Advanced LAA planning for multi-point sub-transmission in shared cells

摘要

Systems and methods are disclosed relating to implementing a shared cell configuration in a heterogeneous deployment of, e.g., a License Assisted Access (LAA) network. In some embodiments, a method of operation of a processing system to schedule downlink transmissions to wireless devices in a shared cell in an unlicensed frequency spectrum, the shared cell being served by multiple Reception/Transmission (R/T) points, comprises receiving independent Clear Channel Assessment (CCA) decisions from the R/T points serving the shared cell, each CCA decision from each R/T point being indicative of whether a CCA succeeded or failed at the R/T point. The method further comprises performing scheduling for one or more upcoming Transmit Time Intervals (TTIs) based on the CCA decisions received from the R/T points serving the shared cell.
