5.7.6 Sidelink Reference Signal and Measurements for Positioning

Taught in 2. The six working groups and the line between them (TSG RAN — the group that specifies the radio, overview), 2. The six groups, and what each one worries about (TSG RAN — the group that specifies the radio, quick start).

The Sidelink Positioning Reference Signal (SL-PRS) is defined to facilitate Ranging/Sidelink positioning methods, such as SL-TOA, SL-TDOA, SL-RTT, SL-AoA, through the following set of measurements SL-PRS RSRP, RSRPP, RTOA, RSTD, Rx-Tx timing difference and AoA as described in TS 38.305 [42].
