A method and apparatus for controlling Discontinuous Reception (DRX) by a User Equipment (UE) in a wireless communication system is provided. The UE receives a DRX configuration parameter from an evolved Node B (eNB), and determines whether to start an on-duration timer based on the DRX configuration parameter, after a change in DRX cycle is completed in a subframe, thereby preventing system performance degradation caused by transmission mismatch between the eNB and the UE.

A method and apparatus for measuring a use of radio resources in a wireless communication system are provided. The method includes allocating radio resources to a plurality of transport blocks, and, if at least one transport block among the plurality of transport blocks overlaps at least one other transport block in terms of the radio resources, a use of the radio resources is measured by calculating a sum of a value determined by dividing the number of radio resources allocated to each of the plurality of transport blocks by the number of radio resources which are used by the at least one other transport block in a duplicate manner.

A method and apparatus for uplink scheduling in a communication system are provided. The method includes determining whether a User Equipment (UE) is included in an uplink scheduling list, a buffer length of the UE is estimated, if the UE is included in the uplink scheduling list, it is determined whether a Buffer State Report (BSR) indicating the buffer length of the UE has been received from the UE, if the estimated buffer length is 0, and the UE is transitioned to a non-zero BSR reception state and maintained in the uplink scheduling list, if the BSR has not been received from the UE. The non-zero BSR reception state is a state in which a zero BSR indicating the buffer length of the UE is 0 has not been received.

An apparatus and method for automatically searching for a low-power Base Station (BS) supporting access of a registered user in a mobile communication system includes a method of performing automatic search on a Closed Subscriber Group (CSG) cell by a User Equipment (UE). The method includes determining by the UE whether automatic search needs to be performed on the CSG cell. The method also includes, if it is determined that automatic search does not need to be performed on the CSG cell, turning off by the UE a CSG cell automatic search function of the UE by emptying a first white list including CSG Identifiers of accessible CSG cells.

A method and an apparatus for transmitting and receiving System Information (SI) of a femto base station in a wireless communication system are provided. In the method, an SI transmission point is determined using unique identification information of a femto base station itself and unique identification information of a macro base station with which the femto base station is associated. Each of user equipment and the macro base station generate a measurement gap pattern representing an SI reception point using the unique identification information of the femto base station and the unique identification information of the macro base station. SI is received from the femto base station according to the generated measurement gap pattern.

A method and apparatus estimate a delay of buffer data of a User Equipment (UE) in a mobile communication system. A message comprising the size of buffer data is received from a UE. The size of the buffer data of the UE is distributed into a plurality of groups based on a time point of receiving the message comprising the size of the buffer data of the UE. A delay for each of the plurality of groups is estimated using a time interval of execution of delay estimation for the buffer data of the UE.

A method and an apparatus for controlling transmitter power of a femto base station in a broadband wireless communication system are provided. In the method, a femto base station receives a signal having an intensity of a threshold or more from UE and transmits a message reporting power-on of a transmitter to a femto base station controller. The UE transmits a message reporting downlink signal measurement results of femto base stations to the femto base station controller via a macro base station. The femto base station controller determines a femto base station which becomes a handover target of the UE using report messages of the femto base stations and the UE. The femto base station controller transmits a handover procedure start message to the macro base station and the determined femto base station.

A method is provided for transmitting inter-cell interference information by a serving Evolved Node B (ENB) in a communication system. The method includes, if a specific resource is allocated to a User Equipment (UE) located in a service region of the serving ENB, checking a location of the UE in the service region; setting a High Interference Sensitivity (HIS) of the UE depending on the result of the checking; determining a location of the UE in an adjacent cell of the service region; setting a High Interference Transmission (HIT) of the UE depending on the determination result; and transmitting a High Interference Indicator (HII) for the specific resource, which includes the HIS and the HIT, to the adjacent cell.

An apparatus and method provide an effective handover of a User Equipment (UE) in a wireless communication system from a macro evolved Node-B (eNB) to a relay eNB). In a method of supporting a handover of a User Equipment (UE) by a macro evolved Node-B (eNB) in a wireless communication system, a handover of the UE to a relay eNB is determined. A handover request and RRC connection setup message is transmitted to the relay eNB by integrating a handover request message for requesting a handover of the UE and an RRC connection setup message for requesting RRC connection setup between the macro eNB and the relay eNB. A handover request response and RRC connection setup response message are received from the relay eNB by integrating a handover request response message and an RRC connection setup response message.
