  2. Proposed Resolution of D0 Comment S7-386 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  3. D0 Comment S7-386 • Place in document: subclause 7.13.2 ,line 35, page 115 • Comment: Clarification is necessary: In line 35-36, it is prohibited for the sender to transmit another PPDU.When will it be allowed ? On the conditon described in line 37-39? • Proposed Resolution:Clarfiy the logical connection between line35-36 and line 37-39 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  4. Proposed Resolution • Reject • Withdrawn by the commenter. • Editorial • Editorial change in line 37-39: “The sender shall ensure that its transmitted PPDUs containing either a MAC frame or the hybrid ARQ parity bits there of, …” Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  5. Proposed Resolution of D0 Comment S7-387 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  6. D0 Comment S7-387 • Place in the document: subclause 7.6.2, page 84 • Comment: A hub may employ improvised polling and posting access to send polls or posts at previously announced times based on Table 20 and as described below to grant polled or posted allocations, either in beacon mode or non-beacon mode as also noted in 7.3,It is not clear the difference between unscheduled access and improvised access, because both of them use (immediate) polls or (immediate) posts on Table 20.The purpose of this comment note is to explicitly clarify the definition of Improvised access. • Proposed Resolution: Possible Specification Change clause 7.6.2, page 84 : A hub may employ improvised polling and posting access to send polls or posts at previously announced times with future polls or future posts based on Table 20 and as described below to grant polled or posted allocations, either in beacon mode or non-beacon mode as also noted in 7.3, Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  7. Proposed resolution • Accepted in Principle • Add more explanation as shown in the supplement document • This makes little impact on the current document structure. Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  8. Alternative Resolution • Accepted in Principle • Currently unscheduled and improvised access is not exclusive each other. Thus, two subclauses are united as shown in the supplement document. Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  9. Proposed Resolution of D0 Comment S7-388 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  10. D0 Comment S7-388 • Place in Document: page 89, 7.7.1, line 20 , Editorial • Comment: Not relevant anymore • Proposed Resolution: to delete the phrase: or MSDU……till the end of the phrase Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  11. Proposed Resolution • Accept • Editorial • Use correct name of parameters and delete obsolete parameters as below In these IEs, the Minimum Length and Allocation Length fields, when present, shall have nonzero values. Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  12. Proposed Resolution of D0 Comment S7-392 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  13. D0 Comment S7-392 • Place in Document: Page 85, 7.6.2 Line 1 • Comment: There are two types of poll, one is immediate poll another is future poll.Unlike immediate poll, future poll does not have any information of polled allocation for the addressed node.The purpose of this comment note is to explicitly clarify the definition of immediate poll and future poll. Proposed Resolution: Additional explanation in Table 20 are as follows, -Immediate poll is to grant an immediate polled allocation to the node-Future poll is to inform the node of an intended future poll(immediate or future) or post. Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  14. Proposed Resolution • Reject • Already covered by the resolution of S7-387 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  15. Proposed Resolution of D0 Comment S7-393 Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  16. D0 Comment S7-393 • Place in Document: Page 109, 7.12.1 Line 8 • Comment : How do nodes identify RAP1 and RAP2 length at the very beginning superframe (BP 0) when beacon hopping is enabled? According to the description,RAP1 and RAP2 length field in the beacon of BPn refers BPn+1. What happened in the beginning ? (n+1 <- n<- n-1 <- … -<- 2 <- 1 <- 0 <-1 ?? ) • Proposed Resolution : If nodes do not need to know the RAP1 and RAP2 length at BP0 because it's a transient period, specify so. Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo

  17. Proposed Resolution • Accepted in principle. • Replace the last sentence in lines 8-9, page 109, with the following: “The RAP1 and RAP2 related fields contained in the beacon of the current beacon period now refer to the EAP1, RAP1, EAP2, and RAP2 in the next beacon period. A node does not know nor use these access phases in the beacon period in which it received its first beacon indicating beacon shifting is enabled, but it may use Type I and Type II access phases through polls and posts” Kaoru Yokoo, Jin-Meng Ho, Ichirou Ida, Hind Munzer-Chebbo
