Patent ID: 8837622

Claim:
A method for transmitting in a communication system, the method comprising: generating a plurality of modulation symbols; and generating precoded symbols y(i) based on y(i)=W(i)·D(i)·U·x(i), where x(i)=[x (0) (i) . . . x (ν-1) (i)] T is a mapping of the plurality of modulation symbols onto at least one transmission layer, W(i) is of size P×ν, D(i) is of size ν×ν and is a diagonal matrix for support of large cyclic delay diversity, U is of size ν×ν, P is a number of antenna ports, ν is a number of layers, and wherein W(i) can be cyclically selected in a subset of a codebook corresponding to P and ν based on the number of layers ν.
