aluation guidelines and method- ology specified by the ITU-R Working Party 5D. The following section describes the simulation assumptions and configuration parameters that were used in the evaluation of the IEEE 802.16 technology using full-buffer data and VoIP traffic models. In addition to the common configuration parameters (technology agnostic) that were specified in Report ITU-R M.2135-1, technology-specific and test-environment-specific configuration parameters were assumed in the link-level and system- level simulations to maximize the system performance in the scenarios of interest; therefore, the configuration parameters may vary across different test environments. Note that the downlink to uplink ratio is 5:3, i.e., 5 downlink subframes and 3 uplink subframes, for the TDD mode for all full-buffer data simulations, and the cyclic prefix of 1/16 is used.
