1. A communication device comprising:
- a state control unit which can operate the communication device in at least the following three useful data transmission states;
a first useful data transmission state of a data link layer, in which a useful data communication link with first communication resources is allocated to the communication device,a second useful data transmission state of the data link layer, in which a useful data communication link with the first communication resources is allocated to the communication device, anda third useful data transmission state of the data link layer, in which a useful data communication link with second communication resources is allocated to the communication device, the second communication resources being fewer than the first communication resources; and
a state transition control unit which can perform at least the following state transitions;
a state change from the first useful data transmission state to the second useful data transmission state when a first state transition criterion has been met,a state change from the second useful data transmission state to the third useful data transmission state when a second state transition criterion has been met,a state change from the third useful data transmission state to the first useful data transmission state when a third state transition criterion has been met, anda state change from the second useful data transmission state to the first useful data transmission state when a fourth state transition criterion has been met.

Abstract
The communication device has three useful data transmission states, where the communication device in the first and in the second state has associated first communication resources and in the third state has associated second communication resources, with the second communication resources being fewer than the first communication resources. Provision is made for there to be state changes from the first state to the second state, from the second state to the third state, from the third state to the first state and from the second state to the first state.

31. A method for operating a communication device, comprising:
-
operating the communication device in a first useful data transmission state of a data link layer, in which a useful data communication link with first communication resources is allocated to the communication device; performing a state change from the first useful data transmission state to a second useful data transmission state of the data link layer when a first state transition criterion has been met, wherein in the second useful data transmission state a useful data communication link with the first communication resources is allocated to the communication device; performing a state change from the second useful data transmission state to a third useful data transmission state of the data link layer when a second state transition criterion has been met, wherein in the third useful data transmission state a useful data communication link with second communication resources is allocated to the communication device, the second communication resources being fewer than the first communication resources; performing a state change from the third useful data transmission state to the first useful data transmission state when a third state transition criterion has been met; and performing a state change from the second useful data transmission state to the first useful data transmission state when a fourth state transition criterion has been met.
