METHOD AND APPARATUS FOR SUPPORTING FAIRNESS BETWEEN DUPLICATED PACKET AND NON-DUPLICATED PACKET IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/216679

Kind Code:

A1

Abstract:

A method and apparatus for supporting fairness between a duplicated packet and a non-duplicated packet in a wireless communication system is provided. A wireless device generates a duplicated packet of an original packet, receives a parameter, calculates an amount of the duplicated packet based on the parameter, and determines whether to drop the duplicated packet based on the calculated amount of the duplicated packet. Whether to drop the duplicated packet based on the amount of the duplicated packet may be determined based on a maximum limit of packets, which comprises a channel occupancy ratio (CR) limit or a maximum amount of packets to be transmitted.
