Abstract
Provided is a transmission bandwidth configuration method. The method includes: configuring a first channel bandwidth (CB) of a carrier; and in response to determining that the first CB is greater than a first preset bandwidth, configuring subcarriers in a first TBC according to a preset percentage X of the first TBC in the first CB and the first CB, so as to complete a subcarrier configuration in a transmission bandwidth configuration. The preset percentage X is within a range of [a preset lower limit value, a preset upper limit value], the preset lower limit value is greater than 90% and the preset upper limit value is less than 100%. Also provided is a transmitting node.
