METHODS AND APPARATUS FOR OPTIMIZING CONFIGURATION OF EXTENSION HEADERS FOR PROTOCOL DATA UNITS OF A COMMUNICATION SYSTEM

Techniques are provided for removal of a header extension to mitigate packet fragmentation. In the context of an application function, based on determining a protocol description indicating protocol data unit (PDU) set information related to extended reality data, transmission of a handling request for the PDU set that comprises at least a request for removal of a header extension related to the PDU set is caused. Additionally, based on an indication that the header extension is removable by a user plane function of a core network, transmission of at least one PDU of the PDU set comprising the header extension is caused. Corresponding method, apparatus, and computer-readable storage mediums are also provided for a core network, a user plane function, and a user equipment.
