Abstract: Disclosed are techniques for communication. In an aspect, gNB may report antenna configuration and table that maps antenna element(s) to phase shift and/or amplitude shift to a position estimation entity (PDE). The PDE may derive beam shape based on the reported information. In another aspect, gNB may report transformation information by which a first beam shape of a first beam is transformed into a second beam shape of a second beam. The PDF may derive the second beam shape of the second beam based in part upon the transformation information.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a first network node performs a reception-to-transmission (Rx-Tx) time difference measurement, the Rx-Tx time difference measurement representing a difference between a reception time of at least one first positioning reference signal (PRS) from a second network node and a transmission time of at least one second PRS to the second network node, and transmits, to a positioning entity, based on a value of the Rx-Tx time difference measurement being greater than a threshold, a measurement report including a first value and a second value representing the value of the Rx-Tx time difference measurement, wherein the first value is a quotient value resulting from dividing the value of the Rx-Tx time difference measurement by the threshold, and wherein the second value is a remainder value resulting from dividing the value of the Rx-Tx time difference measurement by the threshold.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives positioning assistance data from a location server, the positioning assistance data including at least a first expected measurement value and a first expected measurement uncertainty value defining a first search window during which the UE is expected to measure a first plurality of positioning reference signal (PRS) resources transmitted by a first transmission-reception point (TRP), determines a best symbol hypothesis that is common to a first set of PRS resources of the first plurality of PRS resources, wherein the best symbol hypothesis is a symbol within the first search window during which a signal strength of each PRS resource of the first set of PRS resources is maximized, and measures each PRS resource of a second set of PRS resources of the first plurality of PRS resources only during the best symbol hypothesis.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide managing transmissions of sidelink positioning reference signals (PRS) with a timing advance offset (TA) from a sidelink node. In aspects, a sidelink node (e.g., a target user equipment (UE) or an assisting UE) may receive transmissions from a plurality of nodes (e.g., target UEs or assisting UEs). The sidelink node obtains at least one TA to be used by a transmitting node of the plurality of nodes for transmitting a sidelink PRS to the sidelink node (e.g., to advance the sidelink PRS transmission to the sidelink node with respect to the timing of the first transmission). The TA is an offset obtained by the sidelink node based on the receiving times of the transmissions from the plurality of nodes. The sidelink node may receive PRS transmissions from the plurality of nodes in a same symbol aligned within the same CP.

Abstract: A user equipment (UE) obtains assistance data for positioning from one or more sidelink connected UEs. Prior to sending the assistance data for positioning to the UE, the sidelink UE(s) revises the assistance data, e.g., by reprioritizing, reordering, or reducing the assistance data, or a combination thereof. By revising the assistance data the sidelink UE(s) provides the most pertinent assistance data to the UE, thereby increasing power savings for the UE. Where multiple sidelink UEs provide revised assistance data to the UE, the UE combines the revised assistance data, e.g., based on measurement information, range information, or priority of the sidelink UEs. If the UE has a connection to the location server, the UE obtains revised assistance data from sidelink UE(s) to avoid the need for an assistance data exchange with the location server during the positioning session, thereby improving latency.
