1. A wireless transmit/receive unit (WTRU), comprising:
a transceiver; and
a processor, wherein the transceiver and the processor are configured to:
perform sensing for a duration of a sensing window using a set of subchannels and a set of slots associated with the sensing window, wherein the sensing window is for partial sensing;
select, based on the performed sensing, resources for sidelink data transmissions by the WTRU;
determine a set of slots for performing channel busy ratio (CBR) measurements based on the set of slots associated with the sensing window;
perform CBR measurements on a sidelink in the determined set of slots and using the set of subchannels associated with the sensing window;
calculate a CBR by calculating a ratio between a determined number of busy subchannels and a total number of subchannels in the set of subchannels associated with the sensing window; and
transmit sidelink data using the selected resources and based on the calculated CBR.
