Abstract: According to the invention, a mobile station and a base station communicate with each other using a frame including one or more downlink subframes and one or more uplink subframes. The base station starts the transmission of a data burst in the subframe corresponding to a downlink subframe index. The mobile station transmits feedback for the data burst in the subframe corresponding to an uplink subframe index. In the event the frame operates in accordance with a time division duplex scheme, the uplink subframe index is determined using at least the downlink subframe index and a parameter value.

Abstract: In the present invention, a mobile station receives information on a multiple-input multiple-output (MIMO) feedback mode bitmap and a feedback period. The mobile station estimates channel information, which pertains to at least one of the MIMO feedback modes indicated by a MIMO feedback mode bitmap. The mobile station creates a MIMO feedback mode bitmap and a MIMO feedback, which contains at least one of the MIMO feedback modes indicated by a MIMO feedback mode bitmap. The mobile station transmits the MIMO feedback to a base station upon the arrival of a feedback period.

Abstract: PURPOSE: A method for detecting signal, a device for detecting signal and a receiving device are provided to execute signal detection in a low complexity. CONSTITUTION: Candidate vector generating units(261,262) decide a first candidate vector about a first layer of the transmission signal group in consideration of all constellation points. The candidate vector generating units decide a second candidate vector about the second layer of the transmission signal group in consideration of all constellation points. The candidate vector generating units generates a final candidate vector including the first candidate vector and the second candidate vector. A soft decision value generating unit(270) produces the soft decision value using the final candidate vector.
