Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may receive one or more cross-link interference (CLI) measurement reports that are based at least in part on one or more CLI measurements performed by one or more downstream nodes. The CU may transmit, and a distributed unit (DU) may receive, CLI measurement information based at least in part on the one or more CLI measurement reports. In some aspects, the DU may perform one or more CLI mitigation actions based at least in part on the CLI measurement information received from the CU. Numerous other aspects are provided.

Abstract: A method for wireless communication at a user equipment (UE) includes receiving, from a base station, multicast data via a multicast channel. The method also includes transmitting, to the base station, multicast feedback based on receiving the multicast data. In some examples, the multicast feedback is associated with a group of UEs including the UE. The method further includes receiving, from the base station, a re-transmission of the multicast data on the multicast channel or a unicast channel based on one or more of a number of UEs served by the base station, a number of UEs from the group of UEs providing the multicast feedback, or a radio channel condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may transmit, to a second wireless node, a cross-link interference (CLI) management configuration message including information identifying a time division duplexing configuration of a mobile terminal of a third wireless node; and communicate with one or more wireless nodes in accordance with the time division duplexing configuration of the mobile terminal based at least in part on transmitting the CLI management configuration message to the second wireless node. Numerous other aspects are provided.

Abstract: A UE may be configured to determine a size of the TB for transmission to a base station based on signaling received from the base station for configuration of at least one of a scale factor or a slot aggregation factor associated with size of the TB. The UE may be further configured to transmit, to the base station, information on the TB in at least one slot, the TB being of the determined size. The base station may be configured to transmit, to the UE, the signaling for configuration of at least one of a scale factor or a slot aggregation factor associated with a size of the TB to be used by the UE for transmission. The base station may be further configured to receive, from the UE, information on at least one TB having a size that is based on at least one of the scale factor or the slot aggregation factor.

Abstract: Aspects relate to measurement and event reporting from a distributed unit (DU) of a disaggregated base station to a central unit (CU) of the disaggregated base station. The CU can configure the DU with a measurement configuration associated with at least one value to be obtained by the DU and a reporting configuration for reporting the at least one value to the CU. The measurement reports can be sent by DU periodically or the measurement reports can be event-triggered based on the reporting configuration. In addition, the measurement reports can be UE-specific or DU/cell-specific. The measurement reports may include random access channel (RACH) reports, uplink measurement reports, radio link protocol (RLC) reports, medium access control (MAC) protocol reports, and other types of measurement or event-based reports.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station (BS) may receive, from a user equipment (UE), an overheating assistance information communication that indicates a maximum quantity of component carriers, combined between the first BS and a second BS, for the UE. The first BS may transmit, to the second BS, a request to reduce a quantity of component carriers of the second BS configured for the UE such that a total quantity of component carriers, between the first BS and the second BS, configured for the UE satisfies the maximum quantity of component carriers. 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 a configuration for a multicast/broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode; enter an idle state or an inactive state after the MRB has been configured; and maintain the MRB while the UE is in the idle state or the inactive state subject to one or more limitations associated with maintaining the MRB in the idle state or the inactive state. Numerous other aspects are provided.

Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection. In an aspect, either the slave UE or the master UE may perform encryption and decryption of control plane signaling using the slave UE's security credentials.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to performing a handover on a per-data radio bearer (DRB) basis. In some examples, the disclosure is directed to indicating, to a source network entity, a make-before-break (MBB) handover capability of the UE, the MBB handover capability supporting MBB handovers for one or more DRBs identified by the source network entity. In some examples, the disclosure describes receiving, from the source network entity, configuration information for a handover from the source network entity to a target network entity, the configuration information identifying the one or more DRBs supported for the MBB handover.
