Abstract
Terminal para realizar un procedimiento de acceso aleatorio en un sistema de comunicación inalámbrica, comprendiendo el terminal: un transceptor adaptado para recibir un comando para iniciar un temporizador de alineación temporal que se utiliza para controlar cuánto tiempo se considera el terminal como una alineación temporal de enlace ascendente; en el que el comando es un comando de avance temporal (TAC), y el comando de avance temporal es recibido en un mensaje de respuesta de acceso aleatorio; y un procesador adaptado para determinar si un preámbulo de acceso aleatorio en el procedimiento de acceso aleatorio se indicó de manera explícita y un índice del preámbulo de acceso aleatorio no era 00000; en el que si se determina que el preámbulo de acceso aleatorio se indicó explícitamente y el índice del preámbulo de acceso aleatorio no era 00000, se aplica el comando de avance temporal, y el temporizador de alineación temporal se inicia o se reinicia, en el que si se determina que el preámbulo de acceso aleatorio no se indicó explícitamente y si el temporizador de alineación de tiempo no se está ejecutando, se aplica el comando de avance temporal, y se inicia el temporizador de alineación temporal; en el que se detiene el temporizador de alineación temporal cuando una resolución de contienda se considere infructuosa, y en el que si se determina que el preámbulo de acceso aleatorio no se indicó explícitamente y el temporizador de alineación temporal se está ejecutando, se ignora el comando recibido.
