Classification: CPC H | IPC H

Claim 12:
13. 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,
wherein the identifying the one or more COTs comprises:
identifying a start of a COT based at least in part on detecting a preamble of a packet associated with the first RAT;
detecting a first energy level associated with the unlicensed band at a first time associated with the preamble;
determining that a difference between the first energy level and a second energy level, detected at a second time after the first time, satisfies a threshold; and
identifying an end of the COT based at least in part on determining that the difference between the first energy level and the second energy level satisfies the threshold.
