  • Patent number: 10432387
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may allocate resources for communication with a user equipment (UE). The resources may include one or more subframes, and each subframe may include one or more shortened transmission time intervals (sTTIs). Each sTTI may be assigned a transmission direction according to a time division duplex (TDD) pattern. Based on traffic needs and/or interference from other UEs and/or base stations, the base station may determine to modify the TDD pattern used for communication. Accordingly, a base station may transmit an indicator in a control message or control region of a TTI or sTTI, to indicate to users that a transmission direction of an sTTI in the TDD pattern is being changed. Subsequently, a user may communicate with the base station according to the reconfigured TDD pattern.

  • Patent number: 10411912
    Abstract: Some embodiments provide a novel method for managing hardware forwarding elements (MHFEs) that facilitate the creation of multiple logical networks on a set of shared physical forwarding elements. The method uses a set of logical controllers that generate data that defines a set of logical networks, and a set physical controllers to distribute the generated data to the hardware forwarding elements. In some embodiments, each MHFE can serve as either a master WIFE or a slave MHFE for one set of computing end nodes (e.g., VMs, containers, etc.) in a logical network. To ensure proper routing of data packets to the computing end nodes, each MHFE sends to its physical controller an inventory (e.g., a table, a list, etc.) of the set of computing end nodes for which it serves as the master MHFE or the slave MHFE. Each physical controller forwards the inventory for each logical network to the logical controller for the logical network.

  • Patent number: 10390338
    Abstract: A base station device can adaptively assemble the downlink control information using a plurality of information segments and then transmit the assembled downlink control information to a mobile device. The information segments can each represent different control functions and the base station device can select relevant and appropriate information segments to include in the downlink control information based on the features represented in the downlink data transmission and the mobile device. If the downlink data transmission does not have a certain feature, the base station device can leave the information segment relevant to the feature out of the downlink control information. Additionally, when new features are introduced, new information segments can be added without defining a new downlink control information format.

  • Patent number: 10374667
    Abstract: The present invention employs a pilot scheme for frequency division multiple access (FDM) communication systems, such as single carrier FDM communication systems. A given transmit time interval will include numerous traffic symbols and two or more short pilot symbols, which are spaced apart from one another by at least one traffic symbol and will have a Fourier transform length that is less than the Fourier transform length of any given traffic symbol. Multiple transmitters will generate pilot information and modulate the pilot information onto sub-carriers of the short pilot symbols in an orthogonal manner. Each transmitter may use different sub-carriers within the time and frequency domain, which is encompassed by the short pilot symbols within the transmit time interval. Alternatively, each transmitter may uniquely encode the pilot information using a unique code division multiplexed code and modulate the encoded pilot information onto common sub-carriers of the short pilot symbols.
