Joint sidelink and uplink/downlink positioning

A user equipment (UE) comprising:

• means for identifying a processing conflict for an exchange of a first UE-to-UE location reference signal and an exchange of a first radio-network-interface signal;
• means for determining a priority of the exchange of the first UE-to-UE location reference signal and the exchange of the first radio-network-interface signal, wherein the means for determining the priority comprise means for determining the priority from a priority list indicating relative priority of at least uplink with control information, uplink without control information, and UE-to-UE with location reference signal content based on the exchange of the first UE-to-UE location reference signal being reception of the first UE-to-UE location reference signal and exchange of the first radio-network-interface signal being transmission of an uplink signal;
• and
• means for exchanging one of the first UE-to-UE location reference signal or the first radio-network-interface signal according to the priority.

A method of joint signal exchange over an interface between user equipments and over a radio network interface, the method comprising:

• identifying a processing conflict for a user equipment (UE) for an exchange of a first UE-to-UE location reference signal and an exchange of a first radio-network-interface signal;
• determining a priority of the exchange of the first UE-to-UE location reference signal and the exchange of the first radio-network-interface signal, wherein determining the priority comprises determining the priority from a priority list indicating relative priority of at least uplink with control information, uplink without control information, and UE-to-UE with location reference signal content based on the exchange of the first UE-to-UE location reference signal being reception of the first UE-to-UE location reference signal and exchange of the first radio-network-interface signal being transmission of an uplink signal;
• and
• exchanging one of the first UE-to-UE location reference signal or the first radio-network-interface signal according to the priority.

A non-transitory, processor-readable storage medium comprising processor-readable instructions configured to cause a processor of a user equipment (UE), in order to exchange signals over an interface between user equipments and over a radio network interface, to:

• identify a processing conflict for the UE for an exchange of a first UE-to-UE location reference signal and an exchange of a first radio-network-interface signal;
• determine a priority of the exchange of the first UE-to-UE location reference signal and the exchange of the first radio-network-interface signal, wherein the instructions configured to cause the processor to determine the priority comprise instructions configured to cause the processor to determine the priority from a priority list indicating relative priority of at least uplink with control information, uplink without control information, and UE-to-UE with location reference signal content based on the exchange of the first UE-to-UE location reference signal being reception of the first UE-to-UE location reference signal and exchange of the first radio-network-interface signal being transmission of an uplink signal;
• and
• exchange one of the first UE-to-UE location reference signal or the first radio-network-interface signal according to the priority.
