A wireless communication device may receive a data packet having a header that includes a first plurality of fields. The wireless communication device may also schedule transmission of the data packet based on QoS parameters associated with the first plurality of fields. The transmission of the data packet may be scheduled based on QoS parameters associated with the first plurality of fields when the first plurality of fields match a second plurality of fields. Other features are also described. ## Claims ### Claim 1 A method of wireless communication, comprising: receiving a data packet having a header that includes a first plurality of fields; and scheduling transmission of the data packet based on quality-of-service (QoS) parameters associated with the first plurality of fields when the first plurality of fields match a second plurality of fields. ### Claim 2 (depends on 1) The method of claim 1, wherein the second plurality of fields comprises separate fields to indicate a Source Internet Protocol (IP), a Destination IP, a Source Port, a Destination Port, a Protocol Identification (ID), and a Connection ID. ### Claim 3 (depends on 2) The method of claim 2, wherein the field that indicates the Connection ID includes at least one of a field that indicates a Source Connection ID and/or a field that indicates a Destination Connection ID. ### Claim 4 (depends on 3) The method of claim 3, further comprising: receiving another data packet having another header that includes a third plurality of fields;
