Abstract: 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.

Abstract: Wireless communications systems and methods related to accessing a channel based on an interference condition in a wireless communication network are provided. For example, a method of wireless communication performed by a wireless communications device may include receiving, from a second wireless communication device, one or more signals associated with a beam parameter, determining, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals, and determining, based at least in part on a cumulative distribution of the signal measurements at the plurality of locations and a reference probability distribution, whether the second wireless communication device satisfies an interference condition. Other features are also claimed and described.

Abstract: A UE receives, from a BS, information indicating a first TEG delay at the BS for a transmission of a first PRS, a second TEG delay at the BS for a reception of an SRS from the UE, a third TEG delay at the BS for a transmission of a second PRS, a fourth TEG delay at the BS for a transmission of the first PRS and a reception of the SRS from the UE, or a fifth TEG delay at the BS for a reception of the SRS from the UE and a transmission of the second PRS, or any combination thereof. The UE determines a double RTT based on a first PRS timing associated with a reception of the first PRS, an SRS timing associated with a transmission of the SRS, a second PRS timing associated with a reception of the second PRS, and the received information.
