Original Abstract Submitted
Disclosed are techniques for wireless positioning. In an aspect, a first network node receives, from a second network node, a positioning reference signal having a first reception time at the first network node, receives, from a first user equipment (UE), a first uplink positioning reference signal having a second reception time at the first network node, receives, from a second UE, a second uplink positioning reference signal having a third reception time at the first network node, and enables a first reference signal time difference (RSTD) measurement to be calculated for the first UE and a second RSTD measurement to be calculated for the second UE based on the first reception time, the second reception time, the third reception time, and other measurements.
