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.

In some aspects, a method of wireless communication performed by a user equipment (UE) includes determining a positioning reference signal (PRS) to random access channel (RACH) occasion (RO) mapping that defines specific ROs during which the UE should at least transmit a RACH sequence based on specific PRS measurements. The method also includes performing at least one PRS measurement.

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: A method of wireless communication by a user equipment (UE) includes receiving an uplink grant from a network device. The method also includes determining, by a lower analog media access control (MAC-A) layer of an analog data communications stack, a quantity of analog neural network gradients to transmit in a data packet using resources allocated by the uplink grant. The determining is based on an analog physical (PHY-A) layer encoding scheme and the resources allocated by the uplink grant. The method further includes segmenting the analog neural network gradients into the data packet. The method still further includes transferring the data packet to the PHY-A layer for transmission to the network device across a wireless network.

Abstract: A user equipment (UE) receives scheduling information for Sounding Reference Signal (SRS) for positioning that includes multiple reserved occasions to transmit the SRS. The multiple reserved occasions may be used on all or on only a subset of configured SRS resources. The UE transmits the positioning SRS on a reserved occasion that is first available for transmission, e.g., without collision or other restrictions of transmission of the SRS. The UE does not transmit the positioning SRS on any earlier reserved occasions that is not available or any subsequent reserved occasions. The base station may attempt to decode the SRS on each reserved occasion until the positioning SRS is transmitted. The base station may reassign unused reserved occasions to other UEs or to other channels. The base station may report positioning measurements with associated time stamps for the reserved occasion on which the positioning SRS was received.

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.
