Abstract

método implementado por uma unidade de transmissão/recepção sem fio, e, unidade de transmissão/recepção sem fio. a presente invenção se refere a métodos e a um aparelho para transmitir um reconhecimento de solicitação de repetição automática híbrida (harq-ack- hybrid automatic repeat request acknowledgment). uma unidade de transmissão/recepção sem fio (wtru) pode transmitir uma mensagem a de canal de acesso aleatório (rach) para um gnb. a wtru pode receber uma mensagem b de rach do gnb em resposta à mensagem a e a mensagem b pode compreende informações de controle de enlace descendente (dci- downlink control information). a wtru pode decodificar um canal físico compartilhado de enlace descendente (pdsch - physical downlink shared channel) com base na dci. a wtru pode determinar que a resolução de contenção foi bem-sucedida. a wtru pode determinar um recurso para um canal físico de controle de enlace ascendente (pucch). a wtru pode transmitir um harq-ack através do recurso de pucch determinado. a wtru pode determinar o recurso para o pucch com base em um índice de recurso de pucch. o índice de recurso de pucch pode ser baseado em um índice de preâmbulo de acesso aleatório (rapid) e em um indicador de recurso de pucch (pri).
