    摘要: A method for transmitting data in a multiple antenna system comprises the steps of: generating a transmission signal in plural antennas through the application of a precoding eight matrix to first and second antenna clusters including the plural antennas, and transmitting the transmission signal. The precoding weight matrix is a block diagonal matrix that is configured in a precoding weight corresponding to first and second antenna clusters respectively. The precoding weight of the first antenna cluster is selected according to a channel condition, and the precoding weight of the second antenna cluster is selected regardless of the channel condition but according to a rule.

    摘要: A method of transmitting feedback information in a multiple antenna system is provided. The method includes selecting at least one subband selected from a plurality of subbands according to subband preset information, the subband preset information being a preset on data processing settled for each of the plurality of subbands, and transmitting a subband index of the selected subband. Only a subband index is fed back instead of separately transmitting a precoder index or a modulation and coding scheme (MCS) level index to each UE, thereby reducing feedback overhead.

    摘要: A method of transmitting data in a multiple antenna system includes transmitting first data through a first pilot pattern zone in which pilots are arranged in a specific pilot pattern in a permutation zone having at least one tile comprising a plurality of orthogonal frequency division multiplexing (OFDM) symbols and a plurality of subcarriers, and transmitting second data through a second pilot pattern zone in which pilots are arranged in another pilot pattern different from the pilot pattern of the first pilot pattern zone in the permutation zone. Accordingly, a plurality of pilot patterns can be simultaneously used in one permutation zone, and thus waste of radio resources caused by the use of unnecessary pilots can be reduced by adaptively assigning pilots according to various channel environments and performances of user equipments.

    摘要: A method of transmitting data in a multiple antenna system includes transmitting a precoding matrix index (PMI) of a first user through a control channel for the first user, and transmitting the PMI of the first user and a PMI of a second user through a data channel for the first user. Effective data decoding is possible regardless of whether radio resources to be allocated to multiple users are partially or entirely allocated to the users.

    摘要: A method for correcting errors in a multiple antenna system based on a plurality of sub-carriers and a transmitting/receiving apparatus supporting the same are disclosed. The method includes determining a phase shift based precoding matrix phase shifted at a predetermined phase angle, initially transmitting each sub-carrier symbol to a receiver in a packet unit by using the phase shift based precoding matrix, reconstructing the phase shift based precoding matrix to reduce a spatial multiplexing rate if a negative reception acknowledgement (NACK) is received from the receiver, and retransmitting the initially transmitted sub-carrier symbol by using the reconstructed phase shift based precoding matrix or by changing the phase shift based precoding matrix using offset information fed back from the receiver or random offset information.
