This invention is generally concerned with apparatus, methods and processor control code for MIMO (multiple-input multiple-output) communications systems. <??>An adaptive MIMO communications system comprising a MIMO transmitter (280) and a MIMO receiver (200) and having a feedback path (212) from said receiver (200) to said transmitter (280), said MIMO transmitter (280) including a receiver (282) to receive a feedback signal from said receiver (200) sent via said feedback path (212) and a controller responsive to said feedback signal to configure a MIMO transmission from said transmitter (280) to said receiver (200), said MIMO receiver (200) being configured to receive said MIMO transmission; and wherein said MIMO receiver (200) includes a decision module (210), said decision module (210) having a power indicating input to input a signal indicating a desired receiver power consumption, and an output for sending a MIMO configuration signal to said MIMO transmitter (280), said decision module (210) being configured to determine a MIMO transmission configuration responsive to said power indicating input and to output a MIMO configuration signal for feedback to said transmitter (280) to configure said transmitter (280) in accordance with said determination. <IMAGE>
