I-LTE iye yaphuhliswa ukuba isebenze kwi-spectrum edibeneyo ye-Frequency Division Duplex (FDD), kunye ne-spectrum engasebenziyo ye-Time Division Duplex (TDD).
Ukuze inkqubo yerediyo ye-LTE iququzelele unxibelelwano olumacala omabini, kuyimfuneko ukuphumeza iskimu se-duplex ukuze isixhobo sisasaze kwaye sifumane ngaphandle kokungqubana.Ukuze kuphunyezwe amazinga aphezulu edatha, i-LTE isebenza ngokuphindwe kabini apho zombini i-downlink (DL) kunye ne-uplink (UL) unxibelelwano lwenzeka ngaxeshanye ngokwahlula i-DL kunye ne-UL traffic mhlawumbi ngokuphindaphindiweyo (okt, FDD), okanye amaxesha exesha (okt, TDD) .Ngelixa ingasebenzi kakuhle kwaye inzima kakhulu yombane ukuhambisa, i-FDD ithande ukuhanjiswa ngokuqhelekileyo ngabaqhubi ngenxa yokwenziwa ngokutsha kwamalungiselelo akhoyo e-3G.Ngokuthelekisa, ukubeka i-TDD kufuna i-spectrum encinci kunye nokuphelisa imfuneko yeebhendi zoonogada ezivumela ukupakishwa okusebenzayo ngakumbi kwe-spectrum.Umthamo we-UL/DL unokuhlengahlengiswa ukuze ungqinelane nemfuno ngokulula ngokunikela ixesha lomoya elingakumbi kwelinye phezu kwelinye.Nangona kunjalo, ixesha lothumelo kufuneka lihambelane phakathi kwezikhululo ezisisiseko, ukwazisa ubunzima, kunye namaxesha okugada afunekayo phakathi kwe-DL kunye ne-UL subframes, enciphisa umthamo.
