Claim 0:
1. A method of transmitting data by a communications device, the method comprising:
receiving 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;
determining whether the first service data unit has a relative priority higher than a relative priority of the second service data unit;
mapping 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;
forming the service data units into protocol data units (PDUs) for transmission via the radio bearer to which the corresponding QoS flow is mapped; and
transmitting the PDUs via the corresponding radio bearer according to the mapping and in an order of PDCP sequence number.
