A signal measuring method includes: receiving, at a user equipment, first positioning assistance data having a first area of applicability and a first positioning assistance data profile; storing the first positioning assistance data at the user equipment; determining, at the user equipment, that second positioning assistance data correspond to the first positioning assistance data based on the first area of applicability including a second area of applicability, of the second positioning assistance data, and based on a second positioning assistance data profile of the second positioning assistance data corresponding to the first positioning assistance data profile; and measuring, at the user equipment, a positioning signal corresponding to the second area of applicability using the first positioning assistance data in response to determining that the second positioning assistance data correspond to the first positioning assistance data.

Regional positioning assistance data

In an embodiment, a wireless node (e.g., UE or BS) receives from a network component (e.g., BS or core network component) a request for a positioning estimate of a UE associated with a specified time. The wireless node performs positioning measurements at a plurality of times, and determines (e.g., via interpolation or extrapolation) the positioning estimate associated with the specified time based on the positioning measurements. The wireless node transmits, to the network component, a report comprising the determined positioning estimate.

User equipment positioning estimate for specified time

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.

Signaling consideration for new radio positioning with disjoint bandwidth segments

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.

Supporting scheduling of sounding reference signals

An example method for distance-dependent positioning of a user device (UE) performed by a location server, the method comprising: sending, to a transmission/reception point (TRP), a first configuration for distance-dependent position reference signal (PRS) resource sets, the distance-dependent PRS resource sets comprising at least: a first PRS resource set for positioning the UE when an estimated distance between the UE and the TRP is within a first range interval. The method also comprises determining the estimated distance between the UE and the TRP, sending, to the UE, a second configuration for determining PRS measurements based on at least one PRS resource set of the distance-dependent PRS resource sets at the TRP, the at least one PRS resource set corresponding to the estimated distance between the UE and the TRP, and receiving, from the UE, the PRS measurements; and determining the position of the UE based on the PRS measurements.

Distance-dependent position reference signal (PRS) configuration

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam selection. In one aspect, an initiating wireless device may determine whether a pre-grant acknowledgement associated with a first beam has been received from a responding wireless device within an expected receive time. The initiating wireless device may generate an indication to prevent the initiating wireless device from using the first beam for a blocking duration in response to determining that the pre-grant acknowledgement associated with the first beam has not been received within the expected receive time.

Managing beam selection

In some implementations, a base device may determine a quali-colocation (QCL) relation between a first wireless reference signal transmitted by a first sidelink (SL) anchor and a second wireless reference signal transmitted by a second SL anchor, wherein: the first SL anchor and the second SL anchor comprise UEs separate from the receiving UE, and the first wireless reference signal and the second wireless reference signal are transmitted for positioning of the receiving UE, performing radio frequency (RF) sensing, or both. The base device may wirelessly send, from the base device to the receiving UE, the mSL-QCL information, wherein the mSL-QCL information is indicative of the QCL relation between the first wireless reference signal and the second wireless reference signal.
