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.

Abstract: In an aspect, a UE receives first positioning assistance data (AD). The UE transmits an indication to a network component (e.g., BS, core network component, LMF, etc.) that the UE has received the first positioning AD. The network component determines second positioning AD that is based at least in part upon the first positioning AD. The network component transmits the second positioning AD to the UE.

Abstract: Methods, systems, computer-readable media, and apparatuses for determining a UE position within a coverage sub-area of a cell based on cell identity data are presented. In some embodiments, the UE detects one more cell identities, including a cell identity of a serving cell and possibly a cell identity of a neighbor cell of the serving cell. The one or more cell identities are included in cell identity data. The cell identity data is used in a look up of a data structure that associates coverage sub-areas of a coverage area of the serving cell with most likely positions within the coverage sub-areas and with cell identities. The result of the look up indicates that the UE is positioned at a most likely position within a coverage sub-area of the serving cell.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits, to a network entity, one or more capability messages indicating one or more capabilities of the UE to process positioning reference signals (PRS), the one or more capabilities indicating at least a duration of PRS that the UE can process within a measurement window without a measurement gap, and performs one or more positioning measurements of one or more PRS resources during the measurement window up to the duration of PRS.

Abstract: In an aspect, a UE receives, from a network entity, a configuration of PRS or SRS-P resources for a positioning session, receives a configuration of at least one BWP from a serving BS, identifies a time-domain period for the positioning session where a set of parameters associated with the at least one BWP is to remain constant to achieve a first positioning accuracy requirement. The UE either performs positioning measurements on one or more of the PRS resources during the positioning session or transmits on one or more of the SRS-P resources during the positioning session. The UE determines an active BWP transition during the time-domain period from a first BWP to a second BWP that is associated with one or more changes to the set of parameters.

Abstract: Embodiments herein provide for a Low-Frequency (LF) broadcast system that improves on the LORAN-C system to help optimize the use of available spectrum while modernizing the signal structure of broadcast signals. In particular, embodiments can utilize an Orthogonal Frequency Division Multiplexing (OFDM) signal structure to broadcast timing and data signals in successive symbols of an OFDM resource block. Signals can include, for example, comb-1, comb-2, or comb-3 signal structures. Other signal aspects such as muting schemes, modulation, frequency offsets, and the like may vary, depending on desired functionality.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a user equipment (UE) includes receiving, from a network entity, a plurality of positioning reference signal (PRS) configurations for one or more serving or neighboring transmission-reception points (TRPs), receiving, from the network entity, a set of parameters that indicate time and frequency locations of one or more synchronization signal blocks (SSBs) of the one or more serving or neighboring TRPs, and determining which PRS of the plurality of PRS configurations have been punctured by the one or more SSBs based on the set of parameters.

Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

Abstract: Disclosed are techniques for utilizing synchronization signal blocks for positioning operations. In an aspect, a transmission point configures a set of synchronization signal blocks to be used as positioning measurement signals, each of the plurality of synchronization signal blocks comprising a primary synchronization signal, a secondary synchronization signal, and one or more physical broadcast channel signals, and transmits the set of synchronization signal blocks on a wireless downlink channel to enable a user device to perform a positioning measurement of at least one of the set of synchronization signal blocks. In an aspect, the user device receives, from the transmission point, the plurality of synchronization signal blocks on the wireless downlink channel, receives, from the transmission point, an indication of the set of synchronization signal blocks to be used as positioning measurement signals, and performs a positioning measurement of at least one of the set of synchronization signal blocks.
