Sidelink resource reservation in a shared band

An apparatus for wireless communication of a user equipment (UE) operating using a first radio access technology, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a sidelink resource pool of a shared resource band and a parameter of a competition level metric for measuring communication activity in the shared resource band, the shared resource band associated with communication by the first radio access technology and a second radio access technology that differs from the first radio access technology;
• monitor, in accordance with the parameter of the competition level metric, at least one resource of the sidelink resource pool to determine the competition level metric for the shared resource band;
• and
• transmit one or more reservations for reserving one or more resources of the sidelink resource pool based at least on part on the competition level metric.
