Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a channel measurement (CM) process indicating at least one channel measurement resource (CMR) associated with quasi co-location (QCL) information, wherein the QCL information corresponds to a transmit (Tx) beam of the base station associated with a receive (Rx) beam of the UE; receive a configuration for an interference measurement (IM) process indicating at least one interference measurement resource (IMR) associated with a UE beam pair comprising the Rx beam of the UE and a Tx beam of the UE; perform a self-interference measurement (SIM), wherein the SIM procedure is based at least in part on the CM process and the IM process; and transmit, to the base station, a measurement report based at least in part on the SIM procedure. Numerous other aspects are provided.

Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

Abstract: Aspects relate to an integrated access backhaul (IAB)-Distributed Unit (DU) resource configuration framework for paired (e.g., frequency division duplex (FDD)) spectrum. Two DU resource configurations per cell may be supported for paired spectrum, including one for a first spectrum band (e.g., a downlink frequency band) and another for a second spectrum band (e.g., an uplink frequency band) of the paired spectrum. Each DU resource configuration may include a respective symbol pattern of symbol types (e.g., downlink (DL), uplink (UL), flexible) for a plurality of slots, as well as a corresponding availability attribute for each symbol type (e.g., hard, soft, or not available). A DU of an IAB node in an IAB network may receive the two DU resource configurations for the paired spectrum from a central unit (CU) of an IAB donor node in the IAB network.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater that relays communications between communication devices. The repeater determines one or more power configuration parameters associated with the repeater and transmits the one or more power configuration parameters to a controlling node, such as a base station or other entity. The repeater receives, from the controlling node, gain configuration information determined based on the one or more power configuration parameters. A repeater may receive a communication, determine a gain value based on the gain configuration information, and apply the gain value to the received communication to create a gain adjusted communication for transmission to another device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless serving node may determine mobility history information associated with the wireless serving node, wherein the mobility history information is associated with a relative mobility between the wireless serving node and one or more reported cells; and transmit, to a child node of the wireless serving node, the mobility history information associated with the wireless serving node. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a system information block (SIB) including configuration information associated with configuring operation of a plurality of repeaters, wherein repeaters in the plurality of repeaters are configured to receive signals from first wireless communication devices and forward the signals to second wireless communication devices. The wireless communication device may communicate in a set of resources based at least in part on the configuration information included in the SIB. Numerous other aspects are provided.

Abstract: Aspects presented herein may enable an IAB node to modify a resource allocation or change one or more parameters related to the resource allocation when the IAB node detects that the resource allocation overlaps with guard symbols or another resource allocation. In one aspect, an IAB node determines that a first channel allocation will be punctured based on an overlap of the first channel allocation with at least one of a guard symbol or a second channel allocation. The IAB node uses, for the first channel allocation or the second channel allocation, one or more of a modified parameter or a modified grant in response to determining that the first channel allocation will be punctured.

Abstract: An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.
