Communications system, infrastructure equipment, communication terminal and method
First Claim
1. A communications system for communicating data to and from a communications terminal, the communications system comprising:
- infrastructure equipment configured to form a mobile communications network, the infrastructure equipment being configured to transmit data to and receive data from the communications terminal via a wireless access interface,the communications terminal being further configured;
to receive data for transmission to the infrastructure equipment at a buffer,to transmit a resource request message to the infrastructure equipment, the resource request message providing a request for resources of the wireless access interface for transmitting the buffered data to the infrastructure equipment, andto receive a resource allocation message from the infrastructure equipment, the resource allocation message allocating resources of the wireless access interface to the communications terminal for transmitting the buffered data,wherein the communications terminal is configured to transmit the resource request message to the infrastructure equipment using amplitude modulation, wherein a resource request message indicating a higher transmission priority level for transmitting the buffered data is transmitted with a higher signal amplitude, and a resource request message indicating a lower transmission priority level for transmitting the buffered data is transmitted with a lower signal amplitude.

Abstract
A communications system communicating data to/from a communications terminal includes infrastructure equipment forming a mobile communications network to transmit/receive data to/from the communications terminal via a wireless access interface, the communications terminal configured to transmit/receive data to/from the infrastructure equipment. The communications terminal can receive transmission data to the infrastructure equipment at a buffer, transmit a resource request message requesting resources of the wireless access interface to the infrastructure equipment in response to receiving the data for transmission to the infrastructure equipment, and receive a resource allocation message from the infrastructure equipment. The resource allocation message allocates resources of the wireless access interface to the communications terminal. A characteristic of the resource request message transmitted by the communications terminal to the infrastructure equipment provides an indication of one of a predetermined set of transmission priority levels for transmitting the buffered data to the infrastructure equipment.
