A method includes receiving, by a user device having a first connection to a network via a first access node, a first message including at least one of an identifier of a second access node or timing information associated with an availability of the second access node, receiving, from a third access node, an identifier of the third access node, sending, to the third access node, a second message indicating a request for a resume of the first connection via the third access node, and receiving from the third access node, a third message including assistance information indicating at least one of: whether to resume the first connection, to wait for the second access node to resume the first connection, to release the first connection, or to establish a second connection via the third access node.
Enhanced event-based beam reporting is provided. A method for enhanced event-based beam reporting may include performing a first measurement related to one or more reference signals of one or more cells based on a received configuration. The received configuration may include one or more reporting conditions for measurement reporting. The method may also include storing information related to the first measurement and performing the measurement reporting by transmitting, to a network entity, a first report based on satisfying the one or more reporting conditions of the configuration. The first report may be based, at least in part, on the information related to the first measurement.
Systems, methods, apparatuses, and computer program products for reporting AI/ML- based positioning output with a tag information on the input of an AI/ML model. One method may include receiving, by a UE, positioning information comprising at least one DL PRS; performing, by the UE, at least one measurement of the at least one DL PRS; and transmitting, based at least partially on the at least one measurement, at least one of positioning inference information or tag information associated with at least one of an AI model input or an AI model output.

Embodiments of the present disclosure relate to transmitting or receiving scheduling requests (SRs) for logical channels (LCHs). In an aspect, a terminal device receives at least one SR configuration for a LCH. An SR configuration among the at least one SR configuration is associated with at least one LCH event. Based on detecting, for the LCH, an LCH event among the at least one LCH event, the terminal device transmits the SR for the LCH based on the SR configuration associated with the LCH event detected. This way, scheduling can be required reliably for delay sensitive service.
