    Abstract: An operation method of a terminal in a mobile communication system includes receiving information indicating a first scheduling region map consisting of a plurality of resource regions from a base station, the information indicating the first scheduling region map including information indicating the plurality of resource regions included in the first scheduling region map; receiving first resource allocation information indicating a first resource region allocated to the terminal among the plurality of resource regions included in the first scheduling region map from the base station; receiving a first reference signal (RS) from the base station through the first resource region; generating first channel state information (CSI) for the first resource region based on the first RS; and transmitting the first CSI to the base station.

    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.

    IPC: H04L5/00

    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.
