Claim 11:
12. A first access device for accessing a telecommunications network, the first access device able to manage a transmission of sequences of data symbols of predetermined duration by a terminal having a dual connectivity established with the first device for accessing a telecommunications network and with a second access device for accessing a telecommunications network, the terminal being configured to transmit, during the dual connectivity, sequences of data symbols on a first uplink channel towards the first access device and on a second uplink channel towards the second access device during disjoint time intervals, the first access device comprising a processor, the first access device configured to:
obtain an estimate of a deviation between propagation delays between the terminal and the first access device and between the terminal and the second access device; and
configure the terminal so that it introduces at least one guard interval during each transmission of at least one sequence of data symbols on the first uplink channel towards the first access device, during which no data symbol is transmitted by the terminal on the first uplink channel, the at least one guard interval being introduced by the terminal at the start of a first sequence of data symbols and/or at the end a last sequence of data symbols transmitted during the transmission on the first uplink channel, and occupying a number of symbols determined based on the estimate of the deviation between the propagation delays.
