Claim 3:
4. A method for activating a bandwidth part (BWP), comprising:
sending, by a network device, second downlink control information (DCI) to a terminal device, wherein a first BWP of the terminal device is in an active state, the second DCI is scrambled by a second radio network temporary identifier (RNTI), the second DCI is used for indicating a second BWP, the first BWP is not activated by the second DCI, and the second DCI is used by the terminal device to maintain the active state of the first BWP and activate the second BWR;
wherein the second DCI comprises an indicator of the second BWP;
before sending, by the network device, the second DCI to the terminal device, further comprising:
sending, by the network device, second configuration information to the terminal device, wherein the second configuration information comprises at least one configuration sub-information, and the configuration sub-information is used for indicating a corresponding relationship between a configuration parameter of at least one BWP included in a group of BWPs and an intra-group number of the at least one BWP, and the group of BWPs corresponds to one RNTI, a configuration parameter of a fifth BWP among the at least one BWP comprises a subcarrier spacing of the fifth BWP, a cyclic prefix type of the fifth BWP, a number of resource blocks and frequency domain positions of the resource blocks included in the fifth BWP, wherein the fifth BWP is any one BWP of the at least one BWP, the indicator of the second BWP comprised in the second DCI is an intra-group number of the second BWP, and the intra-group number of the second BWP is used by the terminal device to determine the second BWP in a BWP group corresponding to the second RNTI.
