Communications devices and methods

Abstract

Communicating in a wireless telecommunications system comprising a communications device and one or more infrastructure equipment, wherein the communications device is configured to communicate with the infrastructure equipment via a first wireless access interface in accordance with a first radio access technology (RAT) and to communicate with the infrastructure equipment via a second wireless access interface in accordance with a second RAT. An exemplary process includes receiving, at the communications device via the first wireless access interface, control signalling from one of the infrastructure equipment, the control signalling comprising an indication of first communications resources to be used by the communications device to communicate via the second wireless access interface, and transmitting, from the communications device, the signals representing data to and/or receiving, at the communications device, the signals representing data from, using the first communications resources, the one of the infrastructure equipment via the second wireless access interface.

What is claimed is: 
     
         1 . A method of operating a communications device in a wireless telecommunications system comprising one or more infrastructure equipment, wherein the communications device is configured to transmit signals to and receive signals from the infrastructure equipment via a first wireless access interface in accordance with a first radio access technology, RAT, and to transmit signals to and receive signals from the infrastructure equipment via a second wireless access interface in accordance with a second RAT, the second RAT being different to the first RAT, the method comprising
 receiving via the first wireless access interface control signalling from one of the infrastructure equipment, the control signalling comprising an indication of first communications resources to be used by the communications device to transmit/receive signals representing data to/from the one of the infrastructure equipment via the second wireless access interface, and   transmitting the signals representing data to and/or receiving the signals representing data from, using the first communications resources, the one of the infrastructure equipment via the second wireless access interface.   
     
     
         2 . A method of operating a communications device in a wireless telecommunications system comprising one or more infrastructure equipment, wherein the communications device is configured to transmit signals to and receive signals from the infrastructure equipment via a first wireless access interface in accordance with a first radio access technology, RAT, and to transmit signals to and receive signals from the infrastructure equipment via a second wireless access interface in accordance with a second RAT, the second RAT being different to the first RAT, the method comprising
 transmitting via the first wireless access interface control signalling to one of the infrastructure equipment, the control signalling comprising physical uplink control information to be used by the one of the infrastructure equipment, the physical uplink control information relating to the second RAT.   
     
     
         3 . Circuitry for a communications device configured to communicate with a wireless telecommunications network comprising one or more infrastructure equipment, the communications device comprising
 transmitter circuitry configured to transmit signals to the infrastructure equipment via a first wireless access interface in accordance with a first radio access technology, RAT, and to transmit signals to the infrastructure equipment via a second wireless access interface in accordance with a second RAT, the second RAT being different to the first RAT,   receiver circuitry configured to receive signals from the infrastructure equipment via the first wireless access interface in accordance with the first RAT, and to receive signals from the infrastructure equipment via the second wireless access interface in accordance with the second RAT, and   controller circuitry configured to control the transmitter circuitry to transmit the signals and to control the receiver circuitry to receive the signals, the controller circuitry being configured in combination with the transmitter circuitry and the receiver circuitry,   to transmit via the first wireless access interface control signalling to one of the infrastructure equipment, the control signalling comprising physical uplink control information to be used by the one of the infrastructure equipment, the physical uplink control information relating to the second RAT.
