Abstract
Provided are a method and an apparatus for information transmission that is performed by a transmitter in a wireless communication system. The method comprises the steps of: acquiring a first resource index and a second resource index; generating information sequences based on the first resource index and the second resource index; and transmitting the information sequences via a first antenna and a second antenna, wherein the second resource index is acquired from the first resource index and the offset.
