  • Patent number: 9549408
    Abstract: The present disclosure concerns interference congestion control in radio communication networks. Disclosed herein are methods as well radio network nodes. A radio network node may, for example, estimate a neighboring cell interference. The radio network node may also detect a sudden significant increase in the estimated neighboring cell interference. In response to detecting a sudden significant in the estimated neighboring cell interference, the radio network node may also transmit a message to at least one other radio network node. This message may include an indicator indicating to said at least one radio network node to initiate an interference congestion control procedure. Hereby it is made possible to allow for interference congestion control in radio communication networks.

  • Patent number: 9548837
    Abstract: A method for transmitting and receiving a source data block using hybrid automatic retransmission request protocol. At the transmitting side, the source data block that is not decoded correctly at the receiving side is divided into a plurality of data segments, each of which may be padded with known data to expand the data segments to be a predetermined lengthen. At the receiving side, when each of the received data packets includes a data segment and a redundancy information segment, decoding is performed based on the received data segment and redundancy information segment extracted from buffered data packets, with chances to restore the data segment that is not decoded correctly in previous decoding processing. The additional decoding chances improve the probability of correctly decoding the erroneous data segment.

  • Patent number: 9549396
    Abstract: A method and user equipment (UE) for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. The UE determines a Physical Uplink Control Channel (PUCCH) format and a PUCCH resource through which ACK/NACK information for downlink transmission in a downlink subframe set including M (M>1) downlink subframes is to be transmitted. The UE transmits the ACK/NACK information using the PUCCH format and the PUCCH resource in one uplink subframe. More than one serving cell is configured for the UE and the more than one serving cell includes one Primary Cell (PCell) and at least one Secondary Cell (SCell). The ACK/NACK information is transmitted using a PUCCH format 1b, when the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set.

  • Patent number: 9541938
    Abstract: This invention relates to a network architecture for data communication between data sources and data destinations via network nodes and at least one data concentrator. According to the invention the nodes (2, 4) are conceived to communicate with a data concentrator (1) in both directions either via a permanently operative network (8) in the multihop mode or via an occasionally operative network (5) in wireless connection with mobile user nodes (6) in the nomadic mode. Means for commutation are provided to detect faulty multihop nodes and to activate nomadic nodes instead until the fault disappears, in order to maintain the overall functionality of the network. Moreover the network according to the invention allows the data collected by mobile users to be shared with other mobile users, thus forming a peer-to-peer network.

  • Patent number: 9391948
    Abstract: A method of discovering and assigning an IP address to a device to be discovered in a communication network having multiple interconnected nodes includes continuously monitoring, by the device to be discovered, the network for address resolution protocol (ARP) requests. The discoverer node transmits a number of ARP request to the network. The device to be discovered receives the number of ARP requests. The device to be discovered determines whether the number of ARP requests are unanswered by other devices in the network. The device to be discovered answers to the number of ARP requests with an ARP reply to claim an IP address associated with the number of ARP requests. The discoverer node and the device to be discovered exchange a pair of User Datagram Protocol (UDP) packets to complete the detection process.

  • Patent number: 9369978
    Abstract: A mobile device receives a signal, from a base station, comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device utilizes two different sampling rates to perform the PSS synchronization and the SSS detection individually. For example, the mobile device synchronizes to the received PSS at a first sampling rate such as 0.96 MHz, which is determined based on the PSS transmission rate and/or the length of the received PSS. The mobile device detects the received SSS at a second sampling rate such as 1.92 MHz, which equals to the sampling rate for an analog-to-digital conversion at the mobile device. The received PSS and associated symbol timing are detected through the PSS synchronization to support the SSS detection. The detected SSS is used to acquire cell-specific parameters such as cell ID. The acquired cell-specific parameters ensure proper communications between the mobile device and the base station.

  • Patent number: 9345032
    Abstract: Practical methods and apparatuses are provided for determining network clusters in wireless backhaul networks comprising a plurality of hubs (102) and Remote Backhaul Modules (RBM) (104) based on link quality value (LQV) metrics. From an input LQV table of LQV values for each hub-RBM link (110), the link quality values are first ranked. Clusters are then identified from all the possible links based on the order of the highest link quality value to the lowest link quality value, any constraints on the number of RBMs per cluster, and clustering each RBM only once. Links with strong link quality values are chosen to optimize the LQV metric. LQV based clustering achieves a higher average LQV, e.g., average spectrum efficiency or weighted sum spectrum efficiency, for the entire backhaul network compared to the geographic location based clustering. The method is straightforward to implement and has low computational complexity.

  • Patent number: 9319194
    Abstract: A wireless device receives message(s) configuring cell groups and transmissions of sounding reference signals (SRSs). Uplink transmission timing in a first cell group is derived employing a cell in the first cell group and uplink transmission timing in a second cell group is derived employing a second cell in the second cell group. A first signal is transmitted on a cell of the first cell group. A first subset of the SRSs are dropped and a second subset of the SRSs are transmitted if transmission of SRSs overlap in time with transmission of the first signal and a calculated total transmission power exceeds a first power value.

  • Patent number: 9313128
    Abstract: In a flow-based network such as an open flow network system, even when a network appliance such as NAT and NAPT for translating a packet header is passed through, a correspondence relation of two flows before and after the passing can be grasped to make it possible to trace the flow in end-to-end. Specifically, a packet is encapsulated in a switch (or in a controller requested from the switch). By encapsulating by using the same header as a current header, two kinds of headers before the translation and after the translation are attached to the packet after the packet phases through the network appliance.
