  • Patent number: 9667385
    Abstract: Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. At the time of channel selection, a control unit (208) selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station (100) and PUCCH resources mapped to a CCE, and controls the transmission of the response signal. A response signal generating unit (212) supports implicit signaling with respect to any given response signal, and at the same time as supporting LTE fallback from 2CC, uses a mapping method that, between bits, smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

  • Patent number: 9641371
    Abstract: Disclosed herein are methods and systems for dynamic single-frequency-network-(SFN)-multicast symbol synchronization. In an embodiment, a wireless-communication device (WCD) receives an SFN-multicast transmission at least in part by receiving a respective SFN-multicast-transmission signal from each site in a plurality of sites in a given SFN-multicast area, where each such received SFN-multicast-transmission signal has a respective SFN-multicast cyclic prefix. The WCD calculates a multisource multipath delay spread (“MMDS”) that is characteristic of the received plurality of SFN-multicast-transmission signals, and determines whether that calculated MMDS exceeds a threshold MMDS. If so, the WCD selects a multicast timing point that is after the SFN-multicast cyclic prefix of a first-received one of the received SFN-multicast-transmission signals. If not, the WCD selects a multicast timing point that is within the SFN-multicast cyclic prefix of the first-received SFN-multicast-transmission signal.

  • Patent number: 9526080
    Abstract: An in-vivo device may allocate a sensing window in a work cycle for sensing and processing localization signals to determine the location/orientation of the in-vivo device. The in-vivo device may use a timing unit to schedule transmission of data frames and the sensing of the localization signals relative to a reference time embedded in work cycles. The timing unit may produce a clock signal based on which the in-vivo device may measure time specifics, which define the sensing window, relative to the reference time. A receiver may use data embedded in data frames to restore the clock signal and the reference time, and, from them, and using identical or similar time specifics, generate a synchronization signal for a localization signals source (LSS) to enable the LSS to generate localization signals in synchronization with the sensing windows.
