Abstract: Aspects relate to enhancing the provision of gaps at transitions between resources allocated for communication on access links and resources allocated for communication on backhaul links. In some examples, a child integrated access backhaul network (IAB) node may transmit a message to a parent IAB node requesting a number of guard symbols to provide a gap at transitions. In some examples, the parent IAB node may transmit the number of guard symbols provided at transitions to the child IAB node. The parent IAB node, child IAB node, and/or an IAB donor node central unit may further identify a subcarrier spacing associated with the number of guard symbols.

Abstract: Aspects relate to using different paging techniques for different sets of scheduled entities. In some examples, different paging message configurations are assigned to different sets of scheduled entities. In some examples, different paging resources are assigned to different sets of scheduled entities. In some examples, different paging-radio network temporary identifiers (P-RNTIs) are assigned to different sets of scheduled entities. In some examples, different SI modification fields indicate SI changes for different sets of scheduled entities. In some examples, different sets of scheduled entities use different paging search spaces. In some examples, different sets of scheduled entities use different paging parameters.

Abstract: Certain aspects of the present disclosure provide techniques for mobility-aware access control. A method that may be performed by a first wireless device generally includes receiving one or more signals from a second wireless device in the network, wherein the one or more signals provide an indication of a mobility state corresponding to the second wireless device; determining whether to establish a connection with the second wireless device based, at least in part, on the indication of the mobility state corresponding to the second wireless device; and taking one or more actions based on the determination. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, from a control node, information identifying a slot configuration pattern for a wireless communication link between the wireless node and another wireless node. For example, the information identifying the slot configuration pattern may indicate one or more symbols that are configured to support full-duplex communication. The wireless node may communicate with the other wireless node in the one or more symbols configured to support full-duplex communication in accordance with the slot configuration pattern. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node may configure first and second backhaul radio link control (RLC) channels based on requests received from a first integrated access and backhaul (IAB) donor central unit (CU) and a second IAB donor CU, respectively. The parent node may select first and second logical channel identifiers for the first and second backhaul RLC channels, the second logical channel identifier being different from the first logical channel identifier, and may provide the first and second logical channel identifiers to the first IAB donor CU and the second IAB donor CU, respectively. The parent node may receive a packet including either the first logical channel identifier or the second logical channel identifier, and process the packet based on which of the first and second logical channel identifiers is included in the packet. Other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

Abstract: Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by an Integrated Access and Backhaul (IAB) node is above a minimum value specified by a standard. In some cases, the IAB node may signal information regarding its power configuration so a network entity of the IAB may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the IAB node and/or an indication of a guard band that may help the IAB node control adjacent channel leakage.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may determine a set of resources that is unavailable for use by a distributed unit (DU) of the CU, the set of resources including one or more resources. The CU may transmit information identifying the set of resources that is unavailable for use by the DU to cause an inferior node of the DU to refrain from using the set of resources that is unavailable for use by the DU. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described to coordinate information across a wireless network. One or more access nodes of a wireless network may configure a time resource container for receiving, amplifying, and forwarding a signal, such as a notification signal, in an operating mode. A notification signal may include an indication of coordination information and may be transmitted or received in the time resource container, such as in a first subset of a set of time resources of the time resource container. An access node may first receive a signal from a second access node, amplify and forward the signal in the time resource container to a third access node, and then decode the received signal and determine whether the signal includes coordination information for the access node. If the signal includes coordination information for the access node, the access node may perform one or more actions.

Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.
