Abstract: A wireless communication device may include one or more memories, individually or in combination, having instructions and one or more processors, individually or in combination, configured to execute the instructions. In some examples, the wireless communication device may be configured to transmit a first signal. In some examples, the wireless communication device may be configured to transmit, after the first signal, a first plurality of signals including a second signal, wherein each of the plurality of signals is transmitted via one of a plurality of codebook directional beams. In some examples, the wireless communication device may be configured to receive, from a first energy harvesting (EH) device of a plurality of EH devices, a first backscatter signal in response the second signal, wherein the first backscatter signal indicates that the second signal satisfies a threshold condition.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity includes determines common assistance data for a joint position estimation group, and sends to first and second UEs. The position estimation entity further sends indications of which PRS resources associated with the common assistance data is active for the first and second UEs. The position estimation entity receives measurement information from the first and/or second UEs, and derives position estimations of the first and second UEs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a location server may receive measurement reports from one or more receiving radio frequency identification (RFID) stations, the measurement reports being based on a backscattered signal from an RFID device observed at the one or more receiving RFID stations, and the backscattered signal being based on a positioning reference signal transmitted by a user equipment (UE). The location server may determine an estimated position of the RFID device based on the measurement reports.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.

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 minor symmetry in positioning solutions.
