Abstract
A method for and wireless communications unit adapted for measuring transmission performance for a signal emanating from an antenna is discussed. The wireless communications unit includes a receiver for receiving the signal in a first and a second time interval to provide, respectively, a first and a second signal; and a channel processor for assessing a relative channel metric corresponding to the first and second signal, the relative channel metric indicative of the transmission performance of a transmission mode. A corresponding method and base transmitter is also arranged and adapted for adjusting a transmission mode based on measured transmission performance and includes a transmitter for sending the signal in the first and second time interval and a base channel processor for determining a channel metric corresponding to the first and second signal, the channel metric indicative of the transmission performance; the transmitter further sending a control signal corresponding to the transmission mode adjusted according to the transmission performance.
