    摘要： The present description relates to a wireless communication system, and more particularly, to a method and apparatus for uplink multiple input multiple output (MIMO) transmission. A method for performing an uplink MIMO transmission according to one embodiment of the present invention comprises the following steps: transmitting, from a first subframe, a first data block and a second data block through a first HARQ process and a second HARQ process, respectively; receiving, at a second subframe, uplink scheduling control information on the first data block and control information which indicates inactivation of the second data block; setting HARQ feedback information on the second data block to an ACK state; and performing retransmission of the first data block from a third subframe on the basis of the uplink scheduling control information on the first data block. Retransmission of the second data block may not be performed until uplink scheduling control information on the second data block is received.

    摘要： A method of transmitting a data frame by a transmitter in a WLAN system is provided. The method includes generating a data block including at least one data units respectively transmitted through at least one or more spatial streams to at least one receiver, transmitting first control information to the at least one receiver, transmitting second control information to each receiver, and transmitting the data block to the at least one receiver. The first control information includes a length indicator for the data block, a MIMO indicator indicating whether the data block is for SU-MIMO or MU-MIMO, and a spatial stream indication field including information about the number of the spatial streams. The second control information includes a FEC coding field indicating an encoding scheme applied to the data unit and an MCS field indicating an MCS applied to the data unit.

    摘要： A method for communicating data based on an unlicensed band in a wireless communication system comprising a first type network entity and a second type network entity which is different. The first type network entity comprises a cellular base station and the second type network entity comprises a Femto-cell base station. In the method, a cellular base station identifies at least one Femto-cell base station incurring interference and instructs the identified base station to operate on an unlicensed band. The technical features can be used to improve the performance of the wireless network, and/or to reduce the effect of interference.
