User equipments, base stations and methods

A base station comprising:

• a higher layer processor configured to send a first radio resource control (RRC) configuration including first information for indicating a control resource set (CORESET) duration, and to send a second RRC configuration including second information for indicating physical downlink control channel (PDCCH) monitoring symbols, to send third information for indicating PDCCH monitoring periodicity k, and to send fourth information for indicating PDCCH monitoring offset o;
• and
• transmitting circuitry configured to transmit a PDCCH, based on the first information, the second information, the third information, and the fourth information;
• wherein 0≤o<k, the CORESET duration is set to a value larger than 1,
• the second information expresses a PDCCH monitoring pattern within a slot and is bitmap information that includes 14 bits,
• each bit of the bitmap information corresponds to a respective OFDM symbol #0 to #13 in the slot,
• the bit of which value is set to 1 indicates a start of a PDCCH monitoring occasion,
• the bitmap information is set such that two adjacent PDCCH monitoring occasions in the slot do not overlap with each other, and
• the two adjacent PDCCH monitoring occasions in the slot are based on a single CORESET duration parameter and a single resource block frequency-domain parameter.

A method for a user equipment (UE), the method comprising:
