A wireless transmit / receive unit (WTRU) may transmit a request message to establish or modify a protocol data unit (PDU) session with a network. In an example, the request message may indicate that the PDU session is an alternative PDU session. Also, the WTRU may receive, from the network, indication information indicating that the PDU session is the alternative PDU session. Further, the WTRU may determine, based on the received indication information, whether the PDU session is in a drop state. Moreover, the WTRU may transmit, based on a determination that the PDU session is no longer in the drop state, uplink data associated with the PDU session. In a further example, the determination that the PDU session is no longer in the drop state may be based on indication information in an attention (AT) command. In addition, the indication information in the AT command may be received from an application.
