LTE yapangidwa kuti izigwira ntchito pa sipekitiramu yophatikizika ya Frequency Division Duplex (FDD), komanso mawonekedwe osalumikizana a Time Division Duplex (TDD).
Kuti mawayilesi a LTE athandizire kulumikizana kwapawiri, m'pofunika kukhazikitsa dongosolo laduplex kuti chipangizo chizitha kufalitsa ndikulandila popanda kugunda.Kuti akwaniritse kuchuluka kwa data, LTE imagwiritsa ntchito duplex yonse pomwe kulumikizana kwa downlink (DL) ndi uplink (UL) kumachitika nthawi imodzi ndikulekanitsa kuchuluka kwa magalimoto a DL ndi UL mwina pafupipafupi (ie, FDD), kapena nthawi (ie, TDD) .Ngakhale kuti ndizochepa komanso zovuta kwambiri zamagetsi kuti zigwiritsidwe ntchito, FDD imakonda kugwiritsidwa ntchito kwambiri ndi ogwira ntchito chifukwa cha kukonzanso makonzedwe a 3G omwe alipo.Poyerekeza, kutumiza TDD kumafuna mawonekedwe ocheperako komanso kuthetsa kufunikira kwa magulu a alonda omwe amalola kusungitsa bwino kwa sipekitiramu.Mphamvu ya UL/DL imathanso kusinthidwa kuti igwirizane ndi zomwe mukufuna pongopereka nthawi yochulukirapo yolumikizirana wina ndi mnzake.Komabe, nthawi yotumizira iyenera kulumikizidwa pakati pa masiteshoni oyambira, ndikuyambitsa zovuta, komanso nthawi yachitetezo yomwe ikufunika pakati pa ma DL ndi ma UL subframes, omwe amachepetsa mphamvu.
