Abstract

Se describen técnicas para transmitir datos con mitigación de interferencia de corto plazo en un sistema de comunicación inalámbrica; en un diseño, una primera estación (por ejemplo, una estación base o una terminal) puede enviar un primer mensaje al menos a una estación en interferencia para solicitar la reducción de interferencia en al menos un recurso; la primera estación puede enviar el primer mensaje en anticipación de recibir datos en al menos un recurso; una estación en interferencia puede recibir el primer mensaje desde la primera estación y puede reducir la interferencia en al menos un recurso reduciendo su potencia de transmisión y/u orientando su potencia en una dirección diferente de la primera estación; la primera estación puede entonces recibir datos desde una segunda estación en al menos un recurso; las técnicas pueden ser utilizadas para transmisión de datos en los enlaces de avance e inverso.
