  • Patent number: 10306576
    Abstract: This closure relates to narrowband communication supporting an Internet of Things (IoT) service in a next-generation wireless communication system and, more particularly, to a method and apparatus for transmitting and receiving narrowband synchronization signals. A base station repeats a Zadoff-Chu sequence on each of multiple OFDM symbols; multiplies each component of a cover sequence, having a length corresponding to a number of the multiple OFDM symbols, to all the components of the Zadoff-Chu sequence on each of the multiple OFDM symbols. Then, the base station transmits the NB PSS by using the Zadoff-Chu sequence multiplied by the cover sequence to the one or more UEs.

  • Patent number: 10298417
    Abstract: Methods and systems for obtaining improved channel estimates for frequency-multiplexed data transmissions such as OFDM, OFDMA, or SC-FDMA transmissions overcome the limitations of the static assumption by using a polynomial or other fitting function to fit and model the frequency dependence of the channel coefficients, so that estimates can be applied to larger subcarrier groups. Some embodiments provide channel estimates for a singular signal source, while other embodiments provide joint channel estimates for a plurality of signal sources. In embodiments, selection of the fitting functions is influenced by all previously determined channel estimates. In some embodiments, a tracking algorithm allows use of the lowest possible order of polynomial or other fitting function to model the frequency dependence of the channel coefficients, whereby the channel estimate is continually shifted in frequency while the order of the polynomial or other fitting function remains low.

  • Patent number: 10289504
    Abstract: An access control method and system and an access point. When a fault occurs in an access controller (AC), an access point (AP) configures a network-layer interface of the AP according to an Internet Protocol (IP) address and a media access control (MAC) address of the AC that are obtained by means of pre-learning, and then the AP routes a received packet to a Web server on a wireless local area network (WLAN) using the configured network-layer interface, where the packet is used by a first station (STA) to request to access an external server. Therefore, interconnection and interworking among wireless local area networks are implemented, and a breakdown of a wireless local area network caused in a centralized network architecture due to occurrence of a fault in an AC is avoided.

  • Patent number: 10270606
    Abstract: In one embodiment, a device in a network sends a first multicast message to a plurality of destinations in the network. The first multicast message includes a first bitmap that identifies the destinations. The device receives one or more acknowledgements from a subset of the destinations. The device determines a retransmission bitmap that identifies those of the plurality of destinations that did not acknowledge the first multicast message, based on the received one or more acknowledgements. The device sends a retransmission multicast message to those of the plurality of destinations that did not acknowledge the first multicast message. The retransmission multicast message includes the retransmission bitmap.

  • Patent number: 10264482
    Abstract: When a UE in an LTE system enters the RRC_IDLE state, only the S5/S8 EPS bearer context is retained, and the S1-U, S1-AP and radio bearers are released. These bearers have to be re-established on per UE basis when the UE returns to RRC_CONNECTED state. A number of UE applications may send small data frequently, which causes the UE to toggle between IDLE and CONNECTED states. This leads to a great deal of signaling overhead as the radio bearer and the S1-U bearer must be frequently re-established as the UE transitions between IDLE to CONNECTED states. Described herein are methods and systems that provide an always-on S1-U bearer to reduce this signaling overhead.

  • Patent number: 10243884
    Abstract: The present disclosure provides a packet transmission method and an apparatus. A first network device receives, through an inter-system cascade port, a first packet sent by a second network device, and adds a first remote RMT identifier to the first packet to obtain a second packet; d the first network device determines, according to the first RMT identifier in the second packet and an attribute of a sending port for the second packet, whether there is a need to perform pruning processing on the second packet; and if the sending port for the second packet is a multi-homed port, the first network device performs pruning processing on the second packet; if the sending port for the second packet is a single-homed port, the first network device deletes the first RMT identifier in the second packet, and sends the first packet through the single-homed port.

  • Patent number: 10230607
    Abstract: System and method for supporting intra- and inter-subnet address resolution in a network environment using the same linear forwarding tale (LFT) for both the intra- and inter-subnet forwarding. Subnet prefix values in global route headers (GRHs) are used for linear forwarding table (LFT) lookup in a high performance computing environments. An exemplary can provide for use of an Inter Subnet Route Number (ISRN) embedded in the subnet prefix values in the GRHs for LFT lookup in a network switch environment in a high performance computing environment such as a network having an InfiniBand (IB) architecture. A method can provide, at a computer environment, including a network fabric, one or more subnets, each of which subnets are associated with one or more network switches or hosts.

  • Patent number: 10230665
    Abstract: Methods, apparatus, and systems for implementing hierarchical and lossless packet preemption and interleaving to reduce latency jitter in flow-controller packet-based networks. Fabric packets are divided into a plurality of data units, with data units for different fabric packets buffered in separate buffers. Data units are pulled from the buffers and added to a transmit stream in which groups of data units are interleaved. Upon receipt by a receiver, the groups of data units are separated out and buffered in separate buffers under which data units for the same fabric packets are grouped together. In one aspect, each buffer is associated with a respective virtual lane (VL), and the fabric packets are effectively transferred over fabric links using virtual lanes. VLs may have different levels of priority under which data units for fabric packets in higher-priority VLs may preempt fabric packets in lower-priority VLs.

  • Patent number: 10104689
    Abstract: A first wireless device determines the duration of a clear channel assessment interval based on feedback signals before transmitting data to a second wireless device. The first wireless device receives feedback signals, such as acknowledgement (ACK) and negative acknowledgement (NAK) signals, from one or more second wireless devices. The first wireless device determines a ratio of NAK/ACK signals in the feedback signals for a predetermined amount of time. The first wireless device determines whether the wireless medium is free by monitoring for wireless signals during a clear channel assessment interval. The duration of the clear channel assessment interval is based on the ratio of NAK/ACK signals. If the wireless medium is free for the duration of the clear channel assessment, the first wireless device wirelessly transmits data to at least one of the second wireless devices.
