摘要： A method of performing channel estimation for a radio channel between a transmitter and a receiver of a radio access network, RAN comprises the step of performing an initial channel estimation (204) of the radio channel for each of a plurality of frequency ranges (502), based on a radio signal received on the radio channel from the transmitter, the radio signal comprising a signal sequence (510) out of the set of signal sequences (510) in each of the frequency ranges (502), to obtain an initial channel estimate (504) for each frequency range (502), and applying a filter (206) to the initial channel estimates (504) for the frequency ranges (502), a length (508) of the filter (206) in the frequency domain being greater than lengths of the frequency ranges (502), to obtain a filtered channel estimate (506) for all subcarriers (406) in the respective one of the frequency ranges (502).

摘要： The scheduling flexibility of CSI reference signals enables time and frequency synchronization using multiple non-zero CSI-RSs transmitted in the same subframe, or using CSI-RSs transmitted in the same subframe with other synchronization signals. Also, multiple synchronization signals may be scheduled in the same subframe to enable fine time and frequency synchronization without cell-specific reference signals.

摘要： Systems and methods are disclosed herein that relate to multiple candidate starting points for a transmit burst in unlicensed spectrum. In some embodiments, a method of operation of a radio access node for performing a transmit burst in an unlicensed spectrum comprises transmitting a transmit burst in an unlicensed spectrum, wherein the transmit burst spans multiple subframes/slots and the transmitting of the transmit burst starts at one of a plurality of candidate starting points defined in at least a first subframe/slot of the transmit burst that occurs after successful completion of a Listen-Before-Talk (LBT) procedure for the transmit burst. In this manner, a radio access node (e.g., an enhanced or evolved Node B (eNB) in Long Term Evolution (LTE)) has flexibility to transmit a downlink transmit burst starting at different starting positions based on LBT outcome.
