Rd., Taipei City, Taiwan. Voice: Fax: E-mail: 886-2-2739-9616 886-2-2378-2328 loa@nmi.iii.org.tw Venue: IEEE 802.16 Session #45, Mont Tremblant, Canada Base Document: None. Purpose: This contribution proposes to add “effective radio resource utilization index” to Performance Metric in IEEE 802.16j-06/013. Notice: This document has been prepared to assist IEEE 802.16. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. 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 802.16. IEEE 802.16 Patent Policy: The contributor is familiar with the IEEE 802.16 Patent Policy and Procedures <http://ieee802.org/16/ipr/patents/policy.html>, 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 <mailto:chair@wirelessman.org> 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 802.16 Working Group. The Chair will disclose this notification via the IEEE 802.16 web site <http://ieee802.org/16/ipr/patents/notices>. 1
  • 2. Introduction This contribution proposes to add “effective radio resource utilization index” to Performance Metric in IEEE 802.16j-06/013 “Effective system spectral efficiency” is defined as a system-wise performance parameter, however, it lacks of the granularity of multi-hop path and cannot be used to evaluate path selection schemes. The purpose of “effective radio resource utilization index” is to facilitate the evaluation of path selection schemes for MMR networks. 2
  • 3. Definition of Effective Radio Resource Utilization Index (ERUI) Effective radio resource utilization index (ERUI) is defined as the radio resource used to transmit the user data normalized by the radio resource used to transmit the same data using 64-QAM CC ¾ with repetition 1. The radio resource is limited to OFDMA slot. 3

  • 10. The MMR-cell ERUI In order to compare the performance of the path selection for the MMR-cell, the effective MMR-cell capacity is defined as     i i i i C MMR  cell   rMS in downstream  TDL   rMS in upstream  TUL i i i i where TDL and TUL denote the transmitting data amounts at i-th MS in unit of 64QAM CC ¾ with repetition 1 for DL and UL, respectively. 10
  • 11. Reference MMR-cell Capacity Moreover, reference MMR-cell capacity is defined as a reference of radio resource utilization (i.e. OFDMA slots) for data transmission when 64QAM CC ¾ with repetition 1 is used for all relay paths and access links. The value of the effective MMR-cell capacity shall be less than the reference MMR-cell capacity. The optimized path selection for all MSs via relay paths in an MMR cell is to maximize the effective MMR-cell capacity. 11
