LTE yatejwe imbere kugirango ikore kuri spécran ya Frequency Division Duplex (FDD), hamwe na spekure idakoreshwa kuri Time Division Duplex (TDD).
Kugirango radiyo LTE yorohereze itumanaho ryibice byombi, birakenewe gushyira mubikorwa gahunda ya duplex kugirango igikoresho gishobora kohereza no kwakira nta kugongana.Kugirango ugere ku bipimo bihanitse byamakuru, LTE ikora duplex yuzuye aho itumanaho ryamanuka (DL) hamwe na uplink (UL) itumanaho riba icyarimwe mugutandukanya traffic DL na UL haba kuri frequency (urugero, FDD), cyangwa ibihe (urugero, TDD) .Mu gihe bidakorwa neza kandi bigoye cyane gukoresha amashanyarazi, FDD ikunda koherezwa cyane nababikora kubera kuvugurura gahunda ya 3G isanzwe.Mugereranije, gukoresha TDD bisaba spektrike nkeya kimwe no gukuraho noneho gukenera imirongo yizamu itanga uburyo bwiza bwo gutondekanya ibintu.Ubushobozi bwa UL / DL burashobora kandi guhindurwa muburyo bwo guhuza ibyifuzo gusa mugutanga umwanya mwinshi kuri umwe kurindi.Ariko, igihe cyo kohereza kigomba guhuzwa hagati ya sitasiyo fatizo, kigatangiza ibintu bigoye, hamwe nigihe cyo kurinda bisabwa hagati ya DL na UL subframes, bigabanya ubushobozi.
