Abstract: Precoding for multiple transmission streams in multiple antenna systems. Disclosed herein is a general method that transmits signal from multiple antennas using a one/two dimensional precoder. This precoder is fixed in a given resource block (RB) or slot, which is composed of P subcarriers and Q OFDM symbols (where the values for P and Q are greater than or equal to 1). The precoder in each resource block may take same or different values, which span the two dimensional time-frequency grid. The precoder is chosen as a function of either logical frequency index or physical frequency index of the RB.

Abstract translation: 在多个天线系统中的多个传输流的预编码。 这里公开的是使用一维二维预编码器从多个天线发射信号的一般方法。 该预编码器固定在由P个子载波和Q个OFDM符号（P和Q的值大于或等于1）组成的给定资源块（RB）或时隙中。 每个资源块中的预编码器可以采用跨越二维时频网格的相同或不同的值。 选择预编码器作为RB的逻辑频率索引或物理频率索引的函数。
