Abstract: The various embodiments provide methods implemented in a MSMA communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a MSMA communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.

Abstract: A method of wireless communication enables an inter-radio access technology (IRAT) neighbor cell measurement when a serving RAT signal strength is continuously below a first threshold value for a first length of time. The method also disables the IRAT neighbor cell measurement when the serving RAT signal strength is continuously above a second threshold value for a second length of time.

Abstract: Methods for improving the time to acquire an identity of a base station by a mobile station, by relying on locally-unique attributes of the base stations instead of globally-unique attributes of the base stations, are presented. In some embodiments, data may be requested, the data may contain a globally unique attribute of a base station, a first locally unique attribute of the base station, and a second locally unique attribute of the base station. In some embodiments, data may be received in response to the request, the data may contain at least the first locally unique attribute and the second locally unique attribute. It may then be determined that the data did not contain the globally unique attribute, and an identity of the base station based at least in part on the first locally unique attribute and the second locally unique attribute may be acquired.

Abstract: Methods, systems, and devices for wireless communications are described. The described methods, systems, and devices may include sampling an input signal to obtain one or more signal windows. An amplitude of a first sample within a first signal window of the one or more signal windows may be determined to exceed an amplitude threshold. A series of cancellation pulses may be combined with the first sample within the first signal window to obtain a reduced signal, the reduced signal including one or more reduced samples each having an amplitudes within the amplitude threshold. The series of cancellation pulses may be based on a characteristic of the first sample. The reduced signal may then be transmitted. The series of cancellation pulses may be based on, for example, an envelope of the first sample. In some cases, the series of cancellation pulses may be based on a phase of the first sample.

Abstract: A process of wireless communication for obtaining channel quality information alignment includes predicting a channel state of a future downlink subframe of a signal. The process also includes providing a base station with a set of parameters based on the predicted channel state. For example, a user equipment (UE) can obtain a recommended transport block size (RTBS) from the predictor process, and return the RTBS to the base station as one of the set of parameters.

Abstract: The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a multilayer perceptron neural network with Hammerstein structure by dividing an aggressor signal into real and imaginary components, augmenting the components by weight factors, executing a linear combination of the augmented components, and executing a nonlinear sigmoid function for the combined components at a hidden layer of multilayer perceptron neural network to produce a hidden layer output signal. At an output layer, hidden layer output signals may be augmented by weight factors, and the augmented hidden layer output signals may be linearly combined to produce real and imaginary components of an estimated jammer signal. A linear filter function may be executed for the components of the jammer signal, and to produce a nonlinear interference estimate used to cancel the nonlinear interference of a victim signal.

Abstract: A method and apparatus for controlling uplink transmit power with optimum delay is described. A transmit power control command may be received. A time slot of the transmit power control command may be determined. Based on the time slot, it may be determined to decode the transmit power control command, with a delay. The transmit power control command may be decoded, after the delay, using a transmit power control command decoding graph by determining a strength of the transmit power control command and plotting the strength on the transmit power control command decoding graph. The transmit power control command decoding graph may include regions. Decoding the transmit power control command, after the delay, may be based on a region associated with plotting the strength of the transmit power control command.

Abstract: The various embodiments include methods and apparatuses for cancelling nonlinear interference during concurrent communication of dual-technology wireless communication devices. Nonlinear interference may be estimated using a multilayer perceptron neural network by augmenting aggressor signal(s) by weight factors, executing a linear combination of the augmented aggressor signals, and executing a nonlinear sigmoid function for the combined aggressor signals at a hidden layer of multilayer perceptron neural network to produce a hidden layer output signal. Multiple hidden layers may repeat the process for the hidden layer output signals. At an output layer, hidden layer output signals may be augmented by weight factors, and the augmented hidden layer output signals may be linearly combined to produce an estimated nonlinear interference used to cancel the nonlinear interference of a victim signal. The weight factors may be trained based on a determination of an error of the estimated nonlinear interference.
