Abstract: Methods and systems for dynamically activate and deactivate an allocated resource for a UE to make grant-free uplink transmission are provided. In one embodiment, a user equipment (UE) receives a Radio Resource Control (RRC) signal. The RRC signal specifies grant-free (GF) configuration information. The GF configuration information comprises an activation field and at least one other GF resource configuration field. The activation field indicates whether the UE may perform GF uplink (UL) transmissions without waiting for a downlink control information (DCI) message. Then, the UE performs a GF UL transmission in accordance with the GF configuration information in the RRC signal.
