Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engaged in a positioning session with a plurality of transmission-reception points (TRPs) receives a downlink positioning reference signal (DL-PRS) configuration specifying one or more DL-PRS resource sets of a DL-PRS instance, wherein all DL-PRS resources of the one or more DL-PRS resource sets of the DL-PRS instance are scheduled within a time window, and receives an uplink PRS (UL-PRS) configuration specifying one or more UL-PRS resource sets, wherein all of the one or more UL-PRS resources are scheduled within the time window. The UE may perform, during the time window, measurements of DL-PRS transmissions on one or more DL-PRS resources of the one or more DL-PRS resource sets, and transmit, during the time window, at least one UL-PRS on the one or more UL-PRS resources.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: Techniques are provided for passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first station at a first time, receiving a second positioning reference signal from a second station at a second time, receiving a turnaround time value associated with the first positioning reference signal and the second positioning reference signal, and a distance value based on a location of the first station and a location of the second station, and determining a time difference of arrival based at least in part on the turnaround time value, the distance value, the first time, and the second time.

Abstract: This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

Abstract: Methods, systems, and devices for wireless communications are described in which a two-stage interleaving pattern may be provided for communication of coded information via a channel. The channel may have a channel bandwidth within a bandwidth part (BWP) of a total frequency bandwidth, and the two-stage interleaving pattern may provide a first interleaving pattern of resource blocks within an allocated set of user equipment (UE) resources and a second interleaving pattern of resource blocks within the BWP. The two-stage interleaving pattern may be based on the first interleaving pattern being initially applied to resource blocks within the allocated set of UE resources, and the second interleaving pattern being subsequently applied to resource blocks within the BWP. Signaling to indicate a type of interleaving to be applied to a communication may be provided in semi-static signaling, dynamic signaling, or combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with quasi co-located (QCL) associations between a physical uplink control channel and a sounding reference signal (SRS) transmission for at least one time and frequency domain channel parameter. The UE may transmit, in accordance with the QCL association, a control channel transmission via the physical uplink control channel using an antenna port that is quasi co-located with at least one antenna port for transmitting the SRS transmission and transmit, in accordance with the QCL association, the SRS transmission via the at least one antenna port. In another example, the base station may configure the UE with an antenna port association between an SRS transmission and a physical uplink control channel. The UE may transmit the SRS transmission and a control channel transmission in accordance with the antenna port association.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an assisting user equipment (UE) receives a request to perform a positioning procedure from a target UE over a sidelink between the assisting UE and the target UE, wherein the assisting UE and the target UE are both out of network coverage, determines, based at least on the request, a set of time and/or frequency resources on which to transmit one or more positioning reference signals for the positioning procedure, and transmits the one or more positioning reference signals to the target UE via the set of time and/or frequency resources.

Abstract: A method of coordinating positioning signaling includes: identifying a first user equipment (UE) served by a base station and a second UE served by the base station, the base station being configured to send a base station positioning signal wirelessly at a plurality of base-station-transmission times; allocating first times to the first UE, for sending first UE positioning signals, and second times to the second UE, for sending second UE positioning signals, at least one of the first times being different from at least one of the second times; sending a first communication to cause the first UE to send at least a respective one of the first UE positioning signals at each of the first times; and sending a second communication to cause the second UE to send at least a respective one of the second UE positioning signals at each of the second times.

Abstract: Disclosed are techniques for handling an overlap between a higher priority channel and a lower priority channel. In an aspect, a transmitter node detects an overlap between an allocation of a first set of resources of a wireless communication link for transmission of the lower priority channel and an allocation of a second set of resources of the wireless communication link for transmission of the higher priority channel, removes a subset of resources from the first set of resources to generate a removed subset of resources of the first set of resources and a remaining subset of resources of the first set of resources, and transmits, to a receiver node, the lower priority channel on the remaining subset of resources, wherein the higher priority channel is transmitted on the removed subset of resources, wherein the higher priority channel or the lower priority channel is a positioning reference signal.
