Patent ID: 10064174

Abstract:
Systems and methods relating to Discovery Signal Measurement Timing Configuration (DMTC) are disclosed. In some embodiments, a method of operation of a radio access node in a cellular communications network comprises sending, to a wireless device, a DMTC for one of a group consisting of: (a) a Secondary Cell (SCell) configured for the wireless device such that the DMTC is a specific DMTC for the SCell and (b) a frequency on which one or more asynchronous cells are operating, an asynchronous cell being a cell that is unsynchronized with a Primary Cell (PCell) of the wireless device. A DMTC configuration that is specific to a SCell provides improved measurement performance on the SCell because, e.g., the DMTC configuration can be specifically tailored to that SCell. A DMTC configuration for a frequency on which one or more asynchronous cells are operating provides improved measurement performance on that carrier.
