Abstract
Sistemas y metodologías que facilitan la provision de un soporte para la formacion de haces en duplex por division de tiempo, en sistemas inalámbricos tradicionalmente no procesados en duplex por division de tiempo, tal como un sistema OFDMA, un sistema WCDMA, etc. De acuerdo con un aspecto, una estacion base puede analizar informacion de piloto tal como una porcion de ancho de banda sobre el cual un dispositivo usuario está trasmitiendo, y puede transmitir sobre el enlace descendente utilizando la porcion pre-saltada de ancho de banda utilizada por el dispositivo usuario en el intervalo de tiempo de enlace inverso precedente. La estacion base puede adicionalmente transmitir reasignaciones de segmentos de ancho de banda al dispositivo usuario a efectos de facilitar los altos de segmentos de ancho de banda entre dispositivos usuarios servidos por la estacion base. Adicionalmente, la estacion base puede dar instrucciones al dispositivo usuario para que provea a pedido informacion de piloto a efectos de resolver la ambigüedad relacionada con ello.
