Abstract: An integrated access and backhaul (IAB) apparatus transmits a set of values to a child IAB node corresponding to a transition type for the child IAB node, determines that the child IAB node will perform a transition at a transition time with a symbol adjacent to the transmission time having a flexible resource type, and provides a number of guard symbols at the transition time based on determining that the symbol has the flexible resource type.

Abstract: Methods, systems, and devices for wireless communications are described. A first node of an integrated access and backhaul (IAB) network may identify a second, neighboring non-parent node of the TAB network. The second node may be associated with a timing source which may provide more accurate timing information than the parent node of the first node. The first node may transmit a first random access message to the second node to initiate a random access procedure. The second node may transmit a second random access message to the first node, the second random access message including timing information based on the timing source. The first and second nodes may terminate the random access procedure based at least in part on receiving the second random access message.

Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node transmits a report to a CU, where the report includes at least one multiplexing capability or condition of the first node. The first node receives a semi-static resource allocation from the CU based on the at least one multiplexing capability, and the first node communicates with a second node based on the semi-static resource allocation. 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.

Abstract: Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on a priority value in a network (e.g., an Integrated Access and Backhaul (IAB) network). One example method generally includes determining, based on a priority level associated with each of a first wireless node, a second wireless node, or both, at least one configuration for communicating one or more synchronization signal blocks (SSBs) between the first wireless node and the second wireless node, each of the first wireless node and the second wireless node being configured to serve one or more child nodes, wherein the at least one configuration comprises information enabling the first wireless node or the second wireless node to manage interference to communications. In some aspects, the method may also include transmitting the at least one configuration to at least one of the first wireless node or the second wireless node.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media for beam switching by a repeater node that forwards communications from one of a first node or a second node to the other of the first node or the second node. For example, after a change of position by the second node, the first node may provide the repeater node an instruction to perform a beam change operation to communicate with the second node. In some aspects, performing the beam change operation by the repeater node may improve reliability of wireless communications, such as by focusing signal energy in a particular direction. Further, a beam change delay time interval or a scheduling of the beam change delay time interval may be selected based on scheduling associated with other nodes, which may reduce a number of messages sent to the repeater node (such as by reducing instructions to change beam directions).

Abstract: Methods, systems, and devices for wireless communications are described. A base station (e.g., a central unit (CU) function of the base station) may select, from a set of distributed units (DUs) associated with the CU, a DU of an integrated access and backhaul (IAB) node to control sidelink communications for a user equipment (UE). The base station may determine a configuration of sidelink parameters for the sidelink communications with the UE, the sidelink parameters comprising an identification of the selected DU. The base station may transmit, to the TAB node performing sidelink communications with the UE, an indication of the configuration of sidelink parameters for the sidelink communications.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous beamforming configuration change. A method that may be performed by a wireless node includes determining a communication mode to be used for communication by the wireless node, wherein the determining of the communication mode includes determining whether the communication is associated with multiple simultaneous communications with one or multiple other wireless nodes. The method may also include determining a beamforming configuration to be used for the communication based on the communication mode, and communicating in accordance with the communication mode using the beamforming configuration.

Abstract: The present disclosure provides techniques for uplink resource management. For example, a method is provided including receiving a configuration granting a plurality of periodic uplink resources for use by the first wireless communication device to transmit data on an uplink. The method further includes determining for a first uplink resource of the plurality of periodic uplink resources, that grant of the first uplink resource for use by the first wireless communication device can be released. The method further includes based on the determining for the first uplink resource, transmitting to a second wireless communication device an indication that the grant of the first uplink resource for use by the first wireless communication device can be released.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, mapping information indicating, for each bandwidth part (BWP) of multiple BWPs, a mapping between a respective beam direction of multiple beam directions and the BWP. The method further includes receiving an allocation of a first BWP. The method also includes communicating, via the first BWP, one or more first messages using a first beam having a first beam direction, and receiving, from the base station, a change indicator associated with a second BWP or a second beam direction. The method includes communicating, via the second BWP, one or more second messages using a second beam having a second beam direction. Other aspects and features are also claimed and described.
