Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a requesting entity, a request for information relating to a channel condition of the UE. The requesting entity may comprise a base station or a location server, for example. The UE may determine information relating to the channel condition of the UE. The UE may send, to the requesting entity, the information relating to the channel condition of the UE. In some aspects, the UE may receive location assistance data from the requesting entity along with a request to perform a location measurement; the UE may perform the location measurement and send location information to the requesting entity. The location information may comprise a location measurement result, the UE's estimate of its own location, or both.

Abstract: Certain aspects of the present disclosure provide techniques for performing a public land mobile network (PLMN) selection procedure based on allowed PLMN(s) in a particular country of a user equipment (UE). An example method generally includes determining a country in which the UE is located, creating a list of available PLMNs, that are allowed to be selected in the country in which the UE is located, for access to a non-terrestrial network (NTN), and performing a PLMN selection procedure for access to the NTN based on the list of available PLMNs and the country in which the UE is located.

Abstract: Satellite access to a public land mobile network (PLMN) with a Fifth Generation (5G) core network (5GCN) is supported by a serving satellite NodeB (gNB). The gNB determines or verifies a country in which a user equipment (UE) is located to ensure that the UE is located in the same country as the 5GCN. The gNB receives assistance data from a location server and receives UE measurements of DL signals from a plurality of satellites, e.g., GNSS satellites and/or communication satellites. The assistance data may be solicited or unsolicited by the gNB. The gNB uses the UE measurements and assistance data to determine a location and country of the UE. The gNB allows access by the UE to the 5GCN when the country matches a country of the 5GCN and may provide the 5GCN with an indication of whether the country of the UE was verified.

Abstract: Methods and techniques are described for efficiently supporting periodic and triggered location services for a user equipment (UE) in a Fifth Generation wireless network. A serving core network (CN) node, such as an AMF, receives a request for periodic or triggered location for the UE from another CN entity, such as a GMLC, and transfers the request to a location server, such as an LMF, which initiates and establishes the periodic and triggered location session with the UE. The serving CN node then releases all resources for the location request. The UE monitors for periodic or trigger events and reports each event to a location server which forwards an event report, optionally containing a UE location, to an external client via a CN entity, such as GMLC. The event reporting can be efficient because a serving CN node is not materially involved.

Abstract: A user equipment (UE) and a Secure User Plane Location (SUPL) Location Platform (SLP) support a SUPL positioning session for at least one uplink or uplink-downlink position method, such as uplink Angle of Arrival or multi-Round Trip Time. To support SUPL positioning for uplink or uplink-downlink position methods, the UE provides an identifier for a serving Access and Mobility Management Function (AMF) and an identifier for the UE to the SLP in a SUPL message. The SLP may exchange positioning messages with a serving base station for the UE using the identifier for the serving AMF and the identifier for the UE. The exchange of positioning messages may enable the SLP to request the serving base station to instigate transmission of uplink positioning reference signals by the UE which may be a key enabler for an uplink or uplink-downlink position method.

Abstract: An external client requests the location of a UE using control plane signaling. The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay.

Abstract: The angle of departure (AOD) of directed beams, e.g., beamformed beams, transmitted by one or more base stations, such as a gNB, and the angle of arrival (AOA) of the directed beams received by a UE may be used to improve positioning accuracy by identifying Line Of Sight (LOS) beams and multi-path beams. The differential AOA (DAOA) of a directed beam pair may compared to the differential AOD (DAOD) of the directed beam pair. Matching DAOA and DAOD may be used as an indication that the directed beams in the beam pair are LOS with the UE, whereas a mis-match indicates one or both of the directed beams are multi-path. The location of the UE may be estimated using the measurement information, e.g., AOA, RTT, RSTD, etc., obtained from LOS directed beams.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

Abstract: Disclosed are methods for aiding a mobile device in the acquisition of positioning reference signals (PRSs) transmitted in a cellular network in support of OTDOA positioning. In one implementation, a mobile device receives an offset parameter from a location server indicative of a difference in timing between transmission of a first PRS positioning occasion for a reference cell and transmission of a second PRS positioning occasion for a neighboring cell that supports multiple PRS configurations, where the second PRS positioning occasion is for a PRS configuration with a longest periodicity. The mobile device may determine an expected timing of PRS positioning occasions for other PRS configurations for the neighboring cell based on the offset parameter and may measure a Reference Signal Time Difference for the neighboring cell using the expected timing.

Abstract: Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.
