Abstract: A method of a terminal may include: receiving, from a base station, a first SSB having an SSB candidate #n at a first frequency position during a first time period; receiving, from the base station, first mapping relationship information between SSB candidate indexes and SSB indexes; identifying an SSB #k mapped to the SSB candidate #n based on the first mapping relationship information for the first frequency position; acquiring time synchronization with respect to the base station based on the SSB candidate #n; and obtaining beam information for the first frequency position based on the SSB #k, wherein each of n and k is an integer equal to or greater than 0.

Abstract: A method for indicating preemption in a communication system is disclosed. A method for operating a terminal comprises the steps of: receiving, from a base station, information indicating a first resource area, to which a preemption-capable resource belongs, for transmission of first data; receiving resource allocation information of second data from the base station; performing a monitoring operation for detecting a PI indicating a preempted resource for transmission of the first data in the first resource area, when the first resource area overlaps with a second resource area indicated by the resource allocation information; and performing decoding on the basis of the detected PI. Therefore, the performance of the communication system may be improved.

Abstract: Feedback methods for repetitive uplink transmissions in a communication system are disclosed. An operation method of a terminal may comprise receiving DL data #1 from a base station through a DL data channel #1; receiving DL data #2 from the base station through a DL data channel #2; and when each of a UL control channel #1 on which an HARQ response #1 for the DL data #1 is to be transmitted and a UL control channel #2 on which an HARQ response #2 for the DL data #2 is to be transmitted overlaps with a UL data channel assigned by the base station, transmitting the HARQ response #1 and the HARQ response #2 to the base station through the UL data channel. Therefore, the performance of the communication system can be improved.

Abstract: Disclosed are various methods for transmitting or receiving data or control information having high reliability conditions. A method for operating a terminal which transmits uplink control information (UCI) includes: a step of generating UCI; a step of comparing the priority of an uplink (UL) control channel for the transmission of the UCI with the priority of a UL data channel when some symbols of the UL control channel and the UL data channel overlap; and a step of selecting the UL channel having a higher priority among the UL control channel and the UL data channel, and transmitting the UCI to a base station through the selected UL channel.

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 includes 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.
