Abstract:
본개시는 LTE와같은 4G 통신시스템이후보다높은데이터전송률을지원하기위한 5G 또는 pre-5G 통신시스템에관련된것이다. 본발명은비면허대역을이용하는무선통신시스템에서통신을수행하는방법및 장치에대한것으로서, 본발명의실시예에따라비면허대역을이용하는무선통신시스템에서기지국이 CCA 타이밍을제어하는방법은, CCA의연속적인성공또는실패횟수를정해진임계값과비교하여 CCA 타이밍의변경여부를결정하는과정과, 상기 CCA 타이밍의변경이결정된경우, 상기 CCA 타이밍을랜덤화하는과정을포함한다.
Abstract:
PURPOSE: Device and method thereof for transceiving a reference signal in a wireless communication system are provided to offer a reference signal appropriate for cluster configuration. CONSTITUTION: A control unit (1340) determines a cluster-specific reference signal configuration according to a cluster configuration. Each of plurality of transceivers (1310-1-1310-N) transmits information on the cluster-specific reference signal configuration. The each of plurality of transceivers transmits cluster-specific reference signals according to the cluster-specific reference signal configuration. A cluster means a service coverage unit configured by combination of at least one transceiver.

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.
