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 .
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.

For the Android phone, it could use the app: LTE Discovery, tap SIGNALS, check EARFCN(band number), ‘DL Freq and UL Freq’ .
Read moreWhat is band usage?
Each band has a defined upper and lower frequency limit. Because two radio transmitters sharing the same frequency band cause mutual interference, band usage is regulated . International use of the radio spectrum is regulated by the International Telecommunication Union (ITU).
Read moreWhat are bands in smartphone?
GSM and CDMA are frequency bands that support cellular service . While these letter jumbles may be unfamiliar, they can have a significant effect on phone carrier choice and can also affect phone type. With next-level networks being built, your current device might limit you depending on its model.
Read moreWhat does band mean in data?
In telecommunication, a band – sometimes called a frequency band – is a specific range of frequencies in the radio frequency (RF) spectrum, which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf).
