Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may receive, from a second WCD, transmission configuration indicator (TCI) state information that defines a set of TCI state configurations for a full duplex operation, wherein TCI state configurations of the set of TCI state configurations are associated with respective receive beams and respective transmit beams. The WCD may transmit, to the second WCD, an indication of one or more candidate TCI states, associated with the set of TCI state configurations, for selection by the second WCD for communications using the full duplex operation. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more transmit receive point (TRP) pairing indications, wherein the one or more TRP pairing indications identify one or more TRPs that have a capability to be paired with one or more neighbor TRPs in a full-duplex communication mode or one or more TRPs that have a capability to be paired with one or more neighbor TRPs in a simultaneous half-duplex multi-TRP (mTRP) communication mode. The UE may transmit, to a base station, a report indicating at least one candidate TRP to be paired in the full-duplex communication mode or the simultaneous half-duplex mTRP communication mode based at least in part on the one or more TRP pairing indications. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, while communicating with a serving transmit receive point (TRP) in a half-duplex communication mode, one or more synchronization signal block (SSB) beams associated with one or more neighbor TRPs. The UE may transmit, to a base station, a mobility report indicating at least one candidate TRP based at least in part on determining that an SSB beam transmitted by the at least one candidate TRP satisfies criteria to be paired in a full-duplex communication mode or a simultaneous half-duplex multi-TRP (mTRP) communication mode. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving, by a mobile termination (MT) function of an integrated access and backhaul (IAB) node, a first indication to migrate from a first IAB donor node associated with a first cell group and a first central unit (CU) to a second IAB donor node associated with a second cell group and a second CU, performing, by the IAB node and based at least in part on receiving the first indication, a first random access procedure to connect to the second cell group associated with the second IAB donor node, establishing, by the IAB node in addition to a first distributed unit (DU) function of the IAB node that serves a third cell group and based on performing the first random access procedure, a second DU function that serves a fourth cell group.

Abstract: In an aspect, a network device (e.g., BS, core network component, etc.) determines a self-interference measurement (SIM) configuration associated with null-forming at a wireless device (e.g., UE or BS), the null-forming associated with steering at least one receive beam of the wireless device and/or at least one transmit beam of the wireless device away from one or more external sources of self-interference. The network device transmits the SIM configuration to the wireless device. The wireless device performs at least one null-forming procedure in accordance with the SIM configuration.

Abstract: Wireless communications systems and methods related to sharing channel occupancy time (COT) for a channel in an unlicensed 5G spectrum in an integrated access backhaul (IAB) network are provided. In some aspects, an IAB node of the IAB network may perform a channel access procedure to acquire the COT and share the COT with a parent IAB node and/or a child IAB node for the parent IAB node and/or child IAB node for the parent IAB node and/or child IAB node to share, or use the COT for communication, with a third IAB node different from the COT-initiating IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node may receive a message, from a serving or neighboring cell, that includes an indication of an intended time division duplex (TDD) configuration for the serving or neighboring cell. The indication may include downlink and uplink indicators for at least one slot used within the intended TDD configuration. Accordingly, the child node may determine a symbol to use within a TDD configuration for the child node, based at least in part on receiving the message. Numerous other aspects are provided.

Abstract: A method of wireless communication is presented. The method includes receiving, at a user equipment (UE) from a base station, a measurement configuration comprising quasi-co-location (QCL) information for a serving reception beam. The method also includes measuring cross-link interference experienced on the serving reception beam. The method further includes transmitting the QCL information for the serving reception beam and a corresponding sounding reference signal-reference signal received power (SRS-RSRP) or cross-link information-received signal strength indicator (CLI-RSSI) to the base station.
