Here, there first EN-DC deployments that will use 4G LTE as an anchor will use 5G in the TDD variant first . For those network operators deploying 5G in 3. x GHz, 3GPP band n78 will be used, which is TDD. And for those network operators going for mmWave, TDD is also the only option.
Read moreWhat is TDD in 4G?
TDD means the transmission and reception occur on the same frequency , but each only for a split second, alternating between the two. That’s great for mobile Internet use, because you can use more of the bandwidth available for either downloading or uploading, whichever you happen to be doing.2 Ağu 2013
Read moreCan I combine FDD and TDD?
3GPP has finalized the work on TDD-FDD CA, which offers the possibility to aggregate FDD and TDD carriers jointly . The main target with introducing the support for TDD-FDD CA is to allow the network to boost the user throughput by aggregating both TDD and FDD toward the same UE.
Read moreWhat is the difference between TDD and FDD LTE?
LTE-FDD implies that downlink and uplink transmission take place in different, sufficiently separated, frequency bands, while TDD implies that downlink and uplink transmission take place in different, non overlapping time slots. Thus, TDD can operate in unpaired spectrum, whereas FDD requires paired spectrum .
