Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a mapping between a set of synchronization signal block resources and a set of operating frequencies within a frequency band. The UE may identify a parameter of a synchronization signal block based on an operating frequency of the set of operating frequencies for conveying the synchronization signal block and a direction of a beam for conveying the synchronization signal block. The parameter may include an index of the synchronization signal block. The UE may monitor for the synchronization signal block based on the identified parameter.

Abstract: A user equipment (UE) associated with a wireless network determines a first reference signal time difference value. The UE determines a first RSTD estimate and a first RSTD uncertainty associated with the first RSTD value, identifies a search interval for the first RSTD value, the search interval extending from a difference between the first RSTD estimate and the first RSTD uncertainty to a sum of the first RSTD estimate and the first RSTD uncertainty, receives wireless signals during the identified search interval, determines a Fast Fourier Transform (FFT) window offset for decoding a first positioning reference signal (PRS) received during the identified search interval, and determines the first RSTD value based at least in part on the determined FFT window offset.

Abstract: 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.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station (BS) transmits, to a user equipment (UE), a first configuration of a first radio access network notification area (RNA) associated with paging of the UE while the UE is in an radio resource control (RRC) INACTIVE state, the first RNA comprising a first set of cells. In a further aspect, the BS transmits, to the UE, a second configuration of a second RNA associated with positioning of the UE while the UE is in the RRC INACTIVE state, the second RNA comprising a subset of the first set of cells.

Abstract: In an aspect, a network entity transmits, to a UE, a PRS configuration that configures a plurality of PRS measurement occasions (MOs)) of one or more PRS resources associated with a transmission reception point (TRP), wherein each PRS MO is transmitted on a different time instance on the same bandwidth. The UE performs one or more measurements at each of the plurality of PRS MOs of the same PRS resource of the one or more PRS resources. The UE transmits, to the network entity, a single measurement report comprising measurement information associated with the one or more measurements derived on the same PRS resource from two or more of the plurality of PRS MOs.

Abstract: In an aspect, a wireless node (e.g., UE or BS) determines timing information associated with a first one or more reference signals for positioning or with a first one or more measurements derived using the first one or more reference signals for positioning, the first timing information including a transmit or receive hardware group delay, timing error, timing calibration error, or a combination thereof. The wireless node further determines that the first one or more reference signals or the first one or more measurements are associated with one of a plurality of timing groups at least based on the first timing information. The wireless node transmits (e.g., to a position estimation entity) an indication of the associated timing group in association with the first one or more reference signals for positioning or with the first one or more measurements derived using the first one or more reference signals for positioning.
