Abstract

MÉTODO PARA USO EM UMA UNIDADE DE TRANSMISSÃO/RECEPÇÃO SEM FIO, E, UNIDADE DE TRANSMISSÃO/RECEPÇÃO SEM FIO. Trata-se de métodos e aparelhos para retroinformação seletiva de solicitação de repetição automática híbrida (HARQ) de evento único por nível de prioridade. Por exemplo, uma unidade de transmissão/recepção sem fio (WTRU) pode determinar uma prioridade associada a cada bloco de transporte (TB). Cada TB pode corresponder aos respectivos processos de HARQ associados a transmissões de enlace descendente a partir de uma estação-base (BS). A WTRU pode receber, da BS, uma solicitação para a retroinformação de HARQ de evento único com uma indicação de uma prioridade selecionada para a retroinformação de HARQ de evento único. A WTRU pode gerar um dicionário de códigos HARQ para transmissão da retroinformação de evento único. O dicionário de códigos HARQ pode compreender um ou mais bits de informação correspondentes a um ou mais TBs determinados com base na prioridade indicada. A WTRU pode determinar, com base no número de um ou mais bits de informação, uma potência de transmissão e transmitir, na potência de transmissão, a retroinformação de evento único que compreende o dicionário de códigos HARQ gerado.
