Abstract: 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.

Abstract: Disclosed is a method for performing contention-based transmission by a user equipment in a wireless communication system. Specifically, the method comprises the steps of: calculating a channel congestion for contention-based transmission within a predetermined time window; and performing contention-based transmission to an eNode B, using an allocated resource on the basis of the calculated channel congestion, wherein: the channel congestion is a ratio of a size of resources used for contention-based transmission at a unit time point to a size of a resource pool for the contention-based transmission at the relevant unit time point, and is calculated at every unit time point within the time window; and the size of the resource pool is independently configured at every unit time point.

Abstract: A method and device for transmitting a transport block in a wireless communication system is provided. Particularly, a terminal receives, from a base station, information on the number of subcarriers in a partial band included in an allocated carrier. The terminal distributes a soft buffer possessed by the terminal in proportion to the number of subcarriers in the partial band. The terminal determines a transport block size for each partial band according to the size of the distributed soft buffer. The terminal transmits, to the base station, the transport block within the transport block size.

Abstract: A method for providing scalable service in a wireless communication system is disclosed. In this method, the transmitting side device performs initial transmission of base layer signals to a user equipment (UE) based on a HARQ (Hybrid Automatic Repeat Request) scheme, and performs transmission of enhancement layer signals to the UE after finishing the initial transmission of the base layer signals. The base layer signals and the enhancement layer signals are for one scalable service. The base layer signals can be independently used at the UE without the enhancement layer signals, while the enhancement layer signals cannot be used at the UE without the base layer signals. The transmitting side device further performs retransmission of the base layer signals determined to be retransmitted based on the HARQ scheme while performing the initial transmission of the enhancement layer signals.
