11. A communication device configured to transmit and receive a signal in a wireless communication system, the communication device comprising:
at least one transceiver;
at least one processor; and
at least one memory operatively coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations comprising:
transmitting synchronization signal blocks (SSBs);
receiving a random access preamble in a specific random access channel occasion (RO) among a plurality of ROs, the plurality of ROs corresponding to a selected SSB among the SSBs;
transmitting, based on the random access preamble, downlink control information (DCI), with cyclic redundancy check (CRC) scrambled by a random access radio network temporary identifier (RA-RNTI), wherein the DCI includes a field that includes partial bits of a frame index that are same as corresponding partial bits of a frame index of the specific RO, and the RA-RNTI is computed based on time and frequency indices of the specific RO except for the partial bits of the frame index; and
transmitting a random access response corresponding to the random access preamble based on the RA-RNTI and the field.
