Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a network device for forwarding information in a communication system is provided.

Abstract: A method and a corresponding apparatus for performing uplink transmission in a wireless communication system are disclosed. The method comprises: based on at least one of the information indicating uplink transmission resources, acquiring the number of resource elements REs used for determining a PUSCH transmission; determining a transport block size TBS for the uplink transmission based on the number of REs; and performing the uplink transmission based on the determined TBS. Wherein, a PUSCH transmission occupies m time unit for transmission, and the rate matching and RE mapping of the PUSCH are performed on all resources occupied in m time unit.

Abstract: The disclosure relates to a 5th Generation (5G) or 6th Generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) is provided. The method includes receiving, by the UE, a physical downlink control channel (PDCCH), wherein the received PDCCH includes downlink control information (DCI) for scheduling one or more physical downlink shared channels (PDSCHs), receiving, by the UE, one or more PDSCHs according to the received DCI, determining and transmitting, by the UE, a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook for one or more PDSCHs according to the received PDSCHs and PDCCH.

Abstract: The disclosure provides a method performed by a UE in a wireless communication system, including receiving a channel state information (CSI) reporting configuration comprising a plurality of first sub-configurations, and determining and reporting CSI based on a second sub-configuration comprising N out of the plurality of the first sub-configurations, where N is greater than or equal to 1, wherein the CSI comprises one or two CSI parts, wherein a number of the CSI parts included in the CSI is determined based on N, and wherein at least one of the one or two CSI parts included in the CSI is determined based on a first order including at least one of an order of the N first sub-configurations in the second sub-configuration, an order of CSI parameters in the CSI, and an order between zero-padding bits and the CSI parameters in the CSI.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure provides a method performed by a user equipment (UE) in a wireless communication system. The method includes: receiving, from a base station, channel state information (CSI) report configuration information including a list of sub-configurations; and transmitting, to the base station, a first CSI report for at least one sub-configuration associated with the list of sub-configurations.
