Abstract: Techniques for reducing or eliminating effects of noise on a wireless communication system are provided. In one aspect of the invention, the technique comprises monitoring noise attributable to an interference source that may affect one or more components of the wireless communication system. The interference source being monitored is distant from the wireless communication system to the degree that noise arrives at the wireless communication system within a substantially point source-like angular range. For example, the noise may be attributable to the sun or tropospheric ducting. The technique then comprises initiating one or more operations, as a function of the monitored noise, to reduce or eliminate the effects of the noise attributable to the distant interference source at one or more of the components of the wireless communication system that are determined to be affected by such noise.

Abstract: In one aspect of the present invention, a method for controlling a communications session with a mobile device is provided. The method comprises selecting a plurality of base stations, where at least a portion of the base stations are adapted to operate as a secondary agent, and wherein the secondary agent is capable of communicating with a mobile device. Substantially similar data is then delivered to a plurality of the secondary agents, and a first one of the secondary agents is selected as a first serving secondary agent to communicate with the mobile device. The first serving secondary agent transfers the data to the mobile device during the communications session.

Abstract: A method for controlling a wireless communications system is provided. A plurality of substantially identical base stations, each capable of being operated as both a primary agent and a secondary agent are deployed. The secondary agent is capable of communicating with a mobile device and the primary agent is capable of communicating with a network. A network active set associated with a mobile device is formed from a plurality of the base stations. One of the base stations in the network active set is selected to operate as the primary agent, and it communicates to the other base stations that the selected base station is operating as the primary agent. Thus, communications between the network and the mobile device are routed through the primary agent and the selected secondary agent.

Abstract: A method for locating a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises associating the mobile device with a first base station of the plurality of base stations. Thereafter, a paging signal is delivered from a subset of base stations associated with the first base station to the mobile device. The subset of base stations may correspond to a network active set of base stations associated with the mobile device. Thereafter, when a signal from one of the base stations in the subset of base stations is received, indicating that the mobile device responded to the paging signal from the one base station, then the mobile device is located and may be associated with the one base station for future paging attempts.

Abstract: Wireless telecommunications apparatus and method. A base station sends data to a user terminal on a first channel at a first frequency in selected time slots and the user terminal sends data to the base station at a second frequency in selected time slots. These two frequencies are different. The network also either includes a transmitter which transmits further data to the user equipment at a third frequency in time slots in which the other data is not being sent or includes a receiver which receives further data from the user equipment at the third frequency in time slots in which the other data is not being sent. The apparatus can be a UMTS or other third generation system.

Abstract: A method for achieving improved piezoelectric films for use in a resonator device is disclosed. The method is based on applicant's recognition that the texture of a piezoelectric film (e.g., as used in a piezoelectric resonator) is directly affected by the surface morphology of the underlying electrode, and additionally, the surface morphology of the electrode is affected by the surface morphology of the underlying oxide layer or Bragg stack. Accordingly, the invention includes a method of making a device having a piezoelectric film and electrode including controlling the deposition and surface roughness of the electrode and optionally, the Bragg stack.

Abstract: The present invention provides a method for tuning a thin film resonator (TFR) filter comprising a plurality of TFR components formed on a substrate. Each of the TFR components has a set of resonant frequencies that depend on material parameters and construction. TFR bandpass filter response for example can be produced by shifting the set of resonant frequencies in at least one of the series branch TFR components so as to establish the desired shape of the bandpass response and the desired performance of the filter. The shifting may be advantageously performed by removing piezoelectric material from the series branch TFR component, providing a TFR filter with bandwidth and attenuation advantages over that conventionally achieved by down-shifting resonant frequency sets of the shunt TFR components by adding metal material.

Abstract: A thin film resonator (TFR) filter circuit including a plurality of TFRs connected in a series-shunt or shunt-series arrangement between input and output ports of the filter. A method is provided that allows for the shifting of resonant frequency sets in each TFR in respective series arms and shunt legs of the TFR filter circuit, as opposed to a conventional concatenating approach using a plurality of chained-up building blocks of TFRs, where resonant frequency sets in each of the series arms are equal, and where resonant frequency sets in each of the shunt legs are equal. Additionally, each TFR in the filter may have a unique parallel plate electrode capacitance, as opposed to the conventional concatenating approach where all series arm electrodes in the root filter design have equal capacitance, and where all shunt leg electrodes have equal capacitance.
