In an exemplary method, a base station may determine a first control resource set (coreset) of time and frequency resources within a control region of system bandwidth, to transmit a physical downlink control channel (PDCCH) to a user equipment (UE) and transmit the PDCCH to the UE as a single caner waveform via the first coreset of time and frequency resources.
