Abstract:

In order to satisfy the spectrum requirements of the next generation international mobile telecommunication (IMT)system,to realize scientific allocation and usage of spectrum resources and to avoid spectrum waste brought by allocation in advance,there is a need to make a reasonable estimation for the spectrum demands of future IMT systems.The estimation results can also provide guidelines for the subsequent spectrum planning and assignment work.The progress of study related IMT spectrum estimation was given.From the analysis of current work and practical situation,the key factors in the estimation methodology were summarized to provide a reference for the following work.

Key words: spectrum requirement, spectrum estimation, IMT system
