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.

Abstract: When moving within an area covered by an Integrated access and backhaul (IAB) network, a mobile IAB node may come into proximity with another stationary or mobile IAB node that may have a same physical cell identifier (PCI) as the mobile IAB node. PCI collision issue may occur. Aspects presented herein address the possible PCI collisions. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node configured to determine a configuration associated with PCI management of a PCI of the IAB node. The apparatus may be further configured to change the PCI of the IAB node based on the determined configuration.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and non-transitory computer readable medium for wireless communications for a donor node to provide a resource pattern over an integrated access and backhaul (IAB) backhaul. The aspect may include determining, at a central unit (CU) of the donor node, a configuration of a resource pattern for a plurality of IAB-nodes of an IAB network, wherein the configuration of the resource pattern includes a base resource pattern configured with a base periodicity of one or more slots and a plurality of distributed unit (DU) slot format indices within the base periodicity. The aspect may include transmitting, by the CU of the donor node, the resource pattern to one or more of the plurality of IAB-nodes of the IAB network.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish connectivity to a local area network using cellular radio access technology (RAT). The UE may establish a signaling radio link with a cellular access node (AN) via a cellular RAT. The UE may transmit a connectivity request to a network node via the signaling radio link. The connectivity request may specify a connectivity type for establishing connectivity to a LAN. Based at least in part on an acceptance of the connectivity request, the UE may establish a data radio link with the cellular AN. In an example, the acceptance of the connectivity request may include at least one parameter for configuring the connectivity to the LAN. The UE may then establish a data flow for exchanging data link layer packets with the LAN via the data radio link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may establish a first connection between a child wireless node and a first base station and a second connection between the child wireless node and a second base station, wherein the first connection is an F1-U direct path and the second connection is an F1-U alternative path. The wireless node may forward at least a portion of user-plane traffic between the child wireless node and the first base station via the second connection and the second base station. Numerous other aspects are described.

Abstract: A configuration for dynamically updating the neighbor list sent to a UE based on the location of the UE and the location of one or more mobile relays. The apparatus receives first location information for one or more UEs. The apparatus receives second location information for one or more mobile relays. The apparatus determines a distance between the one or more UEs and each of the one or more mobile relays. The apparatus sends assistance information to at least one of the one or more UEs in an area, the assistance information identifying at least one mobile relay of the one or more mobile relays based on the determined distance between the one or more UEs and the at least one mobile relay.

Abstract: The present disclosure relates to methods and apparatus for wireless communication of a first node. The apparatus can receive a first signal from a second node of one or more additional nodes, the first signal including at least one first timing reference. The apparatus can also determine a second timing reference quality of a second timing reference. The apparatus can also transmit a second signal to at least one node of the one or more additional nodes, the second signal including a second timing reference. Additionally, the apparatus can broadcast, to the one or more additional nodes, an indication of a second timing reference quality of the second timing reference. The apparatus can also receive an indication of a first timing reference quality. Moreover, the apparatus can adjust the indication of the quality of the at least one timing first reference from the second node.

Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. For example, in one aspect a wireless communication technique takes into account the load of a relay before a UE is switched from one relay to another. In another example, a wireless communication technique ensures that UEs are handed over to relays that will be able to serve the UE as the mobile relay continues to follow its expected path (such as streets or tracks), which may be known or determined.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.
