Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a beam failure detection reference signal (BFD-RS). The UE may determine, autonomously at the UE based at least in part on the BFD-RS, a beam failure instance (BFI) count for different types of BFI including BFI noise and BFI interference. The UE may detect a beam failure based at least in part on the BFI count satisfying a threshold. Numerous other aspects are described.

The systems and methods described herein support efficient SDM operation in IAB networks. A first node receives a semi-static resource allocation from a CU based on at least one multiplexing capability of the first node. The first node also receives from the CU one or more resource conditions for using allocated resources of the semi-static resource allocation, and the first node communicates with a second node based on the semi-static resource allocation and the one or more resource conditions. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

Certain aspects of the present disclosure provide techniques for over-the-air synchronization of integrated access and backhaul communications. An example method that may be performed by a network entity includes receiving, from a first wireless node, an indication of a value of a timing adjustment factor associated with a communication between the first wireless node and a second wireless node and communicating with the first wireless node or the second wireless node based on the value of the timing adjustment factor.

Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme. Such a beamformed formed narrowband communications scheme may be used for narrowband downlink shared channel communications, narrowband downlink control channel communications, or combinations thereof. In some cases, beamformed communications may be configured on a different carrier than the first carrier. The base station and UE may then communicate using beamformed transmissions.

Altitude based device management is provided herein. A method can comprise transmitting, by a mobile device comprising a processor, a signaling message to a network device of a wireless network. The signaling message can comprise first data indicating a device type of the mobile device and second data indicating a distance measurement of the mobile device with respect to a reference point. The method can also comprise implementing, by the mobile device, a first instruction related to a power setting and a second instruction related to an operating parameter. The first instruction and the second instruction can be received from the network device and can be based on the device type of the mobile device and the distance measurement of the mobile device.

Embodiments include methods for a user equipment (UE) to advertise capabilities to a network node in a radio access network. Embodiments include transmitting, to the network node, information describing a plurality of feature sets supported by the UE. The information can include one or more InitialFeatureLists and one or more ExtensionFeatureLists, with each each ExtensionFeatureList being associated with a particular InitialFeatureList. Embodiments also include transmitting, to the network node, one or more BandCombination elements, each including a list of frequency bands in which the UE is concurrently operable and a FeatureSetCombination element identifying features supported by the UE within each frequency band included in the list. Some embodiments can also include receiving, from the network node, a configuration (e.g., for dual connectivity and/or carrier aggregation) based on the information describing a plurality of feature sets and the BandCombination elements. Other embodiments include complementary methods performed by a network node.
