Abstract: Disclosed are techniques for muting positioning reference signals. In aspects, a location server sends, to a user equipment (UE), a plurality of positioning reference signal configurations and one or more positioning reference signal muting configurations associated with a transmission-reception point (TRP) identifier (ID) and/or a positioning reference signal ID. A first TRP sends, to the UE, a command triggering at least one positioning reference signal muting configuration, wherein the triggered positioning reference signal muting configuration indicates that: the one or more positioning reference signals of the one or more positioning reference signal occasions of at least one positioning reference signal configuration are not being transmitted, or the one or more positioning reference signals of the one or more positioning reference signal occasions of all of the plurality of positioning reference signal configurations are not being transmitted, and mutes positioning reference signals according to the triggered positioning reference signal muting configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A device (e.g., a base station or a user equipment (UE)) may identify a sequence length corresponding to a number of resource blocks, and select a modulation scheme based on the sequence length. The device may select, from a set of sequences associated with the modulation scheme, a sequence having the sequence length. In some examples, the set of sequences may include at least one of a set of time domain phase shift keying computer-generated sequences or a set of frequency domain phase shift keying computer-generated sequences. The device may generate a reference signal for a data transmission based on the sequence and transmit the reference signal within the number of resource blocks.

Abstract: A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, an indication of a set of resources for transmitting a set of phase-coherent sounding reference signals (SRSs). The UE may receive, from the base station, a control message indicating a cancellation of an allocation of a first portion of the set of resources. The UE may determine a phase coherency configuration associated with a second portion of the set of resources based on receiving the control message indicating the cancellation. The UE may then be configured to transmit one or more SRSs within the second portion of the set of resources in accordance with the determined phase coherency configuration.

Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.

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: In at least one embodiment, a user equipment (e.g., a mobile device) may receive a location request message from a server (e.g., a Location Management Function), wherein the location request message identifies a plurality of Quality of Service parameters for the LTE Positioning Protocol (LPP) positioning session. In at least one embodiment, the user equipment may receive a selection of one or more Quality of Service parameters for the LPP positioning session. In at least one embodiment, the user equipment may configure the user equipment according to the one or more selected Quality of Service parameters. In at least one embodiment, the user equipment may generate a location response message according to the selected QoS parameters. The user equipment may send the location response message to the server. A UE can select the QoS parameters during communication with a server and/or with a second UE via sidelink communications.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE obtains measurement data associated with at least one PRS. The UE transmits, to a BS in a first L1 or L2 PSI report opportunity, a first PSI report indicative of a first set of measurement values associated with the at least one PRS based on the measurement data. The UE further transmits, to the BS in a second L1 or L2 PSI report opportunity that is subsequent to the first L1 or L2 PSI report opportunity, a second PSI report that is indicative of a second set of measurement values associated with the at least one PRS based on the measurement data, the second set of measurement values being refined from the first set of measurement values.
