1. A method comprising:
determining, by a wireless node in a cell, a silent resource pattern for each of a plurality of signal waveform types including at least a single carrier waveform type and a multicarrier waveform type, wherein each silent resource pattern identifies one or more resource elements that are indicated as unused by at least one node of the cell for the signal waveform type;
determining, by the wireless node, whether a signal waveform type, of the plurality of signal waveform types, for channel sensing is known by the wireless node;
performing, by the wireless node if a signal waveform type for channel sensing is known by the wireless node, channel sensing based on a silent resource pattern for a known signal waveform type for channel sensing of the plurality of signal waveform types;
otherwise, performing, by the wireless node if the signal waveform type for channel sensing is not known by the wireless node, channel sensing based on a silent resource pattern for each of a plurality of the signal waveform types.
