Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine downlink (DL) channel state information; and transmit a first sounding reference signal (SRS) and a second SRS, wherein the second SRS is precoded based at least in part on the DL channel state information. Numerous other aspects are provided.

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: Techniques are discussed herein for providing on-demand positioning reference signals (PRS) to user equipment (UE). An example method for determining a location of a user equipment according to the disclosure includes receiving a first assistance data associated with a first positioning reference signal configuration, transmitting a request to modify one or more parameters of the first positioning reference signal configuration, receiving a second assistance data associated with a second positioning reference signal configuration, wherein the second positioning reference signal configuration is based at least in part on the request to modify the one or more parameters of the first positioning reference signal configuration, obtaining measurements from one or more positioning reference signals based at least in part on the second assistance data, and determining the location based at least on part on measurements obtained from the one or more positioning reference signals.

Abstract: Techniques are provided for signaling timing error group (TEG) updates for positioning. An example for providing reference signal measurement values with a mobile device incudes measuring one or more reference signals, determining a timing error change associated with one or more reference signal measurement values, and transmitting the one or more reference signal measurement values and an indication of the timing error change.

Abstract: The positioning capabilities of a User Equipment (UE) are stored in a core network to reduce positioning latency when the UE indicates that its positioning capabilities are stable and/or are long term valid. The UE may provide its positioning capabilities to a location server during a location session along with an indication of whether the positioning capabilities are stable. The location server may enable storage of the positioning capabilities for the UE in the core network, e.g., in the location server or another entity in the core network such as Access and Mobility Management Function (AMF), if there is an indication that the positioning capabilities are stable. The AMF may include a UE identifier in location requests with which the location server may retrieve the UE positioning capabilities if stored at the location server or may include the UE positioning capabilities if stored at the AMF.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.

Abstract: Some aspects of the present disclosure provide channel state information (CSI) processing criteria. A method that may be performed by a user equipment (UE) generally includes receiving, from a base station via a first bandwidth part (BWP), control signaling that triggers reporting at least one of a first channel state information (CSI) report associated with the first BWP or a second CSI report associated with a second BWP that is non-active, determining, based on an indication of an active downlink (DL) BWP change, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report, and taking one or more actions based at least in part on the at least one occupation time.
