摘要： A method for transmitting and receiving a control channel message in a mobile communication system using multiple antennas is provided. A base station determines whether a common pilot is used or a dedicated pilot is used. It also determines whether a corresponding Multiple Input Multiple Output (MIMO) mode is a Multi-CodeWord (MCW) MIMO mode or a Single CodeWord (SCW) MIMO mode, and determines whether knockdown precoding is used or ready-made precoding is used. The base station generates a control channel message field including a pilot pattern and a precoding type according to the determination results, and transmits the generated control channel message to the terminal. The terminal receives a control channel message transmitted from a base station. The terminal analyzes the control channel message field, and determines a data reception method according to the analysis result.

摘要： A Channel Quality Indicator (CQI) expression and feedback method prevents an excessive increase in the CQI feedback overhead while supporting both Single-User MIMO and Multi-User MIMO operations. When a default MIMO operation is set to Single-User MIMO or Multi-User MIMO, an access network can receive MIMO CQI feedback optimized for the corresponding MIMO operation. However, when a scheduler has selected an alterative MIMO operation other than the default MIMO operation, the access network calculates a CQI necessary for the alternative MIMO operation based on the default MIMO CQI feedback for the default MIMO operation and the DELTA CQI feedback for the alterative MIMO operation. In this manner, the invention enables the best operation in the default MIMO operation by providing a correct CQI, and enables the second best operation in the alternative MIMO operation.
摘要翻译：信道质量指示符（CQI）表达和反馈方法防止了CQI反馈开销的过度增加，同时支持单用户MIMO和多用户MIMO操作。当将默认MIMO操作设置为单用户MIMO或多用户MIMO时，接入网络可以接收针对相应MIMO操作优化的MIMO CQI反馈。然而，当调度器选择除默认MIMO操作之外的替代MIMO操作时，接入网基于用于默认MIMO操作的默认MIMO CQI反馈和用于替代的MIMO操作的DELTA CQI反馈来计算替代MIMO操作所需的CQI MIMO操作。以这种方式，通过提供正确的CQI，本发明能够在默认的MIMO操作中实现最佳的操作，并且使得在替代的MIMO操作中能够实现第二最佳的操作。
