7. A terminal capable of communicating with a base station, wherein said terminal comprises:
at least one memory comprising at least two storage areas organised in a stack, and at least one processing unit configured to:
store, in one of said storage areas, at least one state representative of a transmission, by the base station on a transmission channel, of at least one current data packet and control information associated with said current data packet, called a transmission current, said storage area being identified by a storage area indicator borne by said control information associated with said current data packet, and
transmit, to said base station, all states stored in said storage areas, in response to the transmission channel between said terminal and said base station being considered as idle,
store, in one of said storage areas, a state representative of a transmission, by the base station, of at least one previous data packet and control information associated with said previous data packet, called previous transmission, said storage area in which the state of the previous transmission is stored being identified from the storage area indicator borne by said control information associated with said current data packet;
identify, from the storage area indicator borne by said control information associated with the current data packet, the storage area of the state representative of the current transmission, corresponding to a current level in said stack,
determine, from said control information associated with the current data packet, that the control information associated with a previous data packet has not been received, by detecting at least one empty storage area corresponding to a level lower than said current level in the stack,
store in said at least one empty storage area corresponding to the level lower than said current level in the stack, the state representative of a previous transmission indicating that the control information associated with a previous data packet has not been received.
