Systems and methods for grant-free uplink transmissions

A non-transitory tangible computer readable storage medium storing programming for execution by a processor, the programming including instructions to:

• receive from a network device a first type of uplink (UL) transmission resource assignment, wherein the first type of UL transmission resource assignment supports two types of signalling comprising radio resource control (RRC) signaling or a combination of a RRC signaling and dynamic signaling;
• and
• send to the network device, first data using grant free transmission;
• receive from the network device, a second type of UL transmission resource assignment, wherein the second type of UL transmission resource assignment supports dynamic signaling;
• and
• send to the network device, second data using grant based transmission.

A network system, comprising:

• a base station communicating with a first user equipment (UE) and a second UE;
• and
• the first UE is configured to:
• receive, from the base station, a first type of uplink (UL) transmission resource assignment, wherein the first type of UL transmission resource assignment supports two types of signalling comprising radio resource control (RRC) signaling or a combination of a RRC signaling and dynamic signaling;
• and
• send, to the base station, first data using grant free transmission, wherein the grant free transmission is a transmission mode without the first UE receiving scheduling grant for the first type of UL transmission resource from the base station;
• the second UE is configured to:
• receive, from the base station, a second type of UL transmission resource assignment, wherein the second type of UL transmission resource assignment supports dynamic signaling;
• and
• send, to the base station, second data using grant based transmission,
• wherein the grant based transmission is a transmission mode with the second UE receiving scheduling grant for the second type of UL transmission resource from the base station.
