Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a base station may configure a user equipment (UE) for random access (RACH) message transmission in dedicated RACH resources during, for example, a handover process. The contention-free random access (CFRA) resources may allow the UE to transmit RACH messages at a higher transmission power than contention-based random access (CBRA) resources. The base station may indicate, to the UE, RACH transmission parameters for CFRA that are different than parameters for CBRA. These parameters may include configuration information, frequency division multiplexing information, RACH retransmission parameters, target received power, response window length, etc. The UE may use the indicated RACH transmission parameters to transmit a RACH message to the base station. The base station may respond with a RACH response message, and the base station and UE may synchronize upon completion of the RACH procedure.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media for beam switching by a repeater node that forwards communications from one of a first node or a second node to the other of the first node or the second node. For example, after a change of position by the second node, the first node may provide the repeater node an instruction to perform a beam change operation to communicate with the second node. In some aspects, performing the beam change operation by the repeater node may improve reliability of wireless communications, such as by focusing signal energy in a particular direction. Further, a beam change delay time interval or a scheduling of the beam change delay time interval may be selected based on scheduling associated with other nodes, which may reduce a number of messages sent to the repeater node (such as by reducing instructions to change beam directions).

Abstract: Methods, systems, and devices for wireless communications are described. A child node may communicate in an integrated access and backhaul (IAB) communications system with a parent node and the parent node may transmit system information to the child node that may indicate one or more random access channel (RACH) procedure configurations such as a user equipment (UE)-specific RACH procedure configuration and a wireless backhaul-specific (e.g., IAB-specific) RACH procedure configuration. The child node may be configured to utilize the UE-specific RACH procedure configuration or the IAB-specific RACH procedure configuration such as if the child node meets one or more conditions or upon receiving an indication from the parent node. The child node may determine to use the UE-specific RACH procedure configuration for communicating with the parent node and may perform a RACH procedure with the parent node in accordance with the UE-specific RACH procedure configuration.

Abstract: The present disclosure generally relates to wireless communication. A user equipment may receive information indicating whether a reference signal is associated with a full-duplex operation; receive the reference signal; and transmit feedback based at least in part on the reference signal and the information indicating whether the reference signal is associated with the full duplex operation.

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: Methods, systems, and devices for wireless communication are described. In a wireless communication system, a first wireless node may transmit a configuration message indicating one or more spatial configurations for communicating with a second wireless node. A spatial configuration may include one or more different sets of spatial parameters for half-duplex communications and full-duplex communications between the wireless nodes. In some examples, the first wireless node may select a first set of spatial parameters for half-duplex communications or a second set of spatial parameters for full-duplex communications based on an explicit indication or a resource configuration. The wireless nodes may perform half- or full-duplex communications using the first or second set of spatial parameters, respectively, in accordance with the configuration message.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit transmit power information for a distributed unit (DU) to a central unit (CU). The first node may receive, from the CU in connection with transmitting the transmit power information, an indication of a transmit power parameter to use for transmitting a communication. The first node may transmit the communication with a transmit power that is based at least in part on the transmit power parameter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may be scheduled by a base station for full-duplex sidelink transmissions. A first UE may receive, from a base station, a first sidelink grant indicating a first set of resources and a second set of resources. The first set of resources may at least partially overlap in time with the second set of resources. Upon receiving the first sidelink, the first UE may transmit, to a second wireless device, a second sidelink grant indicating the second set of resources. The first UE may transmit a first data message to the second UE over the first set of resources and receive a second data message from the second device over the second set of resources.
