Abstract
Techniques are provided for transmitting Positioning Reference Signals (PRSs) in cells supporting two different Radio Access Technologies (RATs), where the two RATs (e.g. 4G LTE and 5G NR) employ dynamic spectrum sharing. To avoid interference between the PRSs and between the two RATs, the PRSs may be time aligned to the same set of PRS positioning occasions, and may be assigned orthogonal characteristics such as different muting patterns, orthogonal code sequences, different frequency shifts or different frequency hopping. UEs supporting both RATs may be enabled to measure PRSs for both RATs. UEs supporting only one RAT (e.g. 4G LTE) may be enabled to measure PRSs for just this RAT. A location server such as an LMF, E-SMLC or SLP may provide assistance data to UEs, and request measurements from UEs, for PRSs in one or both RATs.
