An apparatus is disclosed for transmission setting selection. In an example aspect, an apparatus includes a wireless interface device with a communication processor and a radio-frequency front-end. The communication processor is configured to provide a signal. The radio-frequency front-end is coupled to the communication processor and configured to accept the signal. The radio-frequency front-end includes an amplifier configured to amplify the signal based on one or more amplifier settings. The wireless interface device is configured to adjust the one or more amplifier settings responsive to an output power being changed with a gain being unchanged.

Transmission setting selection

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transceiver chain may receive, using a downconverter tuned by at least one local oscillator, transmit signals that are modulated using a modulation bandwidth and that span a total bandwidth greater than or equal to the modulation bandwidth. The at least one local oscillator may cover a first fraction of the total bandwidth. The transceiver chain may receive, using at least one analog-to-digital converter, input from the downconverter, and may output a first digital signal based at least in part on the input and sampling at the first fraction of the total bandwidth. The transceiver chain may determine an error associated with the transmit signals based at least in part on the first digital signal, and may perform digital pre-distortion on new signals based at least in part on the error. Numerous other aspects are described.

Hardware optimization for 5G fractional bandwidth digital pre-distortion

Certain aspects of the present disclosure relate to methods and apparatus for power amplifier control. A power amplifier network includes a first path comprising a first power amplifier. The power amplifier network further includes a second path comprising a second power amplifier. The power amplifier network further includes a common input path to both the first path and the second path. The power amplifier network further includes a first power control network for controlling a first signal applied to the first power amplifier. The power amplifier network further includes a second power control network for controlling a second signal applied to the second power amplifier, wherein the first power control network is different from the second power control network.

Digital pre-distortion for multi-antenna systems

Embodiments include systems and methods for managing an adaptive interference filter performed by a device processor of a mobile communication device. A device processor may determine whether a transmission power from the mobile communication device is greater than or equal to a transmit power threshold. The device processor may determine whether a ratio of interference in a received signal to a level of the received signal including noise (interference ratio) is greater than or equal to an interference ratio threshold in response to determining that the transmission power is greater than or equal to the transmit power threshold. The device processor may perform interference cancellation with the adaptive interference filter in response to determining that the interference ratio is greater than or equal to the interference ratio threshold. In some embodiments the adaptive interference filter may be a non-linear interference cancellation filter.

Method and apparatus for self-directed interference cancellation filter management

Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. A victim receiver may obtain a non-linear interference cancelation (NLIC) signal from an aggressor transmitter of a communication device. The NLIC signal may be based, at least in part, on a source transmit signal that has been distorted by digital pre-distortion (DPD) at the transmitter. An NLIC unit may reconstruct a cancelation signal based on the NLIC signal. A receiver may remove the cancelation signal from a received signal.

Selection of non-linear interference cancelation (NLIC) input

Disclosed are various embodiments for circuitry that generates a sync code for wireless transmission. The system generates a sync word according to an identifier of the transmitter, the sync word being unique under a cyclic shift of the sync word. The system inserts a plurality of instances of the sync word into a data stream. The system also transmits, via the transmitter, the data stream to a receiver, the receiver being operable to perform a sliding correlation operation on the sync word.

Generating codes for sync words to avoid cyclic collision

Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. An aggressor transmitter may provide two or more non-linear interference cancelation (NLIC) signals, including a first NLIC signal and a second NLIC signal. A NLIC unit may reconstruct an interference signal based on a selected one of the first NLIC signal or second NLIC signal. Power of the transmitted signal at the aggressor transmitter may be used to select either the first interference cancelation signal or the second interference cancelation signal. The first and second NLIC signals may differ by the use of digital pre-distortion (DPD) at the aggressor transmitter.

Detecting a wireless device is disclosed. A situation in a wireless medium is created for the wireless device to transmit. A transmission of the wireless device is received. The wireless device is detected based at least in part on information associated with the received transmission of the wireless device.
