RADIO NETWORK NODE, WIRELESS DEVICE AND METHODS THEREOF USING GMSK MODULATION APPLYING NEGATIVE MODULATION INDEX

摘要

A radio network node comprised, and a wireless device configured to be operative, in a wireless communication system. The radio network node obtains downlink data and converts it to a baseband signal. The conversion comprises Gaussian Minimum Shift Keying (GMSK) modulation of the downlink data. The modulation applies a negative modulation index selected based on a type of wireless device that is a target for the downlink data. A radio signal is provided based on the baseband signal and sent to, and received by, the wireless device that provides user data based on the radio signal.
