Shaping Table Reconfiguration At Communication Event Boundaries

A method comprising:

• in user equipment:
• receiving a power specification message from a network controller, the power specification message specifying an output power;
• determining a new shaping table in response to the output power;
• replacing an existing shaping table with the new shaping table;
• and
• generating an envelope signal for a power supply with the new shaping table.

A system comprising:

• a baseband controller;
• a shaping table in communication with the baseband controller, the shaping table operable to modify input signal samples to provide envelope tracking signals characterized by a signal envelope;
• an envelope tracking power supply operable to receive the envelope tracking signals and output a power supply voltage signal that approximates the signal envelope;
• and
• a power amplifier operable to receive the power supply voltage signal and drive a transmit antenna;
• where:
• the baseband controller is operable to:
• obtain the input signal samples corresponding to a desired transmit signal;
• provide the input signal samples to the shaping table;
• determine an upcoming communication event;
• respond to the upcoming communication event by determining a modification to the shaping table for handling the upcoming communication event;
• and
• apply the modification to the shaping table in preparation for the upcoming communication event.
