    摘要： A method for efficiently transmitting and receiving feedback information is disclosed. A cluster size as a unit for computing the feedback information and a reporting period of the feedback information are not uniformly determined by a base station. Information about a downlink channel status of each user equipment is reported, the cluster size and feedback period for computing and reporting the feedback information are determined using the information about the downlink channel status of each user equipment, and the feedback information is transmitted/received, thereby improving system capability.

    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.
