An introduction to the proposed IEEE802.11k PICS proforma Simon Black, Hasse Sinivaara Nokia simon@motix.demon.co.uk, hasse.sinivaara@nokia.com Black/Sinivaara (Nokia)
What is a PICS? • A Protocol Implementation Conformance Statement • A statement of which capabilities and options of the protocol have been implemented • Has a number of uses by implementers, suppliers, testers & users • A completed PICS proforma is the PICS for the implementation in question • Much of this introduction is extracted from ISO/IEC 8802-11 Annex A Black/Sinivaara (Nokia)
What does a PICS look like? • From ISO-IEC 8802-11 Annex A • The main part of the PICS proforma is a fixed questionnaire, divided into sub-clauses, each containing a number of individual items. • Each item is identified by an item reference in the first column • The second column contains the question to be answered • The third column contains the reference or references to the material that specifies the item in the main body of the standard • The remaining columns record the status of each item, i.e., whether support is mandatory, optional, or conditional, and provide the space for the answers • Marking an item as supported is to be interpreted as a statement that all relevant requirements of the sub-clauses and normative annexes, cited in the References column for the item, are met by the implementation Black/Sinivaara (Nokia)
PICS Status Symbols • M Mandatory • O Optional • O.<n> Optional, but support of at least one group of options labelled by the same number <n> • Pred: conditional symbol, including predicate identification • A predicate is either: • An item-reference for an item in the PICS proforma: the value of the predicate is true if the item is marked as supported, and is false otherwise. • A boolean expression constructed by combining item-references using the boolean operator OR: the value of the predicate is true if one or more of the items is marked as supported, and is false otherwise. • Each item referenced in a predicate, or in a preliminary question for group conditional items, is indicated by an asterisk in the Item column • See ISO/IEC 8802-11 1999 Black/Sinivaara (Nokia)
What does a PICS look like? A.4.3 IUT configuration A.4.11 Radio Resource Measurement extensions Black/Sinivaara (Nokia)
