Claim of US Patent No. 10,772,106

1. A method of operation by a wireless device operating in a wireless communications network, the method comprising:determining a preferred subcarrier spacing to use for communicating data between the wireless device and a radio network node of the wireless communications network via an Orthogonal Frequency Division Multiplexing (OFDM) carrier, the determining made by the wireless device in dependence on communication performance or power consumption criteria, wherein determining the preferred subcarrier spacing comprises determining two or more preferred combinations of subcarrier spacing and Modulation and Coding Scheme (MCS) to use for communicating the data between the wireless device and the radio network node; and
indicating the preferred subcarrier spacing to the radio network node, wherein indicating the preferred subcarrier spacing comprises indicating the two or more preferred combinations of subcarrier spacing and MCS and further indicating an order of preference for the two or more preferred combinations.
