Verfahren, vorrichtung und systeme zur verbesserten uplink-datenübertragung auf konfigurierten berechtigungen

Abstract

Methods, apparatus and systems are disclosed. In one representative method, a wireless transmit / receive unit (WTRU) may receive information associated with one or more configured grants (CGs), may select a first CG corresponding to a first CG configuration, and may transmit, on a CG occasion associated with the first CG, a transport block (TB) using resources associated with the first CG. The WTRU may also start a CG timer for the first CG responsive to a transmission of the TB, and receive a HARQ Acknowledgement (ACK) indication indicating a HARQ-ACK feedback value and associated with a HARQ Process ID (PID) in Downlink Feedback Information (DFI) of Downlink Control Information (DCI). In this representative method, after reception of the HARQ ACK indication and on condition that a HARQ-ACK feedback value is equal to ACK, the WTRU may stop the CG timer and may flush a HARQ buffer associated with the HARQ PID.
