Multi numerology transmission method for a radio communication system

Abstract:

A first network node (200), a wireless device (202) and methods therein, for radio communication. The first network node determines first (2:1) and second (2:3) numerologies for communication of a reference signal and data, respectively, the first and second numerologies defining different combinations of subcarrier spacing and time between two successive OFDM symbols. The first network node then configures (2:4) the wireless device with the first and second numerologies and transmits (2:5) an assignment of data in the second numerology to the wireless device, the assignment comprising a trigger for the reference signal. Thereby, the first network node and the wireless device can communicate (2:6) the reference signal using the first numerology, and communicate (2:7) the data using the second numerology.
