Abstract:
A method implemented in a base station used in a wireless communications system is disclosed. The method comprises having 1-layer, 2-layer, 3-layer, and 4-layer codebooks for 4 transmit antenna (4TX) transmission, each codebook including a plurality of precoding matrices, precoding data with one of the plurality of precoding matrices, and transmitting, to a user equipment, the precoded data, wherein each of the 1-layer and 2-layer codebooks comprises a first codebook and a second codebook, and wherein each precoding matrix in the first codebook comprises a first index and a second index. Other apparatuses, systems, and methods also are disclosed.

Claim (Index 35):
A base station used in a wireless communications system, the base station comprising:\n a transmitter to transmit, to a user equipment, precoded data, wherein the base station has a first 1-layer, a second 1-layer, a first 2-layer, a second 2-layer, 3-layer and 4-layer codebooks for 4 transmit antenna (4TX) transmission, each codebook including a plurality of precoding matrices, wherein the first 1-layer codebook includes a plurality of precoding matrices each of which comprises an element represented by [ 1 e j \u00d7 \u03b8 2 e j \u00d7 \u03b8 3 e j \u00d7 ( \u03b8 2 + \u03b8 3 ) ] , \u2003and wherein the first 2-layer codebook includes a plurality of precoding matrices each of which comprises an element represented by [ 1 1 e j \u00d7 \u03b8 2 e j \u00d7 \u03b8 2 e j \u00d7 \u03b8 3 - e j \u00d7 \u03b8 3 e j \u00d7 ( \u03b8 2 + \u03b8 3 ) - e j \u00d7 ( \u03b8 2 + \u03b8 3 ) ] , each of \u03b8 2  and \u03b8 3  taking a value equal to or greater than 0 but less than 2\u03c0, and\n j= \u221a{square root over (\u22121)}.
