Abstract: Methods and apparatuses in a communication system is provided. One or more configurations associated with an aperiodic channel state information (CSI) report are received from a base station via higher layer signaling. Downlink control information (DCI) including a CSI request field indicating a configuration among the one or more configurations is received from the base station. The aperiodic CSI report is transmitted to the base station based on the configuration. In case that a medium access control (MAC) control element (CE) is used to map the configuration to a value of the CSI request field based on a number of the one or more configurations and a size of the CSI request field, the CSI request field indicates the configuration from at least one configuration selected via the MAC CE.

Abstract: Disclosed are methods performed by a base station in a wireless communication system including identifying a number of orthogonal frequency division multiplexing (OFDM) symbols for a terminal; identifying downlink control information (DCI) format for the terminal, generating DG for the terminal based on a resource allocation type and resource block group for data transmission of the terminal, wherein the resource allocation type is identified based on the DCI format transmitting, to the terminal, the DCI; and transmitting, to the terminal, data corresponding to the DCI. The resource block group includes consecutive virtual resource blocks and a number of the consecutive virtual resource blocks is determined based on a size of a bandwidth and a configuration information by a higher layer signaling.

Abstract: A method and a device for transmitting or receiving uplink control information in a wireless communication system are provided. The method includes receiving, from a base station, an indicator indicating whether hybrid automatic repeat request acknowledgement (HARQ-ACK) information and configured grant-uplink control information (CG-UCI) are to be joint-encoded, identifying that a transmission of the HARQ-ACK information overlaps with a configured grant-physical uplink shared channel (CG-PUSCH) transmission, when the indicator indicates the HARQ-ACK information and the CG-UCI are to be joint-encoded, performing a joint-encoding of the HARQ-ACK information and the CG-UCI, determining a number of coded modulation symbols for the HARQ-ACK information and the CG-UCI based on a beta offset value for the HARQ-ACK information, and transmitting, to the base station, uplink data on the CG-PUSCH with the HARQ-ACK information and the CG-UCI based on the determined number of coded modulation symbols.
