Abstract: This disclosure proposes a mobile communication system to use multiple power control loops in the uplink. Each power control loop may be associated with a respective antenna beam transmitted from an antenna array of the electronic device (e.g. UE) in the uplink of the communication system. Each power control loop may also be associated with a respective set of one or more MIMO layers. This concept is applicable to open-loop, closed-loop power control or both.
