Claim of US Patent No. 10,798,719

1. A communications device configured to transmit signals to and/or receive signals from an infrastructure equipment of a mobile communications network, the communications device comprisinga receiver configured to receive signals transmitted by the infrastructure equipment,
a transmitter configured to transmit signals to the infrastructure equipment, and
a controller configured to control the transmitter and the receiver to receive data from the infrastructure equipment, wherein the mobile communications network forms a wireless access interface, and the transmitter and the receiver are configured to transmit and receive signals via the wireless access interface using predetermined narrow band carriers of different types provided by one or more cells, and the controller is configured in a combination with the transmitter and the receiver
to receive from the mobile communications network an indication listing narrowband carriers provided by one or more infrastructure equipment forming one or more cells of the mobile communications network, and an indication of the type of the narrowband carriers,
to generate a metric representing a strength or quality of signals received from one or more cells on each of the narrowband carriers, and
to select one of the cells on one of the narrowband carriers from the list of the narrowband carriers based on the type of the narrowband carrier and a value of the generated received signal metric for the signals received from the narrowband carriers, the cell on the selected narrowband carrier being used by the communications device for receiving data from the mobile communications network via the selected narrowband carrier.
