Abstract
A method includes, in a wireless communication terminal that transmits a data channel over multiple component carriers, dividing a total transmit-power allocation specified for the data channel into carrier-specific power allocations for the respective component carriers. Block sizes, which specify respective numbers of bits for transmitting the data channel, are initially derived for one or more of the component carriers from a quantized set of block sizes, such that the respective carrier-specific power allocations are not exceeded. For at least a selected component carrier, an extended block size is selected from the quantized set. The extended block size exceeds a carrier-specific power allocation assigned to the selected component carrier, but together with the block sizes of the other component carriers does not exceed the total transmit-power allocation. The data channel is transmitted over the component carriers using the selected block sizes, including the extended block size.
