Abstract: Methods and apparatus for predicting wireless measurements based on virtual access points is described. In some embodiments, a location of a user equipment (UE) may be obtained, and given the location of the UE, an output may be generated using a machine learning model, the output including one or more predicted wireless measurements. The output may be indicative of a wireless channel in a multipath environment. In some variants, the machine learning model may have been trained by obtaining a training dataset comprising multipath components data and ground truth locations of a wireless device, and performing an optimization with respect to the multipath components data and the ground truth locations. In some implementations, a training output comprising a predicted multipath component may be produced during the training, and the optimization may include an iterative minimization of an error between at least the predicted multipath component and a labeled multipath component.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network entity, such as a location server, may determine first information characterizing a channel associated with a wireless device within a region of interest. The network entity may determine a location of the wireless device within the region of interest based on the first information characterizing the at least one channel associated with the wireless device and a plurality of radio frequency fingerprints (RFFPs), wherein each RFFP of the plurality of RFFPs identifies a geographic location within a region of interest and a channel condition at that geographic location within the region of interest, and wherein each geographic location within the region of interest is represented by a plurality of RFFPs having different channel conditions due to different states of at least one reconfigurable intelligent surface (RIS) within the region of interest.

Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve mirror symmetry in positioning solutions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.

Abstract: Techniques are provided for passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first station at a first time, receiving a second positioning reference signal from a second station at a second time, receiving a turnaround time value associated with the first positioning reference signal and the second positioning reference signal, and a distance value based on a location of the first station and a location of the second station, and determining a time difference of arrival based at least in part on the turnaround time value, the distance value, the first time, and the second time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message, from a network entity, indicating assistance information including a decoding order, decoder iteration instructions, or both, for a first set of repetitions of a data transmission. The UE may monitor for and receive the first set of repetitions from the network entity and decode the first set of repetitions based on the assistance information from the network entity. Based on decoding the first set of repetitions, the UE may transmit a feedback message to the network entity indicating whether the UE successfully decoded the first set of repetitions.

Abstract: An irregular slot may include a scenario in which a user equipment (UE) transmits a sensing signal, which may be an uplink transmission, in a downlink slot or a flexible slot. In some other examples, an irregular slot may include a scenario in which a transmit receive point (TRP) transmits a sensing signal, which may be a downlink transmission, in an uplink slot or a flexible slot. As a result, the sensing signal transmission can degrade throughput and/or quality of service of other communication devices' transmissions. Accordingly, a wireless communication device, such as a UE or a TRP, that is to transmit a sensing signal in an irregular slot may be configured with a power constraint parameter or a beam parameter. In some examples, aspects of the present disclosure may reduce an impact of interference or noise on other wireless communication devices' transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques enable user equipment (UEs) to perform feedback reporting. A first UE may communicate an indication that it is in a UE group associated with uplink feedback resource sharing among UEs in the UE group. The first UE may then receive one or more messages indicating sets of uplink feedback resources associated with the first UE and one or more other UEs in the UE group, the uplink feedback resources being configured for uplink feedback resources sharing. The UEs within the UE group may support shared feedback resources so that a UE may access and utilize any quantity of feedback resources associated with any UE that belongs to the same cooperative group. The first UE may select a resource from the sets of uplink feedback resources and may communicate uplink feedback based on the selection.

Abstract: A user equipment (UE) is configured for supporting positioning using sounding reference signal (SRS) periodic burst transmissions that includes a plurality of sets of SRS transmissions, where each set of SRS transmissions includes a repetition of SRS resources. The configuration for the SRS periodic burst transmissions includes a start time for the SRS periodic burst transmissions, a repetition configuration for the SRS resources within each set, and a repetition configuration for the plurality of sets of SRS transmissions. The configuration may be received in a Radio Resource Control (RRC) configuration message or a Medium Access Control-Control Element (MAC-CE) message that activates the SRS periodic burst transmissions, and the SRS periodic burst transmissions may be deactivated with a RRC reconfiguration message or another MAC-CE message.
