Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode a sequence associated with an acknowledgement status using a symmetric key. The symmetric key may be determined using channel reciprocity at a physical layer or may be determined using a higher layer of the UE. Accordingly, the UE may transmit the sequence associated with the acknowledgement status. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a configuration of one or more resource pools for positioning (RP-Ps) to use for transmission, reception, or both of sidelink positioning reference signals (SL-PRS), measures at least a first channel busy ratio (CBR) associated with a first RP-P of the one or more RP-Ps, and transmits, to at least a second UE, one or more SL-PRS resources in the first RP-P, wherein transmission parameters of the one or more SL-PRS resources are based on the first CBR associated with the first RP-P.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives positioning reference signal (PRS) resources of a PRS instance, receives at least one symbol of a high priority downlink channel scheduled during a PRS processing window for the PRS instance, wherein the high priority downlink channel is determined to have high priority based on the high priority downlink channel being associated with a high priority uplink channel, and refrains from processing the PRS resources of the PRS instance during the PRS processing window based on one or more conditions related to prioritizing PRS processing, wherein the one or more conditions indicate that the UE does not expect to process the PRS resources of the PRS instance during the PRS processing window based on the at least one symbol of the high priority downlink channel being scheduled during the PRS processing window.

Abstract: Aspects of the present disclosure are directed to techniques for enhancing security of wireless communications; specifically, physical (PHY) level communications. In some examples, the disclosure is directed to a user equipment (UE) configured to receive, from a base station, a configuration including a key extraction mode. In certain aspects, the UE may transmit a sounding reference signal (SRS) to the base station. In certain aspects, the UE may receive a signal from the base station in response to the SRS, wherein, in response to the key extraction mode, the signal is precoded based on a key. In certain aspects, the UE may extract the key from the signal.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a PRS sequence is determined based in part on a sidelink zone where a transmitting UE is located. A receiving UE may perform a blind search based on PRS sequence(s) associated with its own sidelink zone and/or neighboring sidelink zones. In other aspects, measurement reports may be conveyed to a position estimation entity with positioning measurements being associated with respective PRS sequences, which can then be correlated to the respective transmitting UEs at the position estimation entity so as to facilitate position estimation of a target UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may precode sounding reference signals using an interference covariance matrix to report channel quality information to a base station. For example, a UE may receive an indication of a future time from a base station. The future time may correspond to a future time for which the UE may predict an interference covariance matrix. In some cases, based on receiving the indication, the UE may monitor for interference in one or more interference measurement resources. In some examples, the UE may then determine the predicted interference covariance matrix and may transmit a sounding reference signal to the base station. The sounding reference signal may be precoded based on the predicted interference covariance matrix. In some cases, the UE may receive a downlink signal from the base station at the future time or at a second time.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive a first indication to perform a first positioning measurement having a first measurement method type and targeting a first positioning frequency layer (PFL). The UE may receive, prior to completion of measurements associated with the first positioning measurement, a second indication to perform a second positioning measurement having a second measurement method type and targeting a second PFL. The UE may determine an order in which to perform the measurements associated with the first indication and measurements associated with the second indication. The UE may perform the measurements associated with the first indication and the measurements associated with the second indication according to the order.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode receives, from a location server, an anchor selection update message indicating that the UE has been selected as an anchor UE for a joint positioning session with one or more second UEs, wherein the UE is selected as the anchor UE based at least in part on the UE having DRX active time occasions closer to a plurality of measurement occasions for the joint positioning session than DRX active time occasions of the one or more second UEs, performs positioning measurements for the joint positioning session during one or more measurement occasions that overlap with the DRX active time occasions of the UE, and transmits, to the one or more second UEs, the positioning measurements, a location of the UE determined based on the positioning measurements, or both.

Abstract: Techniques are provided for utilizing positioning reference signals (PRS) to determine a location of a wireless node. An example method for reporting positioning reference signals measurement values with a wireless node includes providing capabilities information including an indication of a number of positioning frequency layers to be included in a single measurement report, and an indication of a number of positioning frequency layers that can be measured simultaneously, receiving positioning assistance data comprising positioning reference signal configuration information, measuring positioning reference signals in the number of positioning frequency layers to be included in the single measurement report based at least in part on the positioning assistance data, and transmitting the single measurement report.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, UE determines an expected association between at least one UE Tx TEG and SRS for a position estimation procedure, the at least one UE Tx TEG indicating that transmit timing errors of the SRS are within a margin. UE transmits an indication of the expected association to a position estimation entity (e.g., another UE, gNB, LMF, etc.). UE transmits the SRS (e.g., either in accordance or discordance with the expected association). The position estimation entity processes measurement information associated with the position estimation procedure based in part upon the indication of the expected association.
