Abstract: In an ad hoc peer-to-peer communication network between wireless devices, a low priory first receiver device calculates and provides three transmission rates to its corresponding first transmitter device to allow higher priority devices to concurrently use a shared frequency spectrum. The first receiver device may wirelessly receive a first pilot signal from the first transmitter device and a second pilot signal from a second transmitter device. The second pilot signal indicating that the second transmitter device intends to transmit a second traffic signal that will interfere with the first traffic signal. The first receiver device then determines 1) a first transmission rate as a function of the second pilot signal, 2) a second transmission rate as a function of the first and second pilot signals, and 3) a third transmission rate as a function of the first pilot signal. The three transmission rates are then sent to the first transmitter device.

Abstract: A wireless networking method includes placing a master device and at least one peripheral device within proximity of each other. A radio frequency request for proximity pairing is transmitted from the peripheral device to the master device. Radio frequency proximity pairing signals implementing the proximity pairing are transmitted from the master device to the peripheral device. The proximity pairing signals are transmitted with a first level of transmission power. After the proximity pairing is complete, operational signals are transmitted from the master device to the peripheral device. The operational signals are transmitted with a second level of transmission power greater than the first level of transmission power.

Abstract: Reverse link interference can be controlled by utilizing a dynamic and changeable IoT setpoint, which is a quantitative measurement of total interference received at a base station. The interference can occur when a mobile device in an adjacent sector is communicating over the reverse link. The IoT setpoint can be changed based on conditions occurring in the sector and/or scheduling information for the future. A fast up indicator (Up+) can be transmitted for reverse link interference, which allows the receiving device to take advantage of the fact that additional interference created will not affect the sector. An interference control action can be transmitted in an Other Sector Interference Bit (OSIB) channel over the air or over the backhaul. The interference control action can be determined as a function of the dynamic IoT setpoint.

Abstract: Provided is a high frequency module capable of reducing the IMD. During the transmission/reception operation based on W-CDMA, control signals VSWCC, VTRXCC are output as Hi signals from a control logic. Consequently, transistor T1 is turned ON, and transistors T2, T3 are respectively turned OFF. When the transistor T1 is turned ON, the voltage output from an operational amplifier is output as the signal VVSW to a control terminal, and the control signal VTRXC is output as a Hi signal. The signal VVSW is of a voltage level that is lower than that of the control signal VTRXC. The control signal VTRXC is a signal for turning ON a transistor circuit Q1, and the signal VVSW is a signal for supplying a DC voltage to the antenna potential. It is thereby possible to reduce the ON resistance of the transistor circuit Q1 and improve the IMD characteristics.

Abstract: An RFID communication system comprising a near field coupler that is capable of selectively communicating with a targeted transponder positioned among a group of multiple adjacent transponders. The coupler is configured to receive communication signals from a transceiver and transmit the signals to a targeted transponder in a transponder operating region. The coupler includes a number of radiating elements spaced apart and a switching element. The switching element selectively couples one or more of the radiating elements to the transceiver. The coupled elements transmit the signals into the transponder operating region by emanating a near field effect. The pattern of the near field effect may be adjusted by changing the combination of the coupled radiating elements.

Abstract: A local oscillator communicates a signal of relatively low frequency across an integrated circuit to the location of a mixer. Near the mixer, a frequency-multiplying SubHarmonically Injection-Locked Oscillator (SHILO) receives the signal and generates therefrom a higher frequency signal. If the SHILO outputs I and Q quadrature signals, then the I and Q signals drive the mixer. If the SHILO does not generate quadrature signals, then a quadrature generating circuit receives the SHILO output signal and generates therefrom I and Q signals that drive the mixer. In one advantageous aspect, the frequency of the signal communicated over distance from the local oscillator to the SHILO is lower than the frequency of the I and Q signals that drive the mixer locally. Reducing the frequency of the signal communicated over distance can reduce power consumption of the LO signal distribution system by more than fifty percent as compared to conventional systems.

Abstract: A mobile device estimates channel state information (CSI) comprising, for example, CQI and/or SNR, for a downlink channel. The estimated CSI is non-uniformly quantized and transmitted to the base station over a finite-rate feedback channel. Different portions of the estimated CSI are quantized using different quantization step sizes, which are determined according to a performance metric function such as a channel capacity function of the estimated CSI. A quantization step size for a portion of the estimated CSI is increased if a low distribution probability is indicated by the portion of the estimated CSI. A quantization step size for a portion of the estimated CSI is decreased if a high distribution probability is indicated. The mobile device quantizes the estimated CSI using the determined quantization step sizes to transmit to the base station over the finite-rate feedback channel. Downlink data transmission is received according to the transmitted CSI.

Abstract: 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.
