    摘要: Systems and methods for reducing overhead in a communication system are disclosed. Different frame types are aggregated into an enhanced aggregated frame in response to a determination that the different frames are suitable for transmission within a single reservation period. In an embodiment, at least two frames of different types are identified, the suitability of an aggregated frame comprising at least a portion of each of the at least two frames for transmission during a first time duration is determined, and if suitable the aggregated frame is formatted for transmission by a transceiver. If unsuitable for transmission in the first time duration, a second time duration longer than the first time duration in which the aggregated frame is suitable for transmission is defined, and the aggregated frame is formatted for transmission by the transceiver.

    摘要: Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing.

    摘要: Methods, systems, and devices for utilizing flexible bandwidth carriers for small cells are provided. Bandwidth scaling factor(s) for a small cell may be determined. A flexible bandwidth carrier may be generated for the small cell utilizing the bandwidth scaling factor. Some embodiments provide assistance with active hand-in due to more available PN offsets in the flexible bandwidth domain. Some embodiments enhance small cell discovery with high bandwidth scaling factor beacon-like small cells with little more power than that corresponding to the same power spectral density for normal bandwidth small cell. Some embodiments reduce the interference caused by small cell to macrocell users using an adaptive bandwidth scaling factor for small cells based on number of users supported and their traffic demand, to control the extent of overlap the macrocell has with small cell and the interference to macrocell mobiles. Some embodiments utilize self-configuration for small cells utilizing flexible bandwidth channels.

    摘要: A demand aware fair resource allocation technique is operable to allocate communication resources in multi-hop networks under the joint consideration of communication requirements and fairness. Embodiments operate to provide allocation of time slot resources in TDMA based multi-hop wireless networks under the joint consideration of QoS and fairness. Embodiments operate with respect to information regarding maximal common slot set flow contention. An iterative process is applied with respect to the information regarding maximal common slot set flow contention to allocate communication resources providing a balance between meeting communication requirements and fairness. According to embodiments, an inter-graph process iteratively selects a maximal common slot set for which resource allocation with respect to various flows is to be performed and an intra-graph process assigns communication resources in the maximal common slot set providing a balancing between meeting communication requirements (e.g., QoS) and providing fairness.
