User equipment and methods for communication between the user equipment and a network entity using a QUIC protocol

A method for communication with a user equipment (UE), comprising:

• receiving, by a first network entity, a session establishment request or a session modification request from a second network entity indicating information of a quality of service (QOS) flow of a multi-access (MA) protocol data unit (PDU) session;
• receiving, by the first network entity, a QUIC packet from the UE via the QoS flow of the MA PDU session;
• and
• determining, by the first network entity, association between the QUIC connection and the QoS flow of the MA PDU session associated with the QUIC connection according to the QUIC packet.

A user equipment (UE), comprising:

• a radio frequency (RF) transceiver configured to receive data from a network entity and transmit data to the network entity;
• and
• a processor coupled to the RF transceiver and configured to:
• control the RF transceiver to initiate establishment of a QUIC (Quick User Datagram Protocol Internet Connection) connection for each quality of service (QOS) flow of a multi-access (MA) protocol data unit (PDU) session established between the network entity and the UE;
• control the RF transceiver to send a QUIC packet to the network entity via a QoS flow of the MA PDU session associated with the QUIC connection during establishment of the QUIC connection;
• and
• control the RF transceiver to send all uplink traffic of the QUIC connection to the QOS flow associated with the QUIC connection after the establishment of the QUIC connection is completed.
