Abstract
La presente invención se refiere a sistemas y métodos para usar dos portadores TDD en el mismo espectro apareado compensando las transmisiones de DL y UL en frecuencia para causar que los portadores TDD se comporten como dos portadores FDD de medio dúplex. Los períodos de transmisión y recepción de DL y UL se predefinen de modo que solamente uno de los portadores TDD se transmite en el DL en cualquier instante de tiempo mientras que el otro portador TDD se transmite en el UL.
