Abstract: Techniques disclosed herein help a location server identify inaccuracies in a list of neighboring cells provided by the location server by enabling mobile devices to, during an OTDOA session to opportunistically take Reference Signal Time Difference (RSTD) measurements of additional cells not on the neighboring cell list. The mobile device can then provide these RSTD measurements back to the server, which can optimize its algorithm for determining neighboring cells based on these measurements.

Abstract: Disclosed are methods and systems for providing control over a port, such as a port utilizing the User Datagram Protocol, for example, in a mobile device. In a particular implementation, a mobile device user may select to close or otherwise restrict access to the port, which may thus prevent a user external to the cellular communications network from obtaining the user's present location and/or from hindering operations of the mobile device. Upon detection of an event, the port may be reopened, which may thereby permit a cellular communications network to determine an estimate of the mobile device user's location responsive to, for example, the user placing an E911 emergency call.

Abstract: In techniques disclosed allow a user equipment (UE) that receives location assistance data to determine a preferred bandwidth part (BWP) with which reference signals from one or more base stations can be measured for position determination of the UE. The selection of the preferred BWP can be based on a determination of the frequency and bandwidth of reference signals to be transmitted by the one or more base stations over the course of a positioning station. The preferred BWP may be the BWP, of a plurality of candidate BWPs, that allows for a desired number of reference signal measurements to be taken without retuning a transceiver of the UE.

Abstract: Methods and techniques are described for enhancing positioning related protocols in order to indicate when one location session is different from another location session. One or more messages provided in a location session by a location server to a user equipment (UE) may include a session indication, such as a session identifier (ID), where a different session ID is provided for each location session. The session indication may be a new session indicator provided in an initial message in a location session or an end session indicator provided in a final message in a location session. An extra message may be sent by the location server indicating that the location session has ended. A correlation ID provided by a network entity to the location server may be included in messages as the session indication, e.g., where a different correlation ID is provided for each location session.

Abstract: Techniques are provided for network mode selection based on positioning system information blocks (SIBs). An example method for measuring positioning reference signals with a user equipment includes receiving one or more system information blocks containing positioning reference signal information, determining band and frequency information for positioning reference signals based on the one or more system information blocks, determining at least one operational constraint for the user equipment, determining a network mode for the user equipment based at least on the band and frequency information and the at least one operational constraint, and measuring one or more positioning reference signals based at least in part on the network mode.

Abstract: A user equipment (UE) is configured to be connected to multiple wireless networks, including e.g., a 5G New Radio (NR) network and an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN). The UE may assign one of the networks with a higher priority for connection. The UE monitors wireless signal metrics to determine if the priority assignment of the networks should be inverted. The UE may monitor the expected data throughput, e.g., determined based on the availability of carrier aggregation, the carrier aggregation order, the multiple in multiple out (MIMO) order, the available bandwidth, E-UTRAN NR—Dual connectivity (ENDC) availability, or quality metrics of wireless signals from one or both wireless networks. The UE may further dynamically select a carrier subscription as the Default Data Subscription (DDS) based on the metrics as well as whether a wireless network associated with a carrier subscription supports ENDC.

Abstract: Methods and systems for wireless communication are provided. In one example, a mobile device is configured to: obtain beam support information of a plurality of cells; perform measurements of one or more signals at the mobile device based on the beam support information of the plurality of cells to support a location determination operation for the mobile device; and transmit results of the measurements of the one or more signals to at least one of a location server or to a base station to support the location determination operation. The beam support information may include: a number of beams supported at each cell of the plurality of cells, information to identify each beam of the number of beams supported at the each cell, beam width information of the each beam, and/or Positioning reference Signals (PRS) codebook information which encapsulates the beams which are enabled along various elevation and azimuth angles.
