These carrier-specific metrics may include a maximum-power reduction or cubic metric determined for that carrier as if it would be transmitted alone. In one embodiment, estimation of the required back-off is based on a weighted sum of the carrier-specific metrics, where the weights applied depend on a power ratio. Only a few relatively small look-up tables or simple computations are required in this case: one for obtaining the carrier-specific metrics based on configuration parameters of each carrier, and another for obtaining the weights based on the power ratio. Accordingly, methods and apparatus herein advantageously require less computational complexity and/or memory usage than that needed if estimating the required back-off based on similar metrics obtained for the multi-carrier signal as a whole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-carrier transmitter back-off estimation","description":"Methods and apparatus taught herein estimate the amount by which to reduce a multi-carrier signal's maximum transmit power based on metrics specific to each carrier of the multi-carrier signal.
