• and
• map the generated DMRS sequence onto a configured control resource set (CORESET) starting from the PRB of the lowest frequency and mapping to resources in units of PRBs in an increasing frequency order.

An apparatus for a User Equipment (UE), comprising:

• processing circuitry configured to:
• acquire information of control resource configuration associated with the UE, wherein the control resource configuration comprising one or more identifiers;
• acquire information of search space configuration of the UE which is associated with the control resource configuration, wherein the search space information includes a field indicating a first identifier of the one or more identifiers applied for determining at least one control resource candidate for the search space, and a field indicating a second identifier of the one or more identifiers applied for scrambling initialization of the at least one control resource candidate of the search space;
• determine the at least one control resource candidate based on the first identifier;
• determine the scrambling initialization for the at least one control resource candidate of the search space based on the second identifier;

• encode the interleaved information block with Polar codes;
• and
• transmit the encoded information block via the RF interface for decoding at UE side.

An apparatus for a User Equipment (UE), comprising:

• a Radio Frequency (RF) interface;
• and
• processing circuitry configured to:

• and
• stop decoding of the remaining portion of the information block after the estimate of the part of information block is obtained.
