    摘要: The present invention relates to a wireless communication system, and more particularly, to a method of transmitting feedback, by which a signaling overhead can be efficiently reduced. In receiving a group feedback by a transmitting end in a wireless communication system, the present invention includes transmitting at least one data unit to a receiving end during a prescribed time interval and receiving a group feedback indicating a presence or non-presence of error for the overall at least one data unit from the receiving end. Accordingly, a transmitting/receiving end of a communication system transceives a group feedback for multiple feedbacks indicating an error presence or non-presence of overall data received in TTI, thereby reducing a signaling overhead.

    摘要: A closed-loop antenna switching method, a reference signal allocating method, and a feedback signal transmitting method for the same are disclosed. Namely, by transmitting a reference signal via the plurality of transmitting antennas via the antenna switching for reference signal transmission for each prescribed multiple period of an antenna selection period, efficient antenna index information can be fed back. By setting an antenna switching period to a prescribed multiple of an antenna selection period, it is able to prevent power loss and data decoding performance degradation. And, the present invention includes transmitting a sounding reference signal (SRS) for each band selection period via at least one of the plurality of transmitting antennas and transmitting at least one data demodulation reference signal (DMRS) between the band selection periods via an antenna for not transmitting data by reference signal transmission antenna switching.
