In addition to passing the normal background checks, the following points are manually
verified:
1. The DUT/INTD should stop sending ctrl/data in the superframe where the
tiebreaker is lost.
In addition - the DUT/INTD should perform one of the following:
(a) Abandon the reservation
(b) Change the status of its reservation to zero.
• If the DUT loses the tie-breaker in the first conflicting superframe (with tester's
tiebreaker bit set to zero) and stops sending ctl/data, it should resume operation
when the tester gives up its initial reservation.
• The DUT and INTD are allowed to stop demonstrating operation and/or beacon
transmission once the conflict is created.
Test Case 2.4: Conflicting Hard DRP Reservation – DUT/INTD Reservation Only
This test verifies that a DUT will not transmit in reservations advertised by other devices
when it receives beacons indicating reservations with conflicting types for the same
MAS. The tester reserves several rows of the SF that conflicts with the DUT/INTD
reservation. It transmits this reservation with the tiebreaker bit set to zero and a second
time with it set to one. In one of these cases the tester should "win", forcing the
DUT/INTD to relocate its reservation.
Test procedure:
1.
Start analyzer capture.
2. Test system starts transmitting a beacon with no reservations in slot 2. The BP
Length is set to 13.
3. Standard test start-up sequence.
4. The test system begins to transmit a beacon in slot 5 that contains DRP IEs that
reserve the top and bottom rows in the superframe. The reservation is of type
Hard DRP and the tiebreak bit is set to zero. When the test system joins, it sends
the beacon for slot 5 with the signaling slot bit set in a signaling slot 4 times.
5. One second later the test system stops sending a beacon in slot 5.
6. After 5 seconds the test system begins to transmit a beacon in slot 5 that contains
DRP IEs that reserve the top and bottom rows in the superframe. The reservation
is of type Hard DRP and the tiebreak bit is set to one. When the test system joins,
