摘要：
Methods and apparatuses are provided that include using orthogonal precoding vectors to precode signals for transmission in a given subframe. Transmissions in a first slot of the subframe can be precoded with a first precoding vector, and transmissions in a second slot of the subframe can be precoded with a second precoding vector, which can be orthogonal to the first precoding vector. The precoding vectors can be selected using precoding vector switching or a similar mechanism. Thus, diversity is provided for transmissions within a given subframe to improve reliability of receiving the transmissions. In addition, other precoding vectors can be used to precode signals for transmissions in a subsequent subframe.
