<p>A method is disclosed for guaranteeing the time alignment between the common physical channels (7a, 7b) conveying the same MBMS data to a same user (5) from multiple cells (2a, 2b) controlled by different Node Bs. The method includes periodically monitoring (21) the timing difference between said common channels and, upon detection of the attainment of a critical value of said difference (23), sending (24) to one of the Node Bs a reconfiguration message for correcting the frame and/or chip offsets on the channels (7a, 7b) which is in advance, without tearing down the channel itself.</p> |
