Systems and methods for signaling for semi-static configuration in grant-free uplink transmissions

A user equipment (UE) configured for grant free transmissions, the UE comprising:

• a processor;
• and
• a computer readable storage medium storing programming instructions for execution by the processor, the programming including instructions to:
• receive, from a network equipment, a radio resource control (RRC) signaling indicating an uplink grant-free transmission resource configuration, the configuration including a number of transmission repetitions K;
• receive, from the network equipment, a first downlink control information (DCI) message, wherein the first DCI message indicates that the UE is permitted to perform uplink grant free data transmissions and reference signal (RS) information indicative of an RS allocated to the UE;
• obtain uplink grant free transmission resources based on the uplink grant-free transmission resource configuration indicated in the RRC signaling and the first DCI message;
• and
• transmit, to the network equipment, uplink data using the uplink grant free transmission resources.
