Abstract  Abstract

The invention claims techniques for uplink power control in a wireless network. The invention claims the component carrier at a position receiving component carrier list of the user equipment (UE) wherein the packet in the list with one or more of the uplink transmission on those component carrier common features related to unnecessary power. Therefore when the component carrier downlink carrier in the component list is executed by path loss estimate may be used to control the other component carriers of the uplink transmission in the list. Furthermore the UE may receive path loss difference parameter which provides an offset of one or more factors which is related to component carrier having specific characteristics with respect to these factors and has the necessary power of the uplink component carriers of different properties with respect to these same factors between transmission.

Technology for uplink power control in a wireless network is disclosed. Receiving a component carrier list at a User Equipment (UE) is disclosed where the component carriers grouped in the list have one or more common characteristics relative to the power necessary for uplink transmission on those component carriers. A path-loss estimation performed on the downlink of a component carrier in the component carrier list can therefore be used to control uplink transmission for other component carriers in the list. Additionally a UE can receive a path-loss difference parameter providing an offset for one or more factors related to the power necessary for uplink transmission between a component carrier with certain characteristics relative to those factors and a component carrier with different characteristics relative to those same factors.
