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, an integrated access and backhaul (IAB) node sets a downlink transmission timing of the IAB node relative to a downlink reception timing of the IAB node based on a first set of values for a set of timing parameters, receives, from a parent IAB node of the IAB node, a second set of values for the set of timing parameters, and transmits, to a positioning entity, a report indicating a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a location server, identifiers of a set of transmission-reception points (TRPs), the set of TRPs including a first reference TRP and a plurality of neighboring TRPs, receives a configuration to report reference signal time difference (RSTD) measurements for the plurality of neighboring TRPs with respect to a receive time of a reference signal from the first reference TRP and UE reception-to-transmission (UE Rx-Tx) measurements for a second reference TRP and the plurality of neighboring TRPs, and transmits, to the location server, based on one or more of a plurality of conditions being satisfied, a single UE Rx-Tx measurement for the second reference TRP and the RSTD measurements for the plurality of neighboring TRPs with respect to the receive time of the reference signal from the first reference TRP.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives at least one of a first type of sounding reference signal (SRS) configuration or a second type of SRS configuration, wherein the first type of SRS configuration is based on a first set of available configurations for SRS received over a first higher layer protocol signaling of a component carrier, wherein the second type of SRS configuration is based on a second set of available configurations for SRS received over a second higher layer protocol signaling, and wherein the first higher layer protocol signaling is different from the second higher layer protocol signaling, and transmits one or more SRS-for-positioning purposes based on the first or second type of SRS configuration.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE or base station performs, during a positioning session, a measurement of a first positioning reference signal (PRS) within a first bandwidth part (BWP), performs, during the positioning session, a measurement of a second PRS within a second BWP, transmits, to a location server, a measurement report including the measurement of the first PRS and the measurement of the second PRS, and transmits, to the location server, an indication of the first BWP, the second BWP, or both.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station performs one or more angle-based measurements in a first coordinate system, determines whether to report, to a positioning entity, the one or more angle-based measurements in a local coordinate system (LCS) or a global coordinate system (GCS), and reports the one or more angle-based measurements to the positioning entity in the LCS or the GCS based on the determination. In an aspect, a positioning entity receives, from a base station, one or more angle-based measurements in an LCS of the base station or a GCS, determines whether the one or more angle-based measurements are in the LCS or the GCS, and processes the one or more angle-based measurements based on the determination.

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: In an embodiment, a UE selects between RS collision protocols to selectively monitor, on downlink resource(s) scheduled with overlapping transmissions of first and second RS types, either the first RS type or neither RS type. In another embodiment, a base station determines that a downlink resource(s) are scheduled with overlapping transmissions of first and second RS types, punctures the second RS type, and selectively transmits the first RS type on the overlapped downlink resource(s). In another embodiment, a base station establishes non-overlapping NPRS and eNPRS transmission schedules.

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.

Abstract: Many mobile devices and mobile networks utilize orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, the Doppler Effect and other noise or obstructions can cause OFDM signals to become entangled, particularly when the mobile device is moving, making the calculated position information inaccurate. Described herein are systems and methods for disentangling the OFDM signals by calculating a symbol length for the signals that is longer than the minimum symbol length, which is used in traditional OFDM. Selecting a longer symbol length reduces the Doppler Effect and other noise on the signals, making positioning calculations more accurate.
