    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving cell, an uplink positioning reference signal (UL-PRS) resource configuration, the UL-PRS resource configuration comprising a plurality of N resource elements (REs) staggered in frequency across a plurality of M consecutive symbols of a resource block (RB) such that the plurality of N REs spans a plurality of N consecutive subcarriers of the RB, receives, from the serving cell, an indication of a PRS symbol cancelation group to be used for uplink cancelation, the PRS symbol cancelation group identifying a set of the plurality of M consecutive symbols that is expected to be canceled for uplink transmission, and cancels transmission of UL-PRS on one or more of the set of L symbols identified by the PRS symbol cancelation group.

    Abstract: Techniques are provided for determining a path loss for semi-persistent SRS-for-positioning if the path loss resource set is not updatable through a MAC CE. An example method according to the disclosure includes receiving, from a serving base station, a medium access control control element, determining a spatial relation reference of a first sounding reference signal resource, setting a path loss reference for a sounding reference signal for positioning resource set to the spatial relation reference if the spatial relation reference is not an uplink reference signal, setting the path loss reference equal to a reference system resource from a synchronization signal block the user equipment utilizes to obtain a master information block if the spatial relation reference is an uplink reference signal, and transmitting the resources of the sounding reference signal for positioning resource set based at least in part on the path loss reference.

    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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an indication of a null resource element pattern. The null resource element pattern may be indicated in the DCI using: a value of an antenna port field that also indicates one or more demodulation reference signal (DMRS) ports for the UE and a number of DMRS code-division multiplexing groups without data, or one or more zero power downlink reference signals. The UE may perform one or more demodulation interference measurements based at least in part on the null resource element pattern. The UE may demodulate a downlink communication based at least in part on performing the one or more demodulation interference measurements. Numerous other aspects are provided.
