Issue Addressed
The normative text defining the admissions control, scheduling and aggregation behavior of the QAP and non-AP QSTA towards eDCA traffic requiring scheduled delivery is not provided in clause 9.
Steve Emeott et.al Motorola,

4. Relevant Clauses in 802.11e Draft (6.0)
January 2004
Relevant Clauses in e Draft (6.0)
In Clause , the normative behavior of the QAP when admitting an HCCA flow with a schedule is defined. However, in the counterpart Clause , the normative behavior of the QAP when admitting eDCA traffic with a schedule is unspecified.
Additionally, the normative scheduling and aggregation behavior of the QAP with an admitted HCCA traffic stream is defined in clause However, the normative behavior of both the QAP and non-AP QSTA with respect to scheduled and/or aggregated EDCA traffic is not similarly defined in clause

5. Proposed Behavior – Admission Control
January 2004
Proposed Behavior – Admission Control
The TSPEC setup signaling stays intact
A non-AP QSTA requests to establish a schedule for admitted eDCA traffic using a TSPEC element with the schedule bit set to 1 in either an ADDTS request frame or a(Re)association Request frame containing a QoS Action Element with an ADDTS request
The QAP establishes a service schedule for the eDCA traffic and conveys the schedule through the schedule element in either an ADDTS response frame, a (re)association frame, or the schedule frame

6. Proposed Behavior - Scheduling
January 2004
Proposed Behavior - Scheduling
Both the QAP and the non-AP QSTA shall honor the schedule set for admitted eDCA traffic
An eDCA scheduling function is responsible to make sure the eDCA traffic complies to the schedule and releases the eDCA frames to the eDCA channel access function at the service start time specified in the schedule
The eDCA scheduling function shall buffer the traffic arriving after the service start time until the next scheduled service start time

7. Proposed Behavior - Aggregation
January 2004
Proposed Behavior - Aggregation
The aggregation operation
Similar to the normative aggregation behavior defined in Clause for HCCA traffic under control access, the QAP may aggregate admitted eDCA traffic and generate an aggregate EDCA Service Schedule for a single non-AP QSTA
The service start time of the aggregate Service Schedule shall apply to all scheduled EDCA traffic for the QSTA
