2. Issues 43, 101
Problem: Some figures in 7.3 do not account for the intra-PAN subfield being equal to 1 and so do not contain the correct number of octets for the MAC header fields.
Proposed action: See slides 3-6.

3. Disassociation notification
Proposed action for 43, 101
MAC command
Src PANId
Dst PANId
Intra-PAN subfield
Octet count
Associate request
0xffff
desired PAN
No change
Associate response
macPANId 1 21
Disassociation notification
current PAN
PAN ID conflict
Orphan notification
No change*
* This is not necessarily an intra-PAN communication.

4. Proposed action for 43, 101 (continued)
MAC command
Src PANId
Dst PANId
Intra-PAN subfield
Octet count
Beacon request
No src addr
0xffff
No change
Coordinator realignment
macPANId
GTS request
No dst addr
Data request
-----
See slide 5-6

5. Proposed action for 43, 101: Data request
Data request command sent
after seeing address pended in beacon
following the ACK to a request command
on reception of MLME-POLL.request
Note 1: Currently, dest address comes from PIB parameters. When polling, dest address mode should equal mode used in MLME-POLL.request primitive.
Note 2: The MLME-POLL.request primitive does not restrict CoordPANId parameter to macPANId.

6. Proposed action for 43, 101: Data request (continued)
Src addr mode
Dst addr mode
Intra-PAN
Octet count
16b 1 9
64b
64b (Note 1) 21 15
n/a 7 13
If it is considered that a device may poll a coordinator on another PAN (Note 2), then more cases must be considered here.
