LTE is able to utilise both frequency division and time division, FDD & TDD (TD-LTE) forms of duplex to accommodate the uplink and downlink. LTE can utilise both FDD – frequency division duplex and TDD – time division duplex, often referred to as TD-LTE.
Read moreWhat is FDD and TDD in 4G?
FDD LTE stands for Frequency-Division Duplexing LTE . Both TDD and FDD differ in the way they treat data. Duplexing means a phone can transmit and receive simultaneously. TDD means the “receive” and “transmit” channels divide the time between them on the same frequency band.
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 .
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.
