Abstract
A method of providing delay information in a multi-antenna transmission system is provided. A time delay value is selected from a set of time delay values. A mobile station is informed of information related to the selected time delay value. The same data is transmitted from a first antenna and from a second antenna. The data is transmitted from the second antenna after the data is transmitted from the first antenna according to the selected time delay value. The time delay value is selected based on a deterministic method or a random method.
