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.
