An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set.

Abstract: A wireless communication device receives OFDM radio signals having different numerologies (i.e. different sub-carrier spacing) and determines whether the transmission, by one or more transmitting nodes, of the OFDM signals are coordinated. The meaning of “coordinated” is to be understood as the OFDM signals are time-synchronized and the determination of whether the OFDM signals are coordinated may involve such actions as reading broadcast or receiving configuration message transmitted in the system, determining a relation (for instance cell/access point beam identity) between transmitted synchronization or reference signals. If the OFDM signals are determined to be coordinated, time and/or frequency offset for the second OFDM signal having the second subcarrier spacing is derived based on the time and/or frequency offset associated with the first OFDM signal having the first subcarrier spacing.
