A method according to a first example embodiment of the present disclosure comprises establishing a measurement of radio conditions associated with a first communications path between the communications device and the infrastructure equipment of the first type, determining that the first communications path is not appropriate for use by the communications device, transmitting a failure message from the communications device to one of the infrastructure equipment of the second type via a second communications path, the failure message providing information regarding the determination that the first communications path is not appropriate for use by the communications device, receiving at the communications device a signal comprising a reconfiguration message from the one of the infrastructure equipment of the second type via the second communications path, and establishing, using the reconfiguration message, signals to be transmitted by the communications device and signals to be received by the communications device. The determining that the first communications path is not appropriate for use by the communications device comprises detecting, from the measurement of radio conditions, radio link failure on the first communications path. A method according to a second example embodiment of the present disclosure comprising establishing a first measurement of radio conditions associated with a first communications path between the communications device and the infrastructure equipment of the first type, the first measurement of radio conditions comprising a quality of the first communications path, determining that the quality of the first communications path is below a first predetermined threshold, initiating a timer, the timer being configured to expire after a predetermined amount of time, establishing a second measurement of radio conditions associated with a second communications path between the communications device and one of the infrastructure equipment of the second type, the second measurement of radio conditions comprising a quality of the second communications path, determining that the quality of the second communications path is below a second predetermined threshold, terminating the timer before the predetermined amount of time has elapsed, receiving at the communications device a signal comprising a re-establishment command, and establishing that, using the re-establishment command, the communications device should transmit signals to and receive signals from a second infrastructure equipment of the first type via a third communications path.

Abstract: A method of controlling communications within a wireless communications network is provided. The communications network comprises a plurality of infrastructure equipment each being configured to communicate with one or more others of the infrastructure equipment via a backhaul communications link, one or more of the infrastructure equipment each being configured to communicate with one or more communications devices via a wireless access interface. The method comprises receiving, at a first of the infrastructure equipment acting as a donor node connected to a core network part of the wireless communications network, from a second of the infrastructure equipment, information relating to each of a plurality of different communications paths from the second infrastructure equipment to the first infrastructure equipment via one or more others of the infrastructure equipment acting as relay nodes, determining, based on the received information relating to the plurality of different communications paths, that either at least a part of a new communications path exists between the first of the infrastructure equipment and the second of the infrastructure equipment or at least a part of a previously known communications path no longer exists between the first of the infrastructure equipment and the second of the infrastructure equipment, and updating a communications path list by either adding the at least the part of the new communications path or deleting the at least the part of the previously known communications path that no longer exists.
