Classification: CPC H | IPC H

Claim 13:
14. Circuitry for a communications device for transmitting data via a wireless communications network, the circuitry comprising:
transceiver circuitry configured to transmit signals and to receive signals on a wireless access interface of the wireless communications network; and
processing circuitry configured to control the transceiver circuitry to transmit the signals representing the data, wherein
the processing circuitry is further configured with the transceiver circuitry to:
receive a plurality of service data units including a first service data unit and a second service data unit at a Service Data Adaptation Protocol (SDAP) service access point (SAP) according to one or more quality of service (QOS) flows, each of the one or more QoS flows defining a QoS for data received from the service data units;
determine whether the first service data unit has a relative priority higher than a relative priority of the second service data unit;
map the service data units received according to the one or more QoS flows on to one or more radio bearers, each radio bearer of the one or more radio bearers defined by a packet data convergence protocol (PDCP) entity within a PDCP layer;
form the service data units into protocol data units (PDUs) for transmission via the radio bearer to which the corresponding QoS flow is mapped; and
transmit the PDUs via the corresponding radio bearer according to the mapping and in an order of PDCP sequence number.
