摘要： A computer-implemented method executed on a processor for employing an epoch-based approach to estimating interference in an unlicensed spectrum is presented. The method includes enabling communication between a long-term evolution (LTE) evolved node B (eNodeB) and a plurality of clients, detecting and measuring the interference in all existing non-overlapping channels, via the LTE eNodeB, caused by one or more hidden clients of the plurality of clients, collecting interference statistics from all of the plurality of clients across all different channels, and leveraging interference-awareness resulting in channel access performance improvement at a macro-time scale and a micro-time scale.

摘要： A base station for secondary-cell (S-cell) operation in an unlicensed band is subject to listen-before-talk (LBT) rules. The apparatus generates S-cell discovery reference signal (DRS) that includes a primary synchronization signal (PSS) based on a cell ID associated with the base station, a secondary synchronization signal (SSS), a cell-specific reference signal (CRS), and optionally CSI-RS. Solutions are described for generating portions of the DRS to accommodate the placement of the DRS in arbitrary subframes.
