Abstract

Se definen los formatos de acceso aleatorio (RA) para la operación NB-IoT en modo TDD. Se definen los formatos para permitir el uso de las configuraciones de subtrama LTE anteriores para TDD. Los formatos especifican un número P constante y predeterminado de grupos de símbolos que componen un preámbulo de RA, donde cada grupo de símbolos comprende un prefijo cíclico (CP) y un número X de símbolos; Los P grupos de símbolos se dividen en conjuntos de grupos de símbolos que se integran en 1 o 2 o 3 subtramas de enlace ascendente contiguas, en la que cada una de ellas comprende al menos dos grupos de símbolos transmitidos de manera adosada (es decir, contiguamente en el tiempo), y al menos dos conjuntos de grupos de símbolos se transmiten no contiguamente en el tiempo a través de un número de subtramas de enlace ascendente sobre las que se transmite el preámbulo de RA. El número de grupos de símbolos en un conjunto puede ser dos o tres; el número de grupos de símbolos es cuatro o seis, respectivamente. Los grupos de símbolos dentro de un conjunto se transmiten en subtramas de enlace ascendente adyacentes. Se definen cinco opciones de formatos, las que se asignan a diversas configuraciones LTE TDD.
