Abstract

Método e dispositivo para alocar processos de requisição repetitiva híbrido-automática. Um método e um dispositivo para alocar os processos de requisição automática (ARQ)/ processos de requisição híbrido-automática (H-ARQ), em uma unidade de transmissão e recepção sem fio (WTRU), para que esta possa suportar transmissões de dados por meio de "uplink" avançado (EU: enhanced uplink). Depois que os parâmetros associados aos processos ARQ 1 H-ARQ são configurados, a WTRU aloca um processo ARQ/ H-ARQ para os dados que foram selecionados. Depois que os dados são transmitidos, a WTRU verifica se uma informação de retro-alimentação foi recebida. A WTRU então, irá liberar o processo ARQ/ H-ARQ se uma mensagem de reconhecimento (ACK) for recebida, ou então, irá retransmitir os dados, para o caso em que receba uma mensagem de não reconhecimento (NACK), ou então, que nenhuma retro-alimentação tenha sido recebida em um período de tempo pré-determinado, enquanto que incrementa um contador de transmissão na WTRU. Quando um limite na transmissão for atingido, a WTRU pode então descartar os dados, ou reiniciar a transmissão. Um processo ARQ 1 H-ARQ alocado para uma transmissão de baixa prioridade pode perder a precedência de transmissão para um outro processo que possua uma maior prioridade, quando não houver a disponibilidade de processos ARQ/ H-ARQ.
