Abstract
A first applied Additional Maximum Power Reduction (A-MPR) can be determined as the maximum of a first A-MPR and a second A-MPR if a device is configured for carrier aggregation. A second applied A-MPR can be determined as the maximum of a third A-MPR and a fourth A-MPR if the device is configured for transmission only on the primary cell. A transmitter can be configured for carrier aggregation transmission if the first applied A-MPR is less than or equal to the second applied A-MPR. The transmitter can be configured for transmission only on the primary cell if the second applied A-MPR is less than the first applied A-MPR. The uplink control channel can be transmitted with a power reduction no greater than the applied A-MPR for the selected transmitter configuration.
Claims14
A method comprising:
- ascertaining, at a device, a first additional maximum power reduction for a first resource block of a physical uplink control channel transmission if the device is configured for carrier aggregation transmission;
- ascertaining a second additional maximum power reduction for a second resource block of a physical uplink control channel transmission if the device is configured for carrier aggregation transmission;
- determining a first applied additional maximum power reduction as the maximum of the first additional maximum power reduction and the second additional maximum power reduction if the device is configured for carrier aggregation;
- ascertaining a third additional maximum power reduction for a first resource block of a physical uplink control channel transmission if the device is configured for transmission only on a primary cell;
- ascertaining a fourth additional maximum power reduction for a second resource block of a physical uplink control channel transmission if the device is configured for transmission only on the primary cell;
- determining a second applied additional maximum power reduction as the maximum of the third additional maximum power reduction and the fourth additional maximum power reduction if the device is configured for transmission only on the primary cell;
- configuring a transmitter for carrier aggregation transmission if the first applied additional maximum power reduction is less than or equal to the second applied additional maximum power reduction;
- configuring the transmitter for transmission only on the primary cell if the second applied additional maximum power reduction is less than the first applied additional maximum power reduction;
- and
- transmitting the uplink control channel with a power reduction no greater than the applied additional maximum power reduction for the selected transmitter configuration.
