摘要： A type 1 system and a type 2 system are classified according to whether carrier aggregation is used. A shared component carrier is used for both a type 1 terminal and a type 2 terminal, whereas a dedicated component carrier is used only for the type 2 terminal. Also, a type 2 base station transmits broadcast information by using a shared component carrier. In this instance, the broadcast information includes the shared broadcast information used for both the type 1 terminal and the type 2 terminal and the dedicated broadcast information only for the type 2 terminal. Also, the type 2 base station indicates component carriers that are used by the type 2 terminal, by using a semi-static component carrier indicator or a dynamic component carrier indicator.

摘要： Provided are a data transmission method in a communication system and a relay performing the same. The data transmission method in a communication system includes receiving, at a relay, an uplink buffer status report (BSR) of a terminal from the terminal, including the uplink BSR of the terminal received by the relay in an uplink BSR to be transmitted from the relay to a base station to generate a combined uplink BSR, and transmitting the combined uplink BSR to the base station even before the relay receives data stored in an uplink buffer of the terminal from the terminal. Accordingly, it is possible to reduce the transmission delay of the communication system including a relay.

摘要： Disclosed is a method of using relay that may continuously transmit data without time division based on superposition coding in a communication system. When transmission of a relay-supported user signal via a base station-relay link is performed, the method of using relay based on the superposition coding reuses a resource allocated to a direct-transmission user based on the superposition coding to perform the transmission. According to example embodiments, a separate resource for the base station-relay link may not be needed, and continuous relay transmission is possible without time division, thereby substantially increasing frequency efficiency and reducing a transmission delay caused by the use of the relay.
