Abstract: A method embodiment includes receiving, by a first network device, a first transmission comprising an explicit first source identification (ID). The first source ID is added to a list of active source IDs. The first network device receives a second transmission. The second transmission does not include an explicit second source ID. The first network device determines the second source ID by using the list of active source IDs.

Abstract: A method embodiment includes implementing, by a base station (BS), a grant-free uplink transmission scheme. The grant-free uplink transmission scheme defines a first contention transmission unit (CTU) access region in a time-frequency domain, defines a plurality of CTUs, defines a default CTU mapping scheme by mapping at least some of the plurality of CTUs to the first CTU access region, and defines a default user equipment (UE) mapping scheme by defining rules for mapping a plurality of UEs to the plurality of CTUs.

Abstract: Hierarchical Software Defined Network (SDN) architectures can be used to reduce complexity of traffic engineering in large or diverse network environments. In hierarchical SDN architectures, a network is sub-divided into multiple regions, and each region is assigned to a different SDN controller. Network status information is collected and consolidated at a regional level, and fed upstream through the SDN control plane until it reaches a root SDN controller. The root-SDN controller computes cost-based parameters, which are distributed to regional SDN controllers for local provisioning. The cost-based parameters can include Lagrangian variables estimations or other parameters that constrain regional traffic engineering optimization in a manner that advances global traffic engineering objectives.

Abstract: In a wireless (e.g., machine-to-machine) network, items of user equipment compete for wireless communication resource slots (“resources”). In a contention period, an item of user equipment (a UE) sends a first signal to a base station using a first resource. The first resource is mapped to a second resource in a data transmission period. If the base station successfully receives the first signal, it sends a second signal to the UE to confirm that the UE has been awarded the second resource and can transmit data in the data transmission period.

Abstract: Methods and devices for reducing traffic over a wireless link through the compression or suppression of high layer packets carrying predictable background data prior to transportation over a wireless link. The methods include intercepting application layer protocol packets carrying the predictable background data. In embodiments where the background data is periodic in nature, the high layer packets may be compressed into low-layer signaling indicators for communication over a low-layer control channel (e.g., an on off keying (OOK) channel). Alternatively, the high layer packets may be suppressed entirely (not transported over the wireless link) when a receiver side daemon is configured to autonomously replicate the periodic background nature according to a projected interval. In other embodiments, compression techniques may be used to reduce overhead attributable to non-periodic background data that is predictable in context.

Abstract: A software designed protocol (SDP) network node includes a receiver, and a processor operatively coupled to the receiver. The receiver receives instructions, and receives packets. The processor updates a configuration of the SDP network node in accordance with the received instructions, and processes the received packets.
