3. doc.: IEEE 802.15-10-0xxx-00-0007 Submission July 2010 Joachim W. Walewski, Siemens AGSlide 3 Background T-CID 190 by Sridhar Rajagopal: I understand we agreed to support CSK color stabilization- but this negotation response information element is NOT required. We already have two bits in the capabilities IE to indicate the Table 86. Recommend deleting this subclause 6.2.3.5 and using Table 78 as a reference for the two bits in Table 86. do as comment. Change text on line 30, page 148 to use details provided in Table 86. Merge Table 86 as part of Table 78 (similar to Table 79 …) but Tables 84 and 85 along with the rest of 6.2.3.4 should be deleted.

5. doc.: IEEE 802.15-10-0xxx-00-0007 Submission July 2010 Joachim W. Walewski, Siemens AGSlide 5 Lets see if I understand Sridhar Our proposal: (1) tell coordinator about whether is set up for colour stabilisation in the CSK Rx mode

6. doc.: IEEE 802.15-10-0xxx-00-0007 Submission July 2010 Joachim W. Walewski, Siemens AGSlide 6 Lets see if I understand Sridhar Our proposal: (2) the coordinator tells whether it will use devices colour-stabilisation capability and whether the device will be tasked to stabilise its colour (by relying on stabilisation information from the coordinator)

Walewski, Siemens AGSlide 7 Lets see if I understand Sridhar Our proposal: (2) the coordinator tells whether it will use devices colour-stabilisation capability and whether the device will be tasked to stabilise its colour (by relying on stabilisation information from the coordinator)

9. doc.: IEEE 802.15-10-0xxx-00-0007 Submission July 2010 Joachim W. Walewski, Siemens AGSlide 9 Lets see if I understand Sridhar Sridhars proposal (as I understand it): (1) tell coordinator about whether is set up for colour stabilisation in the CSK Rx mode; skip step (2)

10. doc.: IEEE 802.15-10-0xxx-00-0007 Submission July 2010 Joachim W. Walewski, Siemens AGSlide 10 If I got the Sridhars recommendation right … How is the coordinator supposed to tell the device that It is not interested in colour stabilisation? It is solicits the device to stabilise and that it will assist the device in so doing?
