Abstract: Methods and systems for providing joint power control (PC) and scheduling in a wireless network are provided. In one example, a method includes generating a near-optimal power pattern for PC and scheduling in accordance with long term channel statistics. The near-optimal PC solution may be generated by first generating a set of possible power patterns in accordance with likely scheduling scenarios, then statistically narrowing the set of possible power patterns to identify the most commonly used power patterns, and finally selecting one of the most commonly used power patterns as the near-optimal power pattern. In another example, a table of optimal PC solutions are provided for performing distributed PC and scheduling in an adaptive and/or dynamic manner.

Abstract: Methods and systems for facilitating uplink power control (PC) and scheduling in a wireless network are provided. In one example, common interference patterns are obtained from long term channel statistics, and used to perform local PC and scheduling by distributed base stations (eNBs). In some implementations, the common interference patterns are obtained through statistical narrowing techniques that identify common ones out of a plurality of potential interference patterns. The common interference patterns may specify maximum interference thresholds and/or individual eNB-to-eNB interference thresholds which may govern the local PC and scheduling decisions of the distributed eNBs.

Abstract: Hierarchical compression includes the contemporaneous implementation of link-layer and higher-layer compression on data flowing over a link. Hierarchical compression can be achieved by configuring network nodes positioned at the link-layer to recognize higher-layer compression symbols embedded in incoming data streams, and to adapt link-layer compression to compensate for those higher-layer compression symbols. One technique for adapting link-layer compression is to perform data chunking in-between higher-layer compression symbols. This may reduce the likelihood that higher-layer compression symbols will interfere with the network nodes ability to identify redundant data chunks at the link-layer. Another technique for adapting link-layer compression is to define the HASH algorithm in such a way that the hash of a data string renders the same hash value as the hash of the higher layer compression symbol corresponding to the data string.
Abstract translation: 层次压缩包括链路层和更高层压缩在链路上流动的数据的同时实现。 可以通过配置位于链路层的网络节点来识别嵌入到输入数据流中的较高层压缩符号，并适应链路层压缩以补偿那些较高层压缩符号来实现分级压缩。 用于适应链路层压缩的一种技术是在较高层压缩符号之间执行数据块分组。 这可能会降低高层压缩符号会干扰网络节点识别链路层冗余数据块的可能性。 用于适应链路层压缩的另一技术是以这样的方式定义HASH算法，即数据串的散列表示与对应于数据串的较高层压缩符号的散列相同的散列值。
