Abstract: In an aspect, a first BS measures a SRS-P associated with a RTT measurement procedure between a UE and a second base station, and reports measurement information based on the measurement of the SRS-P. In another aspect, a device (e.g., UE, BS, LMF, etc.) obtains the measurement information along with measurement information based on measurements at the UE and the second base station, and determines a positioning estimate of the UE based on the first, second and third measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may receive different configurations for determining a first transmit power for data transmissions and a second transmit power for energy harvesting transmissions. The different configurations may include different parameters for determining (e.g., calculating) the first transmit power and the second transmit power. In some aspects, the transmitting UE may also receive an indication of the second transmit power from a receiving UE such that the second transmit power may be determined in accordance with the capabilities of the receiving UE (e.g., based on an energy harvesting circuit at the UE). The indication of the second transmit power may be an indication of one or more parameters used to determine (e.g., calculate) the second transmit power.

Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) configured to operate in discontinuous reception (DRX) mode receives a configuration of a plurality of DRX groups, receives one or more positioning reference signal (PRS) configurations for the plurality of DRX groups, each of the one or more PRS configurations indicating one or more PRS resources for each of the plurality of DRX groups, receives one or more wakeup signals (WUS) for the plurality of DRX groups, the one or more WUS indicating whether or not the UE is expected to wake up for a next DRX cycle of each of the plurality of DRX groups, and measures/transmits the one or more PRS resources for each of the plurality of DRX groups during the next DRX cycle of each of the plurality of DRX groups based, at least in part, on the one or more WUS.

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: A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.

Abstract: Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method for wireless communication by a user equipment (UE) includes receiving a positioning reference signal in a time slot, wherein the positioning reference signal spans a first frequency bandwidth, transmitting a signal in a second frequency bandwidth during the time slot, wherein the second frequency bandwidth includes frequencies within the first frequency bandwidth, and processing the positioning reference signal received in the first frequency bandwidth excluding the frequencies in the second frequency bandwidth.

Abstract: Methods, systems, and devices for wireless communications are described. To support sidelink coherency management, a user equipment (UE) may transmit a sidelink reference signal to a second UE on an active bandwidth part (BWP) or on a first component carrier (CC), the sidelink reference signal associated with a subsequent transmission of a sidelink message on the active BWP or on the first CC. The UE or the second UE may determine whether the UE switches to a second active BWP or transmits a second sidelink message on a second CC prior to transmitting the sidelink message. Additionally, or alternatively, the UE or the second UE may determine whether the UE switches between full-duplex mode and/or a half-duplex mode prior to or concurrent with transmitting the sidelink message. Based on the determination, the UE may transmit the sidelink message according to a first set of coherency transmission characteristics.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a first set of sidelink feedback messages to transmit and a second set of sidelink feedback messages to receive, the first set of sidelink feedback messages scheduled to be transmitted concurrently with the second set of sidelink feedback messages. The UE may select a first subset of sidelink feedback messages from the first set of sidelink feedback messages to transmit and a second subset of sidelink feedback messages from the second set of sidelink feedback messages to receive based at least in part on a priority level associated with each sidelink feedback message and a first set of frequency domain resources for the first subset of sidelink feedback messages and a second set of frequency domain resources for the second subset of sidelink feedback messages.
