  • Publication number: 20180242309
    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.

  • Patent number: 10015057
    Abstract: Systems and methods for a representative bandwidth calculation in a network include receiving a request for representative bandwidth information; obtaining network measurements; combining, filtering, and retiming network measurements based on the request to determine the representative bandwidth information. The systems and methods convert the combined, filtered, and retimed network measurements into the representative bandwidth information which has an additive property in an algebraic domain. The additive property enables the representative bandwidth information to be used for admission control, overbooking determinations, network planning, and/or dynamic pricing in the network.

  • Patent number: 10009287
    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.

  • Patent number: 9980284
    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.

  • Patent number: 9832681
    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.
