Sidelink resource selection schemes for coexistence of multiple radio access technologies

A method of wireless communications at a user equipment (UE), comprising:

• receiving, for a wireless channel associated with coexistence of first sidelink communications associated with a first radio access technology (RAT) and second sidelink communications associated with a second RAT, an indication of a first set of resources that are available for communications associated with the first RAT and communications associated with the second RAT;
• initializing, for at least transmitting one or more sidelink messages using the first RAT, a second set of resources, the second set of resources comprising a subset of the first set of resources, wherein the second set of resources is based at least in part on usage information for the second RAT on the wireless channel;
• selecting, for transmitting the one or more sidelink messages using the first RAT, one or more resources from the second set of resources;
• and
• transmitting the one or more sidelink messages using the first RAT and the one or more resources from the second set of resources.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor to:

• receive, for a wireless channel associated with coexistence of first sidelink communications associated with a first radio access technology (RAT) and second sidelink communications associated with a second RAT, an indication of a first set of resources that are available for communications associated with the first RAT and communications associated with the second RAT;
• initialize, for at least transmitting one or more sidelink messages using the first RAT, a second set of resources, the second set of resources comprising a subset of the first set of resources, wherein the second set of resources is based at least in part on usage information for the second RAT on the wireless channel;
• select, for transmitting the one or more sidelink messages using the first RAT, one or more resources from the second set of resources;
• and
• transmit the one or more sidelink messages using the first RAT and the one or more resources from the second set of resources.
