  • Patent number: 9088308
    Abstract: In an up-converter path of a transmitter, wide-band signal system like direct conversion WiGig, a high pass filter (HPF) is placed in the baseband path after the low pass filter (LPF) but before the mixers. The baseband signal of WiGig can have a bandwidth of 800 MHz. The HPF removes the frequencies from 0-40 MHz from the baseband signal and degrades the overall signal of the baseband by a dB or so. However, the frequency pulling is significantly reduced since oscillator frequency and Radio frequency (RF) transmitter frequencies after conversion become further separated when compared a system using to the conventional approach. This causes the injected signal to fall outside the locking range of the oscillator. The concern of substrate coupling is reduced and allows for a reduction in the physical distance between the oscillator and the mixer and reduces a shift in the desired target frequency of operation.

    Abstract: This disclosure describes wireless communication techniques, protocols, methods, and devices applicable to a docking system environment in which aspects of wireless docking may function using vicinity-based undocking techniques. In some examples, the techniques of this disclosure enable a wireless docking center to undock a wireless dockee in a situation where a wireless dockee moves out of the vicinity of a wireless docking center so as to prevent malicious users from using peripheral devices available through the wireless docking center to interact with the wireless dockee without the wireless dockee user's knowledge. In other examples, the wireless dockee may undock itself from a wireless docking center when the wireless dockee moves out of the vicinity of a wireless docking center.

  • Patent number: 8885692
    Abstract: Embodiments of the present invention provide an apparatus comprising a transceiver having a receiver and a transmitter connected through a segment of a calibration loop back path. The apparatus also comprises a control system configured to communicate with the transceiver. The calibration loop back path has an intentional phase shift that can be toggled between an off state and an on state by the control system. The control system is configured to calculate the intentional phase shift by examining the difference of a first and second phase angle. The first phase angle is obtained from the transmission of a first pair of signals with the intentional phase shift in the off state. The second phase angle is obtained from the transmission of a second pair of signals with the intentional phase shift in the on state.

    Abstract: It is described a communication end device comprising (a) a radio transceiver comprising a receiver for receiving radio signals from a transmitting network entity of a cellular telecommunication network and a transmitter (110, 120, 130) for transmitting radio signals to a receiving network entity of the cellular telecommunication network, (b) a further receiver (140) for receiving a further radio signal, and (c) a control circuit (150, 162, 164), which is coupled to the radio transceiver and to the further receiver (140). The control circuit (150, 162, 164) is configured for generating a control signal for controlling the operation of the further receiver (140). Thereby, the control signal is based on a synchronization signal being related to a time dependent transmission scheme of the transmitter (110, 120, 130) and on an information about the current operational state of the radio transceiver.

  • Patent number: 8838046
    Abstract: A hybrid FDM/TDM solution for in-device coexistence interference avoidance is proposed. A user equipment (UE) comprises a first radio transceiver and a second co-located radio transceiver. The UE detects coexistence interference between the two radios based on radio signal measurement. The UE sends an IDC interference indicator to its serving base station (eNB). The UE also reports IDC information including recommendation for FDM and TDM configurations to the eNB. The eNB receives the IDC interference indicator and evaluates whether to trigger FDM-based solution to mitigate the coexistence interference. The eNB also evaluates whether to trigger TDM-based solution to mitigate coexistence interference. The evaluation is based on the recommended FDM and TDM configurations. The eNB may trigger FDM-based solution, TDM-based solution, or FDM and TDM solution based on the evaluation results of the feasibility and effectiveness of each solution.

  • Patent number: 8831164
    Abstract: Enhanced reception in a communication system is achieved by applying a time domain generated time-reversed channel response to signals transmitted from a group of transmitter to a group of receivers. The time-reversed channel response is generated from a radio frequency channel response derived from signals previously received from the group of receivers, but reversed in the time domain. The time-reversed channel response is convolved with an information signal that when transmitted in a coordinated fashion from the group of transmitters, the signals arrive at each receiver in the group of distant receiving communication devices at approximately the same time where the signals coherently combine, thereby increasing signal power at the receivers. This permits detection at a greater range or with a lower bit error rate. In addition, the many-to-many configuration enables signal power from each transmitter to be focused temporarily and spatially on each receiver.
