  • Terminal device, base station device, retransmission method, and resource allocation method
    Patent number: 9730188
    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.

  • Traffic distribution over multiple paths in a network while maintaining flow affinity
    Patent number: 9716592
    Abstract: System and methods for efficiently distributing data packets in a multi-path network while maintaining flow affinity are provided. In one aspect, a system and method includes calculating hash values for distributing different flows, or sets of flows, of data packets received at a routing device. The hash value is calculated not only using information in the data packets, but also based on additional information that is determined based on an N-bit derived from the data packets. In some cases, calculating a hash value based on the additional information increases the entropy of the hashing function, thus enabling a routing device to distribute different flows of data packets over a greater number of network paths. Each routing device can derive a different, and randomly generated N-bit key while maintaining flow affinity for each received data packet in a given flow of data packets.
