1. A method for receiving downlink control information (DCI), the method being performed by a terminal and comprising:
receiving bandwidth part (BWP) configuration information transmitted by an access network device, the BWP configuration information configuring a target BWP located in an unlicensed spectrum and comprises m sub-bands, m being a positive integer greater than 1;
determining the m sub-bands of the target BWP according to the BWP configuration information;
monitoring a target sequence at a first time domain position on all or part of the m sub-bands respectively, wherein the first time domain position is one of a time-frequency position pre-determined by a communication protocol, or a time domain position pre-configured by the access network device during a procedure of configuring the target BWP; and the target sequence is configured to identify sub-bands on which Listen Before Talk (LBT) is successful in the m sub-bands, or to identify sub-bands on which the DCI is transmitted in the m sub-bands; and
monitoring DCI on all or part of the m sub-bands after the target sequence is detected.
