Abstract: The present disclosure relates to a communication apparatus and method for supporting a forward error correction scheme in a communication system. To this end, by means of a generation mode among a plurality of generation modes (ssbg_mode #0, #1, #2), a source symbol block having a plurality of source symbols is generated by using a source packet block having a plurality of source packets, and a repair symbol block for the generated source symbol block is generated by means of a forward error correction (FEC) scheme among a plurality of FEC schemes (FEC payload ID mode 0, FEC payload ID mode 1). A first FEC scheme (FEC payload ID mode 1) is applied to generate the repair symbol block, and in response to an occurrence of a discontinuity in packet sequence numbers, a repair packet may be generated to include length repair data and a repair FEC payload identifier (ID).

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method of a user equipment (UE) performing a quality of experience (QoE) reporting operation for extended reality (XR) media services is disclosed. The method comprises receiving configuration information for a QoE reporting operation, determining whether an event for the QoE reporting operation is triggered based on the configuration information, generating a frame rate QoE metric comprising pose information of the UE, generating a round-trip time (RTT) QoE metric comprising a tethered delay between at least one tethered device and the UE, generating a codec QoE metric comprising 3D media codec type for 3D media, in response to the event being triggered, generating a QoE report comprising at least one of the frame rate QoE metric, the RTT QoE metric, or the codec QoE metric, and transmitting the generated QoE report.
