Abstract:
1. A method for performing duplicate avoidance of broadcast data packets from a plurality of cells in a User Equipment (UE), the method comprising the steps of: receiving a broadcast data packet from each of the plurality of cells; storing, if a sequence number of the received broadcast data packet does not fall within a reception window, the broadcast data packet in a buffer and updating the reception window based on the sequence number; determining, if the sequence number of the received broadcast data packet falls within the reception window, whether a broadcast data packet having the sequence number has previously been stored in the buffer; discarding the broadcast data packet, if the broadcast data packet has previously been stored in the buffer; and storing the broadcast data packet in the buffer, if the broadcast data packet has not previously been stored in the buffer, wherein the reception window is determined based on a highest sequence number among sequence numbers of the broadcast data packets received, and a predetermined window size.
