Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair stuart@ok-brit.com as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group.

2. doc.: IEEE 802.11-07/2215r1 Submission July 2007 Ganesh Venkatesan, Intel CorporationSlide 2 Abstract This document is a submission for Supported Radio Resource Measurement Bitmask Information Element. Corresponding normative text is in document 07/xxxxr0. This proposal addresses CID #12 (LB96#25-Palm):There are too many varied procedures here. It is unlikely that implementations will implement all of the procedures. Each of the supported procedures/reports should be separately indicated and negotiated

3. doc.: IEEE 802.11-07/2215r1 Submission Rationale 802.11k is a collection of measurement tools Some measurements require additional resources and devices may choose not to implement them When a device advertises support for 802.11k (dot11RadioMeasurementEnabled is TRUE), it is not clear what RRM is supported (and enabled) and what is not supported A STA will have to send one or more measurement requests and analyze the received reports to comprehend what the measuring STA is capable of A simple method is to advertise supported measurements via a Supported RRM Bitmask IE July 2007 Ganesh Venkatesan, Intel CorporationSlide 3

11. doc.: IEEE 802.11-07/2215r1 Submission Normative Text Changes Minimal change to the amendment: –Define Radio Resource Measurement Capability IE –Add the IE to Probe Request, Probe Response, Association Request and Reassociation Request frames –Fix Clause 11.10.5 to describe the semantics of the bits in the Capability IE: bit set implies that the station will never respond (for the duration of the current association) to the request with a report indicating that it is ‘incapable’ of performing the measurement. A STA receiving a measurement request that it advertises to support in the Capability IE can always respond with a report indicating that it is ‘refusing’ to perform the measurement. –Fix Annex-A July 2007 Ganesh Venkatesan, Intel CorporationSlide 11
