    Abstract: Methods and apparatuses are provided for transmitting feedback information in a communication system supporting multiple transmission methods with multi antenna transmission. Information for a default Multiple Input Multiple Output (MIMO) mode is received. It is determined whether the default MIMO mode is a Single-User MIMO mode or a Multi-User MIMO mode based on the information for the default MIMO mode. First Channel Quality Indicator (CQI) feedback information is calculated for one of the Single-User MIMO mode and the Multi-User MIMO mode determined as the default MIMO mode. The first CQI feedback information and DELTA CQI feedback information, which is a differential value between the first CQI feedback information and second CQI feedback information for a non-default MIMO mode, are transmitted.

  • Publication number: 20150312928
    Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

    Abstract: Disclosed is a sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. The sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. In this environment, the sounding reference signal is transmitted through an antenna pattern through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead.
