Abstract: Methods, systems, and devices for mobile integrated access and backhaul procedures based on interface availability are described. Some examples may provide approaches for blocking at least a portion of mobile Integrated Access and Backhaul (IAB) procedures when Xn connectivity is unavailable. Some aspects of the techniques may be performed in the context of mobile IAB node integration. For example, a second central unit (CU) may determine if Xn connectivity is available with a first CU. In a case that Xn connectivity is unavailable, the second CU may reject an F1 connection setup request or the second CU may accept the F1 connection setup request and trigger a DU migration to a different CU. Some aspects of the techniques may be performed in the context of mobile IAB-mobile termination (MT) migration. Some aspects of the techniques may be performed in the context of mobile IAB-distributed unit (DU) migration.

Abstract: A method for wireless communication by a user equipment (UE) includes receiving, from a network node, a first message indicating one or more parameters associated with a limited mobility zone within a coverage area of one or more cells. The method also includes transmitting, to the network node, a second message indicating the UE is within the limited mobility zone in accordance with determining the UE is within the limited mobility zone in accordance with the one or more parameters. The method further includes receiving, from the network node, a third message including first paging information in accordance with a first paging configuration associated with the limited mobility zone.

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: Aspects of the disclosure are directed to a lower layer split for a radio access network (RAN) node. In some examples, the number of tiers for the user plane path may be reduced from three to two, which may include redistribution of functionality of a central unit user plane (CU-UP) between two network entities. In some examples, a first network entity of the two network entities may be configured to receive, from a second network entity of the two network entities, a first user plane protocol data unit (UP-PDU) associated with a user plane (UP) protocol session. In some examples, the first UP-PDU includes a first identifier configured to identify the tunnel, a second identifier configured to identify the first flow of UP-PDUs, a third identifier configured to identify the first UP-PDU within the first flow of UP-PDUs, and a first data for transmission to a user equipment (UE).

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: Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a central unit (CU) and a distributed unit (DU) to communicate information for a network energy savings (NES) related conditional handover (CHO). For example, the CU, which may configure one or more user equipments (UEs) for the CHO, may indicate which UEs are configured to the DU, which may serve the UEs via Layer-1 (L1) signaling. The CU may further indicate which of the configured UEs are to perform the NES related CHO, which may be determined according to measurement reports from the configured UEs. In some examples, the DU may trigger the NES related CHO for UEs associated with measurement reports that satisfy an NES-specific threshold value, which may support the CU and the DU transitioning to the NES mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first random access channel (RACH) procedure with a serving cell of the UE. The UE may receive, prior to terminating the first RACH procedure, a trigger for a second RACH procedure with a candidate cell of the UE. The UE may initiate the second RACH procedure with the candidate cell. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method of wireless communication at a first distributed unit (DU), generally including detecting a condition related to a cell switch of a user equipment (UE) that supports dynamic mobility signaling via physical (PHY) layer or medium access control (MAC) layer signaling, wherein the condition is detected while a first data path between a centralized unit (CU) and the UE via the first DU is active and transmitting, based on detection of the condition, an indication to trigger the CU to begin forwarding data to the UE via a second data path involving a second DU involved in the cell switch.
