  • Patent number: 9042337
    Abstract: A method and system for minimizing the control overhead in a multi-carrier wireless communication network that utilizes a time-frequency resource is disclosed. In some embodiments, one or more zones in the time-frequency resource are designated for particular applications, such as a zone dedicated for voice-over-IP (VoIP) applications. By grouping applications of a similar type together within a zone, a reduction in the number of bits necessary for mapping a packet stream to a portion of the time-frequency resource can be achieved. In some embodiments, modular coding schemes associated with the packet streams may be selected that further reduce the amount of necessary control information. In some embodiments, packets may be classified for transmission in accordance with application type, QoS parameters, and other properties. In some embodiments, improved control messages may be constructed to facilitate the control process and minimize associated overhead.

  • Patent number: 9019963
    Abstract: Frame contained destination information may be used by a switch to identify an appropriate output port for a given frame without performing a table access operation. This reduces the processing requirements of the switch to enable the switch to handle frames more efficiently. The frame contained destination information may be contained in the frame's local destination MAC addresses (DA) such that a portion of the DA directly indicates, for each switch that handles the frame, an output port for that switch. Different portions of the DA may be used by different switches, depending on where they are in the network hierarchy. Large switches may also use sub-fields within their allocated portion in the DA to identify internal switching components. A location resolution server may be provided to store and distribute IP and MAC addresses and respond to local ARP requests on the local domain.

  • Patent number: 9001807
    Abstract: A signal encoding method and device and a method for encoding a joint feedback signal are provided. When two carriers are configured with multiple-input and multiple-output (MIMO), Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) signals of the two carriers are combined into a joint feedback signal. The joint feedback signal is mapped into a codeword according to predetermined mapping relationship between signals and codewords. Therefore, through the method for combining and encoding feedback signals of two carriers for transmission on a code channel in a dual cell (DC)-MIMO mode, bit error ratio (BER) and detection error cost are decreased, power overhead is saved, and a cubic metric (CM) value of the system is not affected, thereby enhancing the performance of the system.

  • Patent number: 8982698
    Abstract: A transmission method is used by a node of a communications network, wherein nodes communicate with one another via a carrier-sense multiple-access channel, said method comprising a step of sending a signal at a given transmit power and a given data rate to a receiver node over the channel, and wherein the transmit power of the sent signal assumes successively a first power value during a first time period and then a second power value during a second time period, the two power values being different and one of them being equal to the given power, the first time period representing the given power and the second time period representing the data rate. The invention also relates to a method of receiving a signal sent by the transmission method enabling the transmit power and the data rate used by the sender node to be deduced from the received signal.

  • Patent number: 8971300
    Abstract: Systems and methods for providing network access to mobile devices that travel with a vehicle, such as a train, a bus, a boat, etc. along or adjacent to a relatively fixed path that may extend over a large geographic area. Mobile devices access the network through stationary access points arranged along or adjacent to the path and communicate with a communication network. The communication network may be arranged as an asynchronous transfer mode (ATM) local area network emulation (LANE) network. One of the mobile devices may be a mobile access point which can couple other mobile devices to the network and record authentication information of other mobile devices so that fast transitions can be made from one stationary access point to another as the vehicle moves along the path.
