Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) positioning using one or more intelligent reflecting surfaces (IRSs). A method that may be performed by a UE includes for each IRS of the one or more IRSs: identifying a first IRS reflection center, measuring a first impulse response from the IRS to obtain a first measured impulse response representation, determining a first impulse response for a first ray reflected from the first IRS reflection center of the IRS, estimating a first position of the UE based on, at least, the first IRS reflection centers for each of the one or more IRSs and the first impulse responses for each of the one or more IRSs, and estimating a second position of the UE in an iterative manner until one or more conditions are satisfied.

Abstract: A node including an RU and a control entity is disclosed. The node may receive, from a base station at a control entity of the node, an indication of at least one obstruction for communication via at least one reflective surface. The indication may indicate to the control entity to utilize an RU of the node and the at least one reflective surface for communication. The node may configure, upon receiving the indication of the at least one obstruction, the RU and the at least one reflective surface for communication with the base station. The node may forward communication received from, or forward communication to, the base station via the RU and the at least one reflective surface based on the at least one obstruction for communication.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PDSCH rate-matching in NTN systems. A UE may receive an indication of a subset of one or more SSB beams included in a set of SSB beams having one or more PDCCH resources reserved for potentially scheduling one or more SIBs associated with the set of SSB beams. The UE may further receive a PDSCH associated with resources that overlap with at least a portion of the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams, and rate-match around the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams for receiving the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: A node including a non-planar reflective surface is disclosed. The node may receive, from a base station, an indication of a surface configuration of at least one convex reflective surface of the node. The indication may indicate that the surface configuration corresponds to at least one of a broadcast configuration or a UE-specific configuration. The node may configure, upon receiving the indication of the surface configuration, the at least one convex reflective surface based on the surface configuration. The surface configuration may correspond to at least one of the broadcast configuration or the UE-specific configuration. The node may forward communication received from, or forward communication to, the base station based on the surface configuration of the at least one convex reflective surface.

Abstract: Aspects of the present disclosure relate to utilizing an intelligent reflecting surface (IRS), a tracking algorithm, or both, to receive, calibrate, and maintain orbital angular momentum (OAM) signaling between wireless devices. The present disclosure describes a first wireless device transmitting spatial-multiple input-multiple output (MIMO) beams to the IRS such that reflected waves from the IRS form a spatial mixture of OAM modes. The IRS may reflect such OAM modes to a second wireless device for subsequent reflection (e.g., a second IRS), reception, calibration, and optimization. For example, the second wireless device may perform pattern recognition of the concentric OAM modes (e.g., by estimating ellipse geometry) to determine the modes of the OAM signaling. The second wireless device may also perform decorrelation, where small perturbations to the elliptical OAM geometry allow the second wireless device to perform one or more optimization techniques related to the OAM signaling.

Abstract: A node may identify a node configuration including one or more surface phase configurations associated with the node. In one configuration, the node may receive, from the base station, an indication of the node configuration. In another configuration, the node may select, at a controller associated with the node, the node configuration. The one or more surface phase configurations may be based on a wavelength corresponding to a center of a BWP associated with the one or more wireless signals or a wavelength corresponding to a center of a resource allocation associated with the one or more wireless signals. The node may forward, from a base station to a UE, or from the UE to the base station, one or more wireless signals. The forwarded one or more wireless signals may be associated with a beam squint less than a first threshold.

Abstract: Methods, systems, and devices for wireless communications are described to support using one of multiple types of synchronization signal blocks (SSBs) to perform one or more management procedures. A base station may configure and transmit one or more SSBs of second type that are smaller than SSBs of a first type. For instance, SSBs of a second type may include a first subset of signals and may exclude a second subset of the signals that are included in an SSB of the first type. An SSB of the second type may be transmitted in an active bandwidth region used for communications between a user equipment (UE) and the base station. The UE may receive an SSB of the second type in an active bandwidth region, may perform one or more measurements using the SSB of the second type, and may perform one or more management procedures.

Abstract: A base station may select a plurality of node parameters of a node including at least one of: a number of UEs that have accessed a network while the node is operational, an amount of information that has been communicated through the network while the node is operational, one or more QoS measurements while the node is operational, or one or more resources utilized for operation of the node. The base station may configure, upon selecting the plurality of node parameters, an access threshold for the node based on the plurality of node parameters. The base station may transmit, to the node, an indication of the access threshold for the node based on the plurality of node parameters. The node may configure, upon receiving the indication of the access threshold, access to the node for each of the number of UEs based on the access threshold.
