Abstract
According to an aspect, there is provided a method for transmitting a low-power radio signal, comprising: transmitting, by a radio device, a data radio signal by using binary frequency-shift-keying modulation introducing a phase change between consecutive bit intervals in the data radio signal; and transmitting, by the radio device, a wake-up radio signal using the binary frequency-shift-keying modulation where repetition coding is applied before the frequency-shift-keying to eliminate the phase change between consecutive bit intervals in the wake-up radio signal.

A method for transmitting a low-power radio signal, comprising:
- transmitting, by a radio device, a data radio signal by using binary frequency-shift-keying modulation introducing a phase change between consecutive bit intervals in the data radio signal;
- and
- transmitting, by the radio device, a wake-up radio signal using the binary frequency-shift-keying modulation where repetition coding is applied before the frequency-shift-keying to eliminate the phase change between consecutive bit intervals in the wake-up radio signal.
A method for receiving a low-power radio signal, comprising:
- receiving, by a wake-up radio interface of a radio device, a wake-up radio signal using binary frequency-shift-keying modulation having repetition coding and a constant phase between consecutive bit intervals, each bit interval comprising a number of modulation symbol intervals dependent on a length of the repetition coding;
- upon receiving the wake-up radio signal, enabling a main radio interface of the radio device;
- and
- receiving, by the main radio interface, a data radio signal using binary frequency-shift-keying modulation introducing a phase change between consecutive bit intervals in the data radio signal.
An apparatus for low-power radio transmissions, comprising means for:
- causing transmission of a data radio signal by using binary frequency-shift-keying modulation introducing a phase change between consecutive bit intervals in the data radio signal;
- and
- transmitting a wake-up radio signal using the binary frequency-shift-keying modulation where repetition coding is applied before the frequency-shift-keying to eliminate the phase change between consecutive bit intervals in the wake-up radio signal.
