A common simulation platform design for the evaluation and development of TDD IMT-Advanced Wireless Technologies and their co-existence study

当今无线技术演进的最强驱动力之一是4G（第四代），也称为高级IMT（国际移动的电信），其承诺包括两种主要的传统技术，即蜂窝（即，3GPP高级LTE）和WLAN（即，IEEE 802.16m）。4G承诺到2015年以更低的成本和更短的时间提供高速无线数据传输服务，同时提供更高的速率，频谱效率和覆盖范围。为了确保这些新一代无线技术在从现在起的几年内的最具成本/频谱效率的部署，它们的性能必须以更现实的方式通过仿真来可靠地评估，以便识别i）可以进行增强的区域，ii）引入这些增强并对其进行评估，iii）支持设备制造商在其标准化努力中集成这些增强（如果认为有价值的话），4.比较两种最重要的4G技术（参见（见上文），并评估它们的共存以及从一种技术向另一种技术的迁移对运营商的影响。正是从这个角度出发，华为加拿大公司要求申请人的团队在本提案的框架内开发一种新的通用仿真平台设计，用于下一代4G无线技术的TDD（时分双工）版本。

One of the strongest driving forces for wireless technology evolution today is 4G (4th Generation), also known as IMT-Advanced (International Mobile Telecommunications), which promises to encompass two main legacy technologies among others, namely cellular (i.e., 3GPP LTE-Advanced) and WLAN (i.e., IEEE 802.16m). 4G promises to deliver by 2015 high-speed wireless data transmission services at much lower costs and latencies while providing much higher rates, spectrum efficiencies and coverage. In order to ensure the most cost/spectrum-efficient deployment of these new-generation wireless technologies in a few years from now, their performance has to be reliably assessed by simulations in the more realistic way in order to identify i) areas where enhancements can be made, ii) introduce these enhancements and evaluate them, iii) support equipment manufacturers in their standardization effort to integrate these enhancements if deemed valuable, iv) compare the two most important 4G technologies (cf. above) due for deployment on a fair basis, using a common simulation platform, and assess the impact of their co-existence and the migration from one technology to another on operators. It is from this perspective, precisely, that Huawei Canada mandates the applicant's team to develop in the framework of this proposal, a novel common simulation platform design for the TDD (time division duplex) versions of next-generation 4G wireless technologies.
