Measurement gap (MG) consideration of sidelink (SL)-assisted positioning

A method of measurement gap (MG) configuration of a first User Equipment (UE) for Sidelink Positioning Reference Signal (SL-PRS) measurements, the method comprising:

• sending, from the first UE to a network node:
• an MG configuration report indicative of a first MG configuration;
• subsequent to the sending, receiving a second MG configuration determined based on the first MG configuration at the first UE and an initial MG configuration for determining a downlink PRS (DL-PRS) measurement, the second MG configuration scheduling an MG for a period of time during which an SL-PRS is to be measured;
• and
• measuring the SL-PRS in accordance with the second MG configuration.

A device for providing measurement gap (MG) configuration of a first User Equipment (UE) for Sidelink Positioning Reference Signal (SL-PRS) measurements, the device comprising:

• a communications interface;
• a memory;
• and
• one or more processing units communicatively coupled with the communications interface and the memory, the one or more processing units configured to:
• determine an initial MG configuration of the first UE regarding a first Positioning Reference Signal (PRS) measurement to be made by the first UE, the first PRS measurement comprising an SL-PRS measurement, wherein the initial MG configuration is configured for determining a downlink PRS (DL-PRS) measurement;
• receive, from the first UE, an MG configuration report indicative of a PRS processing capability of the first UE;
• determine information regarding a second PRS measurement;
• determine a SL-PRS MG configuration, wherein:
• the SL-PRS MG configuration schedules at least one MG for at least one period of time during which the first UE is to make the first PRS measurement, and
• the SL-PRS MG configuration is based at least in part on the initial MG configuration, the PRS processing capability of the first UE, and the information regarding the second PRS measurement;
• and
• send, with the communications interface, the MG configuration to the first UE.

A first User Equipment (UE) configured to obtain measurement gap (MG) configuration for Sidelink Positioning Reference Signal (SL-PRS) measurements, the first UE comprising:

• a wireless communication interface;
• a memory;
• and
• one or more processing units communicatively coupled with the wireless communication interface and the memory, the one or more processing units configured to:
• send to a network node via the wireless communication interface:
• an MG configuration report indicative of a first MG configuration;
• subsequent to the sending, receive a second MG configuration determined based on the first MG configuration and an initial MG configuration for determining a downlink PRS (DL-PRS) measurement via the wireless communication interface, the second MG configuration scheduling an MG for a period of time during which an SL-PRS is to be measured;
• and
• measure the SL-PRS in accordance with the second MG configuration.
