based on the positive SR and the one or more HARQ-ACK information bits. The positive SR and the one or more HARQ-ACK information bits are transmitted to the base station in the PUCCH resource of the PUCCH format 0, based on the value mcs.

Abstract: A communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT) is disclosed. A method of a terminal in a wireless communication system is provided. The method includes receiving downlink control information (DCI) including frequency domain resource allocation information on a physical downlink control channel (PDCCH) from a base station, identifying an allocated resource for transmitting or receiving data based on the frequency domain resource allocation information, and transmitting or receiving the data on the allocated resource. When the frequency domain resource allocation information is based on a first bandwidth part of a first bandwidth and the DCI is for a second bandwidth part corresponding to a second bandwidth, the allocated resource is identified by applying a scaling factor based on the first bandwidth and the second bandwidth.
