摘要： An apparatus and method for automatically controlling interference in a broadband wireless communication system are provided. In the method, a BS receives an interference measurement information signal of one or more adjacent BSs. The BS analyzes the interference measurement information signal of the one or more adjacent BSs to obtain information about the average power for each frequency band used by each of the one or more adjacent BSs. The BS uses the obtained information about the average power for each frequency band of the one or more adjacent BSs to determine the average power for each frequency band to be used by the BS. The BS generates an interference measurement information signal of the BS according to the determined average power for each frequency band.

摘要： A method and apparatus for establishing a Peer-to-Peer (P2P) connection between Mobile Stations (MSs) in a wireless communication system are provided. A method of operating a transmitting MS for establishing the P2P connection between the MSs in the wireless communication system includes when a location of a receiving MS is not known, requesting a Base Station (BS) to transmit a message instructing MSs to prepare for P2P setup, and thereafter, broadcasting to neighbor MSs a message requesting P2P-related information, receiving the P2P-related information from each of the neighbor MSs, generating a list of MSs capable of P2P communication using the received P2P-related information, and establishing a P2P connection by selecting the receiving MS from the list of MSs with which P2P communication is desired. Accordingly, in an environment where the location of the receiving MS is not known, the receiving MS can be found and thus the P2P connection can be established. Therefore, subscribers of P2P communication can be easily managed by the BS.

摘要： A system and a method minimize power consumption, signalling overhead, and processing load in blind scheduling in a mobile communication system. A User Equipment (UE) detects a type of an uplink (UL) grant while it is periodically allocated the UL grant. If there is no data to transmit using the UL grant, the UE determines whether to transmit a padding Medium Access Control (MAC) Protocol Data Unit (PDU) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) using the UL grant according to the type of the UL grant.
