Dynamic Operating Bandwidth Configuration for an Envelope Tracker

摘要

A communication device, such as a smart phone, receives operational parameters from a network controller. The operational parameters may include, as examples, bandwidth allocation, center frequency, and receive/transmit band assignments. The operational parameters (e.g., bandwidth allocation) may change on a subframe by subframe basis. In response to the operational parameters, the communication device determines a new configuration for an envelope tracking (ET) power supply. The communication device modifies the ET power supply to implement the new configuration. The new configuration may be chosen to adapt the ET power supply to meet the demands of the operation parameters, without excess power consumption.
