Abstract
Methods apparatuses and systems are provided for grant-less (GL) uplink transmissions. A wireless transmit/receive unit (WTRU) may receive a configuration of a set of GL Physical Uplink Shared Channel (GL-PUSCH) frequency resources. The WTRU may monitor for a downlink control information (DCI) message wherein the DCI message includes an indication of a presence of at least a subset of the set of GL-PUSCH frequency resources. If the WTRU successfully receives the DCI message the WTRU may select one or more GL-PUSCH frequency resources from the subset of the set of GL-PUSCH frequency resources and may select a time period. The WTRU may transmit data on a GL-PUSCH using the selected GL-PUSCH frequency resources during the selected time period. The WTRU may also monitor for hybrid automatic repeat request acknowledgement (HARQ-ACK) based on the selected GL-PUSCH frequency resources. The WTRU may monitor for the DCI during a fixed time window.
