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: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates an association between a sounding reference signal (SRS) resource set and a downlink reference signal resource to be used to determine a transmission property of one or more SRSs in the SRS resource set, wherein the downlink reference signal resource is associated with a first set of ports to be used for performing measurement of the downlink reference signal resource. The UE may determine the transmission property of the one or more SRSs in the SRS resource set using fewer ports than a number of ports included in the first set of ports, based at least in part on a determination that the UE is operating in a power saving mode. The UE may transmit the one or more SRSs using the transmission property. Other aspects are provided.

Abstract: Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a receiver device receives, from a transmission point, a reference RF signal on a wireless channel receives, from a positioning entity, an indication that the reference RF signal serves as a source for a quasi-collocation (QCL) type(s) for positioning reference RF signals received by the receiver device from the transmission point on the wireless channel, measures an average delay, a delay spread, or both the average delay and the delay spread of the reference RF signal based on the QCL type(s), receives, from the transmission point, a positioning reference RF signal on the wireless channel, and identifies a time of arrival (ToA) of the positioning reference RF signal based on the measured average delay, the delay spread, or both the average delay and the delay spread of the reference RF signal.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a band-pass filter of a radio frequency front end (RFFE) of a user equipment (UE) receives an analog radio frequency (RF) signal having a first bandwidth associated with a first sampling rate, the analog RF signal comprising a positioning reference signal (PRS). An analog-to-digital converter (ADC) of the UE samples the analog RF signal at a second sampling rate to generate a digital RF signal representing the analog RF signal, wherein the ADC operates at a second bandwidth lower than the first bandwidth, and wherein the second sampling rate is lower than the first sampling rate by an inverse of a folding factor for the first bandwidth. The digital RF signal is then output to a baseband processor of the UE.

Abstract: Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: Disclosed are techniques for scheduling uplink (UL) and downlink (DL) physical layer resources for a serving node and a user equipment (UE) for round trip time (RTT) and observed time difference of arrival (OTDOA) based positioning. In an aspect, a serving node and/or a network entity configure the UL and DL physical layer resources, and inform the UE. A network node transmits RTT measurement (RTTM) signal to the UE and receives RTT response (RTTR) signals from the UE. The network node measures the times the RTTM signals are transmitted and the times the RTTR signals are received. The UE provides to serving node processing times indicating a duration between the UE receiving the RTTM signals and the UE transmitting the RTTR signals. The RTTs are calculated from the times measured by the network node and the processing times provided by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a user equipment (UE) receiving a set of downlink reference signals associated with a downlink channel. In some cases, the set of downlink reference signals may include a channel state information reference signals (CSI-RS). The UE may calculate a transmission rank and a channel quality based on the received set of downlink reference signals. In some cases, the indication of the transmission rank may include a rank indication (RI), and the indication of the channel quality includes a channel quality indicator (CQI). The UE may then transmit the indications of the transmission rank and the channel quality using an uplink control channel, and may transmit an indication of a remaining channel state feedback using a precoded uplink reference signal.
