Shaping Table Reconfiguration At Communication Event Boundaries

摘要

A communication device, such as a smart phone, receives a power specification message from a network controller. The power specification message specifies an output power applicable for a particular communication subframe or symbol within the subframe. In response to the power specification message, the communication device determines a new shaping table and replaces an existing shaping table with the new shaping table. The communication device uses the shaping table to generate an envelope signal for an envelope tracking power supply, and the new shaping table is adapted to provide power saving operation at the specified output power.
