Control Signalling for Transmission in Unlicensed Frequency Spectrum

A method performed by a wireless device configured for use in a wireless communication system, the method comprising:

• monitoring for control signaling indicating that the wireless device will be scheduled to transmit or receive within a channel occupancy time (COT) period, wherein the control signaling comprises an indication of one or more wireless devices that will be scheduled within the COT period;
• determining, based on the indication of the control signaling, whether the wireless device will be scheduled within the COT period;
• and
• monitoring or not monitoring a dedicated control channel during the COT period for a scheduling grant or assignment indicating scheduling of the wireless device according to said determining.

A wireless device configured for use in a wireless communication system, the wireless device comprising:

• communication circuitry;
• and
• processing circuitry configured to:
• monitor for control signaling indicating that the wireless device will be scheduled to transmit or receive within a channel occupancy time (COT) period, wherein the control signaling comprises an indication of one or more wireless devices that will be scheduled within the COT period;
• determine, based on the indication of the control signaling, whether the wireless device will be scheduled within the COT period;
• and
• monitor or not monitor a dedicated control channel during the COT period for a scheduling grant or assignment indicating scheduling of the wireless device according to said determining.

A radio network node configured for use in a wireless communication system, the radio network node comprising:

• communication circuitry;
• and
• processing circuitry configured to:
• transmit control signaling indicating that a wireless device will be scheduled to transmit or receive within a channel occupancy time (COT) period, wherein the control signaling comprises an indication of one or more wireless devices that will be scheduled within the COT period;
• and
• transmit a scheduling grant or assignment indicating scheduling of the wireless device on a dedicated control channel during the COT period.
