  • Patent number: 10298484
    Abstract: In one embodiment, a copy of an original packet of a traffic flow is created at an ingress leaf node of a cloud switch. The ingress leaf node forwards the original packet along a less-specific path through the cloud switch, the less-specific path based on a domain index of an egress domain for the original packet. The copy of the original packet is modified to create a more specific path learn request packet. The ingress leaf node forwards the more specific path learn request packet along the less-specific path through the cloud switch. The ingress leaf node received back a more specific path learn request reply packet that includes an indication of a fabric system port. The ingress leaf node then programs a forwarding table based on the indication of the fabric system port, to have subsequent packets of the traffic flow forwarded along a more-specific path.

  • Patent number: 10257793
    Abstract: A method for use in a user terminal in a cellular communications system. According to the method, the user terminal applies a first timing advance value to its transmissions to a controlling node, and the user terminal requests communication with the controlling node in a contention based procedure by transmitting an access request (MSG 1), in response to which the controlling node transmits an initiation message (MSG 2) along with a second timing advance value. According to the method, the user terminal uses the first timing advance value if the user terminal loses the contention based procedure, i.e. if the controlling node subsequently continues the initiated communication with said other user terminal.

  • Patent number: 10257083
    Abstract: Techniques whereby a LAN-side border router observes all packets of an application flow from both directions so that the application recognition performed on the LAN-side border router functions properly. A border router may implement flags in a flow cache to indicate whether the border router is the LAN-side border router and/or a WAN-side border router for an application flow. As packets are received at a border router at either the LAN interface or WAN interface, the flags associated with packet's application flows are examined to determine if the border router is the LAN-side border router for the application flow. If so, then application recognition and routing control may be performed. If not, the packet may be redirected to another border router that may be the LAN-side border router or the WAN-side border router for the application flow to insure that border router observes the packet.

  • Patent number: 10237043
    Abstract: The present invention provides a terminal device that allows constraints on user allocation to be prevented and spread codes to be allocated in a scheduler when non-adaptive HARQ is employed using a PHICH. A codeword generator (103) generates code words (CW) by encoding data, a layer mapping unit (108) places each CW in one or a plurality of layers, a DMRS generator (110) generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs, and an ACK/NACK demodulator (102) receives a response signal indicating a retransmission request. When a response signal requesting retransmission of only a CW placed in a plurality of layers is received, the DMRS generator (110) uses each resource having the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.

  • Patent number: 10212679
    Abstract: The propagation channel in a wireless communication system may be characterized as a multipath fading model wherein the multiple delayed and attenuated versions of the transmitted signal are received. In the receiver's processing chain, the impairments introduced by this propagation channel may be equalized using the channel estimates. The channel estimation is mainly performed using the known reference signals by conventional methods. The estimation of delay spread profile may be crucial for high performance channel estimation. The conventional methods may be appropriate for high operating channel bandwidths. In the case of low channel bandwidth, limited number of reference signals may be available which may not be adequate for accurate delay spread estimation. A method and apparatus are disclosed that improve the delay spread estimation for low channel bandwidth scenarios.
