Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a forwarding node may determine a numerology for a forwarding operation, that is associated with forwarding signals between a first wireless node and a second wireless node, based at least in part on one or more of: a numerology of a control link between the forwarding node and a control node, a delay spread of a first link with the first wireless node or a delay spread of a second link with the second wireless node, or a configuration, indicated by the control node, of the forwarding operation. The forwarding node may perform the forwarding operation based at least in part on the numerology. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a timing advance (TA) offset value for a high frequency range operating band. The UE may communicate in the high frequency range operating band, in accordance with the TA offset value. In some aspects, a UE may receive an indication of at least one of a TA offset value associated with a full-duplex communication mode of a base station or a TA offset value associated with a half-duplex communication mode of a base station. The UE may communicate, with the base station, in accordance with at least one of the TA offset value associated with the full-duplex communication mode of the base station or the TA offset value associated with the half-duplex communication mode of the base station. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a forwarding node may receive one or more synchronization signal block (SSB) communications that are to be transmitted in an SSB period. The forwarding node may store the one or more SSB communications. The forwarding node may transmit the one or more SSB communications in the SSB period. Numerous other aspects are provided.

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 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, while connected to a first cell associated with a physical cell identifier (PCI) and a first cell global identifier (CGI), a message that includes an indication to connect to a second cell, associated with the PCI and a second CGI, responsive to detecting the second CGI in a system information message associated with the PCI. The wireless node may connect to the second cell based at least in part on detecting the second CGI in the system information message associated with the PCI. Numerous other aspects are provided.

Abstract: Aspects of disclosure relate to a network node for changing a physical cell identifier (PCI). The network node transmits a first signal based on a first PCI during a first synchronization signal block (SSB) occasion, transmits a second signal based on the first PCI during a second SSB occasion, and transitions from the first PCI to a second PCI. During a transition period, the network node transmits the first signal based on the second PCI during the first SSB occasion, and continues to transmit the second signal based on the first PCI during the second SSB occasion. After an end of the transition period, the network node continues to transmit the first signal based on the second PCI during the first SSB occasion, and ceases transmission of the second signal based on the first PCI during the second SSB occasion. Other aspects and features are also claimed and described.
