Scalable service in a wireless communication system
A method for providing scalable service in a wireless communication system is disclosed. In this method, the transmitting side device transmits base layer signals and enhancement layer signals for one scalable service to a user equipment (UE) based on a HARQ (Hybrid Automatic Repeat Request) scheme. The base layer signals can be independently used at the UE without the enhancement layer signals. On the other hand, the enhancement layer signals cannot be used at the UE without the base layer signals. The transmitting side device also retransmits the base layer signals before a retransmission of the enhancement layer signals when there are both of the base layer signals and the enhancement layer signals to be retransmitted based on the HARQ scheme.
