摘要： A system and method may dynamically (a) adjust signal characteristics of individual portions of a Near Field Communication (“NFC”) transmission, and/or (b) change NFC wireless communication channels. A transmitting device may transmit to a receiving device via multiple NFC channels. For instance, a transmitting device may have multiple spatially-separated antennas and/or transmitters, and a transmission required to complete a financial transaction (or other wireless communication) with a receiving device may have several portions. Each transmission portion may be sequentially and/or individually transmitted from the transmitting device to the receiving device using a different antenna and/or transmitter, i.e., a different communication channel. Each channel may use (1) a different antenna and/or transmitter located on the transmitting device, and/or (2) a different level or setting of a signal characteristic, such as transmit at a different power level, phase, frequency, or other characteristic than other channels. As a result, eavesdropping may be inhibited.

摘要： Devices and methods are disclosed for real-time calibration of a tunable matching network that matches the dynamic impedance of an antenna in a receiver. Processing logic is operable to solve multiple non-linear equations to determine the reflection coefficient of the antenna. The tunable matching network is repeatedly perturbed and the power received by the antenna is measured after each perturbation at the same node in the matching network. The measured power values are used by an optimizer in converging to a solution that provides the reflection coefficient of the antenna. The reflection coefficient of the antenna may be used to determine the input impedance of the antenna. The elements of the matching circuit may then be adjusted to match the input impedance of the antenna.

摘要： Methods and devices are disclosed for efficient signaling of discontinuous transmission in a wireless communication system. In various aspects of the disclosure, a user equipment device monitors transmissions on a plurality of physical downlink control channels (PDCCHs) and, in response to said transmissions, generates an acknowledge/negative acknowledge (ACK/NACK) signal comprising a plurality of bits, wherein the plurality of bits includes a discontinuous transmission (DTX) indicator bit. In some embodiments, the indicator bit corresponds to an even or odd number of PDCCHs successfully decoded. In other embodiments, the indicator bit corresponds to an odd or even number of component carriers comprising “TRUE” NACKs.
