Abstract

MéTODO E EQUIPAMENTO PARA CONTROLE DE LINK EM COMUNICAçõES SEM FIO. São revelados métodos e sistemas para uso em um sistema de comunicação 200 para retardar seletivamente a transmissão de uma segunda confirmação negativa (NAK) após uma NAK já ter sido enviada solicitando a retransmissão de um pacote corrompido. A entidade de recebimento 210 inicia um temporizador de proibir NAK 641 associado a uma NAK especifica 631 que evita que relatórios de situação para a entidade de transmissão 220 incluam uma retransmissão da NAK especifica até que o temporizador expire. O uso do temporizador de proibir NAK 641 reduz a probabilidade de retransmissões espúrias a partir da entidade de transmissão 220 causadas por uma segunda NAK a partir da entidade de recebimento 210 quando o processo de retransmissão já foi iniciado.
