A method for enabling more accurate scheduling of future uplink transmissions on uplink component carriers not scheduled by an eNodeB is provided. User equipment (UE) includes a UE and Calculate the virtual power headroom of unscheduled uplink component carriers based on the virtual uplink resource allocation preconfigured by the eNodeB. The maximum transmission power of the UE is set to a fixed value configured in advance, or calculated by the UE in consideration of power reduction, and 0 is set to the uplink transmission power. The virtual power headroom is transmitted to the eNodeB, which can then infer the unscheduled uplink component carrier path loss and / or power per resource block and is used by the UE It is also possible to infer the power savings to be made [Selection] Figure 24 |
