Abstract
A technique of operating a wireless communication device in a multiple-input multiple-output wireless communication system includes receiving, at a first wireless communication device, recommended precoder information from a second wireless communication device, which is associated with a recommended precoder. A precoded signal is then formed at the first wireless communication device based on the recommended precoder or an alternate precoder. The first wireless communication device, which is configured to not provide an indication of whether the recommended precoder or the alternate precoder was utilized to form the precoded signal, then transmits the precoded signal.
