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: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may determine a mobility state. The network node may determine a communication configuration, selected from a plurality of communication configurations associated with a plurality of mobility states, based at least in part on the mobility state. The network node may perform a communication procedure using the selected communication configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure are regarding configuring an Integrated Access and Backhaul (IAB) node of an IAB network to handle forwarding of packets from another device as well as packets originating in the IAB network at the IAB-node. An example method includes retrieving, by a Backhaul Adaptation Protocol (BAP) layer of the IAB-node, a packet from an upper layer or a Radio Link Control (RLC) layer of the IAB-node. The method also includes determining an egress RLC channel of an egress backhaul (BH) link with a second device for transmitting the first packet based on a first configuration in response to retrieving the first packet from the RLC layer or a second configuration in response to retrieving the first packet from the upper layer. The method also includes transmitting the first packet to the second device via the egress RLC channel of the egress BH.

Abstract: Aspects relate to a physical cell identifier (PCI) change within a wireless network based on a primary synchronization signal (PSS) waveform. A scheduling entity, such as an integrated-access-backhaul (IAB) node within a radio access network (RAN), may communicate with a set of one or more scheduled entities, such as other IAB nodes and/or user equipment (UEs), utilizing a first PCI. The scheduling entity may then change from the first PCI to a second PCI, where the second PCI corresponds to a different PSS waveform than the first PCI. In some examples, the scheduling entity may change the PCI as a result of a PCI collision and/or PSS collision with a neighboring scheduling entity.

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: The systems and methods described herein support efficient SDM operation in IAB networks. A first node receives a semi-static resource allocation from a CU based on at least one multiplexing capability of the first node. The first node communicates with a second node based on the semi-static resource allocation. The first node also transmits a change request to the CU to modify the semi-static resource allocation, and the first node may communicate with the second node based on the modified semi-static resource allocation. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node transmits a report to a CU, where the report includes at least one multiplexing capability or condition of the first node. The first node receives a semi-static resource allocation from the CU based on the at least one multiplexing capability, and the first node communicates with a second node based on the semi-static resource allocation. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

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.
