Abstract: Systems and methods are provided to improve data transmission efficiency over a network. The improvements are achieved by reducing the redundancy in the data representation. The data is divided into a plurality of data portions. The data portions are used to encode a plurality of compressed data portions, wherein the compressed data portions correspond to a subset of the data portions and comprise less redundant data than the subset of the data portions. The compressed data portions are also encoded in accordance with data in the remaining data portions. The compressed data portions are transmitted instead of the subset of the data portions with the remaining data portions according to a sequence of data portions. Each of the compressed data portions is transmitted upon receiving an acknowledgment (ACK) message that indicates successful transmission of a previous data portion or compressed data portion in the sequence of data portions.

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.
