Abstract
A wireless communication device is configured for performing uplink transmission power control. The wireless communication device includes a processor and instructions stored in memory. The wireless communication device performs uplink transmission power control for multiple regulated frequency bands or component carriers. The wireless communication device determines a total transmission power for at least one component carrier and allocates transmission power to at least one antenna.
Claims6
A wireless communication device comprising:
- a transmitting unit configured to transmit one or more physical uplink shared channels (PUSCHs) on one or more uplink component carriers;
- and
- an uplink power control unit configured to determine a transmission power for physical uplink shared channel (PUSCH) for each component carrier,
- wherein the transmission power for PUSCH for each component carrier is obtained by scaling a projected transmission power for the PUSCH in a case that a sum of projected values exceeds a maximum transmission power of the wireless communication device,
- wherein the sum of projected values is a sum of projected PUSCH transmission powers for component carriers and projected physical uplink control channel (PUCCH) transmission power, and
- wherein the maximum transmission power of the wireless communication device is predefined based on a user equipment (UE) power class of the wireless communication device.

A method performed by a wireless communication device, comprising:
- transmitting one or more physical uplink shared channels (PUSCHs) on one or more uplink component carriers;
- and
- determining a transmission power for a physical uplink shared channel (PUSCH) for each component carrier,
- wherein the transmission power for the PUSCH for each component carrier is scaled from a projected transmission power for the PUSCH in a case that a sum of projected values exceeds a maximum transmission power of the wireless communication device,
- wherein the sum of projected values is a sum of projected PUSCH transmission powers for component carriers and projected physical uplink control channel (PUCCH) transmission power, and
- wherein the maximum transmission power of the wireless communication device is predefined based on a user equipment (UE) power class of the wireless communication device.
