  • METHOD AND INTERFACE FOR INTERFACING A RADIO FREQUENCY TRANSCEIVER WITH A BASEBAND PROCESSOR
    Publication number: 20130089012
    Abstract: An interface includes three sub-interfaces. A first and second sub-interface receive first/second inbound IQ data streams, respectively, packetize the first/second inbound IQ data streams to obtain first/second inbound IQ data packets, respectively, and transmit the first/second inbound IQ data packets to the baseband processor via a first/second set of RX lanes, respectively. Each first/second inbound IQ data packet comprises a data packet identifier out of a common set of possible data packet identifiers. A third sub-interface receives outbound IQ data packets from the baseband processor via a TX lane, and depacketizes the outbound IQ data packets to obtain an outbound IQ data stream. The third sub-interface receives an RX not-acknowledge signal via the TX lane that identifies a defective first or second inbound IQ data packet within the first/second inbound IQ data packets.

  • LTE operation in white spaces
    Patent number: 8406780
    Abstract: One embodiment of the present invention relates to a method for efficient reassignment of a secondary communication channel (having a first priority) within a white space, upon arrival of a conflicting primary user signal (having a second priority higher than the first priority). In particular, the method comprises reassigning a secondary communication channel to unused portions of one or more white spaces remaining after the arrival of one or more primary users. For example, in one embodiment wherein one or more secondary communication channels are operated at contiguous secondary frequency ranges within a white space, a primary/incumbent user may arrive at a frequency range that conflicts with the secondary frequency range and that generates unused frequency portions of the white space(s). The secondary communication channel may be reassigned to the unused frequency portions of the white space (e.g.
