    Abstract: An operation method of a relay in a mobile communication system may comprise the steps of: receiving information relating to a backhaul reception beam and/or a backhaul transmission beam from a base station; receiving information relating to an access link transmission beam and/or an access link reception beam from the base station or obtaining information relating to an access link transmission beam and/or an access link reception beam from the information relating to the backhaul reception beam and/or backhaul transmission beam; communicating with the base station by using the backhaul reception beam and/or the backhaul transmission beam formed using the information relating to the backhaul reception beam and/or backhaul transmission beam; and communicating with a terminal by using the access link transmission beam and/or the access link reception beam formed using the information relating to the access link transmission beam and/or access link reception beam.

    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.
