State transitions for idle mode transmissions using pre-configured dedicated resources

A method for wireless communication, implemented at a terminal, comprising:

• receiving a first message comprising an indication of pre-configured dedicated resources for a communication between a network device and the terminal;
• and
• switching from an idle state to a data transmission state in an idle mode upon transmitting a second message over the pre-configured dedicated resources,
• wherein, in the idle state, the terminal is without an established radio resource control (RRC) connection, and
• wherein, in the data transmission state in the idle mode, the terminal is configured to:
• perform the communication with the network device over the pre-configured dedicated resources;
• and
• monitor a user-specific search space,
• wherein the pre-configured dedicated resources comprise a terminal-specific search space in the data transmission state in the idle mode (USS_IDLE),
• wherein the terminal monitors a physical downlink control channel (PDCCH) downlink control information (DCI) in a dedicated search space.

A wireless communication apparatus, comprising a processor configured to perform a method, the processor configured to:

• transmit a first message comprising an indication of pre-configured dedicated resources for a communication between a network device and a terminal;
• and
• receiving a second message over the pre-configured dedicated resources,
• wherein a transmission of the second message by the terminal causes the terminal to switch from an idle state to a data transmission state in an idle mode,
• wherein the terminal is without an established radio resource control (RRC) connection in the idle state,
• wherein the pre-configured dedicated resources comprise a terminal-specific search space in the data transmission state in the idle mode (USS_IDLE), and
• wherein the network device transmits a physical downlink control channel (PDCCH) downlink control information (DCI) in a dedicated search space.
