1. A method of transmitting signals between a base station and a mobile station in a wireless communication network, the method comprising:
- selecting a desired feedback mode to be one of a rich feedback mode and a limited feedback mode based on an expected performance at a mobile station; and
configuring a base station transmitter based on the desired feedback mode.

Abstract
An adaptive transmission scheme provides multiple levels of adaptation. At a first level, a selection is made between a limited feedback or open loop scheme and a rich feedback or closed loop scheme. At a second level of adaptation, a diversity mode is selected. Additional levels of adaptation could be employed.
