Communications system, infrastructure equipment, communication terminal and method

Circutiry for a communications terminal, the circuitry comprising:

• processing circuitry configured, in combination with a transmitter configured to transmit signals representing data via a wireless access interface and a receiver configured to receive signals via the wireless access interface, to
• receive data for transmission at a buffer,
• transmit a resource request message, the resource request message providing a request for resources of the wireless access interface for transmitting the buffered data, and
• receive a resource allocation message, the resource allocation message allocating resources of the wireless access interface to the communications terminal for transmitting the buffered data, wherein
• a characteristic of the resource request message transmitted by the communications terminal provides an indication of one of a predetermined set of transmission priority levels for transmitting the buffered data.

Circuitry for an infrastructure equipment for forming a mobile communications network, the circuitry comprising:

• processing circuitry configured, in combination with a transmitter configured to transmit signals to a communications terminal via a wireless access interface and a receiver configured to receive signals from the communications terminal, to
• receive a resource request message for requesting resources of the wireless access interface from the communications terminal for the communications terminal to transmit buffered data;
• allocate resources in the wireless access interface to the communications terminal in response to receiving the resource request message;
• generate a resource allocation message indicating the allocated resources;
• and
• transmit the resource allocation message to the communications terminal, wherein
• a characteristic of the resource request message received from the communications terminal provides an indication to the processing circuitry of one of a predetermined set of transmission priority levels for allocating resources of the wireless access interface to the communications terminal to transmit the transmitting the buffered data, and
• the processing circuitry is configured to allocate the resources based on the indicated priority level.
