3. Notes

1)Gerald recorded the attendance at 8:07PM EDT.

2)A citation to the IEEE patent policy was provided with the announcement of the meeting. When asked, no one notified the chairman that they were unfamiliar with the IEEE patent policy.

3)The agenda was approved unanimously.

4)The following Ranging comments were reviewed:

  1. Comment 217: Gwangzeen Ko has produced document #08-309r0 providing the rationale for using a 16-bit timing adjustment IE for the ranging. There is no need for 32 bits. The maximum range that this variable needs to cover is 2 times 100 km, that is 2 symbols at the most, resulting in about 5000 sampling periods which can be coded with 13 bits. Ivan indicated that there is a need to look at the total round-trip delay including the time at the CPE and the BS for signal processing. It was concluded that these extra times would be counted in number of symbols and would have to do with the BS scheduling rather than the ranging offset in sampling periods.
    Ivan indicated that there is a need for knowledge at the BS on the processing time needed at the CPE so that the BS can schedule the CPE response with the proper delay. Each CPE implementation should not have complete freedom on this processing delay. A CPE shall be able to respond within x symbols so that the scheduling algorithm at the BS can be done. This will probably need to be specified in the standard. The comment was rejected.
  2. Comment 347: Jung Sun provided the text for this resolution in document #09-063. The group agreed with the following modification: “First, a CPE shall synchronize to the downstream superframe and frame preamble. Counter.
  3. Comment 372: Action: Gwangzeen Ko had provide a clarification in document # 08-310r0 explaining the pros&cons of CDMA and contention-based ranging. It was concluded that the non-CDMA based periodic ranging scheme (i.e., contention based) is not needed. The action was to remove item e) from the list:"Using the OFDMA ranging mechanism, the periodic ranging timer (T4) is controlled by the CPE, not the BS." B
  4. Comment 142: Apurva suggested to review this comment on the inclusion of the two EKS bits in the proper filed in the Table. Dave indicated that he had kept this two bits in his proposal contained in document #8-240r1. This was agreed. Counter.

5)There was no other business.
