    摘要: A method of transmitting data from a user terminal to a base station using a hybrid automatic repeat request (HARQ) scheme with a plurality of redundancy versions of said data, each of the redundancy versions (RV) indicating a transmission start position of a data block in a circular buffer is disclosed. For each retransmission, the redundancy version to be used by considering the previously used redundancy version and a predetermined sequence is determined. Within one sequence, at least two redundancy versions following each other have non consecutive start positions.

    摘要: A method of transmitting a multiple input multiple output (MIMO) packet by a transmitter in a wireless local area network (WLAN) system is provided. The method includes: generating a MIMO packet including at least one spatial stream set transmitted respectively to at least one receiver, wherein each spatial stream set is encoded on the basis of one of two encoding schemes; transmitting first control information including a MIMO indicator and a first modulation and coding scheme (MCS) field, wherein the MIMO indicator indicates whether the MIMO packet is for single user (SU)-MIMO or multi user (MU)-MIMO, and the first MCS field indicates an MCS used for the MIMO packet if the MIMO packet is for SU-MIMO transmission, and indicates an encoding scheme applied for each of the spatial stream sets if the MIMO packet is for MU-MIMO transmission; and transmitting the MIMO packet to at least one receiver.

    摘要: A method for transmitting Channel Quality Indicators (CQIs) of all carrier bands in a system using a plurality of carrier bands (legacy system bands) is disclosed. In order to provide sufficient information to a scheduler, the CQIs of all the carrier bands are generated and transmitted by the same method or a predetermined number of carrier bands are selected and only the CQIs of the selected carrier bands are transmitted. Thus, it is possible to efficiently control signal resources. By simply expanding the method for transmitting the CQIs of the carrier bands, it is possible to facilitate the expansion of the system.
