    Abstract: A method of a terminal may include: receiving, from a base station, at least one SSB belonging to a first layer; receiving, from the base station, at least one SSB belonging to a second layer; determining valid SSB(s) from among the at least one SSB belonging to the first layer and the at least one SSB belonging to the second layer; selecting at least one first SSB belonging to a layer having a higher priority among the first layer and the second layer from among the valid SSB(s); and reporting the selected first SSB to the base station, and using a beam used for receiving the first SSB to perform an initial access procedure for communications with the base station, wherein each SSB includes at least one of a synchronization signal or a broadcast channel.

    Abstract: An operation method of a terminal may comprise receiving information on one CG configuration for uplink transmission from a base station; obtaining common time domain resource allocation information for combinations of RB sets based on the information on the one CG configuration; obtaining frequency domain resource allocation information for each of the combinations of the RB sets based on the information on the one CG configuration; determining a number of PRBs to which an uplink channel is mapped based on the frequency domain resource allocation information corresponding to one combination of the combinations; determining a TBS based on the common time domain resource allocation information and the number of PRBs; and transmitting a TB having the TBS to the base station within the one combination through the uplink channel according to the common time domain resource allocation information and the frequency domain resource allocation information.
