1. A method performed by a network node, the method comprising:
selecting either a Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) format or Orthogonal Frequency Division Multiplexing (OFDM) modulation format for receiving transmissions for a random access procedure; and,
configuring with a broadcast channel at least one of a plurality of wireless devices to use the selected modulation format for uplink transmissions by indicating in system information the selected DFTS-OFDM or OFDM modulation format to be used for a message 3 transmission, wherein the at least one of the plurality of wireless devices is required to obey the configuration.
