Abstract: A method for transmitting and receiving signals for ultra reliable low latency communication. A method of operating a terminal includes: receiving, from a base station, first DCI including resource allocation information of a first PDSCH; performing a blind decoding operation on a PDCCH candidate when a resource region of the first PDSCH indicated by the first DCI overlaps with a resource region of the PDCCH candidate; and performing a receiving operation of a downlink channel on the basis of a result of the blind decoding operation. Therefore, the performance of a communication system can be improved.

Abstract: Disclosed are CSI feedback methods and apparatuses in a communication system supporting sidelink communication. An operation method of a first terminal may comprise transmitting CSI request information for requesting transmission of a channel state information (CSI) report to a second terminal; receiving a CSI report #1 for a sidelink between the first terminal and the second terminal from the second terminal through a sidelink channel; and transmitting one or more CSI reports among the CSI report #1 and a CSI report #2 for a communication link between the first terminal and a base station to the base station through an uplink channel. Therefore, the performance of the communication system can be improved.

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.

Abstract: Disclosed are a method and an apparatus for transmitting or receiving uplink feedback information in a communication system. An operation method of a terminal may comprise receiving downlink control information (DCI) from a base station, the DCI including resource allocation information of a physical downlink shared channel (PDSCH); receiving data # n from the base station through the PDSCH indicated by the DCI; generating a hybrid automatic repeat request (HARQ) codebook including an HARQ response bit # n for the data # n and an HARQ response bit # n−1 for data # n−1 received from the base station before the data # n; and transmitting the HARQ codebook to the base station. Therefore, the performance of the communication system can be improved.
