Abstract  Abstract

FIELD: radio engineering communication.SUBSTANCE: invention relates to methods for informing an eNodeB on the transmit power status of user equipment in a mobile communication system using component carrier (CC) aggregation. The invention proposes procedures that allow the eNodeB to recognise the power usage status of UE in a communication system using carrier aggregation. The UE indicates to the eNodeB when the UE is close to using its total maximum UE transmit power or when it has exceeded same. This is achieved by the UE including indicator(s) and/or new MAC CE to one or more protocol data units transmitted on respective component carriers within a single sub-frame for providing the eNodeB with power status information. The MAC CE may report a per-UE power headroom. Alternatively the MAC CE may report per-CC power headroom values and/or power reduction values applied to the respective uplink CC.EFFECT: improved information.14 cl 33 dwg 1 tbl
