Abstract

The application provides a bandwidth determination method and device. The method comprises the following steps: a communication device determines a sending bandwidth according to a bandwidth part (BWP), a channel bandwidth (CBW), a target bandwidth (TBW) and a bias protection bandwidth. According to the BWP, the CBW, the TBW and the bias protection bandwidth, a suitable sending bandwidth can be adaptively selected, which is beneficial to meeting the requirement of out-of-band leakage.
