         2 . The one or more non-transitory computer-readable media of  claim 1 , wherein the first-detected path is associated with a line of sight (LoS) path. 
     
     
         3 . The one or more non-transitory computer-readable media of  claim 1 , wherein the first-detected path is based on a channel response. 
     
     
         4 . The one or more non-transitory computer-readable media of  claim 1 , wherein the RSRP measurement is a first RSRP measurement, and the instructions, when executed by the one or more processors, further cause the UE to:
 perform a plurality of RSRP measurements of the PRS; and   include, in the report to the LMF, the plurality of RSRP measurements.   
     
     
         5 . The one or more non-transitory computer-readable media of  claim 1 , having instructions that, when executed by one or more processors, cause a user equipment (UE) to:
 receive, from a location management function (LMF), a message including assistance data, the assistance data including an indication to measure a downlink (DL) reference signal time difference (RSTD).   
     
     
         6 . The one or more non-transitory computer-readable media of  claim 5 , having instructions that, when executed by one or more processors, cause a user equipment (UE) to:
 perform a DL-RSTD measurement based on the message.   
     
     
         7 . The one or more non-transitory computer-readable media of  claim 1 , having instructions that, when executed by one or more processors, cause a user equipment (UE) to:
 measure a power of the first-detected path; and   include, in the report, an indication of a relative power of the power of the first-detected path to the RSRP.   
     
     
         8 . A method for operating a base station, the method comprising:
 performing a reference signal receive power (RSRP) measurement based on a first-detected path of an uplink (UL) sounding reference signal (SRS); and   transmitting a report to a network node based on the RSRP measurement, the report to include the RSRP measurement and an indication that the RSRP measurement was based on a first-detected path of the UL-SRS.   
     
     
         9 . The method of  claim 8 , wherein the first-detected path is associated with a line of sight (LoS) path. 
     
     
         10 . The method of  claim 8 , wherein the first-detected path is based on a channel response. 
     
     
         11 . The method of  claim 8 , further comprising:
 measuring a power of the first-detected path; and   including, in the report, an indication of a relative power of the power of the first-detected path to the RSRP.   
     
     
         12 . The method of  claim 8 , further comprising:
 receiving, from a location management function (LMF), a message including assistance data, the assistance data including an indication to measure an uplink (UL) relative time of arrival (RTOA).   
     
     
         13 . The method of  claim 12 , further comprising:
 performing a UL-RTOA measurement based on the message.   
     
     
         14 . One or more non-transitory computer-readable media having instructions that, when executed by one or more processors, cause a location management function (LMF) to:
 receive, from an entity, a location services request; and   receive, from a user equipment (UE) or a base station (BS), a measurement report including reference single receive power (RSRP) measurements and an indication that the RSRP measurement were based on a first-detected path.   
     
     
         15 . The one or more non-transitory, computer-readable media of  claim 14 , wherein the measurement report includes a location of the UE. 
     
     
         16 . The one or more non-transitory, computer-readable media of  claim 14 , wherein the instructions, when executed by the one or more processors, further cause the LMF to:
 send, to the UE or the BS, assistance data, wherein the RSRP measurement are based on the assistance data.   
     
     
         17 . The one or more non-transitory, computer-readable media of  claim 14 , wherein the instructions, when executed by the one or more processors, further cause the LMF to:
 send, to the UE, assistance data including an indication configuring the UE to measure a downlink (DL) reference signal time difference (RSTD).   
     
     
         18 . The one or more non-transitory, computer-readable media of  claim 14 , wherein the instructions, when executed by the one or more processors, further cause the LMF to:
