Introduction Radio Resource Measurement is a key enabler to the next generation of Wireless LANs (WLAN
10、s). Radio Resource Measurement addresses some of the existing issues in using unlicensed radio environments to meet the requirements of emerging technologies. In addition, Radio Resource Measurement provides knowledge about the radio environment to improve performance and reliability. The existing W
11、LAN measurements and information about them are inadequate to move ahead to the next generation of WLAN. The proposed Radio Resource Measurement approach is to add measurements that extend the capability, reliability, and maintainability of WLANs through measurements and provide that information to
12、upper layers in the communications stack. In addition, there are new applications that require quantifiable radio environment measurements in order to attain the necessary performance. These applications include voice over Internet Protocol (VoIP), video over IP, location based applications, as well
13、 as applications requiring mitigation of harsh radio environments (multifamily dwellings, airplanes, factories, municipalities, etc.). WLAN Radio Resource Measurement addresses the MAC, the SME, the MLME primitives, the MIB, and the interface to upper layers. The Radio Resource Measurement scope is
14、to define Radio Measurements and to provide mechanisms to higher layers for radio and network measurements. This amendment provides these mechanisms using request/response queries and an Object Identifier (OID) interface to upper layers in the MIB. Notice to users Laws and regulations Users of these
15、 documents should consult all applicable laws and regulations. Compliance with the provisions of this amendment does not imply compliance to any applicable regulatory requirements. Implementers of the amendment are responsible for observing or referring to the applicable regulatory requirements. IEE

Patents Attention is called to the possibility that implementation of this amendment may require use of subject matter covered by patent rights. By publicati
25、on of this amendment, no position is taken with respect to the existence or validity of any patent rights in connection therewith. A patent holder or patent applicant has filed a statement of assurance that it will grant licenses under these rights without compensation or under reasonable rates, wit
26、h reasonable terms and conditions that are demonstrably free of any unfair discrimination to applicants desiring to obtain such licenses. Other Essential Patent Claims may exist for which a statement of assurance has not been received. The IEEE is not responsible for identifying Essential Patent Cla
27、ims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non
28、- discriminatory. Users of this amendment are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further information may be obtained from the IEEE Standards Association. Participants At the tim
