Abstract: A terminal device and a method of operating a terminal device in a wireless communication network. The method comprises establishing, by the terminal device, a first radio connection with a first network access node for transmission of data via a first bearer and a second radio connection with the first network access node for transmission of data via a second bearer. Based on a difference between quality of service for the data transmission via the first bearer and the second bearer, a third radio connection is established between the terminal device and a second network access node for transmission of the data via the first bearer; and the third radio connection is established between the terminal device and the second network access node, a fourth radio connection is established between the terminal device and the second network access node for transmission of the data via the second bearer.

Abstract: A method of controlling communications within a wireless communications network is provided. The method comprises determining, by a first of the infrastructure equipment acting as a donor node connected to a core network part of the wireless communications network, that a plurality of different communications paths exist from a second infrastructure equipment to the first infrastructure equipment via one or more other infrastructure equipment acting as relay nodes, transmitting, by the first infrastructure equipment, an indication at least part of each of one or more of the plurality of different communications paths to the second infrastructure equipment, and selecting, by the second infrastructure equipment based on the indication received from the first infrastructure equipment, at least one of the plurality of different communications paths for communicating with the first infrastructure equipment.
