Hybrid automatic repeat request acknowledgment scheduling

Abstract

A wireless device receives one or more configuration parameters indicating a hybrid automatic repeat request (HARQ) feedback of a HARQ process is disabled. The wireless device receives a physical downlink shared channel (PDSCH) carrying a transport block (TB) corresponding to the HARQ process. Based on the HARQ feedback of the HARQ process being disabled, the wireless device determines a PDSCH processing time for the PDSCH. The wireless device transmits, via a physical uplink control channel (PUCCH), a HARQ acknowledgement of the TB, wherein a starting symbol of the PUCCH carrying the HARQ acknowledgment starts no earlier than the PDSCH processing time from a last symbol of the PDSCH.
