Abstract: Methods, systems, and devices for wireless communications are described. A first device may receive a message indicating a configuration for performing an energy harvesting procedure. The configuration may indicate a pairing of a component carrier and a bandwidth part for the first device to use for performing the energy harvesting procedure. The pairing may be based on one or more measurements associated with the first device. As part of the energy harvesting procedure, the first device may monitor for one or more signals from a second device. The first device may monitor for the one or more signals using a set of resources that correspond to the pairing of the component carrier and the bandwidth part. The first device may receive, from the second device, one or more signals using the set of resources.

Abstract: In some implementations, a ultra-wideband (UWB) device comprises a Global Anchor for a network of UWB anchors having a plurality of clusters and initiator anchors (Init-Anchors). The Global Anchor may obtain metric information comprising a centrality metric value of each Init-Anchor from information communicated to the Global-Anchor in a first control phase. The Global Anchor may determine a slot schedule for a second control phase, wherein: determining the slot schedule is based on the centrality metric values of the plurality of Init-Anchors; the slot schedule comprises an allocation of time slots of the second control phase among the plurality of Init-Anchors for wireless radio frequency (RF) communication; and the allocation of time slots includes a first set of time slots for upstream communication followed by a second set of time slots for downstream communication. The Global Anchor may send the slot schedule to an Init-Anchor of the plurality of Init-Anchors.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity determines a location of a target base station and a location of at least one reference device, determines an angle-of-arrival (AoA) measurement of one or more reference signals received by at least one antenna array of the target base station from the at least one reference device, determines an expected AoA between the at least one antenna array and the at least one reference device based on the location of the target base station and the location of the at least one reference device, and determines an orientation offset of the at least one antenna array based on a difference between the expected AoA and the AoA measurement.

Abstract: According to embodiments herein, the use of an SL interface in the positioning of a UE can include additional reporting from the UE or an anchor UE related to a reference signal sent via the SL interface. This information can include information regarding the received power and/or timing of the reference signal, the angle at which it was received, and orientation of a receiving UE, and various other considerations that may not be needed in a Uu interface with a base station.

Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the pre-configuration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.
