METHOD AND APPARATUS FOR HANDLING PACKET DUPLICATION BASED ON CONGESTION LEVEL OF FREQUENCY IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for handling packet duplication based on congestion level of frequency in a wireless communication system is provided. A wireless device configures at least two lower entities associated with an upper entity. A wireless device activates packet duplication in the upper entity for multiple frequencies. A wireless device submits a data unit to at least one lower entity among the at least two lower entities based on a congestion level of at least one frequency among the multiple frequencies. A wireless device performs transmission of the data unit.
