Project: IEEE 802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Proposals for 802.15.4 MAC Issues] Date Submitted: [12 Sept 2004] Source: [Monique Bourgeois Brown] Company [Motorola, Inc.] Address [1150 Kifer Road, Sunnyvale, CA 95131, USA] Voice:[+1 408 991 7460], E-Mail: [m.bourgeois@motorola.com] Re: [15-04-0234-11-4b] Abstract: [Summary proposals for 802.15.4 Issues] Purpose: [To focus resolutions for 802.15.4 MAC Issues.] Notice: This document has been prepared to assist the IEEE 802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by 802.15. Monique Brown, Motorola, Inc.

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. Monique Brown, Motorola, Inc.

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. Monique Brown, Motorola, Inc.

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 Monique Brown, Motorola, Inc.

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. Monique Brown, Motorola, Inc.

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. Monique Brown, Motorola, Inc.
