Abstract: An operation method of a terminal for transmitting uplink control information (UCI) to a base station by multiplexing two or more UCIs in a single physical uplink control channel (PUCCH) includes: determining a first sequence corresponding to a value of a second UCI (UCI2) when the UCI2 is generated before completing transmission of a first UCI (UCI1) to the base station; modulating the first sequence by applying a modulation symbol corresponding to a value of the UCI1, and applying a orthogonal cover code (OCC) to the modulated first sequence to generate a second sequence; and transmitting the second sequence in at least one symbol position of symbols constituting the PUCCH.

Abstract: An operation method of a terminal in a communication system may comprise receiving a downlink data channel from a base station in a slot #n or a slot #(n−l); receiving a slot format indicator (SFI) indicating a format of a slot #(n+k) in which an uplink control information (UCI) is to be transmitted, from the base station in the slot #n; and transmitting the UCI including a hybrid automatic repeat request (HARQ) response for the downlink data channel to the base station in the slot #(n+k). Here, each of n and k may be an integer equal to or greater than 0, and l may be an integer equal to or greater than 1.

Abstract: Disclosed is a communication method in a wireless communication system on the basis of a carrier aggregation. The communication method on the basis of a carrier aggregation comprises the steps of: receiving a PDSCH from a base station via a subframe n of a TDD cell; and transmitting, to the base station, a PUCCH including a response to the PDSCH via a subframe n+4 of an FDD cell. Accordingly, an HARQ process may be performed efficiently.

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.

Abstract: Disclosed are methods and apparatuses for supporting BWP-based operations in sidelink communication. An operation method of a first terminal in a communication system may include receiving, from a base station, configuration information of a mapping relationship between an uplink (UL) bandwidth part (BWP) and a sidelink (SL) BWP; when a UL switching operation for the UL BWP is performed, performing an SL switching operation for the SL BWP mapped to the UL BWP based on the mapping relationship without separate signaling indicating execution of the SL switching operation; and performing sidelink communication with a second terminal in a switched SL BWP.
