Abstract: Method and apparatus for sharing dynamic capability levels of calibration to other devices in a network. The apparatus transmits, to a second UE, a first calibration capability message indicating a first set of one or more levels of calibration capabilities. The apparatus performs an online calibration procedure with the second UE based at least on the first calibration capability message indicating the first set of one or more levels of the calibration capabilities. The apparatus may receive, from the second UE, a second calibration capability message associated with the second UE indicating a second set of one or more levels of the calibration capabilities for the second UE. The apparatus may transmit a beamforming loss indication indicating a loss in beamforming array gain with use of an uncalibrated amplitude or phase settings corresponding to at least one of an operating frequency, a temperature level, or a gain stage level.

Abstract: Aspects of the disclosure are directed to transmission configuration indicator (TCI) configuration of a component carrier (CC). For example, aspects are directed to aligning TCI configurations and physical cell identifier (PCI) lists between multiple CCs. Some examples include receiving, from a serving cell, a first TCI configuration for a first CC, wherein the first TCI configuration comprises a first TCI pool comprising at least one TCI state mapped to one of a PCI of the serving cell or a PCI index corresponding to a neighboring non-serving cell. Examples may also include communicating wireless signaling between a user equipment (UE) and the serving cell via a second CC using the at least one TCI state of the first TCI pool.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on synchronization signal blocks (SSB) in a network (e.g., an Integrated Access and Backhaul (IAB) network. In some cases, a node determines resources used for periodic SSB transmissions by at least one parent node of the network, uses the determined resources to perform SSB-based interference measurements, and communicates with at least one of the parent node, a central unit (CU), or another node of the network based on the SSB-based interference measurements.

Abstract: Apparatus, methods, and computer-readable media for facilitating a programmable smart repeater with in-band control are disclosed herein. An example method for wireless communication at a repeater includes establishing a control link with a control node and receiving, via the control link, a configuration for the repeating unit component of the repeater to forward communication between a first wireless device and a second wireless device on an access link. The example method also includes transitioning an MT component of the repeater to an RRC inactive mode or an RRC idle mode for at least a period of time after receiving the configuration and forwarding the communication between the first wireless device and the second wireless device on the access link based on the configuration while the MT component of the repeater is in the RRC inactive mode or the RRC idle mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an interference threshold for interference caused by beamforming at the UE. The UE may transmit a signal using a beam with an interference value that satisfies the interference threshold. Numerous other aspects are described.

Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for downlink control information format for indication of transmission configuration indication state. A user equipment may receive, from a base station, downlink control information (DCI); determining whether the DCI is used for beam indication with or without downlink assignment. The UE also may apply transmission configuration indication (TCI) states based on TCI codepoints in a TCI field of the DCI, when the DCI is used for beam indication. The base station may generate the DCI with information indicating whether the DCI is intended for beam indication with or without downlink assignment, in which the DCI includes the TCI codepoints to apply the TCI states at the UE when the information in the DCI indicates that the DCI is intended for beam indication. The base station may transmit, to the UE, the DCI.

Abstract: A first wireless device and a second device may negotiate a configuration of an RF chain calibration process with each other. The configuration of the RF chain calibration process may include a number of calibration rounds. The second wireless device may exchange, in each calibration round in the number of calibration rounds, at least one RS and at least one feedback message with the first wireless device. The second wireless device may identify one or more calibration adjustment parameters for the second wireless device based on the RF chain calibration process. The second wireless device may communicate with another wireless device based on the one or more calibration adjustment parameters.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a configuration of multiple application time values for transmission configuration indication (TCI) state updates. The UE further receives downlink control information (DCI) in a control resource set (CORESET) associated with a first CORESET pool index associated with a first transmission reception point (TRP) and including a transmission configuration indication (TCI) state associated with a second CORESET pool index associated with a second TRP. The UE further transmits acknowledgement/negative acknowledgement (ACK/NACK) feedback to one or more TRPs based on a feedback mode configured for the UE, and applies the TCI state indicated in the DCI following the ACK/NACK feedback based on one of the multiple application time values and the feedback mode.
