Patent ID: 7751403

Claim:
A method for combining broadcast data packets from a plurality of cells in a user equipment (UE), the method comprising the steps of: receiving a broadcast data packet supporting selective combining from the plurality of cells, respectively; if a sequence number of the received broadcast data packet does not fall within a reception window, storing the broadcast data packet in a buffer and updating the reception window based on the sequence number; if the sequence number of the received broadcast data packet falls within the reception window, determining if 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 foremost sequence number among sequence numbers of the broadcast data packets received, and a predetermined window size that is determined based on a maximum error range for reception points of broadcast data packets having a same sequence number, transmitted from different cells.
