Abstract: The invention describes a method of performing re-synchronizations on a DSL line to optimize the synchronization rate of the line. The line is monitored over a period of time, and a stable SNR margin is determined, below which the line is observed to lose synchronization. Historical synchronization rates and associated SNR margins for the line are recorded, and the highest stable synchronization rate is determined as the historical synchronization rate that does not have any associated SNR margins below the stable SNR margin. The method attempts to optimize the synchronization rate of the line towards this highest stable synchronization rate. To do this, the current target SNR margin imposed by DLM is identified, for example, by interrogating the DLM system or by noting the SNR margin on the line immediately after the most recent synchronizations.

Abstract: According to some embodiments, a method of transmitting a radio signal in a first wireless network element comprises receiving, at an input of a radio transmitter, a signal for wireless transmission; selectively performing a signal linearization technique on the signal; amplifying the signal with a non-linear amplifier; and transmitting the amplified signal to a second wireless network element. According to particular embodiments, selectively performing the signal linearization technique comprises determining a modulation order of the received signal and determining the modulation order exceeds a modulation order threshold.

Abstract: A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is, Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to “ping” a UE (18).

Abstract: A method is presented for transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal by a user equipment (UE) in a wireless communication system. The UE is configured with a primary cell (PCell) and a secondary cell (SCell). The UE receives downlink control information (DCI) via a physical downlink control channel (PDCCH). The DCI including a first field for transmit power control information and a second field for ACK/NACK resource offset information. The UE receives downlink data via a physical downlink shared channel (PDSCH) based on the DCI. The UE transmits an ACK/NACK signal for the downlink data using an ACK/NACK resource. When the downlink data is received on the PCell, the ACK/NACK resource is determined by adding a lowest resource index of the PDCCH and a value of the ACK/NACK resource offset information. When the downlink data is received on the SCell, the first field includes ACK/NACK resource indication information.

Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

Abstract: An apparatus and method for a wireless device to receive data in an eco state is provided. According to an embodiment of the disclosure, upon determining that data is to be transmitted to the wireless device in the eco state, a network node operates to transmit a unicast notification message to the wireless device in order to inform the wireless device of the impending data transmission.

To this end, the wireless device might for example try to receive data for a time period following the unicast notification message. Meanwhile, the wireless device may remain in the eco state.

Abstract: A communication method is provided, which is implemented by a routing device in an information-centered communication network. The method includes the following steps to process a request relative to a data segment from a given stream, the request being routed on a link of the routing device: checking that an input bit rate for said link is higher than a threshold, the input bit rate for the link corresponding to that which is necessary for the device to receive, by using the link, a set of data segments corresponding to pending requests; and timing the request to be routed. The threshold may correspond to the bit rate available on this link at the device input, or the input bit rate may be determined for pending requests related to data segments from the given stream, and the threshold may correspond to a fair bit rate, for example.

Abstract: A technique allows stations to utilize an equal share of resources (e.g., airtime or throughput). This prevents slow stations from consuming too many resources (e.g., using up too much air time). Fairness is ensured by selective dropping after a multicast packet is converted to unicast. This prevents slow stations from using more than their share of buffer resources. Multicast conversion aware back-pressure into the network layer can be used to prevent unnecessary dropping of packets after multicast to unicast (1:n) conversion by considering duplicated transmit buffers. This technique helps achieve airtime/resource fairness among stations.

Abstract: Traffic recovery is supported at a switching node (20) of an OpenFlow network (5). The switching node (20) has a flow table (23) for storing flow entries (24) which determine forwarding of received packets between the ports.

The switching node (20) renews (104, 105) the flow entry for the backup path based on at least one of: (i) an association between the flow entry for the backup path and a flow entry for a working path at the switching node, wherein the flow entry for the backup path is renewed when the flow entry for the working path is used to forward a received packet; (ii) receiving a flow entry renewal packet from another switching node on the backup path. A backup path can be configured for each of multiple points of failure in the working path.
