    摘要: A method for transmitting data by applying a precoding matrix in an open-loop multiple input multiple output (MIMO) system is disclosed. The method comprises selecting a precoding matrix and applying the selected precoding matrix to data during initial transmission; selecting a precoding matrix and applying the selected precoding matrix to data to be retransmitted; and retransmitting the data to which the precoding matrix is applied, wherein an index of the precoding matrix applied to the data is determined based on the times of current retransmission times of the data and index of the precoding matrix applied during initial transmission of the data.

    摘要: A method for modifying a synchronous non-adaptive retransmission scheme to solve the limitation of the synchronous non-adaptive retransmission scheme is disclosed. A method for indicating not only the new data transmission but also the retransmission using a data scheduling message is disclosed. A method for determining whether there is an error in the ACK signal transmitted from a data reception end using another message to-be received later is disclosed. The retransmission method for a multi-carrier system includes: receiving a grant message including scheduling information for transmitting uplink data wherein a retransmission scheme for the uplink data is predetermined by a first retransmission scheduling, transmitting the uplink data according to the scheduling information and retransmitting the uplink data according to second retransmission scheduling by receiving the second retransmission scheduling information associated with the uplink data with retransmission request.

    摘要: The present invention relates to a wireless access system, and more particularly, to a method for controlling uplink transmission power in consideration of a transmission rank in a multi-antenna environment. A method for controlling the transmission power of an uplink data channel at a transmitting end which supports a plurality of transmission ranks according to one embodiment of the present invention, comprises the steps of: determining a first transmission power using at least one rank variable dependent on the transmission rank in a specific subframe; comparing the determined first transmission power with a second transmission power which is the preset maximum transmission power; and determining the value judged to be smaller than the result of the comparison to be the transmission power of the data channel.
