This is a WF for the phantom cell concept that they have been discussing for quite a while.<br /><br />The problem probably will be the signalling issues for cross component scheduling, but they don't have to use it at the beginning. As far as I can remember, each of the carrier component can formulate its own cell, and have different transmit power.Yutao Sui (via LTE / LTE-A 3GPP Rel-10-11-12 group on Linkedin)noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-19151686587846421772013-10-29T12:54:30.707+00:002013-10-29T12:54:30.707+00:00Hi, just to add a point , utilizing FDD can cover ...Hi, just to add a point , utilizing FDD can cover larger area and in the other side TDD can assign more downlink capacity, although for operators it is more useful to work with TDD but mostly they are working with FDD. <br />According to different requirements operators may use combination of both technologies as mentioned in previous comments :)Leyla Taghavifar (via LTE Advanced group on Linkedin)noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-54082534142068623712013-10-29T12:53:26.283+00:002013-10-29T12:53:26.283+00:00Hi Jianjun, thanks.

I am not sure whether any one will be going for this approach given the fact that CA on FDD alone has been such a struggle.Venkathttps://www.blogger.com/profile/15354420507577291472noreply@blogger.com
