摘要： A method and system selects antennas in a wireless network including a base station and user equipment (UE) transceivers. The base station specifies times and frequencies to transmit sounding reference signals (SRSs), and antennas to use to transmit the SRSs for the specified times and frequencies. The transceivers transmit the SRS according to the specified times, frequencies, and antennas. The stopping and starting of the SRS are specified implicitly. The base station selects subsets of the set of available sets of antennas, and indicates the selected subset of antennas to the transceiver.

摘要： Embodiments of the invention facilitate providing wireless links with longer link ranges and/or better suppression of interference than can be provided by the integrated antennas of a typical wireless network node. While, in some cases, it is possible to install intermediate wireless network nodes to hop through long expanses between distant wireless network nodes, it is desirable for distantly spaced wireless network nodes to reach one another through a single transit link (i.e. one hop). This approach is preferable because a single transit link is capable of higher data rates and better interference suppression than multi-hop transit links. The present invention provides methods and apparatus for enhancing the link range achievable by typical wireless network nodes so that distantly spaced wireless network nodes are able to communicate with one another using only a single transit link.

摘要： Handover procedures and a collection of new handover MAC management messages are provided for a wireless mobile multi-bop relay (MMR) network. The types of handovers supported include macro diversity handover (MDHO) and fast access station switching (FASS). The handover procedures for these two types of handover and the MAC messages are described for nine main classes of network topologies. The nine classes of topology are further classified into to main categories, namely, intra multi-hop base station (MR-BS), when and where the handover is in the MMR cell, and inter MR-BS handover, when and where the handover is between two different MMR cells.

摘要： A method for balancing a voltage of an inverter determines an expected voltage of a capacitor based on a voltage of the capacitor at a start of a switching cycle and determines a duty cycle minimizing a value of an objective function representing a difference between the expected voltage of the capacitor and a desired voltage of the capacitor. A switching sequence controlling the inverter is selected based on the duty cycle.

摘要： A spiral resonator is analyzed by modeling a set of loops of the spiral resonator with a model of a circuit including a set of units, wherein each unit includes a resistor and an inductor to model one loop of the spiral resonator. Values of the resistor and the inductor of each unit are based on properties of a corresponding loop. Electrical connection of the loops is modeled by electrically connecting the units in a corresponding order of the loops. A capacitive coupling in the spiral resonator is modeled by connecting adjacent units with at least one capacitor having a value based on the capacitive coupling between two corresponding adjacent loops. An inductive coupling in the spiral resonator is modeled based on inductive coupling between pairs of loops. The operation of the spiral resonator is simulated with the model of the circuit.

摘要： Inverter is modulated based on first, second, and third switching states determined according to a reference vector represented as a sum of a remainder vector connecting the reference vector with a first vertex of a modulation triangle and a set of vertex vectors connecting a center vertex of space vector diagram with the first vertex. A first switching state of the inverter at the first vertex is determined based on angles of vertex vectors in the set. A second switching state of the inverter at a second vertex of the modulation triangle and a third switching state of the inverter at a third vertex of the modulation triangle are determined based on the first switching state and the remainder vector.

摘要： A battery is charged by first charging the battery at a constant current during a first time interval, and then charging the battery at a varying current during a second time interval. The battery can be a lithium-ion battery, and the charging uses a kinetic model. The kinetic model models the battery having an indiffused well having a capacity c, and a difused well having a capacity 1−c, and the indiffused well is filled directly by the current, and the diffused well is filled only from the indiffused well via a valve with constant inductance.
