Abstract: An operation method of a terminal in a communication system may comprise: receiving, from a base station, a first SSB; determining a RACH occasion associated with the first SSB; transmitting, to the base station, a PRACH preamble in the RACH occasion within a first radio resource to which a first SCS is applied; determining a slot to which the RACH occasion belongs based on a reference radio resource to which a reference SCS is applied instead of the first SCS; determining an RNTI for a random access procedure based on a slot index for the slot; and performing a reception operation of a response for the PRACH preamble by using the RNTI in the first radio resource.

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: A method by which a terminal operating in an unlicensed band transmits a signal includes the steps of: receiving, from a base station, configuration information about a carrier; receiving configuration information for configuring N (where N is an integer) guard band(s) for some frequency domains of the carrier; and transmitting a signal to the base station by using a first frequency domain of a bandwidth part belonging to the carrier, wherein the first frequency domain can be a domain excluding the N guard band(s) from the frequency domain of the bandwidth part.

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: The present invention relates to a resource allocation method and apparatus, and a signal transmission method, which are applicable to various technical scenarios of 5G New Radio (NR). A method for operating a communication node for resource allocation in a communication network includes: allocating first data and a first pilot for a first type service to a first block period of a first subframe; allocating second data and a second pilot for a second type service to a second block period overlapping with the first block period; and transmitting the first subframe to another communication node. Here, at least one of the second data and the second pilot is allocated to an area to which the first data is allocated.

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.
