Abstract: Methods and devices for assigning sounding reference signals (SRS) resources to UEs in a wireless communication network are provided. Configuration information is sent to a UE, the configuration information pertaining to a first sequence identifier (ID) to be used by the UE to generate a plurality of SRS sequences to be sent by the UE as at least part of a first SRS. Each SRS sequence of the plurality of SRS sequences is a function of a respective SRS sequence root that is a function of the first sequence ID. The first sequence ID may be a UE-specific sequence ID that is a function of a UE-specific ID associated with the UE, such as a Cell-Radio Network Temporary Identifier (C-RNTI).

Abstract: An embodiment method includes identifying a plurality of VTP configurations representing allocations of TPs among a plurality of VTPs each having at least one TP. Potential serving VTPs are then identified for a selected UE in a plurality of UEs according to at least one UE centric criterion. The potential serving VTPs are selected for each of the plurality of VTP configurations. A UE measurement set is then scheduled for the potential serving VTPs for a scheduled channel resource according to measurement parameters. The method further includes selecting a serving VTP configuration from the plurality of VTP configurations according to UE measurement feedback from the selected UE.

Abstract: Methods and apparatuses are described for configuring a downlink (DL) reference signal (RS) for an electronic device (ED). Configuration information associated with the DL RS is received in a first communication from a location management function (LMF) via LTE positioning protocol (LPP). In a communication from a serving cell via radio resource control (RRC), an identifier (ID) of the DL RS and a cell ID of a cell that originates the DL RS are received. The configuration information received in the first communication also includes the ID of the DL RS and the cell ID. A sounding reference signal (SRS) is transmitted to the cell identified by the cell ID, according to path loss (PL) information or spatial domain transmission filter (TF) information associated with the DL RS.
