May 2004 doc. : 15 -04 -0490 -00 -004 b 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. Submission 2 Monique Brown, Motorola, Inc.

May 2004 doc. : 15 -04 -0490 -00 -004 b Proposed action for 43, 101 MAC command Src PANId Dst PANId Intra-PAN subfield Octet count Associate request 0 xffff desired PAN 0 No change Associate response mac. PANId 1 21 Disassociation notification current PAN 1 21 PAN ID conflict mac. PANId 1 21 Orphan notification 0 xffff 0 No change* * This is not necessarily an intra-PAN communication.

May 2004 doc. : 15 -04 -0490 -00 -004 b Proposed action for 43, 101 (continued) MAC command Src PANId Dst PANId Intra-PAN subfield Octet count Beacon request No src addr 0 xffff 0 No change Coordinator realignment mac. PANId 0 xffff 0 No change GTS request mac. PANId No dst addr 0 No change Data request ----- See slide 5 -6 Submission 4 Monique Brown, Motorola, Inc.

May 2004 doc. : 15 -04 -0490 -00 -004 b 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 Coord. PANId parameter to mac. PANId.

May 2004 doc. : 15 -04 -0490 -00 -004 b Proposed action for 43, 101: Data request (continued) Src addr mode Dst addr mode Intra-PAN Octet count 16 b 1 9 64 b (Note 1) 1 21 16 b 64 b (Note 1) 1 15 64 b 16 b 1 15 16 b n/a 0 7 64 b n/a 0 13 If it is considered that a device may poll a coordinator on another PAN (Note 2), then more cases must be considered here.
