The present disclosure sets forth multiple embodiments of the invention. Among those embodiments is a method for managing the power of an uplink signal (e.g., an LTE PUSCH or PUCCH). The method involves determining a convolution of a first function and a second function (which may be power density functions) of the uplink signal and determining the power of the uplink signal based on the convolution. The uplink signal comprises one or both of a data signal (transmitted over a PUSCH, for example) and a control signal (transmitted over a PUSCH or PUCCH, for example). The uplink signal is transmitted over one or more subcarriers (which may be carried by resource blocks, for example).
