Abstract: Certain aspects of the present disclosure provide techniques for improving positioning accuracy of user equipments (UEs) using non line-of-sight (NLOS) positioning reference signals (PRS) and map information. A method that may be performed by a UE includes obtaining map information regarding, at least, one or more reflectors in an environment including at least the UE and another node, detecting at least one positioning reference signal (PRS) transmission that travels one or more non line-of-sight (NLOS) transmission paths in the environment, and participating in a positioning procedure that estimates a position of the UE based, at least in part, on the at least one PRS transmission that travels the one or more NLOS transmission paths and the map information.

Abstract: Aspects presented herein may enhance the configuration of the scheduling offset for communication devices within a channelized frequency band. In one aspect, a UE receives a PDCCH including a scheduling offset parameter. The PDCCH schedules one of a PDSCH for reception in a first sub-band within a BWP or provides an uplink scheduling grant of a PUSCH for transmission in a second sub-band within the BWP. The UE communicates with a base station based on one of a slot for receiving the PDSCH based on the first sub-band within the BWP and the scheduling offset parameter when the PDCCH schedules the PDSCH, or a slot for transmitting the PUSCH based on the second sub-band within the BWP and the scheduling offset parameter when a PUCCH is used to schedule the PUSCH.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE. In some aspects, the apparatus may determine a timing synchronization procedure with at least one sidelink UE. The apparatus may also configure a timing synchronization signal associated with the timing synchronization procedure, the timing synchronization signal including at least one of a signal bandwidth or a signal location. The apparatus may also transmit, to the at least one sidelink UE, the timing synchronization signal associated with the timing synchronization procedure.

Abstract: The present disclosure relates to wireless communication in mmW networks. The apparatus may be a base station. The apparatus may be configured to determine a first symbol index and a second symbol index associated with downlink resources allocated to a UE. The first symbol index may indicate when the downlink resources begin in a subframe, and the second symbol index may indicate when the downlink resources end in the subframe. The apparatus may be configured to transmit an indication of the first symbol index and the second symbol index to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a restriction on a combination of frequency components permitted to be used by the UE for carrier aggregation or frequency hopping, wherein the restriction indicates at least two frequency components that are not permitted to be combined for carrier aggregation or frequency hopping. The UE may communicate based at least in part on the restriction. Numerous other aspects are provided.

Abstract: In an aspect, first and second UEs each detect a target associated with a deflection point for a transmission beam from a BS to the respective UE, and each transmit, to the BS, information associated with the target. The BS transmits STRS configuration information to the first and second UEs. The BS multicasts, to the first and second UEs, an STRS on the transmission beam in accordance with the STRS configuration information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a set of frequency components for carrier aggregation and that indicates multiple sets of channel state information reference signals (CSI-RSs) or sounding reference signals (SRSs), wherein different sets of CSI-RSs or SRSs, of the multiple sets of CSI-RSs or SRSs, correspond to different subsets of frequency components included in the set of frequency components. The UE may monitor for one or more CSI-RSs or SRSs, corresponding to a subset of frequency components included in the set of frequency components, based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Techniques are provided for single sided beam management in a millimeter wave (mmW) communication system for use in bistatic radio frequency (RF) sensing. An example method of tracking targets with bistatic radio frequency sensing includes receiving a scanning reference signal, generating a scanning signal report indicating one or more target groups associated with the scanning reference signal, transmitting the scanning signal report, receiving tracking signal configuration information indicating a tracking reference signal associated with the one or more target groups, receiving the tracking reference signal identified in the tracking signal configuration information, and tracking the one or more target groups associated with the tracking reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.
