Abstract

a presente invenção revela um método de transmissão de pacote e equipamento de usuário. o método inclui: transmitir, por um nó de envio, múltiplos pacotes para um nó de recebimento; receber múltiplos pacotes de confirmação a partir do nó de recebimento; após determinar, com base nos múltiplos pacotes de confirmação recebidos, que um primeiro pacote está perdido, retransmitir o primeiro pacote; e caso seja detectado que o pacote retransmitido está perdido, retransmitir continuamente, pelo nó de envio, o primeiro pacote para o nó de recebimento em um intervalo de tempo predefinido pelo menos duas vezes. de acordo com as soluções da presente invenção, o pacote retransmitido pode ser detectado e recuperado a tempo após o pacote retransmitido ser perdido, reduzindo assim uma quantidade de vezes de retransmissão de tempo limite, aperfeiçoando uma taxa de transmissão, além disso, reduzindo uma probabilidade de perda de pacote de um pacote retransmitido, e reduzindo ainda mais uma probabilidade de retransmissão de tempo limite.
