    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: System and method embodiments are provided for pausing data transmission in a full-duplex wireless network. Embodiments eliminate the deadlocks in the full duplex MAC layer and improve the system efficiency. In an embodiment, a method in a wirelessly enabled and full duplex enabled network component for pausing an ongoing data transmission includes beginning a transmission, with the network component, of first data to a first station; determining, with the network component, that transmission of a second data to a second station is required before completion of the transmission of the first data to the first station; transmitting, with the network component, a pause indicator to the first station notifying the first station that transmission of the first data will be paused; transmitting, with the network component, the second data to the second station; and resuming transmitting, with the network component, the first data to the first station.

    Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.

    Abstract: Embodiments are provided for a framework for networks with software defined protocols (SDP) network nodes. The embodiments include a SDM controller component for managing and controlling a data plane protocol for SDP network nodes. The SDP controller also interacts with a software defined networking (SDN) controller for determining one or more paths in a network including the SDP network nodes. The SDP controller is configured to determining a break-down of data plane process functionality into a plurality of basic process function blocks for a service, traffic flow, or virtual network in accordance with network component capabilities or quality of service/experience requirement. A workflow and status information are also determined for one or more network components along a path allocated, by the SDN controller. The workflow and status information are indicated to the one or more components, which are configured to implement the workflow using the basic process function blocks.
