  • Publication number: 20140328183
    Abstract: Diverse traffic types can be efficiently communicated in a simultaneous manner by dynamically selecting between contention-based and scheduling-based media access control (MAC) communication schemes. Such a mechanism may be particularly beneficial in networks having a contention-based access resources and scheduling based access resources. Contention-based resources and scheduling based resources may occur over a common period, and may be orthogonal in the frequency domain and/or in the code domain. The dynamic selection may be based on a traffic characteristic or a network characteristic, and may be performed on a packet-by-packet basis. The selection criteria may be updated dynamically to adapt to changing network conditions, and may be communicated to the various transmitters via control channels or higher layer signaling.

  • Patent number: 8817624
    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.

  • Publication number: 20140229210
    Abstract: Embodiments are provided for network resource allocation considering user experience, satisfaction, and operator interest. An embodiment method by a network component for allocating network resources includes evaluating, for a user, a QoE for each flow of a plurality of flows in network traffic in according with a QoE model, and further evaluating, for an operator, a revenue associated with the flows in accordance with a revenue model. A plurality of priorities that correspond to the flows are calculated in accordance with the QoE for the user and the revenue for the operator. The method further includes identifying a flow of the flows with a highest value of the priorities, and allocating a network resource for the flow. In an embodiment, the QoE model is a satisfaction model that provides a measure of user satisfaction for each flow in accordance with a subscription or behavior class of the user.

  • Publication number: 20140192767
    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.
