Abstract: A device includes a master control card that performs control plane processing, a backup control card, where the backup control card takes over control plane processing if the master control card goes out of service, and a database card that connects to the master control card and the backup control card, where the database control card stores information relating to control plane processing. A method of achieving hitless failover in a network element includes detecting that a master control card of the network element has gone out of service, designating the backup control card as a new master control card of the network element, establishing communication with a database card of the network element, and retrieving protocol states information from the database card.

Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—?F_PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.

Abstract: A system and method for data conversion includes a transmitter configured to receive high-speed data and convert it into wireless low-speed data for output to a receiver. The transmitter includes a radio device and one or more processors for converting the high-speed data to low-speed data. Once received by the receiver, the low-speed data may be output for use directly by equipment which uses such data, or it may be reconverted to high-speed data and output to equipment that utilizes high-speed data signals.
Abstract: A window regulator for improving the performance of communications networks is described. In a communications network, data is sent downstream from a sender to a receiver, and acknowledgements are sent back upstream. When data is received at the receiver, the data is placed in a buffer and an acknowledgement of receipt may be sent. If no acknowledgement is received by a sender after a certain period of time, the sender retransmits the data. The receiver communicates how much data the receiver is willing to receive at any given time by sending an advertised window to the sender. The window regulator sets the size of the advertised window based on measurements of capacity in the network to improve the amount and rate of data sent downstream while avoiding loss of data and subsequent retransmissions.
Abstract: A method is provided in one example and includes receiving a request to initiate a communication flow associated with a subscriber and identifying one or more parameters to be monitored for the communication flow. The method further includes extracting one or more bits from packets associated with the communication flow; the bits are used to determine an operating system associated with the communication flow. A policy decision can be executed for the communication flow based on the operating system associated with the communication flow. In more specific examples, the bits are sent to a next destination in response to a threshold being reached for at least one of the parameters. The parameters can be associated a volume parameter or a time parameter. The policy decision could include blocking traffic associated with the subscriber, initiating billing, redirecting the communication, managing a quality of service level for the communication flow, etc.

Abstract: In a method for improving the transmission efficiency in a communication system with a layered protocol stack, data packets are processed on an upper protocol layer. Data packets are forwarded to a lower protocol layer for transmission and the transmission is performed with variable channel access delays. The upper protocol layer is notified by the lower protocol layer when a transmission is started to allow a synchronization of timers in the upper protocol layer. If a layer performs a scheduling of data packets for the transmission, a rescheduling is performed alternatively or in addition during a channel access delay. Devices and software programs embodying the invention are also described.

Abstract: A node in a wireless communication system includes a transceiver that operates according to a first radio access technology (RAT). The transceiver is to measure a medium usage by one or more other nodes that operate according to a second RAT. The transceiver alternately transmits in a first time interval and bypasses transmission in a second time interval. The first and second time intervals repeat with a duty cycle. The transceiver is to puncture the first time interval with one or more silent gaps. The node also includes a processor to determine a duration of the one or more silent gaps is based on the medium usage.

Abstract: The present disclosure encompasses establishing and maintaining a routing protocol based on a measured link metric p, such as for a smart grid communication system. A link between a first node such as a router A and a neighbouring second node B of a communication path from a source to a destination in a packet oriented communication network is selected wherein the two nodes are connected via first and second communication links. An updated link metric p(t+1) at a point in time t+1 of the first communication link is determined. The first or the second communication link is selected for transmitting a further packet from node A to node B by comparing the updated link metric p(t+1) to a threshold pthr.
Abstract: Methods and apparatus for sounding reference signals (SRS) configuration and transmission. The methods include receiving configuration of wireless transmit/receive unit (WTRU)-specific SRS subframes for transmitting SRS and upon receipt of a trigger, transmitting the SRS for a number of antennas. The SRS transmissions may occur in each subframe of a duration of WTRU-specific SRS subframes that start a number of WTRU-specific SRS subframes after a triggering subframe. For multiple SRS transmissions from multiple antennas, cyclic shift multiplexing and different transmission combs may be used. The cyclic shift for an antenna may be determined from a cyclic shift reference value. The cyclic shift determined for each antenna providing a maximum distance between cyclic shifts for the antennas transmitting SRS in a same WTRU-specific subframe. SRS transmissions from multiple antennas in the WTRU-specific subframe may be done in parallel.

It is thus for example possible to enable a single radio terminal to establish radio connections with cells of a plurality of radio stations, in order to achieve carrier aggregation of cells operated by different radio stations.
