LTE yakagadziridzwa kuti ishande papaired spectrum yeFrequency Division Duplex (FDD), uye isina kupetwa spectrum yeTime Division Duplex (TDD).
Kuti LTE redhiyo system ifambise kutaurirana kweviri, zvinodikanwa kuita duplex scheme kuitira kuti mudziyo utumire nekugamuchira pasina kudhumhana.Kuti uwane huwandu hwehuwandu hwe data, LTE inoshandisa duplex yakazara apo zvese zviri zviviri downlink (DL) uye uplink (UL) kutaurirana kunoitika panguva imwe chete nekuparadzanisa DL uye UL traffic kungave nekuwanda (kureva, FDD), kana nguva (kureva, TDD) .Kunyange zvazvo zvisinganyanyi kushanda uye zvakanyanya kuoma kushandiswa kwemagetsi kushandiswa, FDD inowanzonyanya kushandiswa nevashandisi nekuda kwekugadzirisa zvakare zvirongwa zve 3G spectrum zviripo.Kana tichienzanisa, kuendesa TDD kunoda kushoma spectrum pamwe nekubvisa ipapo kudiwa kwemabhendi evarindi achibvumira kukwenenzverwa kwezviratidziro.UL / DL huwandu hunogonawo kugadziridzwa zvine simba kuti ienderane nezvinodiwa nekungopa yakawanda airtime kune imwe pamusoro peimwe.Nekudaro, nguva yekufambisa inofanirwa kuwiriraniswa pakati pezviteshi zvepasi, kuunza kuomarara, pamwe nenguva dzevarindi dziri kudiwa pakati peDL neUL subframes, izvo zvinoderedza huwandu.
