摘要:
An apparatus and a method for a cluster-based power control at a macro base station in a wireless communication system are provided. The method includes broadcasting an interference allowance value determined based on a predefined aggregate interference to a femto cell, updating the interference allowance value with consideration of a channel activity for each femto cell group on a cluster basis, and when detecting a change in an aggregate interference generated due to femto cell power allocation, repeating determination of an interference allowance value so that a Quality of Service (QoS) of a macro cell user is met, and broadcasting the interference allowance value to a femto cell.
摘要:
An apparatus and a method for transmitting and receiving control information in a Multiple Input Multiple Output (MIMO) system are provided. A method of a base station for transmitting control information to a terminal in the MIMO system includes transmitting first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, to the terminal over a control channel of a subframe, and transmitting second control information for the MU-MIMO mode to the terminal over a data channel of the subframe.
摘要:
A method and apparatus for transmitting and receiving data in a multi-carrier mobile communication system are provided, in which a Mobile Station (MS) reports to a Base Station (BS) a number of Carrier Components (CCs) over which the MS can simultaneously receive data, receives from the BS monitoring CC set information indicating as many monitoring CCs as the reported number of CCs or fewer monitoring CCs than the reported number of CCs, and receives data based on the monitoring CCs indicated by the monitoring CC set information from the BS.
摘要:
A method and apparatus for preventing unauthorized use of a mobile terminal are provided, in which an execution code processor decrypts an Mobile Phone Certificate (MPC) using an MPC decryption code stored in it, when the mobile terminal is booted, an MPC processor compares a pre-stored MPC decryption execution code with the MPC decryption execution code, compares a pre-stored MPC encryption key with an MPC encryption key stored in the execution code processor. When the MPC decryption execution codes are identical, sets data required for an initial operation of the mobile terminal using an MPC management execution code included in a pre-stored MPC. When the MPC encryption keys are identical, decrypts Secured Code (SCode) blocks for execution of an application program, after executing the MPC management execution code. The execution code processor performs an operation program of the mobile terminal using the MPC management execution code and the decrypted SCode blocks.
