摘要
1999年3月,在ITU-R TG8/1第16次会议上确定了IMT-2000无线接口参数;目前提交到ITU的IMT-2000地面无线传输技术提案已有10种。其中W-CDMA和cdma2000两种主流宽带CDMA技术仍在努力寻求标准的统一,我国提交的TD-SCDMA技术与3GPP的TDD方案也在积极探讨融合。标准融合尽管很困难,但仍存在着可能性。我国在考虑第三代移动通信采取的态度和策略时,应充分兼顾运营和产业界两方面的利益。
Key characteristics for the radio interface of the third mobile systems were approved in the sixteenth meeting of ITU - R TG8/1 in March 1999. More than ten terrestrial radio transmission proposals for IMT - 2000 have converged into hvo mainstream technologies, namely, W - CDMA and cdma2000. The TD - SCDMA system submitted by China and the TDD proposal from Europe are also seeking unification. The unification process of the standards, however, are negtively affected by a number of issues including IPR. Considerations should be given to both the operators and the industry for the deployment of the third mobile communications system in China.
