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: 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: 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 node, such as a node in an integrated access backhaul (IAB) deployment, may receive information identifying a timing advance value and a timing assistance value, wherein the timing assistance value is associated with a configuration parameter. The node may perform a downlink transmission to a child node of the node based at least in part on the timing advance value and the timing assistance value and in accordance with the configuration parameter. Numerous other aspects are provided.

Abstract: The present disclosure presents a method and apparatus for controlling an uplink (UL) rate of one or more use equipments (UEs) served by a base station. For example, the method may include obtaining one or more measurements of a plurality of signals from a sub-set of the one or more UEs served by the base station over a period of time. Furthermore, such an example method may include comparing the measurements to one or more respective target values to generate a power activity indicator (PAI) metric and comparing the measurements to one or more respective target values to generate a power activity indicator (PAI) metric. As such, the uplink interference in heterogeneous networks may be controlled.
