Wearable electronic devices and technologies - Part 801-2: Smart body area network (SmartBAN) - Low complexity medium access control (MAC) for SmartBAN (IEC 63203-801-2:2022)

This part of IEC 63203-801 specifies low complexity Medium Access Control (MAC) for SmartBAN.
As the use of wearables and connected body sensor devices grows rapidly in the Internet of Things (IoT), Wireless Body Area Networks (BAN) facilitate the sharing of data in smart environments such as smart homes, smart life etc. In specific areas of digital healthcare, wireless connectivity between the edge computing device or hub coordinator and the sensing nodes requires a standardized communication interface and protocols.
The present document describes the MAC specifications:
- Channel Structure,
- MAC Frame Formats,
- MAC functions.

L’IEC 63203-801-2:2022 spécifie un contrôle d'accès au support (MAC) à faible complexité pour SmartBAN.
Alors que l'utilisation des dispositifs de capteurs corporels prêts-à-porter et connectés s'accroît rapidement dans l'Internet des objets (IoT, Internet of Things), les réseaux corporels sans fil (BAN) facilitent le partage des données dans les environnements intelligents tels que les maisons intelligentes, la vie intelligente, etc. Dans des domaines spécifiques des soins de santé numériques, la connectivité sans fil entre le dispositif informatique périphérique ou le coordinateur du concentrateur et les nœuds de détection exige une interface et des protocoles de communication normalisés.
Le présent document décrit les spécifications relatives au contrôle d'accès au support (MAC) suivantes:

   
• structure du canal ;

   
• formats de trame MAC ;

   
• fonctions MAC.

Ta del standarda IEC 63203-801 določa nadzor dostopa do medija (MAC) za pametno telesno omrežje (SmartBAN).
Ker se uporaba nosljivih naprav in povezanih telesnih senzorjev v internetu stvari (IoT) hitro povečuje, brezžična telesna omrežja (BAN) poenostavijo skupno rabo podatkov v pametnih okoljih, kot so pametni domovi, pametno življenje itd. Na določenih področjih digitalnega zdravstvenega varstva brezžična povezljivost med napravo robnega računalništva ali koordinatorjem vozlišča in senzorskimi vozlišči zahteva standardiziran komunikacijski vmesnik in protokole.
Ta dokument opisuje specifikacije nadzora dostopa do medija:
– struktura kanalov;
– format okvirjev nadzora dostopa do medija;
– funkcije nadzora dostopa do medija.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 63203-801-2 has been prepared by IEC technical committee 124: Wearable electronic

INTRODUCTION
TC 124 is developing International Standards (IS) for body area network (BAN) to define the
wireless connectivity between the hub coordinator and the sensing nodes. The IEC 63203-801
series consists of the following sub-parts, under the general part title "Smart body area network
(SmartBAN)":
IEC 63203-801-1: Enhanced ultra-low power physical layer
IEC 63203-801-2: Low complexity medium access control (MAC) for SmartBAN
The present document describes the medium access control (MAC) specifications including
channel structure, MAC frame formats and MAC functions.
This document originates from the corresponding technical specification (ETSI TS 103 325)
standardized in the European Telecommunication Standard Institute (ETSI) and captures the
results the work of IEC TC 124 Working Group 4 on devices and systems. The current document
reflects contributions and discussions by IEC TC 124 experts, mirror committees, liaison
members and Joint Advisory Group (JAG) between IEC SyC. AAL, IEC TC 100 and IEC TC 124.
This document contains material gathered from reports and group output from the IEC TC 124
meetings in May 2018 (Manchester), October 2018 (Busan), May 2019 (San Francisco),
September 2019 (Shanghai), November 2020 (online) as well as information obtained during
various web meetings.
Experts from the following national committees, liaison organizations have contributed: BE, CN,
DE, FI, FR, GB, IN, JP, KR, MY, NL, US and ETSI TC SmartBAN.
This document is also positioned as a result of the activities of the JAG. At the IEC General
Meeting in Busan in 2018, three committees related to wearable systems and technologies,
SyC. AAL, IEC TC 100 and IEC TC 124 had a joint workshop and agreed to collaborate to
develop relevant standards and to share roles. This collaboration agreement was advanced to
a Joint Advisory Group (JAG) and the JAG was established managed by SyC. AAL in 2019.
The target audience for this document includes the following stakeholders who have an interest
in the systems and services using wearable devices:
• consumer electronics (CE) and information communications technology (ICT) device
manufacturers;
• system integrators who want to utilize wearable device and technologies;
• service operators who are interested in the AAL systems and services;
• stakeholders who want to understand the technologies and requirements for wireless
connectivity between wearable sensor nodes and hub coordinators.

5 General MAC framework
5.1 Different device types
Clause 5 provides the basic MAC framework for the nodes and hubs.
Two different device types can participate in SmartBAN:
1) sensor device (node); and
2) coordinator device (hub).
A hub is a device that acts as a SmartBA
