Abstract  Abstract

The invention claims claims technology for uplink power control signaling for semi-persistent scheduling using carrier aggregation. A method comprising: receiving identifying information of the position of the transport power control (TPC) carrier aggregation (CA) physical downlink control channel (PDCCH) information element (IE) to use semi-persistent scheduling uplink power control adjustment of the selected component carrier by the UE. TPC-CA-PDCCH configuration IE includes a carrier index value of the selected component carrier of the UE so as to allow selection of the component carrier power levels are individually adjusted. a physical uplink shared channel and/or physical uplink control channel power level may be adjusted for the selected component carrier.

Technology for providing uplink power control signaling for semi-persistent scheduling with carrier aggregation is disclosed. One method comprises receiving a transmitter power control (TPC) carrier aggregation (CA) physical downlink control channel (PDCCH) configuration information element (IE) identifying a location of information to adjust an uplink power control of a selected component carrier of the UE using semi-persistent scheduling. The TPC-CA-PDCCH configuration IE includes a carrier index value for the selected component carrier of the UE to allow a power level of the selected component carrier to be individually adjusted. A power level of a physical uplink shared channel and/or a physical uplink control channel can be adjusted for the selected component carrier.
