Abstract: An integrated access and backhaul (IAB) node may establish a first connection with a first base station, establish a second connection with a second base station, and receive an indication, from the first base station or the second base station, that indicates at least one of the first base station or the second base station is to serve as an IAB donor for the IAB node. The first base station may indicate to the second base station, based on the second connection being established with the IAB node, that at least one of a first base station or the second base station is to serve as an IAB donor for the IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, via a first interface of a repeater, information associated with a second interface of the repeater. The base station may determine a configuration for the second interface of the repeater based at least in part on the information associated with the second interface, and may communicate the configuration for the second interface of the repeater via the first interface. In some aspects, a repeater may transmit, to a base station via a first interface, information associated with a second interface of the repeater. The repeater may receive, via the first interface, a configuration for the second interface, and may configure the second interface based at least in part on the configuration. Numerous other aspects are provided.

Abstract: A method of wireless communication by an integrated access and backhaul network (IAB) donor transmits a configuration message on a source path to a first IAB node via a first distributed unit of the IAB donor. The method also instructs the first IAB node to delay delivery of the configuration message to a second node. The method migrates at least part of communications to the first IAB node from the source path to a target path via a second distributed unit. Another method of wireless communication is executed by a first integrated access and backhaul network (IAB) node. The method receives a first configuration message over a source path to a first IAB donor via a first distributed unit of the first IAB donor. The method also delays delivery of the first configuration message to a second node until a trigger occurs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may detect and report blockage conditions based on measuring signal strengths of reference signals. A UE may determine a slew rate for the signal strength, corresponding to a rate of change of a signal strength parameter (e.g., a reference signal received power (RSRP) or a received signal strength indicator (RSSI)) with respect to time, and report the slew rate to a base station to indicate signal strength degradation (e.g., due to a blockage). In some examples, the UE may define multiple slew rates associated with different rates of change of the signal strength parameter with respect to time. When the UE crosses a level of slew rate, the UE may indicate this to the base station to initiate mitigation procedures. In some examples, the techniques described herein may be extended to reporting slew rates for multiple beams.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an insufficient calibration message based at least in part on a trigger condition that indicates that a calibration of the wireless communication device is insufficient. The wireless communication device may receive a set of signals associated with calibration assistance in response to the insufficient calibration message. Numerous other aspects are described.

Abstract: A dual-polarized multiple-input-multiple-output (MIMO) mobile device is provided that includes a first array of antennas and a second array of antennas. Based upon a blockage of at least one of the array of antennas being less than a blockage threshold, the mobile device operates in a default configuration in which a default polarization selection from the second array is used in combination with a fixed polarization selection from the first array to form a first MIMO layer signal and a second MIMO layer signal. Should the blockage exceed the blockage threshold and an optional performance threshold be satisfied, the mobile device may operate in a dynamic configuration in which a dynamic polarization selection from the second array is reversed as compared to the default polarization selection.

Abstract: In an aspect, a user equipment (UE) may receive positioning assistance data from a location server, wherein the positioning assistance data identifies one or more first positioning reference signal (PRS) resources for measurement by the UE during a positioning session between the UE and a location server. The UE may receive post-measurement positioning assistance data from at least one sidelink device located within a threshold distance to the UE, wherein the post-measurement positioning assistance data received from the at least one sidelink device is based on measurements of one or more second PRS resources obtained by the at least one sidelink device during a positioning session of the at least one sidelink device. The UE may selectively measure at least a subset of the one or more first PRS resources based on the post-measurement positioning assistance data received from the at least one sidelink device.
