In FDD mode, uplink and downlink frames are both 10ms long and are separated either in frequency or in time. For full-duplex FDD, uplink and downlink frames are separated by frequency and are transmitted continuously and synchronously. For half-duplex FDD, the only difference is that a UE ...
FDD and TDD uplink transmissions have the same physical channels and signals. The only difference is that TDD frames include a special subframe, part of which can be used for SRS and PRACH uplink transmissions. The following illustration shows part of an LTE uplink frame and contains an allo...
These topologies are widely used in wireless communication systems such as WLAN, Fixed and Mobile WiMax, 4G LTE, 5G NR and so on. Let us compare FDD vs TDD and derive difference between FDD and TDD topologies used in mobile wireless communication. ...
TDD and FDD are two topologies by which critical resources time and frequency are shared among mobile subscribers or terminals. LTE uses both of these flavors to provide facility for the mobile subscribers or UEs to utilize the scarse resource efficiently based on the need. ...

specification, FDD/TDD separation for inDeviceCoexInd- UL-CA is not clear. Thus it is clarified that in inDeviceCoexInd-UL-CA capability, FDD/TDD difference follows signalling for inDeviceCoexInd capability. This means that if the UE supports inDeviceCoexInd-UL-CA for FDD/TDD only and ...

Since 4G Technology is becoming more and more known, most people may know TDD or FDD, but may not know the difference between the two technology clearly. It’s obevious that FDD LTE network is more commonly deployed and launched to commercial. So what’s the advantage of FDD-LTE 4G netwo...
