Abstract: Disclosed are techniques for communication. In an aspect, a wireless node receives a configuration associated with one or more reference signal for positioning (RS-P) resources from a position estimation entity. The wireless node performs measurement(s) of a set of RS-P resources, and derives measurement information associated with a first virtual instance of the one or more RS-P resources based on the measurement(s). The wireless node transmits a measurement report comprising the measurement information to the position estimation entity.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a request location information message from the network entity, the request location information message including one or more start measurement time parameters indicating a start time of a measurement period during which the UE is expected to perform one or more positioning measurements, and performs the one or more positioning measurements of one or more positioning reference signal (PRS) resources on a first positioning frequency layer during the measurement period, wherein a start of the measurement period is based on the one or more PRS resources, a reception time, and the one or more start measurement time parameters.

Abstract: Disclosed are systems, methods, and non-transitory media for providing signaling consideration for wireless positioning with disjoint bandwidth segments. For instance, one or more indications of a preferred bandwidth configuration can be transmitted by a user equipment. Based on the one or more indications, the user equipment can receive a positioning configuration that indicates disjoint bandwidth segments containing a positioning reference signal based on the preferred bandwidth configuration. In response, the user equipment can then determine one or more positioning measurements based on the positioning reference signal in the disjoint bandwidth segments.

Abstract: A method at a UE for responding to a change in physical state of the UE includes: determining that a physical relationship between a first antenna element of the UE and another component of the UE has changed from a first state; and providing at least one notification in response to determining that the physical relationship between the first antenna element and the other component of the has changed from the first state.

Abstract: Methods, systems, and devices for wireless communication are described. Aspects of the disclosure describe narrow beam-based channel access that enables a device to communicate in a shared radio frequency spectrum band without performing channel access procedures. Specifically, aspects of the disclosure describe techniques for defining one or more directional beams as a narrow beam, where the relative narrowness of the beam may be determined in the context of interference (e.g., as opposed to being defined from a geometric perspective). For example, a particular beam may be determined to be a narrow beam, and therefore associated with communications in shared radio frequency spectrum bands without channel access procedures, based on one or more metrics and a number of spatial streams associated with the beam. A device may use such narrow beams for communications without channel access procedures in shared radio frequency spectrum bands.

Abstract: Disclosed are techniques for wireless sensing and/or positioning. In an aspect, a base station (BS) may define a resource set comprising a plurality of phase-coherent positioning resources, the phase-coherent positioning resources comprising phase-coherent positioning reference signal (PRS) resources, phase-coherent sounding reference signal (SRS) resources, or a combination thereof. The BS may configure a user equipment (UE) with the resource set. The BS may use the plurality of phase-coherent positioning resources, including transmitting phase-coherent PRS signals using the phase-coherent PRS resources, receiving phase-coherent SRS signals using the phase-coherent SRS resources, or a combination thereof.

Abstract: In an aspect, a wireless node (e.g., UE, gNB, etc.) receives a reference signal for positioning (RS-P) over a respective bandwidth on one or more paths including an earliest path, and measures a reference signal received power (RSRP) associated with the earliest path of the RS-P based on a sum of energy on the respective bandwidth within at least one number of samples from a peak of the earliest path.

Abstract: In an aspect, a network component (e.g., BS, LMF, etc.) determines a configuration of a first search window associated with a downlink positioning reference signal (DL-PRS) resource from a transmission reception point (TRP) to a user equipment (UE) and a second search window associated with the DL-PRS resource from the TRP to the UE. The network component transmits the configuration to the UE. The UE performs one or more positioning measurements of the DL-PRS resources based on the first and second search windows.

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.
