  • Publication number: 20130003677
    Abstract: A method for transmitting Common Public Radio Interface (CPRI) data in a radio base station is provided, which is applicable to the radio base station having at least two CPRI links between a Radio Equipment Control (REC) and a Radio Equipment (RE). The method includes: dividing by the REC, in-phase/quadrature phase (I/Q) data that needs to be transmitted to the RE into multiple paths of I/Q data with different content, where the multiple paths of I/Q data with different content make up the I/Q data before being divided; transmitting, by the REC, all paths of divided I/Q data to the RE over the at least two CPRI links.

  • Patent number: 8275418
    Abstract: A base station device includes radio equipment (RE) having a first port and a second port, a first radio equipment controller (REC) supporting a first radio access technology, and a second REC supporting a second radio access technology. The first REC is configured to transmit first downlink data corresponding to the first radio access technology to the RE, and to receive first uplink data corresponding to the first radio access technology from the RE. The second REC is configured to transmit second downlink data corresponding to the second radio access technology to the RE, and to receive second uplink data corresponding to the second radio access technology from the RE.

  • Patent number: 8062901
    Abstract: The present invention provides devices, methods, and kits for the collection of a solid or semi-solid sample and analysis for the presence, absence, or quantity of an analyte. The invention provides a collection slide having a first card and a second card. The first card has a sample collection area. The first and second cards have orifices allowing the passage of fluid through the sample collection area, and the cards are hingeably connected to each other. The invention also provides an assay device having a housing with a test element, a results window, and a docking area for receiving and engaging the collection slide. In one embodiment the collection slide and device can be used to detect the presence of fecal occult blood (human hemoglobin) in a stool sample. Many other embodiments are described herein.
