3. Notes

1)  A citation to the IEEE patent policy was provided with the announcement of the meeting. No one indicated being unfamiliar with the IEEE patent policy.

2)  The agenda was approved as presented.

3)  Resolution of comments

  1. 373: Defer. Apurva proposes to harmonize sub-sections 6.22, 6.23, 6.24, and 6.25 and Section 9 once the comments related to these sub-sections have been taken into account. However the group has not reached consensus on what parts should be modified and how to harmonize that. The guidelines for differentiating between sections 6 and 9 should be as follows, in the order of priorities:

-  Focus on discrepancy. Apurva to prepare a plan of action of what sub-section need to be modified

-  Avoid redundancy between sub-sections

-  Proper reference from one section to another to improve readability

Plan is for Apurva to present a plan for revising these sections and present it to the June teleconference session.

Apurva proposed to present a 'track change' version of section 9 and sections 6.22-25 with these changes.

Make sure that all interested people in sections 6 and 9 are available for the discussion.

Action: Apurva to work on this and present it.

  1. 374: Defer. See comment 373
  2. 375: Defer. See comment 373
  3. 377: Accept.
  4. 378: Defer. Section 6.24 has some discrepancy with 9.3 that need to be resolved: e.g., diagrams 118 and 119.

Action: Apurva is to review the block diagrams and validate is to consider augmenting section 9.3 with possible in-band sensing done by the SSA.

  1. 380: Defer. Text needs simplification. Only CDMA may be needed for UCS Notification since a 1 bit flag is sufficient to signal the presence of an incumbent in-band. [However, review of the documents reveald that the CDMA message need a minimum of three frames to react to the detectioon of an incumbent rather than one frame in the case of the contention-based message.]

Action: Gerald to send the ETRI document on CDMA vs contention UCS and BW request to Ranga, Jianfeng and Gwangzeen.

  1. 388: Defer. Need clarification. Sensing quiet periods should be given priority. There is a need for a convergence of quiet periods. Sub-section 6.24.2: synchronization of quiet periods need to be read to verify that the scheduling of the QPs is done in a self-coexistence situation. Apurva and Gerald to read section 6.24.2 to make sure that the scheme works.
  2. 389: Defer. Related to the on-demand frame contention algorithm. If TR comments cannot be resolved, then we could postpone it. Need to be re-visited later toward the July session
  3. 390: Defer. This will be part the harmonization of 6 and 9. See resolution of comment 373. [It was suggested that self-coexistence could be a separate section after the cognitive radio section 9.]

4)  Other business: No
