Extended reality in wireless communication

A user equipment (UE) device for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE device to:
• generate, by a first protocol layer, one or more protocol data units (PDU), the one or more PDU comprising one or more headers and the one or more headers comprising one or more fields indicating information related to a protocol data unit (PDU) set associated with the one or more PDU;
• transmit, via a second protocol layer, the one or more PDU to an extended reality (XR) device;
• and
• receive, from the XR device, data transmission.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive, by a first protocol layer, one or more service data units (SDU) from a second protocol layer;
• implement one or more headers for the one or more SDU, the one or more headers comprising one or more fields indicating information related to a protocol data unit (PDU) set associated with the one or more SDU;
• generate, based at least in part on the one or more SDU, a PDU comprising an SDU and a corresponding header;
• and
• submit the PDU to a third protocol layer.
