Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, 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. If you have questions, contact the IEEE Patent Committee Administrator at <patcom@ieee.org>. Ganesh Venkatesan, Intel Corporation Emily Qi et al

Month Year November 2005 July 2007 Abstract This document is a submission for Supported Radio Resource Measurement 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 seperately indicated and negotiated Ganesh Venkatesan, Intel Corporation Emily Qi et al

Rationale 802.11k is a collection of measurement tools July 2007 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 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 Ganesh Venkatesan, Intel Corporation

Supported RRM Bitmask IE Month Year November 2005 July 2007 Supported RRM Bitmask IE Bits in the IE Indicate which of the RRMs are supported by the STA MIB attribute dot11RadioMeasurementEnabled = TRUE means Capability Information Field:12 is set that the STA is capable of receiving a RRM request and respond to it Is present in Probe Request, Probe Response, [Re]Association Request and [Re]Association Response if dot11RadioMeasurementEnabled is TRUE Adds 5 octets to the above frames Ganesh Venkatesan, Intel Corporation Emily Qi et al

Normative Text Changes July 2007 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.
