  • Patent number: 10314013
    Abstract: The present invention relates to wireless communications technologies, and in particular, to a terminal, a network device, and a data transmission method in a random access process, so as to resolve a current problem that a transmission delay is relatively long when a terminal transmits a relatively large data packet in a random access process. In the terminal a processing module, is configured to determine that the terminal transmits data of multiple TTIs to a base station in a current random access process; and a transceiver module is configured to send first indication information to the base station, where the first indication information is used to indicate that the terminal transmits the data of the multiple TTIs in the current random access process. In this way, the terminal can transmit data of multiple TTIs in one random access process.

  • Patent number: 10257005
    Abstract: An apparatus includes circuitry that processes a subframe as part of a time-domain signal frame structure used for radio frequency communications. The subframe includes a plurality of block symbols each having an associated time-domain guard period and one or more radio frequency (RF) switching guard periods. Each block symbol of the plurality of block symbols is either a common block symbol or a special block symbol. A common block symbol has a common time-domain guard period with all other common block symbols of the subframe. A special block symbol has a time-domain guard period different from the common time-domain guard period. All the special block symbols in the subframe are placed into the one or more RF switching guard periods.

  • Patent number: 10257793
    Abstract: A method for use in a user terminal in a cellular communications system. According to the method, the user terminal applies a first timing advance value to its transmissions to a controlling node, and the user terminal requests communication with the controlling node in a contention based procedure by transmitting an access request (MSG 1), in response to which the controlling node transmits an initiation message (MSG 2) along with a second timing advance value. According to the method, the user terminal uses the first timing advance value if the user terminal loses the contention based procedure, i.e. if the controlling node subsequently continues the initiated communication with said other user terminal.

    Abstract: Methods, systems, and devices are described for wireless communication. A device may use enhanced reporting mechanisms to support control information reporting on shared spectrum. In some cases, a device may utilize enhanced component carriers (eCCs) for data transmissions. In one example, the device may transmit control information (e.g., ACK/NACK, CSI, etc.) to a corresponding device using a CCA exempt transmission (CET). In another example, a device may report control information quasi-periodically. For instance, a device may be assigned a specified interval and a control feedback window for reporting control information (e.g., CSI). The window may provide a duration prior and subsequent to the specified interval during which a UE may transmit control information. For example, the device may perform a CCA reserving the channel for a duration that does not include the specified interval but may transmit feedback information based on determining the specified interval falls within the assigned window.

    Abstract: In one aspect of the teachings herein, a wireless device operating in a multi-connectivity configuration with respect to an associated wireless communication network applies asymmetrical blanking to two or more of its multi-connectivity connections in conjunction with acquiring system information for a target cell during one or more measurement gaps. “Blanking” as used here implies an interruption in downlink reception, or an interruption in uplink transmission, or both, and arises as a consequence of the measurement gaps used by a wireless device to make measurements on target-cell signals. Asymmetrical blanking results in, for example, the wireless device sending more or less acknowledgment/non-acknowledgment, ACK/NACK, signaling on one of the connections relative to another one of the connections, when acquiring the target-cell system information.

    Abstract: A method and system for facilitating communication between an Evolved Node B (eNB) and a user equipment (UE) in a Long Term Evolution (LTE) network. In particular the technology addresses downlink transmission via potentially large TTI bundles. The eNB transmits a downlink grant message to the UE, indicating a pending TTI bundle for downlink transmission. The UE transmits an acknowledgement message to the eNB if the DL grant message is successfully received and decoded. The eNB aborts transmission of the TTI bundle if it fails to timely receive the acknowledgement and may reassign the network resources scheduled for use in the transmission. In some embodiments, the eNB may introduce a delay between the downlink grant message and the TTI bundle.

  • Patent number: 9430645
    Abstract: An event retrieval and analysis system compares counts of event data for a device to stored profile counts to determine if alerts should be triggered. Event data can be retrieved by a sensor. Rules for analyzing the event data can be retrieved based on the device. The event data is analyzed based on the rules to determine recordable events. Recordable events are organized into categories representing a type or severity of attack. Current event counts are calculated by summing the recordable events for each category. A normal profile is retrieved for the device and compared to the current event count. A percentage change trigger can be retrieved from a threshold matrix based on the current event count. The percentage increase of the current event count over the normal profile is calculated and compared to the percentage change trigger to determine if an alert is triggered by the analysis system.

  • Patent number: 9426522
    Abstract: The disclosure relates to techniques for switching between channels of digital multimedia content. In particular, a decoding device decodes and renders to a display at least one frame of a segment of data prior to receiving the entire segment. In certain aspects, the decoding device may render one of the frames of the segment and freeze the rendered frame until the decoding device receives all of the frames of the segment. In other aspects, the decoding device may render frames of one or more segments at a reduced rendering rate until the receiving and rendering operations of decoding device are synchronized such that the rendering of the current segment occurs at substantially the same time as the receiving of the next segment. By rendering at least frame prior to receiving the entire segment the decoding device more quickly displays content to a user during a channel switching event.

  • Patent number: 9271289
    Abstract: A switching control module can optimize time division duplexing operations of a distributed antenna system (“DAS”). The switching control module can include a measurement receiver and a processor. The measurement receiver can measure signal powers of downlink signals in a downlink path of the DAS. The processor can determine start times for downlink sub-frames transmitted via the downlink path based on downlink signal powers measured by the measurement receiver exceeding a threshold signal power. The processor can identify a clock setting that controls a timing of switching signals used for switching the DAS between an uplink mode and a downlink mode. The processor can statistically determine a switching time adjustment for the clock setting based on switching time differentials between the clock setting and the start times. The processor can update the clock setting based on the switching time adjustment.
