Subcarrier spacing is that terminal is determined according to the subcarrier spacing of lead code, alternatively, default subcarrier spacing is predefined.Also
It is to say, the subcarrier spacing that transmitting uplink data uses, which can be, to be determined by the corresponding subcarrier spacing of lead code, either
It is determined by way of pre-configuration.
It is for terminal is determined according to the subcarrier spacing of lead code by default subcarrier spacing, terminal is according to lead code
Subcarrier spacing determines the default subcarrier spacing, may include:
When the subcarrier spacing of lead code is greater than or equal to the first default subcarrier spacing, subcarrier spacing is preset with before
The subcarrier spacing of leading code is identical.Wherein, by taking the first default subcarrier spacing is 15KHz as an example, when the first format transmission of use
When, the subcarrier spacing of lead code is greater than or equal to 15KHz, wherein the first format be format set FormatA1,
FormatA2, FormatA3, FormatB1, FormatB2, FormatB3, FormatB4, FormatC0, FormatC2 } in
Any one.At this moment, the subcarrier spacing that transmitting uplink data uses is identical as lead code subcarrier spacing.
When the subcarrier spacing of lead code is less than the first default subcarrier spacing, subcarrier spacing and lead code are preset
Subcarrier spacing is different.Wherein, leading when using the second format transmission by taking the first default subcarrier spacing is 15KHz as an example
Code subcarrier spacing be less than 15KHz, wherein the second format be format set Format0, Format1, Format2,
Any one of Format3 }.At this moment, the subcarrier spacing that transmitting uplink data uses is different from lead code subcarrier spacing.
