Abstract

A method of handling transmission configuration of a communication device in a wireless communication system is disclosed. The method is utilized in the communication device, and comprises determining traffic information of a plurality of packets which are transmitted between the communication device and a network of the wireless communication system according to the transmission configuration; and transmitting the traffic information to the network, for the network to configure the transmission configuration according to the traffic information.
