Hi Experts.

Does anyone have information on the maximum continuous LTE TDD band 40 that can be aggregated?

Should be 5 x 20MHz.

20+20 or 20+10 or 15+15 also.

Can I have 20 + 20 + 20 +10 TDD CA combination, for contiguous spectrum?

According to 3gpp upto 500 prb (5x20Mhz) can be aggregated using band class F.

In your case, for a contiguous 350prb it has to be defined as CA band class E.

The eNodeB supports a maximum of 8 CC. The number of CCs that can take effect depends on the UE capability

CA<=5 carriers: FDD or TDD both can be Pcell

CA>5 carriers: Pcell must be FDD.

As you were asking about contiguous for Band 40:
