Patent number: 9713158Abstract: Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.Type: GrantFiled: June 21, 2016Date of Patent: July 18, 2017Assignee: QUALCOMM IncorporatedInventors: Tingfang Ji, Peter Gaal, William R. Panton, Gene Fong, Philip D. Coan, Sumit Verma, Edward George Tiedemann, Jr.

Patent number: 9407334Abstract: Exemplary embodiments are directed to reducing jamming caused by radiated fields generated by wireless power transmitters. Exemplary embodiments include detecting a jamming condition of a wireless power receiving device resulting from a radiated field from a wireless power transmitter of a charging device. Such embodiments include synchronizing the wireless power coupling with communication of the wireless power receiving device. Synchronizing wireless power coupling may include wireless power coupling at a first level when the wireless power receiving device is expected to receive a signal on a communication channel. Synchronizing wireless power coupling may further include coupling at a higher rate when the wireless power receiving device is not expected to receive a signal on the communication channel.Type: GrantFiled: November 24, 2014Date of Patent: August 2, 2016Assignee: QUALCOMM IncorporatedInventors: Stanley Slavko Toncich, Philip D. Coan

Patent number: 8964821Abstract: A modem is described. The modem includes a transmitter. The transmitter includes a digital pre-distortion module and a power amplifier. The modem also includes one or more selected shared receivers. The one or more selected shared receivers generate a feedback signal for the digital pre-distortion module. The modem further includes a feedback switch. The feedback switch selectively couples the one or more selected shared receivers to an output of the transmitter.Type: GrantFiled: February 1, 2012Date of Patent: February 24, 2015Assignee: QUALCOMM IncorporatedInventors: Philip D. Coan, Paul J. Draxler, Roberto Rimini, Thomas D. Marra, Gurkanwal Singh Sahota, Steven C. Ciccarelli, Shrenik Patel
