Low-power positioning reference signal for low-power receiver

An apparatus for wireless communication at a first network node, comprising:

• a memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• transmit, to a second radio at a user equipment (UE), a set of low-power (LP) positioning reference signals (LP-PRSs);
• and
• transmit, to the second radio at the UE, an LP wake-up signal (LP-WUS) comprising an indication to measure the set of LP-PRSs.

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

• receiving, via a first radio, assistance data comprising a configuration of a set of low-power (LP) positioning reference signals (LP-PRSs);
• receiving, via a second radio, the set of LP-PRSs, wherein the second radio has a lower power consumption than the first radio;
• and
• measuring the set of LP-PRSs based on the configuration of the set of LP-PRSs.
