1. A method comprising:
transmitting a preamble for an access procedure;
receiving a response with respect to the preamble;
transmitting a message requesting higher layer connection based on the response;
receiving information indicating setup of the higher layer connection;
receiving configuration information related to a control resource set based on the higher layer connection;
receiving a data channel configuration that includes a first scrambling identifier and a second scrambling identifier;
receiving (i) a first control channel scheduling a first data channel and (ii) the first data channel; and
receiving (i) a second control channel scheduling a second data channel and (ii) the second data channel,
wherein a first control resource set (CORESET) and a second CORESET, which are related to different CORESET pool indexes, are configured based on the configuration information,
wherein the first scrambling identifier is related to a first CORESET pool index for the first CORESET, and the second scrambling identifier is related to a second CORESET pool index for the second CORESET in a same bandwidth part (BWP) as the first CORESET,
wherein a scrambling sequence generator related to each data channel is initialized with cinit=nRNTI·215+q·214+nID,
wherein the nRNTI is based on a Radio Network Temporary Identifier (RNTI) associated with the each data channel, the q is a value based on a codeword related to the each data channel, and the nID is different from a cell identity,
wherein, based on the first data channel being scheduled based on the first CORESET with the first CORESET pool index, the nip equals the first scrambling identifier, and
wherein, based on the second data channel being scheduled based on the second CORESET with the second CORESET pool index, the nip equals the second scrambling identifier.
