September 2014 doc.: IEEE 802.11-yy/xxxxr0 September 2014 Abstract Some comments received in response to LB201 have suggested that an Annex describing how the various optional FILS elements/indicators in the FD frame and the beacon may be used. Xaiofei WANG, InterDigital Xaiofei WANG, InterDigital

FILS Elements for System Use September 2014 doc.: IEEE 802.11-yy/xxxxr0 September 2014 FILS Elements for System Use E.g., CID 4911 comments: Add an Annex to explain the system requirements for FILS. Some of the text in the Procedure clause (10.44, D2.0) provided information about frame elements which has no MAC procedures associated with them These elements have higher layer and implementation “procedures” which they can enable. But, these “procedures” are not in the scope of 802.11. These redundant element descriptions in the Procedures clause are proposed to be removed, as the elements are defined in the Frames clause. Hence, the standard does not provide insight on how to use these elements. Previous amendments have addressed this issue by adding an Annex which describes the suggested “procedures”, e.g., GAS provided Annex V Interworking with external networks.
