    摘要： A method for generating a downlink signal in a downlink MIMO (Multiple Input Multiple Output) comprises the steps of: mapping at least one transport block to at least one codeword; mapping at least one layer to each codeword; classifying at least one layer mapped to each codeword into a certain number of layer groups and performing layer permutation by the layer groups; and generating an OFDM (Orthogonal Frequency-Division Multiplexing) symbol using a signal which is permutated by the layer groups. A CRC (Cyclic Redundancy Check) is attached by the layer groups.

    摘要： A resource allocation method for a Multicast and Broadcast Service (MBS) and a method for transmitting MBS data in a wireless access system are disclosed. The MBS transmission method for a multicast broadcast single frequency network (MBSFN) zone includes, constructing a resource zone by sequentially allocating predetermined symbol areas preferentially on a frequency axis, mapping predetermined MBSs provided from the MBSFN zone to the predetermined symbol areas, and transmitting a first MBS among the predetermined MBSs to mobile stations located at an edge of the MBSFN zone. The first MBS is equal to a second MBS among MBSs provided from a neighbor MBSFN zone. The first MBS and the second MBS are transmitted to the same time zone according to a time division multiplexing (TDM) method.
