Abstract:
1. An apparatus, comprising: a first cellular transmitter configured to operate with at least one carrier frequency, and a first cellular receiver, wherein the first cellular transmitter and the first cellular receiver are configured, when the apparatus is in a full-duplex mode, to transmit and receive at the same time and configured, when the apparatus is in a half-duplex mode, to transmit and receive at different times and not at the same time; a signalling control configured to control the first cellular transmitter to transmit a capability information message to a cellular telecommunications network using a radio frequency signal, the capability information message comprising information identifying to the cellular telecommunications network whether full-duplex mode operation or half-duplex mode operation of the apparatus is available for the at least one carrier frequency; and a switching control configured to change the mode of operation of the apparatus, from operating in the full-duplex mode to operating in the half-duplex mode or from operating in the half-duplex mode to operating in the full-duplex mode in response to at least one trigger condition, wherein the at least one trigger condition comprises receiving a signal from the cellular telecommunications network; and wherein the switching control is responsive to interference detected at the first cellular receiver, and a change in operational mode to half-duplex mode occurs when the detected interference exceeds a threshold.
