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: Methods, systems, and devices for wireless communications are described that provide for cooperative full-duplex techniques for sidelink communications. A first device that supports full-duplex communications may transmit a first message to a second device while concurrently receiving a second message from a third device. The first device may determine a set of parameters that indicate a presence of one or more objects that cause interference at the first device based on communicating with the second and third devices. The set of parameters may include location information, directional beam information, main beam information, and null interference beam information, or velocity information, or any combination thereof. The first device may broadcast an indication of the set of parameters to other devices. In some examples, a device that receives the set of parameters may determine communications parameters for communication with other devices that accounts for the indicated objects.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may selectively transmit, to a network entity, a request for a dedicated system information block type 1 (SIB1) for a target cell based at least in part a determination of whether an SIB1 request criterion is satisfied for an idle state cell reselection from a source cell to the target cell. The UE may receive, from the network entity, an indication of one or more target cell SIB1 parameters included in the dedicated SIB1 for the target cell, based at least in part on transmitting the request for the dedicated SIB1 for the target cell. Numerous other aspects are provided.

Abstract: A network node may output downlink communication for a UE. The UE may receive the downlink communication from the network node. The UE may transmit, to the network node, a request for a first downlink transmission power adjustment for the downlink communication from the network node to the UE. The network node may obtain the request from the UE for the first downlink transmission power adjustment for the downlink communication from the network node to the first UE.

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: 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: Disclosed is a method for wireless communication for determining the position of a wireless node. The method comprises receiving a set of reference signals from a set of at least four positioning devices, wherein the positioning devices are not arranged in a single plane. A signal propagation delay of each one of the set of reference signals is determined and a position of each one of the set of positioning devices is obtained. A convex localization problem is solved for the wireless node based at least in part on the determined signal propagation delay of each one of the set of reference signals and the position of each one of the set of positioning devices. The position of the wireless node is determined based at least in part on solving of the convex localization problem.
