2. doc.: IEEE 802.11-07/2215r4 Submission August 2007 Ganesh Venkatesan, Intel CorporationSlide 2 Abstract This document is a submission for Radio Resource Measurement Capability Enabled Bitmask Information Element. Corresponding normative text is in document 07/2285r0. This proposal addresses part of CID #12 (LB96#25-Palm) and SB CID #421: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* * Not Addressed by this submission

3. doc.: IEEE 802.11-07/2215r4 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 RRM capability via a RRM Capability Enabled Bitmask IE August 2007 Ganesh Venkatesan, Intel CorporationSlide 3

12. doc.: IEEE 802.11-07/2215r4 Submission Normative Text Changes Minimal change to the amendment: –Define Radio Resource Measurement Capability IE –Add the IE to Probe Response, Association Request and Reassociation Request frames –Fix Clause 11.10.5 to describe the semantics of the bits in the RRM Capability Enabled 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 –Fix Annex-D August 2007 Ganesh Venkatesan, Intel CorporationSlide 12
