Abstract: Methods, systems, and devices for wireless communications are described. A base station may reduce a transmission power of a scheduled downlink message relative to an expected transmission power of the scheduled downlink message in response to determining that the scheduled downlink message will cause at least a threshold level of interference with a concurrently scheduled uplink message. The base station may transmit the scheduled downlink message to a user equipment (UE) using the reduced transmission power and may transmit, to the UE an indication of a power adjustment for a downlink measurement of the scheduled downlink message. The UE may receive the indication after receiving the scheduled downlink message and may adjust the downlink measurement in accordance with the indication of the power adjustment.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access (RACH) procedure based on a selected synchronization signal block (SSB). During this RACH procedure, a base station may transmit physical downlink control channel (PDCCH) messages for UE RACH message handling. To receive PDCCH signaling for RACH Messages 2, 3, or 4 (Msg 2/3/4), the UE may identify a set of time resources used by the base station for transmitting SSBs that are not quasi-co-located (QCL) with the selected SSB. The UE may identify a Msg 2/3/4 search space that does not overlap with this identified set of resources, and may monitor this identified search space. The search space may correspond to a modified remaining minimum system information (RMSI) search space indicated by the base station, or a valid RMSI search space not indicated by the base station.

Abstract: A node may identify a node configuration including one or more surface phase configurations associated with the node. In one configuration, the node may receive, from the base station, an indication of the node configuration. In another configuration, the node may select, at a controller associated with the node, the node configuration. The one or more surface phase configurations may be based on a wavelength corresponding to a center of a BWP associated with the one or more wireless signals or a wavelength corresponding to a center of a resource allocation associated with the one or more wireless signals. The node may forward, from a base station to a UE, or from the UE to the base station, one or more wireless signals. The forwarded one or more wireless signals may be associated with a beam squint less than a first threshold.

Abstract: Apparatus, methods, and computer-readable media for facilitating a programmable smart repeater with in-band control are disclosed herein. An example method for wireless communication at a repeater includes establishing a control link with a control node and receiving, via the control link, a configuration of one or more parameters of the repeater to forward communication between a first wireless device and a second wireless device. The example method also includes transitioning an MT component of the repeater to a power saving mode for at least a period of time after receiving the configuration and forwarding the communication between the first wireless device and the second wireless device based on the one or more parameters in the configuration. The disclosed techniques may enable reduction in control signaling between the control node and the repeater to provide power savings for the MT of the repeater and lower signal overhead for the control node.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on synchronization signal blocks (SSB) in a network (e.g., an Integrated Access and Backhaul (IAB) network. In some cases, a node determines resources used for periodic SSB transmissions by at least one parent node of the network, uses the determined resources to perform SSB-based interference measurements, and communicates with at least one of the parent node, a central unit (CU), or another node of the network based on the SSB-based interference measurements.

Abstract: A method of handover at a user equipment (UE) is provided comprising receiving, from a first network entity (NE), a configuration for conditional handover associated with a second NE. The configuration includes at least one condition. An indication is received by the UE from the first NE to execute the conditional handover. Handover is initiated from the first NE to the second NE subject to the condition being satisfied. The condition may be that the indication is received or it may be a channel condition or both. At an NE, configurations for conditional handover are sent to multiple UEs, each configuration associated with a target NE and each including at least one condition, and an indication is sent to at least one UE to execute conditional handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a parameter switch configuration that indicates at least one parameter switching pattern associated with two or more values of a configuration parameter, the parameter switching pattern corresponding to a periodic uplink communication and a periodic downlink communication. The UE may communicate, based at least in part on the parameter switching pattern, with at least one wireless communication device based at least in part on the periodic uplink communication and the periodic downlink communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may support communications between various network nodes via repeaters to extend coverage to areas that may be otherwise uncovered. A repeater may forward a signal using a circular polarization type. A receiving network node may receive a signal transmitted with a circular polarization type using a linear antenna configuration without a risk of the signal being orthogonal to the linear antenna configuration, and therefore not received by the receiving network node. A repeater may report, to a control entity, a capability of the repeater to forward signals using a set of one or more polarization types (e.g., including at least one circular polarization type), and in response the repeater may receive scheduling information indicating for the repeater to forward a signal in a given communication resource using a particular polarization type (e.g., a particular circular polarization type).

Abstract: Methods, systems, and devices for wireless communications are described. A central unit (CU) function of a base station may identify a first set of user equipment (UE) to communicate via sidelink communications with a distributed unit associated with the central unit. The CU function may determine, based at least in part on the distributed unit being an integrated access and backhaul provider to the first set of UE, a first configuration for the distributed unit to use for sidelink communications with the first set of UE, the first configuration different than a second configuration for one or more nodes associated with the base station to use for sidelink communications with a second set of UE in communication with the base station. The CU function may provide an indication of the first configuration to the distributed unit.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a first network entity may transmit a request for resources (e.g., periodic, aperiodic, or semi-persistent resources) to monitor for reference signals from a second network entity, and the first network entity may perform CLI measurements on the reference signals received on the resources from the second network entity. The first network entity or the second network entity may be a mobile network entity. The CLI measurements may be used to schedule communications at the first network entity or the second network entity. In another aspect, a first network entity may receive an indication of aperiodic resources to monitor for reference signals from a second network entity, and the first network entity may perform cross link interference (CLI) measurements on the reference signals received on the aperiodic resources from the second network entity.
