Abstract
Embodiments of this application provide a signal sending method, including: determining a first subcarrier, wherein an offset is between the first subcarrier and a center subcarrier of target resource blocks in a target bandwidth, and the offset is related to a subcarrier spacing; and determining a signal, wherein a location of the first subcarrier is the same as a carrier frequency location of the signal.
Claims22
A communication method, comprising:
- determining, by a communications apparatus, a first subcarrier, an offset being between the first subcarrier and a center subcarrier of target resource blocks in a target bandwidth, the offset being related to a subcarrier spacing, the subcarrier spacing corresponding to the first subcarrier being a maximum subcarrier spacing of a carrier, the carrier comprising the target bandwidth, and the first subcarrier satisfying:
- k=floor(N*12/2/2{circumflex over ( )}(umax−umin))*2{circumflex over ( )}(umax−umin)+2{circumflex over ( )}(umax−umin)
- where umin is a minimum subcarrier spacing supported by the communications apparatus in the target bandwidth, umax is a maximum subcarrier spacing supported by the communications apparatus in the target bandwidth, N indicates a quantity of resource blocks corresponding to the minimum subcarrier spacing umin in the target bandwidth, and floor(x) indicates rounding x down;
- determining, by the communications apparatus, a signal, a frequency location of the first subcarrier being the same as a carrier frequency location of the signal;
- and
- transmitting, by the communications apparatus, the signal.
