Abstract: In an aspect, to perform inter-frequency measurements by a user equipment (UE) in a carrier aggregation mode, the UE receives assistance data identifying one or more reference signal occasions for one or more neighbor cells, receives information identifying one or more subframes during which the one or more neighbor cells do not carry data transmissions, identifies, for a first reference signal occasion of the one or more reference signal occasions, a first subframe of the one or more subframes that overlaps the first reference signal occasion, tunes, during the first subframe, a first active carrier receiver of a plurality of active carrier receivers away from a first frequency on which the first subframe is transmitted to a second frequency on which the first reference signal occasion is transmitted, and measures, by the first active carrier receiver, the first reference signal occasion on the second frequency during the first subframe.

Abstract: Techniques are discussed herein for efficiently providing wireless emergency alerts (WEA) to a mobile device. The techniques include broadcasting a warning message from a base station in a wireless network within a cell for the base station and including an interior cell or exterior cell indication and a geographic area description for an external cell. A receiving mobile device may then display the warning message to a user either unconditionally when an interior cell is indicated or after verifying the mobile device is located within the geographic area for an exterior cell. The wireless network may determine interior versus exterior cell status by determining interior cells to be wholly within the geographic area and exterior cells to be partly within the geographic area.

Abstract: Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.

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: Mobile devices often use orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, physical distance between the mobile device and a signal source for positioning and other environmental factors can influence the signal strength of received signals. Received signals at the mobile device that are stronger may drown out the weaker signals, particularly when two signal sources occupy the same symbol. In traditional OFDM, a signal source transmits the same symbol for each positioning occasion, so a weaker signal may never be detected over a stronger signal, reducing the accuracy of the positioning calculations. Described herein are systems and methods for using a pattern to vary the designated symbol for each signal source in a wireless network so that a weaker signal from a signal source may be detected on at least some of the positioning occasions.

Abstract: Techniques for improving enhanced cell identification (E-CID) positioning are provided. An example of a method for determining a location of a mobile device according to the disclosure includes generating a plurality of receive beams with a mobile device, receiving, with one or more of the plurality of receive beams, a radio beam transmitted from a base station, such that the radio beam includes a beam identification value, and determining a measurement quantity for the radio beam for each of the one or more of the plurality of receive beams.

Abstract: Techniques for supporting location services for a base station such as a home Node B (HNB) and its user equipments (UEs) are disclosed. In an aspect, location services may be supported for a UE by having an HNB inter-work between user plane and control plane location solutions. In another aspect, a location server may be used to support assisted GNSS (A-GNSS) for HNBs and UEs. In one design, a location server receives a positioning request including an identification value from a base station, determines a positioning method based on the identification value, sends a positioning response to the base station based on the positioning method, receives positioning information from the base station, determines the position of the base station based on the positioning information, and stores the position of the base station.

Abstract: Disclosed are methods and systems for broadcasting positioning assistance data (PAD) to subscriber devices in a wireless network. In one aspect, a location server may encode and optionally cipher PAD and transfer the encoded and optionally ciphered PAD to a base station for broadcast in a system information block (SIB) in at least one cell. In an aspect, the PAD may be segmented by the location server or by the base station with each PAD segment broadcast in a separate SIB. Cipher key information for ciphered PAD may be transferred by the location server to a network node and provided to a subscriber device using a mobility management procedure. A subscriber device may receive, optionally decipher and decode PAD in SIBs broadcast by a base station and may use the PAD to assist location of the subscriber device.

Abstract: Disclosed is a method and apparatus for location determination at a mobile device comprising sending positioning capabilities of the mobile device to a location server, where the positioning capabilities comprise an identification of a partial Radio Frequency (RF) band that is contained within a complete RF band. The positioning capabilities indicate that the mobile device can measure the partial RF band but cannot measure the complete RF band. The mobile device may subsequently receive location assistance data from the location server, where the location assistance data comprises configuration information for at least one reference signal (RS) in the partial RF band. The mobile device may then obtain at least one location measurement from the at least one RS based on the configuration information, and sends location information to the location server, where the location information is based on the at least one location measurement.
