Abstract: A method and telecommunication device in which the telecommunication device is provided with multiple antennas and power amplifiers to provide a beamformed transmit stage. An envelope tracking circuit helps achieve significant power savings in the power amplifier and can be used to provide the power supply for the multiple power amplifiers. A single envelope tracking power supply may be used to produce the supply voltage to the individual power amplifiers that operate on the transmit signal and its phase shifted variant. Accordingly, the user equipment experiences the benefits of both reduced power consumption using the envelope tracker and beam formed transmission.

Abstract: An envelope-tracking (ET) power supply may include a boost control pin. The boost control pin receives a boost enable signal that activates or enables a supplemental power supply in the ET power supply. The supplemental power supply facilitates the generation of a power supply signal for a selected processing stage, e.g., a power amplifier. The supplemental power supply helps the processing stage meet the demands on it caused by the signal that the processing stage needs to handle.

Abstract: An envelope tracking circuit for a transmit and receive path for a telecommunications device includes a filter to reduce the bandwidth of the transmit signal. The envelope of the filtered signal having the lower bandwidth is used to dynamically modulates the power amplifier voltage supply signal. The filter depends on current instantaneous values and also depends in a nonlinear way on instantaneous past and future values of the envelope tracking signal. The filter may be symmetric about peaks of the transmitted signal.

Abstract: A communication device, such as a smart phone, monitors signal transformations and adapts its transmit chain in response. The transformations may include the effect of load angle and load magnitude on a signal prepared for transmission through an antenna. In response to the transformations, the communication device may, for example, determine a new shaping table, and replace 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 may be selected to provide, e.g., power saving operation given the current load angle and load magnitude.

Abstract: 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.

Abstract: A communication device, such as a smart phone, includes an envelope tracking power supply that provides a voltage supply signal for a power amplifier. The envelope tracking signal input to the envelope tracking power supply arises from application of a shaping table on a desired transmit signal. The shaping table implements non-uniform gain compression across a range of output powers, and in particular may aggressively compress the power amplifier for low output powers, and less aggressively compress the power amplifier at high output powers. The non-uniform gain implemented via the shaping table may provide significant power savings, while still allowing the transmitter to meet spectral mask requirements.

Abstract: 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.
