Patent ID: 11838915

Abstract:
Embodiments of a user equipment (UE) configured for new-radio (NR) operations in a fifth-generation (5G) system (5GS) may be configured to detect a downlink-control information (DCI) format that includes a one-shot hybrid automatic repeat request acknowledgement (HARQ-ACK) request field and a frequency domain resource assignment field (FDRA). The one-shot HARQ-ACK request field may indicate whether one-shot HARQ-ACK feedback is triggered. The UE may decode the FDRA field to determine whether the FDRA field indicates a valid frequency resource or whether the FDRA field indicates a special value and may also be configured to determine whether or not a physical downlink shared channel (PDSCH) is scheduled by the DCI format and whether or not secondary cell (SCell) dormancy switching is triggered based on both the one-shot HARQ-ACK request field and the FDRA field. The UE may also encode a HARQ-ACK transmission on a physical uplink control channel (PUCCH). The HARQ-ACK transmission may be encoded to include HARQ-ACK feedback for PDSCH transmissions for all HARQ processes of a cell when the one-shot HARQ-ACK feedback is triggered.
