??and/orreceiving information jointly, we show that tremendous

??energy saving is possible for transmission distances larger than a

??given threshold, even when we take into account the local energy

??cost necessary for joint information transmission and reception.

??We also show that over some distance ranges, cooperative MIMO

??transmission and reception can simultaneously achieve both

??energy savings and delay reduction.
