Abstract: Methods and apparatus for classifying a traffic packet service of a traffic flow to a client device, a state and/or video resolution of a streaming video player in a client device. The apparatus includes a memory, and a communication interface configured to obtain TCP/IP or UDP/IP headers of packets to a client device, at least one processor operably connected to the memory, the at least one processor configured to detect a start of a traffic flow, and buffer a first number of packets for the traffic flow, extract features from UDP/IP or TCP/IP headers of a second number of packets belonging to the detected traffic flow, and obtain a flow service classifier for classifying a service type of the traffic flow, and classify the service type of the traffic flow by applying the extracted features to the flow service classifier.

Abstract: A method of a user equipment (UE) for control resource set (CORESET) configuration in a wireless communication system is provided. The method comprises receiving, from a base station (BS), system information, determining whether the system information includes a random access channel (RACH) CORESET configuration, determining a CORSET to use for transmitting data based on whether the RACH CORESET configuration is included in the system information, and receiving, from the BS, the data based on the determined CORESET over an RACH.

Abstract: A method of a user equipment (UE) for beam management in a wireless communication system is provided. The method comprises receiving, from a base station (BS), a radio resource control (RRC) signaling and a medium access control channel element (MAC CE) signaling including a beam indicator over a downlink channel for the beam management, identifying the beam indicator based on the RRC signaling and the MAC CE signaling, and determining the beam indicator for a physical downlink control channel (PDCCH), a common physical downlink shared channel (PDSCH), and a fallback unicast PDSCH.
