Patent ID: 8345657

Claim:
A method of processing to-be-transmitted data packets based on a transmission time interval in a sending device of a wireless communication network, the method comprising: according to said transmission time interval, determining a transmission queue of component data packets corresponding to the transmission time interval based on a to-be-transmitted data packet; generating a sub-header for each component data packet in said transmission queue in accordance with the following information in the component data packet: an original data packet ID that indicates the original data packet which the component data packet belongs to; a segmentation processing ID comprising the number of times that segmentation has occurred with respect to said original data packet in order to obtain said component data packet, and the data segment which said component data packet belongs to after each segmentation; a data amount ID that indicates the data amount of the data portion of said component data packet; generating a transmitted data packet based on each of said generated sub-headers and data portions of the respective component data packets in said transmission queue, whose header portion contains at least one component number indicating information for indicating the number of component data packets contained in said transmitted data packet.
