    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive mobility state information associated with an integrated access backhaul (IAB) node. The mobility state information may include information associated with at least one of: a level of mobility of the IAB node, or a change in mobility of the IAB node. The wireless communication device may perform an operation based at least in part on the mobility state information associated with the IAB node. In some aspects, a wireless communication device may determine that mobility state information associated with an IAB node is to be transmitted, and may transmit the mobility state information associated with the IAB node based at least in part on the determination. Numerous other aspects are provided.

    Abstract: Aspects of the present disclosure provide techniques for inter-donor topology discovery in an Integrated Access and Backhaul (IAB) network during migration of an IAB-node. A method that may be performed by a first IAB-donor includes establishing a first signaling connection with an IAB-node, receiving an indication that the IAB-node has a second signaling connection with a second IAB-donor, and in response to receiving the indication: transferring, to the second IAB-donor, information related to the IAB-node, re-establishing traffic between the first IAB-donor and the IAB-node via a topology of the second IAB-donor, or any combination thereof.

    Abstract: An integrated access and backhaul (IAB) donor central unit (CU) may transmit, to an IAB-node, a plurality of messages for a child of the IAB-node, the plurality of messages including a first message being associated with a first condition, and a second message being associated with a second condition, and transmit an indication instructing the IAB to forward, to the child, the first message if a first condition is met or the second message if a second condition is met. The IAB-node may receive, from the IAB-donor-CU, the indication, determine that one condition among the first condition and the second condition has occurred, forward one of the first message or the second message to the child based on the occurrence of the one condition, and discard the other of the first message or the second message.

    Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at an integrated access and backhaul (TAB) node. The TAB node receives a first delay parameter and a second delay parameter associated with a packet, the first delay parameter being associated with a discard determination for the packet and the second delay parameter being associated with scheduling the packet for transmission. The TAB node performs a discard decision for the packet based on the first delay parameter associated or schedules the packet for transmission to a second TAB node or a user equipment (UE) using a second delay parameter associated with the packet. A central unit (CU) of an TAB network may indicate, to an TAB node, the second delay parameter for scheduling a packet and the first delay parameter for determining whether to discard the packet.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, while connected to a first cell associated with a physical cell identifier (PCI) and a first cell global identifier (CGI), a message that includes an indication to connect to a second cell, associated with the PCI and a second CGI, responsive to detecting the second CGI in a system information message associated with the PCI. The wireless node may connect to the second cell based at least in part on detecting the second CGI in the system information message associated with the PCI. Numerous other aspects are provided.

    Abstract: Aspects of disclosure relate to a network node for changing a physical cell identifier (PCI). The network node transmits a first signal based on a first PCI during a first synchronization signal block (SSB) occasion, transmits a second signal based on the first PCI during a second SSB occasion, and transitions from the first PCI to a second PCI. During a transition period, the network node transmits the first signal based on the second PCI during the first SSB occasion, and continues to transmit the second signal based on the first PCI during the second SSB occasion. After an end of the transition period, the network node continues to transmit the first signal based on the second PCI during the first SSB occasion, and ceases transmission of the second signal based on the first PCI during the second SSB occasion. Other aspects and features are also claimed and described.
