Claim 16:
17. A method comprising:
transmitting, by an apparatus, orthogonal frequency division multiplexing (OFDM) signal parameters including a first subcarrier spacing of a first numerology μ, a value of a first offset Ngrid,xstart,μ in units of resource blocks (RBs), a quantity Ngrid,xstart,μ of usable RBs of the first numerology μ, a value of a second offset Ngrid,xstart,μ0 in units of RBs, and a quantity Ngrid,xstart,μ0 of usable RBs of a reference numerology μ0, wherein:
x identifies a transmission direction being either downlink (DL) or uplink (UL),
the first offset is between a reference point and a start of the usable RBs of the first numerology μ, and
the second offset is between the reference point and a start of the usable RBs of the reference numerology μ0; and
transmitting or receiving, by the apparatus, an OFDM signal associated with a third offset, wherein a value k0,xμ of the third offset satisfies:

k0,xμ=(Ngrid,xstart,μ+Ngrid,xsize,μ/2)NscRB−(Ngrid,xstart,μ0+Ngrid,xsize,μ0/2)NscRB2μ0−μ, and wherein NscRB indicates a quantity of subcarriers in a RB.
