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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may transmit, to a second wireless node, a cross-link interference (CLI) management configuration message including a permutation indicator, wherein the permutation indicator indicates that an order of slot formats is an uplink-flexible-downlink order of slot formats or indicates that the order of slot formats is a downlink-flexible-uplink order of slot formats; and communicate with one or more third wireless nodes in accordance with the order of slot formats indicated to the second wireless node. Numerous other aspects are provided.

Abstract: Aspects relate to an integrated access backhaul (IAB)-Distributed Unit (DU) resource configuration framework for paired (e.g., frequency division duplex (FDD)) spectrum. Two DU resource configurations per cell may be supported for paired spectrum, including one for a first spectrum band (e.g., a downlink frequency band) and another for a second spectrum band (e.g., an uplink frequency band) of the paired spectrum. Each DU resource configuration may include a respective symbol pattern of symbol types (e.g., downlink (DL), uplink (UL), flexible) for a plurality of slots, as well as a corresponding availability attribute for each symbol type (e.g., hard, soft, or not available). A DU of an IAB node in an IAB network may receive the two DU resource configurations for the paired spectrum from a central unit (CU) of an IAB donor node in the IAB network.

Abstract: Aspects presented herein may enable an IAB node to modify a resource allocation or change one or more parameters related to the resource allocation when the IAB node detects that the resource allocation overlaps with guard symbols or another resource allocation. In one aspect, an IAB node determines that a first channel allocation will be punctured based on an overlap of the first channel allocation with at least one of a guard symbol or a second channel allocation. The IAB node uses, for the first channel allocation or the second channel allocation, one or more of a modified parameter or a modified grant in response to determining that the first channel allocation will be punctured.

Abstract: An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may identify one or more parameters indicating a mobility of a served node relative to a serving node. The wireless node may classify the served node within a category, among a plurality of categories, based at least in part on the one or more parameters. In some aspects, the plurality of categories may include at least a first category for served nodes that have a low mobility relative to the serving node and a second category for served nodes that have a high mobility relative to the serving node. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for interference coordination between wireless nodes (e.g., nodes of an Integrated Access and Backhaul (TAB) network). The techniques generally include determining, by a first wireless node, resources for sending an indication of interference coordination to a second wireless node, and sending the indication to the second wireless node using the determined resources, as part of an interference coordination procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity in an integrated access and backhaul (IAB) network may determine that a trigger condition for updating transport network layer information of an IAB node in the IAB network is satisfied, based at least in part on at least one of: a change of a donor distributed unit associated with the IAB node, a central entity change associated with the IAB node, or an establishment, release, or modification of a route including the IAB node; and provide, to the IAB node, updated transport network layer information, based at least in part on the trigger condition being satisfied. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node, a first message providing a first indication of integrated access and backhaul (IAB) capability. The first node may receive, from the second node and in response to the first message, a second message providing a second indication of IAB capability. The first node may establish an IAB capable connection with the second node based at least in part on the first message and the second message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, via a mobile termination (MT) and from a central unit (CU) of a donor network node, a first message that includes first information associated with a token. The network node may transmit, via a distributed unit (DU) and to the CU of the donor network node, a second message that includes second information associated with the token, to thereby indicate collocation of the MT and the DU. Numerous other aspects are provided.
