1. A method comprising:
receiving, by a first wireless device, one or more configuration parameters indicating:
a plurality of sidelink carriers associated with a sidelink radio resource control (RRC) connection to a second wireless device;
a discontinuous transmission (DTX) threshold value; and
a channel busy ratio (CBR) threshold value for a sidelink carrier selection procedure;
selecting one or more first sidelink carriers from the plurality of sidelink carriers;
determining:
one or more DTXs on at least one sidelink carrier of the one or more first sidelink carriers; and
a number of the one or more DTXs on one or more second sidelink carriers of the at least one sidelink carriers being equal to the DTX threshold value, wherein a DTX on each sidelink carrier of the one or more first sidelink carriers is based on absence of a physical sidelink feedback channel (PSFCH) reception on the corresponding sidelink carrier;
based on the determining:
triggering the sidelink carrier selection procedure for the sidelink RRC connection; and
transmitting a message comprising a parameter indicating the one or more second sidelink carriers;
selecting, during the triggered sidelink carrier selection procedure and based on a CBR, of a third sidelink carrier from the plurality of sidelink carriers, being below the CBR threshold value, the third sidelink carrier; and
transmitting, to the second wireless device, a sidelink transport block (TB) via the third sidelink carrier.
