It studies the link budget calculation method in FDD LTE system, presents the values of the key parameters in link budget cal-culation, such as receiver sensitivity and interference margin, based on which an example of link budget is given. By compar-ing the coverage between LTE system and WCDMA system, it gives the coverage problems on deploying the LTE system on the existing WCDMA sites. Final y, it gives the suggestions on LTE deployment on the same sites.
