Abstract: A method for receiving a PDCCH by a terminal in a mobile communication system may comprise the steps of: receiving a first PDCCH including first DCI from a base station through a first PDCCH search space; and receiving a second PDCCH including second DCI from the base station through a second PDCCH search space, wherein the first DCI and second DCI are for scheduling the same PDSCH for the same TB or TBs associated with the same HARQ process, are for scheduling different PDSCHs for the same TB or TBs associated with the same HARQ process, or are for scheduling different PDSCHs for different TBs or TBs associated with different HARQ processes. In addition, the first DCI and second DCI may be received from the base station within a time window.

Abstract: Disclosed are a measurement method and a measurement apparatus for supporting mobility in a communication system. An operation method of a terminal may comprise receiving, from a base station, control information including first information indicating one or more physical uplink shared channel (PUSCH) interlaces configured in an unlicensed band; identifying frequency resources corresponding to the one or more PUSCH interlaces; and transmitting a PUSCH to the base station using the frequency resources of the unlicensed band. Thus, 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.
