Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device or integrated access and backhaul (IAB) node. In one aspect, the wireless device may determine a frequency synchronization accuracy for the wireless device. The wireless device may also transmit an indication of the determined frequency synchronization accuracy for the wireless device. Additionally, the wireless device may determine an absolute frequency based on a combination of measurements from at least one synchronization source and a frequency of the wireless device, where the frequency synchronization accuracy is based on the absolute frequency.

Abstract: Aspects relate to a base station configured to transmit a message to a sidelink (SL)-repeater, configuring the SL-repeater to transmit sidelink synchronization signal blocks (S-SSBs) including S-SSB index numbers, receive a SL-node identification and a preferred S-SSB index number, and transmit the SL-node identification and the preferred S-SSB index number to the SL-repeater. The base station may be configured to transmit a first message configuring a SL-repeater to broadcast a sidelink discovery message, receive a sidelink discovery report from the SL-repeater identifying discovered SL-node(s), and transmit a second message activating the SL-repeater for sidelink communication with the SL-node(s). Another aspect relates to a SL-repeater configured to: transmit a sidelink discovery message, receive first response(s) from respectively responding SL-node(s), and transmit a report to a base station identifying a change in membership between a first list of the respectively responding SL-node(s) and a second list of previously responding SL-nodes.

Abstract: Beam-related paging assistance information can be exchanged between a core network, radio access networks, and user equipment. Beam-related paging assistance information can enable more efficient paging operations at a base station. A centralized unit (CU) of a base station can exchange beam-related paging assistance information with a distributed unit (DU) of the base station to facilitate paging operations using the beam-related paging assistance information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may apply a crest factor reduction (CFR) to an input signal to generate an output signal, the applying the CFR to the input signal including applying a shaping filter that distributes a first portion of CFR noise within a transmission frequency band of the output signal and a second portion of the CFR noise in at least one air interface resource that is outside of the transmission frequency band of the output signal. The network node may transmit the output signal. Numerous other aspects are described.

Abstract: Aspects described herein relate to establishing a control connection with at least a first node and a second node for receiving control information for providing a repeater function between two or more wireless nodes. Control information can be communicated over the control connection from one or more of at least the first node or the second node. The repeater can provide, based on the control information, the repeater function between the two or more wireless nodes. Other aspects relate to establishing a control connection with a first node for receiving control information for providing a repeater function for one or more upstream nodes, receiving control information over the control connection, determining a conflict in receiving the control information or a conflict within the control information for two or more upstream nodes, and providing, based on the control information and conflict, the repeater function for the one or more upstream nodes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU. The first node may transmit or receive a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication. Numerous other aspects are described.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A radio access network (RAN) entity (e.g., a scheduling entity, such as a base station or parent integrated access backhaul (IAB) node, or a centralized network node, such as an IAB donor node central unit) may provide support to a scheduled entity (e.g., a user equipment (UE) or child IAB node) to operate in an autonomous time adjustment (ATA) mode to autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. The RAN entity may generate ATA mode information related to the ATA mode for the scheduled entity and transit the ATA mode information to the scheduled entity.

Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

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.
