Classification: CPC H | IPC H

Claim 9:
10. A base station (BS) for transmitting physical downlink control channel (PDCCH), the BS comprising:
a transceiver; and
at least one processor coupled to the transceiver and configured to:
transmit, to the UE, a configuration of a control resource set (CORESET) including information of a CORESET identifier, information of a number of the CORESET and information related to discrete Fourier transform spreading orthogonal frequency division multiplexing (DFT-S-OFDM) via higher layer signaling, and
transmit the PDCCH based on the configuration of the CORESET,
wherein a size of DFT for the DFT-S-OFDM is determined based on the number of the CORESET.
