Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for measuring, filtering, and reporting cross-link interference (CLI) in cases where not all aggressor user equipments (UEs) are transmitting signals that can be measured by a victim UE. A UE may obtain a set of CLI measurements by performing CLI measurements during a set of CLI measurement occasions. The UE may determine a first subset of the set of CLI measurements that satisfy a CLI measurement threshold and a second subset of the set of CLI measurements that do not satisfy the CLI measurement threshold. The UE may apply a filter to the first subset of the set of CLI measurements, and suppress the filter for the second subset of the set of CLI measurements, to obtain a filtered CLI measurement value. The UE may transmit the filtered CLI measurement value to a base station.

Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a user equipment (UE) may generate an indication of a first doppler shift associated with the wireless communication device moving with reference to a first target base station (BS), obtain, from the serving BS, a handover command for conditional handover (CHO) (with the handover command including a first trigger for handover to the first target BS), and synchronize with the first target BS during CHO after the first trigger is met, wherein the first trigger is associated with the first doppler shift. In another aspect, a serving BS generates the handover command for CHO and provides the handover command to the UE. The UE is to synchronize with the first target BS during CHO after the first trigger associated with a first doppler shift is met.

Abstract: Methods, systems, and devices for on-demand multicast control channel (MCCH) messages are described. A user equipment (UE) may receive, from a base station, system information indicating an MCCH message configuration. Based on receiving the MCCH message configuration, the UE may transmit a request for an MCCH message. For example, the UE may transmit the request for the MCCH message by a random access preamble or a radio resource control (RRC) message. After transmitting the request, the UE may receive the MCCH message in accordance with the MCCH message configuration. That is, the base station may receive the request and transmit the MCCH message in response to the request. The MCCH message may indicate a multicast service radio bearer (MRB) configuration for receiving multicast traffic. Thus, the UE may receive multicast traffic from the base station in accordance with the MRB configuration.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support AI model-based enhancements for RRC IDLE and INACTIVE state operations. In a first aspect, a method of wireless communication includes receiving, by a wireless communication device, artificial intelligence (AI) model configuration information for IDLE/INACTIVE state procedures; retrieving, by the wireless communication device, an AI model for IDLE/INACTIVE state procedures based on the AI model configuration information; and performing, by the wireless communication device, one or more IDLE/INACTIVE state procedures based on the AI model. Other aspects and features are also claimed and described.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity transmits, to a user equipment (UE), at least one file, the at least one file comprising a group of data packets, wherein each data packet of the group of data packets of the at least one file is associated with a file identifier of the at least one file, transmits, to the UE, after transmitting the last data packet of the group of data packets of the at least one file, a request for the UE to report a reception status of the at least one file, transmits, to the UE, one or more repair bits for the at least one file, receives an acknowledgment from the UE, and ceases transmission of the one or more repair bits upon reception of the acknowledgment from the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a master node associated with a primary cell, a configuration for a conditional procedure for adding or changing a primary secondary cell (PSCell) associated with a secondary node. The UE may also receive, from the master node, a configuration for a handover procedure for the primary cell. The UE may transmit a report that includes information related to the conditional PSCell procedure, information related to the primary secondary cell, or both, based on a triggering order between the conditional PSCell procedure and the handover procedure.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.
