  • Publication number: 20100158174
    Abstract: An apparatus in a wideband radio transceiver for mitigating interference between a wideband radio operating in a wide frequency band and a narrowband radio operating in a narrow frequency band within the wide frequency band. The effects of transmissions by the wideband radio on the narrowband radio are reduced by creating by the wideband radio, a transmitter notch of decreased transmit power centered at a frequency in the wide frequency band that is fixed in relation to the wideband carrier frequency. The wideband carrier frequency is then adjusted so that the transmitter notch is aligned with the second radio's narrow frequency band. The effects of transmissions by the narrowband radio on the wideband radio are reduced by creating by the wideband radio, a fixed receiver notch of decreased receiver gain in the wideband receiver, and aligning the narrowband signal with the fixed receiver notch.

  • Publication number: 20100075600
    Abstract: A first device in a short-range wireless piconet self-learns a multi-frame piconet pattern that is used by a second device as a result of a deferral that reduces or avoids simultaneous transmission and reception by two transceivers at the second device. The first device uses this self-learned multi-frame piconet pattern to selectively control transmitting and receiving by the first device. Power can thereby be conserved at the first device. Related devices, networks and methods are described.

  • Publication number: 20100069014
    Abstract: Some embodiments of the present invention are directed to methods of operating communication terminals. A wireless communication link is established between first and second communication terminals and communication signals are exchanged therebetween. The first communication terminal is controlled to continue over time to increase a power level at which it transmits communication signals to the second communication terminal in response to detecting loss of the wireless communication link and while continuing attempts to reestablish the communication link with the second communication terminal. The first communication terminal is further controlled, in response to detecting loss of the communication link, to increase a level of attenuation that it applies to communication signals from the second communication terminal, and to then more gradually decrease the level of attenuation over time in response to continuing attempts to reestablish the communication link with the second communication terminal.

  • Publication number: 20100069005
    Abstract: A wireless communication terminal includes a RF receiver circuit and a controller. The RF receiver circuit receives communication signals from another communication terminal through a wireless communication link when the communication signals are within a dynamic range of the RF receiver circuit. The controller controls the RF receiver circuit to temporarily increase the dynamic range of the RF receiver circuit in response to detecting an unexpected loss of the wireless communication link between the other communication terminal and the RF receiver circuit. The controller then controls the RF receiver circuit to decrease the dynamic range of the RF receiver circuit in response to detecting that the wireless communication link between the other communication terminal and the RF receiver circuit has been reestablished.

  • Publication number: 20100069084
    Abstract: A method in a network node in control of a cell in a cellular telecommunication network for reducing intra-cell interference between user equipments (UE) residing in said cell and performing random access (RA). The method comprises the steps of arranging groups of preamble sequences where the sequences within each group are orthogonal to each other, assigning one such group to the cell, from which group the UEs performing RA randomly selects a preamble, and assigning one or more additional group(s) of preamble sequences to said cell if the RACH or traffic load exceeds a certain threshold. The invention further relates to a radio network node in a cellular telecommunication system, capable of carrying out said method.

  • Publication number: 20100068996
    Abstract: An electronic communication device includes a high-rate RF wireless transmitter circuit (e.g., a TransferJet transmitter circuit) and a low-rate magnetically coupled receiver circuit (e.g., a Near Field Communication receiver circuit). The high-rate RF wireless transmitter circuit transmits a block of data to another proximately located communication device via RF signals using a first RF communication protocol. The low-rate magnetically coupled receiver circuit receives a communication control signal from the other proximately located communication device via magnetic coupling thereto using a second protocol that is different from the first RF communication protocol, and responds to the communication control signal by selectively triggering the high-rate RF wireless transmitter circuit to transmit another block of data when available for transmission.

  • Patent number: 7657273
    Abstract: A method and apparatus for managing traffic in a network to and from a remote communications device with limited power supply resources. A controller determines the existing power level of the device and uses the determination to control data transmission to and from the device. Data may be transmitted and received by the device by determining the power required to complete a transmission or reception. The controller then determines whether to send the data, redirect the data, cancel the data transmission, or transmit only a portion of the data. The decision is made as to which option to choose based on the amount of power available to complete the data transmission.

  • Publication number: 20100016022
    Abstract: A femtocell base station is configured to transmit site-specific services data to in-range wireless devices, using a common broadcast channel. The site-specific services data identifies available services including, but not limited to, alternate radio signals available in the vicinity, such as FM radio signals, wireless local-area network (WLAN) signals, and the like; location-related services, including the availability of location beacon signals and/or location assistance data for use in position determination using assisted-GPS technology; and physical resources available to the device user, such as printers, copy machines, vending services, and the like. An exemplary mobile station is configured to extract site-specific services data from the femtocell base station signal, and to access a second radio signal using the site-specific services data.

  • Patent number: 7650116
    Abstract: Method and device for interference cancellation. A radio access unit comprises a plurality of directionally separated antenna elements (41k, K=1, 2, . . . , L) for receiving signals transmitted by a plurality of remote units. From signals received by each of the antenna elements (41k) first weighing factors (g(1)k) are determined (49), for optimally selecting signal of a first remote unit (521). A first radio signal (s1) of the first communication unit (521) is provided by weighing (44) the received signals using the first weighing factors (g(1)k). For a further radio communication unit (52i) further weighing factors (g(i)k) are determined. A corrected further radio signal (s?i) is provided each time by subtracting (46) from the further radio signal (si), previously obtained corrected radio signal (S?i-1, S?i-1, . . . ) weighed by the further weighing factors (g(i)k), till a stop criterium has been satisfied.

  • Publication number: 20090268643
    Abstract: An entire radio transceiver can be completely integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.
