    Abstract: The present invention discloses a method and an apparatus for primary synchronization signal (PSS) detection. The method may comprise: performing a central-symmetrical preprocess on a receive vector by exploiting a central symmetry of the primary synchronization signal; and performing, based on the central-symmetrical preprocess, a non-coherent detection on the receive vector using local primary synchronization signals so as to detect the primary synchronization signal. The computation complexity in PSS detection may be significantly reduced by performing preprocess to the receive vector based on the central symmetry of the primary synchronization signal, thereby considerably enhancing the speed and performance of PSS search and further improving the cell search efficiency.

  • Patent number: 9204379
    Abstract: Techniques for sending sector/system information in TDM pilots using a hierarchical pilot structure are described. A base station sends multiple sets of bits for the sector/system information in multiple TDM pilots. The set of bits sent in a given TDM pilot may include bits sent in earlier TDM pilots. In one design, the base station generates a first TDM pilot based on a first set of bits, generates a second TDM pilot based on a second set of bits that includes the first set, generates a third TDM pilot based on all bits for the information, and sends the TDM pilots. A terminal performs detection to obtain a first detected value for the first TDM pilot, performs detection based on the first detected value to obtain a second detected value for the second TDM pilot, and performs detection based on the first and second detected values to obtain a third detected value for the third TDM pilot.

  • Patent number: 9197369
    Abstract: In a network that provides high-speed packet access, a mobile terminal is served by multiple activated serving cells which are grouped into cell groups. The mobile terminal monitors control channel transmissions to detect whether there are any transmissions for the mobile terminal from the activated serving cells for each cell group and provides feedback to a primary serving cell. When no transmission is detected from serving cells of a particular cell group, the mobile terminal may transmit feedback information explicitly indicating that no transmission is detected for that cell group. Alternatively, the mobile terminal may withhold transmitting feedback for that cell group and increases the power for transmitting the feedback information for cell groups in which transmissions were detected.

  • Patent number: 9137054
    Abstract: In an embodiment, a transmitter includes a transmission path that is configurable to generate first pilot clusters each including a respective first pilot subsymbol in a first cluster position and a respective second pilot subsymbol in a second cluster position such that a vector formed by the first pilot subsymbols is orthogonal to a vector formed by the second pilot subsymbols. For example, where such a transmitter transmits simultaneous orthogonal-frequency-division-multiplexed (OFDM) signals (e.g., MIMO-OFDM signals) over respective channels that may impart inter-carrier interference (ICI) to the signals due to Doppler spread, the pattern of the pilot symbols that compose the pilot clusters may allow a receiver of these signals to estimate the responses of these channels more accurately than conventional receivers.

  • Patent number: 9129603
    Abstract: A foolproof method of adding network-enabled energy control devices to a home energy device control network by associating an easy-to-remember catchphrase composed of ordinary words with a unique MAC address or EUI identifier of the network-enabled device. The device manufacturer associates a unique catchphrase with each device and stores the catchphrases and associated MAC addresses in a database along with the device information required to commission the device onto the user's network. When the user enters the catchphrase, the catchphrase is sent to the manufacturer's server for retrieving the MAC address and corresponding device information. When a valid catchphrase is entered and accepted, the device can be commissioned onto the user's network.

  • Patent number: 9119163
    Abstract: Methods and apparatus related to the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. A base station transmits a signal to be used by a peer to peer wireless terminal in controlling its peer to peer transmit power level. The peer to peer wireless terminal receives and measures the strength of the base station signal. The measurement information is used in determining whether or not peer to peer signal transmission is permitted and/or in determining a peer to peer transmission power level. Current service level information and/or encoded information, e.g., an interference level indicator value, conveyed by the received base station signal are, in various embodiments, also utilized in determining a peer to peer transmission power level.

  • Patent number: 9094840
    Abstract: A test system may include test equipment for testing the radio-frequency performance of wireless electronic devices. The test equipment may provide radio-frequency downlink signals to a wireless electronic device under test (DUT). The test equipment may perform a power sweep by stepping down the downlink signals in signal power level to test receiver sensitivity for the DUT. The DUT may gather measurement data from the downlink signals. The test equipment may retrieve measurement data from the DUT after downlink signal transmission has ended. The test equipment may identify a trigger in the retrieved measurement data to ensure that the data is synchronized with the power sweep in the transmitted downlink signals. The test equipment may identify path loss information associated with the test system. The test equipment may compute receiver sensitivity values for the DUT based on the path loss information and retrieved measurement data.

  • Publication number: 20150124856
    Abstract: A method for soft frame synchronization in a navigational receiver is provided. A distance between bits of a sync pattern received by the navigational receiver and a known sync pattern is computed. A probability of detection value for the received sync pattern based on the distance is assigned. A confidence level for the received sync pattern using the probability of detection value is computed. The confidence level is compared with a confidence threshold. If the confidence level is greater than or equal to the confidence threshold, the confidence level of the received sync pattern is updated to generate a credibility of the sync pattern. The credibility of the received sync pattern is compared with a predetermined credibility value and, if the credibility of the received sync pattern is greater than or equal to the predetermined credibility value, synchronization of the navigational receiver is performed using the received sync pattern.
