1. A method, applied in a terminal device, the method comprising:
receiving a master information block (MIB) from a network device, wherein the MIB indicates a bandwidth of a control resource set 0 (CORESET 0), wherein the CORESET 0 is used to schedule a system information block (SIB) 1;
when the terminal device is in a radio resource control (RRC) idle state or an RRC inactive state, determining, based on the MIB, that a bandwidth of an initial bandwidth part (BWP) is a second bandwidth, wherein the second bandwidth is the bandwidth of the CORESET 0; receiving a connection configuration message Msg4;
entering an RRC connected state in response to receiving the connection configuration message Msg4; and
when the terminal device enters the RRC connected state from the RRC idle state or the RRC inactive state, adjusting, based on the SIB 1, the bandwidth of the initial BWP from the second bandwidth to a first bandwidth after determining that a connection setup complete message or an RRC resume complete message needs to be sent to the network device, wherein the first bandwidth is indicated by the SIB 1, and wherein the first bandwidth is greater than the second bandwidth.
