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: A signal transmission method and an apparatus. The method includes: a location management device receives first SRS resource configuration information from a serving cell and/or a neighboring cell. The location management device sends second SRS resource configuration information to a terminal device, where the second SRS resource configuration information includes third SRS resource configuration information and a downlink reference signal associated with an SRS resource indicated by the third SRS resource configuration information, and the third SRS resource configuration information is a part or all of the first SRS resource configuration information. The location management device configures the SRS resource for the terminal device, so that the SRS resource can be associated with the downlink reference signal. This helps the terminal device obtain information about a transmission beam for sending an SRS, and therefore SRS receiving efficiency of the cell can be improved to some extent.

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: Embodiments are provided to serve user equipments (UEs) that experience, for example persistently, inter-transmission point group (TPG) interference in a wireless or cellular network. The embodiments include steps to serve edge UEs (EUs) such as persistent EUs (PEUs) using a set of transmission points (TPs) in one or more TPGs. The selected set of TPs used for serving the EUs or PEUs are dynamically determined based on a UE-centric metric. The metric involves the PEUs and surrounding UEs. The UE-centric metric is used to partition the network to multiple TPG sets. For each one of multiple assigned resource units (RUs), a TPG set that maximizes or improves a network-wide utility is used for scheduling transmissions. Further, for each RU, the UEs are associated with an optimized or improved TPG in the used TPG set.
