Abstract: Embodiments described herein provide apparatus and methods for performing HARQ operations using parallel HARQ threads, where each new transmission of a Media Access Control (MAC) Protocol Data Unit (MPDU)/Aggregate-MPDU (A-MPDU)/Physical Layer Convergence Procedure (PLCP) Service Data Unit (PSDU) triggers the activation of a HARQ thread. Each HARQ thread contains one or more HARQ coding words or coding units. A HARQ thread index is setup by a transmission opportunity (TXOP) holder for a corresponding PSDU and is used to identify HARQ threads. Transmission information such as duration in formation for PPDUs including BA/HARQ-ACK feedback such as RX/TX addresses, etc. can be determined according to previous transmission values of a received PPDU (e.g., values of a MAC or PHY header).

Abstract: Disclosed are a method and apparatus for high-speed processing of GTP-U packets in a mobile network. The packet processing method and the apparatus according to an embodiment implements the encapsulation or decapsulation of GTP-U packets in a mobile network in a hardware-based structure to process the LBO of the GTP-U packet at high speed. It achieves the processing and solves the difficulty of protocol interworking with the mobile core network as information for the encapsulation or decapsulation processing of the GTP-U packet independently is acquired through self-learning without the help of the mobile core network.

Abstract: Described herein are systems and methods providing a multi-dimensional ring-lattice network topology. Systems and methods disclosed herein provide for constructing network topologies in a form of a partial mesh (a partially connected network), where a bridge is capable of forwarding packets through other bridges when a direct link to the destination compute device is not available. A temporary on-demand tunnel is created by virtual networking software on-demand, to facilitate a direct tunnel between two virtual network interfaces where such a direct connection is not available with a permanent tunnel, and where there is sufficient traffic demand between these two interfaces that justifies a direct tunnel. The described approach provides a framework for achieving a compromise between link count limitation, and packet-forwarding path length, that can be tailored to address particular network requirements, together with a way to reliably predict the performance of the resulting network.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) burst set patterns in which SSs and broadcast channel transmissions may be transmitted (e.g., in time). A base station may identify a SS burst set pattern indicating positions (e.g., time locations) for SS block transmissions, for example, in bandwidth restricted communication systems. The SS burst set pattern may be determined based on numerology or subcarrier spacing associated with SSs and non-SSs. The base station may transmit an indication of the SS burst set pattern to a wireless device. The wireless device may receive the indication of the SS burst set pattern and determine one or more time locations of SSs (e.g., primary synchronization signal (PSS), secondary synchronization signal (SSS), physical broadcast channel (PBCH) of a SS block). The wireless device may then monitor the identified positions for SSs.

Abstract: An apparatus includes an interface and a processor. The interface communicates with a network including network elements interconnected in a Cartesian topology. The processor defines first and second groups of turns, each turn includes a hop from a previous network element to a current network element and a hop from the current network element to a next network element. Based on the turns, the processor specifies rules that when applied to packets traversing respective network elements, guarantee that no deadlock conditions occur in the network. The rules for a given network element include (i) forwarding rules to reach a given target without traversing the turns of the second group, and (ii) Virtual Lane (VL) modification rules for reassigning packets, which traverse turns of the first group and which are assigned to a first VL, to a different second VL. The processor configures the given network element with the rules.

Abstract: A method of routing a data packet through a network comprises updating at least one router local forwarding table to include path IDs of network segments defining paths between network nodes and network function bit encoding/decoding information. In response to a data packet arriving at an ingress network node, an encapsulation header including a path ID identifying at least one network segment of an explicit routing path and a bit encoding specifying network functions to be performed on the data packet are encapsulated in unused portions of the source address and/or the destination address in the encapsulation header. A network node in the explicit routing path performs a network function encoded in the source address and/or the destination address of the encapsulation header of the data packet and forwards the data packet based on network function bit encoding/decoding and path ID information in the network node's local updated local forwarding table.
