1. A method of wireless communication at a user equipment, the method comprising:
decoding first data on a first subchannel of a plurality of subchannels;
calculating a first received signal power associated with a second subchannel of the plurality of subchannels based on an estimate of leakage from the first subchannel to the second subchannel;
designating the second subchannel as unoccupied based on a failure to successfully decode second data on the second subchannel, wherein the designating the second subchannel as unoccupied is further based on the first received signal power associated with the second subchannel being less than a second received signal power associated with the first subchannel; and
transmitting a first transmission via the second subchannel according to a channel busy ratio (CBR) for the user equipment that is based on the designating the second subchannel as unoccupied.
