Abstract: PURPOSE: A control channel scheduling method and an apparatus thereof in an SDMA(Spatial Division Multiple Access) mobile communication system are provided to determine the combination of the number of CCEs as a scheduling target and to allocate a resource which terminals request. CONSTITUTION: A sub-group member selecting unit(615) performs sub-group operations. A CCE(Control Channel Element) number calculating unit(620) calculates the number of CCEs through a sub-group process. A control unit(605) determines the number of the calculated CCE as a scheduling target. The control unit allocates a resource which terminals request. [Reference numerals] (605) Control unit; (610) Group member selecting unit; (615) Sub-group member selecting unit; (620) CCE(Control Channel Element) number calculating unit

Abstract: PURPOSE: A method for transmitting and receiving channel related information in a multicast communication system is provided to maintain low overhead of channel state information within a multicast group. CONSTITUTION: A transmitter allocates shared feedback resources to a multicast group(200). The transmitter transmits the shared feedback resources to a receiver through a control channel(205). The transmitter obtains sequences within information(210,220). The transmitter transmits data through an MCS(Modulation and Coding Scheme) level that satisfies CQI(Channel Quality Indicator)(225).
Abstract translation: 目的：提供一种在组播通信系统中发送和接收信道相关信息的方法，以保持组播组内信道状态信息的低开销。 构成：发射机将共享的反馈资源分配给组播组（200）。 发射机通过控制信道（205）将共享的反馈资源发射到接收机。 发射机获取信息内的序列（210,220）。 发射机通过满足CQI（信道质量指示符）（225）的MCS（调制和编码方案）级别发送数据。
