Publication number: 20170325101Abstract: Embodiments described herein provide a method and apparatus for monitoring and correcting a transmit signal. A first sample is taken before the signal is input to a digital to analog converter (DAC) in a transmit chain. A second sample is taken of the transmit signal after the signal has passed through the power amplifier (PA). The first and second transmit samples are then compared and an equalizer interpolation value is determined. This equalizer interpolation value is applied to the transmit signal before transmission to provide a transmit signal with improved quality. The apparatus includes a feedback receive correction unit; a time domain processor in communication with the feedback receive correction unit; a frequency domain processing equalizer in communication with the time domain processor; an equalizer interpolation unit; an absolute value squaring unit in communication with the equalizer interpolation unit; and a processor for computation of a transmit quality parameter.Type: ApplicationFiled: May 6, 2016Publication date: November 9, 2017Inventors: Joseph Gates, Li Gao, Narendra Gottimukkala, Douglas Grover, Insung Kang, Dongbo Zhang

Patent number: 9484974Abstract: 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.Type: GrantFiled: September 9, 2015Date of Patent: November 1, 2016Assignee: QUALCOMM IncorporatedInventors: Sheng-Yuan Tu, Farrokh Abrishamkar, Parisa Cheraghi, Insung Kang, Reza Shahidi

Publication number: 20160183192Abstract: A user equipment (UE) controls power consumption of the UE based on mobility information and channel conditions experienced by the UE. In one instance, the UE determines its level of mobility based on a Doppler frequency spread of received communications. The UE disables a motion sensor when the level of mobility is above a first threshold. The UE then controls the communications based on the motion sensor and channel conditions experienced by the UE when the level of mobility is below the first threshold.Type: ApplicationFiled: April 17, 2015Publication date: June 23, 2016Inventors: Insung KANG, Ping ZHOU, Chao JIN, Thawatt GOPAL, Shanshan WANG, Disha AHUJA, Rashmi KULKARNI, Josephine BOLOTSKI, Justin MCGLOIN, Carlos PUIG

Patent number: 9331818Abstract: A method and apparatus for improved downlink data transport with hybrid automatic repeat request (HARQ) feedback and a measurement gap are provided. A user equipment (UE) receives from a network a transmission grant for downlink data on a first control channel. The UE receives the data from the network via a transport channel. In response to the received data, the UE determines whether transmission of an acknowledgement message falls in a measurement gap. Upon determining that the transmission of the acknowledgement message by the UE falls in the measurement gap, and prior to receiving from the network a retransmission grant for the data on the first control channel, the UE sends the acknowledgement message on a second control channel in a sub-frame following the measurement gap. The first control channel is associated with the second control channel.Type: GrantFiled: April 23, 2014Date of Patent: May 3, 2016Assignee: QUALCOMM IncorporatedInventors: Ming Yang, Insung Kang, Tom Chin
