Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless node (e.g., gNB or UE) transmits, to a UE, a grant of a set of resources for a first communication between the UE and the wireless node. The wireless node further transmits, to the UE, a conditional grant associated with a set of conditional parameters for a second communication that overrides the grant for some or all of a subset of the set of resources. The UE and/or the wireless node detects a triggering event or an indication of the triggering event for triggering the conditional grant with at least one conditional parameter of the set of conditional parameters. The UE and the wireless node perform the second communication in accordance with the at least one conditional parameter on some or all of the subset of resources based on the detection.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the disclosure relate to enhanced load reporting between network entities (e.g., provided by a distributed unit (DU) to a centralized unit (CU) or by a CU to another CU). In some examples, the CU may provide one or more triggering events which may be used by the DU (or a second CU) to trigger the provisioning of a load report to the CU. Accordingly, the DU (or second CU) may be able to initiate a load report without relying on periodic reporting criteria. In some examples, the DU may initiate a load report to the CU without being configured with triggering events. In some examples, a DU may report measurements made associated with a communications load involving communications with both a parent network entity (e.g., a CU) and at least one child network entity (e.g., a user equipment).

The mobile IAB node may also indicate to the IAB supported network a mobility status associated with the mobile IAB node. The IAB supported network may conditionally determine authorization for the mobile IAB node based on the mobility status, a subscription status, or both. The IAB supported network may transmit, to the mobile IAB node, instruction to operate in an IAB mode and perform the IAB operation. The mobile IAB node may communicate with one or more devices based on the instruction.

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: In certain aspects, the disclosure is directed to a user equipment (UE) configured for wireless communications with a network node. The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the UE may transmit, to a network node, an indication of an expected communication. In some examples, the UE may receive, from the network node, updated scheduling in response to the indication of the expected communication. For example, the UE may predict a future sidelink/uplink communication based on whether the UE expects data for a future uplink transmission. If the UE expects that it will have data for a future uplink transmission, the UE may notify the network node so that the network node can enter into a low power state until the future transmission, then provide the UE with a sidelink/uplink grant for the future uplink transmission.
