Abstract: Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, a message is prepared and transmitted with a message segment including a version of a protocol used to encode the message and a compatibility level associated with inter-operable protocol versions, wherein different compatibility levels indicate non-compatibility between protocol versions. In another aspect, a message is received with a message segment including a version of a protocol used to encode the message and a compatibility level associated with inter-operable protocol versions, wherein different compatibility levels indicate non-compatibility between protocol versions. The compatibility level included in the received message is compared to an internal compatibility level and a response message is prepared and transmitted with a message segment including the internal compatibility level.

Abstract: A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity.

Abstract translation: 与无线电接入网络（RAN）通信的用户设备（UE）向网络实体（例如，MSC / SGSN）发送用于向客户端实体定期报告UE位置的请求。 在请求被批准之后，MSC / SGSN向RAN发送信令以发起针对UE的周期性位置报告。 RAN可以请求定位中心（例如，SAS）向UE发送辅助数据。 RAN可以协调和控制周期性位置报告，或者可以将控制传递给定位中心。 对于每个位置报告，UE向RAN发送位置信息（例如由UE进行的测量或由UE计算的位置估计）。 如果UE发送测量，则SAS计算位置估计。 RAN然后将UE的位置估计发送给MSC / SGSN，MSC / SGSN将位置估计转发给客户实体。

Abstract: Techniques disclosed herein provide for enhanced LTE Positioning Protocol (LPP) Reliable Transport where the receiver of an LPP message sends a non-piggybacked acknowledgement. An example method for executing on a mobile device a protocol session with a location server includes sending a first protocol session message associated with a first protocol session to the location server, entering a wait-for-acknowledgement state in which uplink transmissions from the mobile device to the location server are suspended while waiting for an acknowledgement from the location server in response to the first protocol session message, receiving a second protocol session message associated with a second protocol session which is not an acknowledgement to the first protocol session message but includes information requested in the first protocol session message; exiting the wait-for-acknowledgement state responsive to receiving the second protocol session message; and performing an action using the information received in the second protocol session message.

Abstract: Disclosed are methods and systems for supporting positioning operations in a cellular communication network including locating a mobile device in response to an emergency event. In one particular implementation, a first position fix may be provided quickly by a mobile device and may be followed by a second, more accurate, position fix at a later time. In particular implementations, the first and second position fixes may be provided using the 3GPP Long Term Evolution (LTE) Positioning Protocol (LPP) as part of a single LPP transaction and may further be provided using a user plane or control plane location solution.

Abstract: A method and apparatus for broadcasting short interframe space information to aid in determining a round trip time are provided. The round trip time is used as an aid in locating nodes within a WiFi or WLAN network. The method begins with capturing a time of transmission of a frame by a transmitting station. The receiving station then captures the time of arrival of the frame just sent by the transmitting station. The receiving station replies with a received frame message and the time of departure is captured. The transmitting station then captures the time of arrival of the received frame message. The captured arrival and departure times of the frame and the received frame message allow the round trip time to be computed. The RTT may then be included as part of a network message.

Abstract: Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.

Abstract: A user equipment (UE) receives reference signal resource configuration for transmitting reference signals for positioning from, e.g., a location server. The UE transmits or attempts to transmit reference signals for positioning to one or more transmission-reception points, such as a gNB. The UE may, however, may be unable to transmit reference signals in accordance with the reference signal resource configuration. For example, the UE may be unable to transmit the reference signals or may transmit the reference signals with lower power or a different spatial relation than configured. The UE may provide a reference signal transmission report indicating that the reference signals were not transmitted according to the reference signal resource configuration. The reference signal transmission report may indicate how the reference signal transmission differs from the reference signal resource configuration and may indicate the reasons that the reference signal transmission differs from the reference signal resource configuration.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits, at a first time during a measurement window for positioning purposes, a first uplink reference signal in accordance with a first timing adjustment parameter, wherein the first time is offset from a downlink frame time of a base station by an amount of the first timing adjustment parameter, determines whether to use a second timing adjustment parameter, transmits, in response to the determination to use the second timing adjustment parameter, at a second time during the measurement window, a second uplink reference signal in accordance with a second timing adjustment parameter, wherein the second time is offset from the downlink frame time of the base station by an amount of the second timing adjustment parameter, and transmits a report indicating that the second timing adjustment parameter has been applied to at least the second uplink reference signal.
