Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a first integrated access and backhaul (IAB) donor central unit (CU), information indicating a first resource configuration used by an IAB node that has a first connection with a first parent IAB node that is a child of the first IAB donor CU. The first network node may transmit, to a second parent IAB node that is a child of the first network node, the information. Numerous other aspects are described.

Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.

Abstract: Aspects of the present disclosure provide mechanisms for transmitting discovery signals to enable discovery of a cell. Synchronization signal blocks (SSBs) carrying the cell identifier of the cell may then be transmitted either on-demand or with a higher periodicity than discovery signals. The discovery signals and SSBs may be transmitted within a same bandwidth part and on at least overlapping sets of frequency resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central network node may transmit, to a distributed network node, a configuration of a statistic associated with a traffic instance for communicating with a user equipment (UE). The central network node may receive an indication associated with the distributed network node communicating with the UE using the traffic instance and in accordance with the statistic. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node in an integrated access and backhaul (IAB) network may transmit, to an IAB node having a mobile termination function (IAB-MT) and a distributed unit (IAB-DU), signaling indicating a set of restricted IAB-DU beams and associating the set of restricted IAB-DU beams with one or more IAB-MT beams, the set of restricted IAB-DU beams determined based on measurements related to interference caused by the IAB-DU and the IAB-MT performing a simultaneous operation in one or more simultaneous multiplexing modes. Additionally or alternatively, the parent node may perform scheduling for the IAB-MT based on signaling received from the IAB node that indicates beam-specific parameters related to a multiplexing capability for a beam pair that includes an IAB-MT beam and an IAB-DU beam associated with the IAB-MT beam. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may receive, from a distributed unit (DU), a first DU configuration. The CU may transmit to the DU, a second DU configuration to change a DU configuration from the first DU configuration to the second DU configuration, the first DU configuration being different from the second DU configuration. The DU may override the first DU configuration to communicate in accordance with the second DU configuration. Numerous other aspects are provided.

Abstract: In some aspects, a node may configure whether a set of soft time resources is to be conditionally released or unconditionally released. The set of soft time resources may be configurable in a schedulable state or a non-schedulable state. The set of soft time resources may be schedulable subject to at most a directionality constraint when unconditionally released and, when conditionally released, being schedulable subject to: the directionality constraint and one or more conditions other than the directionality constraint if the set of soft resources is configured subject to the directionality constraint, or at least one of the directionality constraint or the one or more conditions other than the directionality constraint if the set of soft resources is not configured subject to the directionality constraint. The node may transmit a configuration that indicates whether the set of soft time resources is conditionally released or unconditionally released in the schedulable state.
