Congestion control for multiple radio access technologies on an unlicensed band

A first user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive, from a second UE via a sidelink channel, an indication of one or more channel occupancy times (COTs) associated with a first radio access technology (RAT) on an unlicensed band;
• calculate a congestion control parameter associated with a second RAT on the unlicensed band, wherein the congestion control parameter is calculated by excluding sub-channels in the one or more COTs;
• and
• use the congestion control parameter to communicate via the unlicensed band.

A method of wireless communication performed by a user equipment (UE), comprising:

• identifying one or more channel occupancy times (COTs) associated with a first radio access technology (RAT) on an unlicensed band;
• calculating a congestion control parameter associated with a second RAT on the unlicensed band, wherein the congestion control parameter is calculated by excluding sub-channels in the one or more COTs;
• and
• using the congestion control parameter to communicate via the unlicensed band.
