Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to first central unit (CU) that corresponds to an integrated access and backhaul (IAB) donor, an indication of a first resource configuration for communications corresponding to a cell served by the network node and associated with a second CU that corresponds to a base station. The network node may receive, from the first CU, a second resource configuration comprising a distributed unit (DU) cell resource configuration for the cell. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to a first integrated access and backhaul (IAB) donor central unit (CU), an indication of a first priority level associated with a first communication resource served by a distributed unit (DU) of the network node and a second priority level associated with a second communication resource served by the DU, wherein the first priority level is higher than the second priority level. The network node may receive, from the first IAB donor CU, a first resource configuration for the first communication resource based at least in part on the indication of the first priority level. Numerous other aspects are described.

Abstract: Aspects of the present disclosure may provide an apparatus, which may include a first node that may receive an indication of a one-hop radio link control (RLC) channel packet delay budget (PDB) for an RLC channel between the first node and a second node. The PDB is across a full protocol stack or a partial protocol stack. The first node may then schedule communications with the second node based on the one-hop RLC channel PDB. In some cases, an IAB node may report a capability of its stack processing time to an IAB donor node and/or a parent IAB node (directly or indirectly).

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at an integrated access and backhaul (TAB) node. The TAB node receives a first delay parameter and a second delay parameter associated with a packet, the first delay parameter being associated with a discard determination for the packet and the second delay parameter being associated with scheduling the packet for transmission. The TAB node performs a discard decision for the packet based on the first delay parameter associated or schedules the packet for transmission to a second TAB node or a user equipment (UE) using a second delay parameter associated with the packet. A central unit (CU) of an TAB network may indicate, to an TAB node, the second delay parameter for scheduling a packet and the first delay parameter for determining whether to discard the packet.

Abstract: Aspects of the disclosure relate to beam management systems and procedures. In one example, a network node is configured to determine beam-specific gain adjustments for use with a set of wireless communication beams, wherein the wireless communication beams have one or more different beamformed spatial orientation parameters. The network node is also configured to apply the beam-specific gain adjustments to wireless communications with an access terminal. In another example, an access terminal is configured to receive beam-specific gain adjustments from a network node for use with a set of wireless communication beams, wherein the wireless communication beams have one or more different beamformed spatial orientation parameters. The access terminal is also configured to apply the beam-specific gain adjustments to wireless communications with the network node. Hierarchical beam management systems and procedures are also described. Illustrative examples exploit frequencies above 24.25 gigahertz (GHz).

Abstract: Aspects of the disclosure relate to beam configuration for RF repeaters. An RF repeater is configured to measure received power of one or more signals in the repeater for each of a plurality of beam directions. Further, the repeater determines a beam forming configuration for a fronthaul link between the repeater and at least one base station based on the measured received power of each of plurality of beam directions. The repeater may also be configured to determine beam configurations for access links between the repeater and user equipment.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiver user equipment (UE) receives, from a transmitter UE, a sidelink reference signal over a sidelink established with the transmitter UE, and transmits a sidelink timing adjust (TA) command to the transmitter UE based on the sidelink reference signal, the sidelink TA command requesting the transmitter UE to adjust a sidelink transmit time of the transmitter UE. In an aspect, a transmitter UE transmits, to a receiver UE, a sidelink reference signal over a sidelink established with the receiver UE, and receives a first sidelink TA command from the receiver UE based on the sidelink reference signal, the sidelink TA command requesting the transmitter UE to adjust a sidelink transmit time of the transmitter UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration message that includes a sounding reference signal (SRS) configuration that indicates a first set of SRS transmission parameters for the UE. The UE may receive an indication to modify the SRS configuration, wherein the indication is associated with a second set of SRS transmission parameters that is different from the first set of SRS transmission parameters. The UE may transmit one or more SRSs according to the second set of SRS transmission parameters and based at least in part on receiving the indication. Numerous other aspects are provided.
