1. A terminal device for use with a wireless telecommunications system, the terminal device comprising:
circuitry configured to:
select a first relay node from a plurality of relay nodes of the telecommunications system;
exchange signals with a base station of the telecommunications system via the first relay node, the signals including a signal indicating a reselection threshold value that is a threshold for signal quality of a relay node and is a fixed dB set by the base station;
compare a first signal characteristic with the reselection threshold value, the first signal characteristic associated with the first relay node;
in a case that the first signal characteristic is greater than the reselection threshold value, exchange signals with the base station via the first relay node; and
in a case that the first signal characteristic is less than the reselection threshold value,
select a second relay node from the plurality of relay nodes having a second signal characteristic which is greater than the first signal characteristic, and
exchange the signals with the base station via the second relay node.
