  • Patent number: 10367677
    Abstract: Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

  • Publication number: 20190097673
    Abstract: There is provided mechanisms performed by a control device for suppressing interference in a received reception signal in a radio transceiver device. The radio transceiver device is configured to receive the reception signal as a radio reception signal and to generate a radio transmission signal. The radio transmission signal and the radio reception signal occupy at least partly non-overlapping frequency bands. A method comprises obtaining a transmission reference signal based on the radio transmission signal. The method comprises estimating an interference distortion component signal based on the transmission reference signal and on a model of nonlinearity in a radio circuit of the radio transceiver device. The method comprises suppressing interference in the reception signal by combining the reception signal with the distortion component signal.

  • Patent number: 6732922
    Abstract: A system for Internet Enablement of automatic fare collection devices, such as smart cards, interfaces to smart card fare systems to increase the ability to sell and process transit payments and to collect entry permits or tickets at an access device or fare collection equipment. The system comprises a server containing a database for storing accounts of individual cardholders where each smart card is associated with a unique account. A patron or cardholder accesses his account via a terminal containing a web browser to purchase entry permits. Once the entry permits have been purchased, the cardholder presents his card to an access device which communicates with the server to determine if there are any pending entry permits. If there are any pending entry permits associated with the access device, the entry permit is written to the smart card and the other entry permits remain pending until the cardholder presents the card at the appropriate access device.
