Abstract

Se describen t?cnicas para transmitir datos con retransmisi?n autom?tica h?brida (HARQ - hybrid automatic retransmission) y atenuaci?n de interferencia. En un dise?o, un transmisor procesa un paquete de datos de acuerdo con una tasa y env?a al menos una transmisi?n del paquete a un receptor con HARQ. En un dise?o, el transmisor le env?a un mensaje activador al receptor para enviar una solicitud a fin de reducir la interferencia a la(s) estaci?n(es) interferentes. El transmisor puede enviar una primera transmisi?n del paquete (i) despu?s del mensaje activador, por ejemplo, en tramas consecutivas de un solo entrelazado de HARQ, (ii) junto con el mensaje activador en la misma trama. El n?mero de transmisiones a enviar para el paquete puede ser dependiente de si la(s) estaci?n(es) interferente(s) reducen la interferencia al receptor. La transmisi?n de paquete puede terminar con anticipaci?n si la atenuaci?n de interferencia es exitosa o puede terminar posteriormente si la atenuaci?n de interferencia no es exitosa.
