Quality of service of extended reality media over a wireless communication network

A user equipment (UE) 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 to:
• transmit, via a data radio bearer, Protocol Data Units (PDUs) of a first PDU set using a first quality of service (QoS) mapping rule;
• receive downlink packets for the data radio bearer containing header information including at least one QoS parameter indicating a second QoS mapping rule;
• apply the first QoS mapping rule to uplink transmissions on the data radio bearer until the transmission of the last PDU of the first PDU set;
• and
• transmit PDUs of a second PDU set using the second QoS mapping rule.

A processor for wireless communication, comprising:

• at least one controller coupled with the at least one memory and configured to cause the processor to:
• transmit, via a data radio bearer, Protocol Data Units (PDUs) of a first PDU set using a first quality of service (QoS) mapping rule;
• receive downlink packets for the data radio bearer containing header information including at least one QoS parameter indicating a second QoS mapping rule;
• apply the first QoS mapping rule to uplink transmissions on the data radio bearer until the transmission of the last PDU of the first PDU set;
• and
• transmit PDUs of a second PDU set using the second QoS mapping rule.
