    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: 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.

    Abstract: Certain aspects of the present disclosure provide techniques for avoiding transmission configuration indication (TCI) reselection (e.g., due to some bandwidth part (BWP) switching scenarios). An exemplary method generally includes configuring a UE with TCI state information for communication via multiple BWPs, wherein the TCI state information indicates quasi co-location (QCL) assumptions of at least first and second types and determining whether to reconfigure the TCI state of the UE to reflect a BWP switch, based on one or more rules that define BWP switching for reference signals (RSs) of at least one of the QCL assumption types without TCI state reconfiguration. Other aspects and embodiments are also claimed and described.

    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.
