摘要： A method and apparatus for allocating frequency resources for peer to peer (P2P) communication between terminals without a base station are provided. The method determines resources used for a direct communication between two terminals in a communication system. The method includes determining uplink frequency resources of a cellular communication system for use in the direct communication between the two terminals, determining a primary maximum transmission power to minimize interference caused by the direct communication on the cellular communication system and performing the direct communication between the two terminals by using the uplink frequency resources and a transmission power less than the determined primary maximum transmission power.

摘要： An apparatus and method for determining a beamforming vector in a codebook-based transmission beamforming system are provided. In a feedback method for a receiver in a codebook-based transmission beamforming system, forthcoming channel values for a forthcoming period are generated using M present and previous channel estimates. Effective channel gains for all transmission beamforming vectors included in a codebook are calculated using the forthcoming channel values. A codebook index corresponding to the maximum effective channel gains is fed back to a transmitter.

摘要： A method and apparatus for transmitting common control information by a base station in a wireless communication system are provided. The base station determines whether a first system and a second system different from the first system coexist in a wireless communication system. When the wireless communication system is a coexistence system, the base station indicates information for coexistence of the first system and the second system, position and size information of a resource allocation zone where common control information for the second system can be transmitted, and information necessary for decoding of the resource allocation zone, through a first information element in a downlink subframe where resources are occupied for the first system. The base station transmits the common control information of the second system in the resource allocation zone where the common control information can be transmitted.
