Abstract

Se divulgan aparatos, métodos, y sistemas para conmutación de haz después del procedimiento de LBT. Un aparato (500) incluye un procesador (505) y un transceptor (525) que opera en el espectro no autorizado, en donde el transceptor (525) soporta una pluralidad de paneles de dispositivo. El procesador (505) ejecuta (805) un primer procedimiento de Escuchar-Antes-De-Hablar ("LBT") utilizando detección omni-direccional para adquirir un primer Tiempo de Ocupación de Canal ("COT") y ejecuta (810) una primera transmisión de enlace ascendente de un primer bloque de transporte ("TB") durante el primer COT y utilizando un primer panel de dispositivo en respuesta a LBT exitoso. Aquí, la primera transmisión de enlace ascendente utiliza una primera porción del primer COT. El procesador (505) ejecuta (815) un procedimiento de LBT direccional para que un segundo panel de dispositivo adquiera una porción remanente del primer COT.
