Abstract:
PURPOSE: A communication system having an optimum network access structure is provided to reduce the number of handover in order to increase the utilization ratio of a radio resource. CONSTITUTION: A first processing module performs a signal process of an RRC(Radio Resource Control) layer, a MAC(Media Access Control) layer, and PHY layer. A switch connects a first processing module and a plurality of wireless connection devices that include a second processing module(720) according to the integration of wireless connection devices. Each second processing module transmits and receives an RF(Radio Frequency) signal by using one antenna.

PURPOSE: A method and a device for cell reselection of mobile terminal are provided to reflect a priority setting of proceeded signal strength after scaling signal strength of femto cell to perform cell reselection of the femto cell. CONSTITUTION: If a signal strength of reference macro cell BS(Base Station) is bigger than a signal strength of femto cell BS, a terminal performs scaling signal strength of the femto cell BS(S355). The terminal determines a priority about cell selection according to a signal strength processed by the femto cell station and a signal strength of the standard macro cell base station(S325). The terminal selects a BS which is highest priority as a cell reselection target(S340).

Abstract:
PURPOSE: A cooperation terminal selection method and apparatus thereof are provided to measure link states of a cooperation terminal by broadcasting RTS(Ready To Send) message and by establishing a timer based on channel values. CONSTITUTION: A reception unit(810) receives help messages from a cooperation request terminal. The help message includes identification information of the cooperation request terminal, target RSS(Received Signal Strength), and a pilot signals. A timer establishment unit(820) establishes a timer based on the RSS of a target terminal, RSS change rates of the target terminal, and the target RSS. A transmission unit(830) transmits an RTS message when the timer is completed. A control unit(840) receives a CTS(Clear To Send) message from the cooperation request terminal.

Abstract:
PURPOSE: A target terminal and cooperation communication method of a cooperation terminal is provided to improve the quality of reception data by using cooperation between terminals in cell environment. CONSTITUTION: A target terminal requests cooperation to one or more neighbor terminals(410). The target terminal acquires information for transmission power requested by information for a cooperation method(420). The target terminal selects a cooperation terminal from one or more neighbor terminals based on the transmission power(430). The target terminal cooperatively communicate with the cooperation terminal according to a cooperation method(440).
Abstract:
PURPOSE: A macro base station, small base station, and communication method of a terminal are provided to determine the handover of a target terminal having low SINR(Signal to Interference plus Noise Ratio) through the uplink interference information of a base station. CONSTITUTION: Uplink interference information of a small base station is received from a specific small base station within a macro cell(320). The SINR of the specific small base station is calculated(330). It is determined whether a target terminal performs handover of the specific small base station(350).
Abstract:
PURPOSE: A method for communication system for performing multi cell common operation is provided to transmit uplink feedback information to all base stations in all terminals in a common operation set. CONSTITUTION: A central control unit sets a common operating set(620). The central control device allocates intrinsic UL radio resources of each terminal in previously allocated common radio resources for common operation set to enable each terminal in the common operation set to transmit corresponding UL feedback information to a base station(630). The central control device collects the UL feedback information of each terminal from the base station(650).
