Apparatus, method, and computer program for scheduling transmissions

A method comprising:

• sensing at least one beam;
• initiating a channel occupancy time based on the sensing;
• transmitting at least one first downlink transmission on the at least one beam during the channel occupancy time, wherein the at least one first downlink transmission on the at least one beam triggers at least one first uplink transmission on the at least one beam during the channel occupancy time;
• receiving the at least one first uplink transmission on the at least one beam during the channel occupancy time;
• determining interference condition on the at least one beam based on the at least one first uplink transmission;
• and
• scheduling at least one second downlink transmission or at least one second uplink transmission on the at least one beam with restriction during a rest of the channel occupancy time when the interference condition meets at least one threshold requirement,
• wherein the restriction restricts a number and/or a duration of the at least one second downlink transmission or a number and/or a duration of the at least one second uplink transmission.

A non-transitory computer program product comprising computer executable instructions which when executed on one or more processors cause an apparatus at least to:

• sense at least one beam;
• initiate a channel occupancy time based on the sensing;
• transmit at least one first downlink transmission on the at least one beam during the channel occupancy time, wherein the at least one first downlink transmission on the at least one beam triggers at least one first uplink transmission on the at least one beam during the channel occupancy time;
• receive the at least one first uplink transmission on the at least one beam during the channel occupancy time;
• determine interference condition on the at least one beam based on the at least one first uplink transmission;
• and
• schedule at least one second downlink transmission or at least one second uplink transmission on the at least one beam with restriction during a rest of the channel occupancy time when the interference condition meets at least one threshold requirement,
• wherein the restriction restricts a number and/or a duration of the at least one second downlink transmission or a number and/or a duration of the at least one second uplink transmission.
