Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 22:
23. An apparatus for wireless communication, comprising:
means for identifying one or more channel occupancy times (COTs) associated with a first radio access technology (RAT) on an unlicensed band;
means for 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
means for using the congestion control parameter to communicate via the unlicensed band,
wherein the means for identifying the one or more COTs comprises:
means for identifying a start of a COT based at least in part on detecting a preamble of a packet associated with the first RAT;
means for detecting a first energy level associated with the unlicensed band at a first time associated with the preamble;
means for 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
means for 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.
