Resource management, access control and mobility for grant-free uplink transmission

A method for wireless communication at a base station, comprising:

• configuring a set of resources for a user equipment (UE) to use for grant-free uplink transmissions while the UE is operating in a disconnected state;
• transmitting a connection release message that includes a resource indicator to the UE, the resource indicator indicating the set of resources configured for the UE, the connection release message transitioning the UE from a connected state to the disconnected state;
• receiving, while the UE is operating in the disconnected state, the grant-free uplink transmissions from the UE using the set of resources configured for the UE;
• and
• transmitting, to the UE, a transition request message indicating a request for the UE to transition to the connected state directly from the disconnected state.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the UE to:
• receive a connection release message from a base station, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state;
• transition from a connected state to the disconnected state based at least in part on the connection release message;
• perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources;
• receive, from the base station, a transition request message indicating a request for the UE to transition to the connected state directly from the disconnected state;
• and
• transition to the connected state directly from the disconnected state based at least in part on the transition request message.
