摘要：The disclosure relates to methods and apparatuses that facilitate power andquality control of uplink MIMO transmissions. A method in a NodeB comprisescontrolling (50) transmission power of multiple pilot signals transmitted by a userequipment by using a single inner power control loop operating on at least one pilotsignal of the multiple pilot signals. Some disclosed embodiments also relate to

adjustment (60) of a quality target applied by the single inner power control loop and toupdating (71, 72) of a power offset for computing the number of bits that the userequipment can transmit on a stream that is associated with a pilot signal that is notpower controlled by the single inner power control loop.
