Abstract: This disclosure proposes 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. For example, a beam (or uplink signal) may be associated with 1, 2 or even more MIMO layer. Hence, in this latter case, each power control loop may be associated with a respective set of one or more MIMO layers. This concept is application to open-loop, closed-loop power control or both.
