1. a kind of method for being transmitted in a communications system, methods described include:

  • To the multiple bits transmitted in a subframe are scrambled;

    The bit of the plurality of scrambling is modulated, to produce multiple modulation symbols;

    By the plurality of modulation symbol is mapped at least one transport layer, x (i)=[x is produced(0)(i) ... x(v-1)(i)]T

    In systemic circulation delay diversity, by y (i)=W (i) D (i) Ux (i), symbol y (i) of precoding is produced,Wherein, W (i) is the pre-coding matrix that size is P ×

    v,The size of D (i) is v ×

    v, and is the diagonal matrix for supporting systemic circulation delay diversity,U is the fixed matrix that size is v ×

    v,Wherein, P is the quantity of antennal interface, and v is the quantity of layer,Wherein, quantity v based on layer, the sub- centralized cycle of code book corresponding with P and v select W (i),Wherein,W (i)=Ck,Wherein, CkIt is the kth code word of the subset of code book, and indexes k to be set up by following formula,
