Sidelink resource selection based on an exclusion of sidelink feedback channel slots

A method of wireless communication performed by a first user equipment (UE), comprising:

• receiving, by a first radio access technology (RAT) sidelink module of the first UE from a second RAT sidelink module of the first UE, second RAT sidelink reservation information indicating a reference signal received power (RSRP) value associated with reservation information of a second UE operating on a second RAT;
• performing, using the first RAT sidelink module, a first RAT sidelink resource selection, to exclude or include one or more single slot resources in a non-first-RAT physical sidelink feedback channel (PSFCH) slot or in a first RAT PSFCH slot, based at least in part on the RSRP value indicated in relation to:
• a first RSRP threshold when the one or more single slot resources are in the non-first-RAT-PSFCH slot, or
• a second RSRP threshold when the one or more single slot resources are in the first RAT PSFCH slot,
• wherein performing the first RAT sidelink resource selection comprises:
• determining, based at least in part on the RSRP value indicated in the second RAT sidelink reservation information, that the second RAT reservation collides with the one or more single slot resources in the first RAT PSFCH slot, and
• refraining from excluding the one or more single slot resources in the first RAT PSFCH slot based at least in part on the second RAT reservation being for a transmission from the second RAT sidelink module;
• and
• transmitting, by the first RAT sidelink module and to a third UE, a first RAT sidelink transmission based at least in part on the first RAT sidelink resource selection.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a first user equipment (UE), cause the first UE to:
• receive, by a first radio access technology (RAT) sidelink module of the first UE from a second RAT sidelink module of the first UE, second RAT sidelink reservation information indicating a reference signal received power (RSRP) value associated with reservation information of a second UE operating on a second RAT;
• perform, using the first RAT sidelink module, a first RAT sidelink resource selection, to exclude or include one or more single slot resources in a non-first-RAT physical sidelink feedback channel (PSFCH) slot or in a first RAT PSFCH slot, based at least in part on the RSRP value in relation to:
• a first RSRP threshold associated with the second RAT reservation when the one or more single slot resources are in the non-first-RAT-PSFCH slot, or
• a second RSRP threshold when the one or more single slot resources are in the first RAT PSFCH slot,
• wherein, to perform the first RAT sidelink resource selection, the one or more processors are configured to:
• determine, based at least in part on the RSRP value indicated in the second RAT sidelink reservation information, that the second RAT reservation collides with the one or more single slot resources in the first RAT PSFCH slot, and
• refrain from excluding the one or more single slot resources in the first RAT PSFCH slot based at least in part on the second RAT reservation being for a transmission from the second RAT sidelink module;
• and
• transmit, by the first RAT sidelink module and to a second UE, a first RAT sidelink transmission based at least in part on the first RAT sidelink resource selection.

A first apparatus for wireless communication, comprising:

• means for receiving, by a first radio access technology (RAT) sidelink module of the first apparatus from a second RAT sidelink module of the first apparatus, second RAT sidelink reservation information indicating a reference signal received power (RSRP) value associated with reservation information of a second apparatus operating on a second RAT;
• means for performing, using the first RAT sidelink module, a first RAT sidelink resource selection, to exclude or include one or more single slot resources in a non-first-RAT physical sidelink feedback channel (PSFCH) slot or in a first RAT PSFCH slot, based at least in part on the RSRP value in relation to:
• a first RSRP threshold when the one or more single slot resources are in the non-first-RAT-PSFCH slot, or
• a second RSRP threshold when the one or more single slot resources are in the first RAT PSFCH slot using the second RSRP threshold,
• wherein the means for performing the first RAT sidelink resource selection comprises:
• means for determining, based at least in part on the RSRP value indicated in the second RAT sidelink reservation information, that the second RAT reservation collides with the one or more single slot resources in the first RAT PSFCH slot, and
• means for refraining from excluding the one or more single slot resources in the first RAT PSFCH slot based at least in part on the second RAT reservation being for a transmission from the second RAT sidelink module;
• and
• means for transmitting, by the first RAT sidelink module and to a second apparatus, a first RAT sidelink transmission based at least in part on the first RAT sidelink resource selection.
