說明書
As an example, for a format of a preamble signal symbol, the preamble signal symbol includes a second CP and M information segments. The M information segments share the second CP, and M is a positive integer that is greater than or equal to 2. That is, the M information segments are repeatedly sent (which means that signals sent on the M information segments are same).
As an example, a length of the second CP is greater than a length of the first CP.
As an example, the length of the second CP is a length of M first CPs.
A method for determining the first time-point according to a format of preamble signal symbol will be described in detail below.
For example, the first time-point may be a starting point of an information segment, a starting point of a CP, or a starting point of the preamble signal symbol.
It should be understood that, as described above, the first time-point may be a time-point determined according to the format of preamble signal symbol, but it should be understood that it is not limited to this in the embodiments of the present disclosure.
There are many ways to determine a subcarrier spacing of a preamble signal. A way for determining the subcarrier spacing of the preamble signal is described below. In this embodiment of the present disclosure, the subcarrier spacing corresponding to the preamble signal symbol may be referred to as a first subcarrier spacing.
