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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may identify one or more resources for transmitting one or more synchronization signal blocks (SSBs), the one or more resources being associated with a mobility state of the IAB node. The IAB node may transmit the one or more SSBs in the one or more resources. Numerous other aspects are provided.

Abstract: When moving within an area covered by an Integrated access and backhaul (IAB) network, a mobile IAB node may come into proximity with another stationary or mobile IAB node that may have a same physical cell identifier (PCI) as the mobile IAB node. PCI collision issue may occur. Aspects presented herein address the possible PCI collisions. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node configured to determine a configuration associated with PCI management of a PCI of the IAB node. The apparatus may be further configured to change the PCI of the IAB node based on the determined configuration.

Abstract: Aspects relate to a soft physical cell identifier (PCI) change within a wireless network. A scheduling entity may communicate with a set of one or more scheduled entities within a first cell utilizing a first PCI. The scheduling entity may determine that a second PCI of a second cell co-located with the first cell has been assigned to the scheduling entity, for example, as a result of a PCI collision. The scheduling entity may implement a soft PCI change from the first PCI to the second PCI during a transition period within which the set of one or more scheduled entities may be transferred from the first cell to the second cell. The scheduling entity may then discontinue using the first PCI after completion of the transition period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (LAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second LAB donor CU. The IAB node may establish the first connection with the second parent DU. The LAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may transmit, to a second WCD, information associated with a power spectral density (PSD), the information including a PSD range that may be used to transmit a communication. The WCD may transmit, to the second WCD, the communication based at least in part on the transmission of the information. Numerous other aspects are described.

Abstract: Techniques for using simultaneous connectivity for mobility of integrated access and backhaul nodes may include an IAB node establishing a first connection with a first parent node (e.g., second IAB node) associated with a first IAB donor device (e.g., first base station) and establishing a second connection with a second parent node (third IAB node), wherein the second connection is simultaneous with the first connection. The IAB node may also switch the first connection from the first parent node to the second parent node. In doing so, the IAB node may have dual connectivity with the second parent node, where one connection is a master connection and the other connection is a secondary connection.

Abstract: A configuration for local coordination between the child node and parent node to enable SDM communication between the parent and child node, without input or interaction from the CU. The apparatus receives, from a CU, an indication including an allocation of resources. The apparatus determines a type of communication with a second node based on the allocation of resources. The apparatus communicates with the second node based on the determined type of communication and utilizing the allocated resources. The apparatus coordinates with a parent node to utilize the allocated resources in an SDM operation between the child node and the parent node.

Abstract: A second network node determines a backhaul adaptation protocol (BAP) configuration associated with a backhaul traffic transport and including a topology identifier corresponding to a topology of a plurality of topologies for which traffic associated with the topology is transported based on the BAP configuration. The second network node sends, to a first network node, the BAP configuration associated with the backhaul traffic transport. The first network node receives a first BAP configuration associated with a first topology identifier (ID) corresponding to a first topology, and a second BAP configuration associated with a second topology ID corresponding to a second topology that overlaps at least in part with the first topology. The first network node determines with which traffic is associated routes traffic associated with the first topology ID based on the first BAP configuration, and traffic associated with the second topology ID based on the second BAP configuration.
