A method and system for using frequency resources in a communication system are provided. In the method and system, a total frequency band is divided into at least two frequency subbands and there is a guard interval between frequency subbands. A first frequency subband includes a TDD UL frequency subband and a TDD DL frequency subband. A second frequency subband includes an FDD UL frequency subband. A BS sets a frequency band between the TDD UL frequency subband and an FDD UL frequency subband as an additional UL frequency subband, and receives a signal from an MS in the additional UL frequency subband.

A method and an apparatus for operating a moving network in a mobile communication system are provided. A method of a Base Station (BS) for operating a Moving Network (MN) includes determining an operation mode of the MN in a cell by collecting information of the cell, and transmitting the determined operation mode to the MN. The operation mode includes at least one of an Operation ON mode in which the MN maintains links to Mobile Stations (MSs) in a service coverage area of the MN, and an Operation OFF mode in which the MN turns off the links to the MSs in the service coverage area of the MN.

A method for controlling interference in a Near Field Communication (NFC) network including a plurality of connections for direct communication between terminals is provided. The method includes receiving a signal transmitted by a first terminal through a first connection for direct communication with the first terminal, and measuring received power for the signal, measuring received power for each of interference signals upon receiving the interference signals caused by communication through connections other than the first connection among the plurality of connections, calculating a first Signal-to-Interference Ratio (SIR) using the received power for the signal and the received power for each of interference signals, and determining to one of maintain and release setup for each of the connections other than the first connection, if the first SIR is less than a threshold.
摘要:
An apparatus and method for operating a hierarchical cell in a wireless communication system are provided. A femto BS transitions into a sleep mode if there is no accessed MS for a predefined time. The femto BS transmits a FEMTO-ADV message in the sleep mode to notify of the presence of the femto BS. The femto BS releases the sleep mode upon receiving a MOB-FEMTO-AWAKE-REQ message from an MS receiving the FEMTO-ADV message. Thereafter, the femto BS communicates with the MS.
摘要:
A method and system for determining a communication mode in a communication system are provided. The system and method include determining whether a first MS and a second MS are located within a preset area where P2P communications are available, estimating a first expected performance that can be achieved when the first and second MSs operate in a cellular communication mode, estimating a second expected performance that can be achieved when the first and second MSs operate in a P2P communication mode if the first and second MSs are located within the predetermined area, and selecting one of the cellular communication mode and the P2P communication mode as a communication mode between the first and second MSs by comparing the first expected performance with the second expected performance.
摘要:
A method for transmitting and receiving data in a communication system. The method generates a frame for mapping each of multiple communication service modes of a base station providing the multiple communication service modes to a user terminal, in units of subframes each having a time interval and a frequency band. The method includes estimating a communication service mode supporting an optimal service among the multiple communication service modes provided by the base station supporting the multiple communication service modes, and sending to the base station a random access message for access to the base station over a shared channel.
摘要:
A method and system for selecting an RS in an MS in a communication system are provided, in which the MS measures channel qualities between the MS and at least two RSs, and selects an RS for relaying signals between the MS and a BS from among the at least two RSs according to the channel quality measurements.
