Methods and apparatuses for downlink control signaling

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

• receiving configuration information indicative of a first search space and a second search space, wherein the first search space is associated with a first control resource set (CORESET) comprising one or more subband full-duplex (SBFD) symbols and the second search space is associated with a second CORESET comprising one or more non-SBFD symbols;
• monitoring the first search space for physical downlink control channel (PDCCH);
• measuring a cross link interference (CLI) in a carrier associated with the first search space;
• determining that the measured CLI is greater than a threshold CLI;
• stopping monitoring the first search space;
• monitoring the second search space;
• and
• transmitting, to a base station, an indication of high CLI.

A wireless transmit/receive unit (WTRU), comprising:

• a transceiver;
• and
• a processor, wherein the transceiver and the processor are configured to:
• receive configuration information indicative of a first search space and a second search space, wherein the first search space is associated with a first control resource set (CORESET) comprising one or more subband full-duplex (SBFD) symbols and the second search space is associated with a second CORESET comprising one or more non-SBFD symbols;
• monitor the first search space and the second search space for physical downlink control channel (PDCCH);
• measure a cross link interference (CLI) in a carrier associated with the first search space;
• determine that the measured CLI is greater than a threshold CLI;
• stop monitoring the first search space;
