Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a transceiver; and
at least one processor coupled to the transceiver,
wherein the at least one processor is configured to:
receive configuration information related to a message A related to a type-2 random access procedure;
transmit the message A comprising a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and
receive, in response to the message A, a message B related to the type-2 random access procedure,
wherein a plurality of PUSCH occasions related to the PUSCH are configured in a frequency domain and a time domain,
wherein the plurality of PUSCH occasions are determined based on the configuration information,
wherein a plurality of PRACH preambles are mapped to at least one PUSCH occasion and at least one demodulation reference signal (DMRS) resource,
wherein the at least one PUSCH occasion is respectively associated with the at least one DMRS resource,
wherein each DMRS resource of the at least one DMRS resource is determined based on a DMRS resource index, and
wherein the DMRS resource index is determined first in an ascending order of a DMRS port index and second in an ascending order of a DMRS sequence index.
