Efficiently handling communications in wireless telecommunications systems

Integrated circuitry for network infrastructure equipment for, transmitting user plane data to a terminal device in a wireless telecommunications network when the terminal device is not in an active radio resource connected mode, wherein the integrated circuitry comprises controller circuitry and transceiver circuitry configured to operate together such that the network infrastructure equipment is operable to:

• transmit paging signalling to the terminal device, wherein the paging signalling comprises an indication the network infrastructure equipment has user plane data for transmission to the terminal device while the terminal device is not in an active radio resource connected mode and an indication of a set of radio resources on which the user plane data is to be transmitted by the network infrastructure equipment to the terminal device;
• and
• transmit the user plane data from the network infrastructure equipment using the indicated set of radio resources while the terminal device is not in an active radio resource connected mode.

A method of operating network infrastructure equipment for transmitting user plane data to a terminal device in a wireless telecommunications network when the terminal device is not in an active radio resource connected mode, the method comprising:

• transmitting paging signalling to the terminal device, wherein the paging signalling comprises an indication the network infrastructure equipment has user plane data for transmission to the terminal device while the terminal device is not in an active radio resource connected mode and an indication of a set of radio resources on which the user plane data is to be transmitted by the network infrastructure equipment to the terminal device;
• and
• transmitting the user plane data from the network infrastructure equipment using the indicated set of radio resources while the terminal device is not in an active radio resource connected mode.
