One exemplary method for wireless communication includes transmitting a first message comprising an indication of pre-configured terminal-specific dedicated resources for a communication between the network device and a terminal, and receiving information from the terminal over the pre-configured terminal-specific dedicated resources, wherein the terminal is in an idle mode and is without an established RRC connection. Another exemplary method for wireless communication includes receiving a first message comprising an indication of pre-configured terminal-specific dedicated resources for a communication between a network device and the terminal, and transmitting, while in the idle mode and without an established RRC connection, information over the pre-configured terminal-specific dedicated resources.
