    摘要： A method of transmitting broadcast information in a wireless communication system includes transmitting broadcast information and receiving an ACK (Acknowledgement)/NACK (Not-Acknowledgement) signal on an uplink channel from at least one mobile station in a cell, the ACK/NACK signal indicating whether the broadcast information is successfully received or not. A base station can know whether mobile stations successfully receive broadcast information or not and perform various operations to improve a reception rate of the broadcast information based on the result.

    摘要： A mode adaptation method for performing mode switching between a single-user MIMO (SU-MIMO) mode and a multi-user MIMO (MU-MIMO) mode includes reporting, by a base station, a MIMO feedback mode to a mobile station, receiving a feedback information determined on the basis of the MIMO feedback mode from the mobile station; and determining a MIMO feedback mode based on the feedback information. The MIMO feedback mode indicates whether it is single-user MIMO or multi-user MIMO and includes a number of mobile stations (MSs) transferred at one time. As a result, the method maximizes a system throughput simultaneously while effectively reducing an amount of feedback information.

    摘要翻译： 用于在单用户MIMO（SU-MIMO）模式和多用户MIMO（MU-MIMO）模式之间执行模式切换的模式适配方法包括由基站向移动台报告MIMO反馈模式，接收 基于来自移动台的MIMO反馈模式确定的反馈信息; 以及基于所述反馈信息确定MIMO反馈模式。 MIMO反馈模式指示它是单用户MIMO还是多用户MIMO，并且包括一次转移的多个移动台（MS）。 因此，该方法可以同时最大化系统吞吐量，同时有效减少反馈信息的数量。
