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.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple instances of aperiodic tracking reference signals (TRSs) that use a same set of large-scale channel properties. If two or more aperiodic TRS transmissions are triggered by downlink control information from a base station with a same transmission configuration indicator (TCI) state, a UE that receives the two or more aperiodic TRS transmissions may measure the multiple instances of the aperiodic TRS transmissions assuming that the same large scale parameters or properties can be inferred from each of the aperiodic TRS transmissions. The UE may then update one or more time tracking parameters, frequency tracking parameters, or combinations thereof, based on the same large scale transmission parameters being used for the multiple instances of the aperiodic TRS transmissions.

Abstract: A method of determining a location of a user equipment includes: obtaining, at the user equipment, a position-determination model associated with a coarse location of the user equipment; determining one or more first positioning measurements at the user equipment; and determining, at the user equipment, the location of the user equipment based on the one or more first positioning measurements and the position-determination model.

Abstract: Certain aspects of the present disclosure provide techniques for providing channel state information associated with sidelink air interfaces. A method that may be performed by a first wireless node (e.g., a user equipment) includes receiving, from a base station, a reference signal (RS) configuration indicating one or more sidelink resource sets and transmitting, to one or more second wireless nodes, one or more sidelink reference signals based at least in part on the RS configuration. The method also includes receiving one or more feedback reports from the one or more second wireless nodes, wherein each of the feedback reports includes an ordered sequence of at least one parameter associated with a sidelink channel quality of the sidelink reference signals. The method further includes forwarding the one or more feedback reports to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. One or more reference signals may be transmitted by a user equipment (UE) that may be used by a base station for channel estimation and determination of one or more parameters to be used for subsequent uplink transmission of the UE. The base station may transmit an indication of uplink transmission parameters in an uplink grant that is transmitted to the UE. The UE may modify one or more subsequent reference signal transmissions based on the uplink grant received from the base station and a timing of the uplink grant relative to the one or more subsequent reference signal transmissions. The base station may determine a timing for the uplink grant based on a timing associated with the reference signal transmissions from the UE.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method may be performed by a wireless device such as a user equipment (UE) and generally includes: receiving at least one downlink (DL) signal from one or more base stations or transmitting at least one uplink (UL) positioning reference signal (PRS), the received at least one DL signal comprising: at least one DL PRS, at least one synchronization signal block (SSB), at least one system information block (SIB), at least one other reference signal comprising a channel state information reference signal (CSI-RS), or a combination thereof, wherein at least one measurement is performed based, at least in part, on the received at least one DL signal or the transmitted at least one UL PRS; and performing at least one adjustment for random access based, at least in part, on the at least one measurement.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate a signal-to-noise ratio for each antenna port associated with a reception of one or more tracking reference signals. The UE may receive one or more of multiple single-port tracking reference signals, a single multi-port tracking reference signal, or a tracking reference signal associated with multiple power ratios. The UE may be able to estimate a channel upon receiving a demodulation reference signal. The channel estimation may be based on the reception of one or more of multiple single-port tracking reference signals, the single multi-port tracking reference signal, or the tracking reference signal associated with multiple power ratios. The UE may communicate with the base station based on estimating the channel.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.
