Claim 0:
1. A method for activating a bandwidth part (BWP), comprising:
receiving, by a terminal device, second downlink control information (DCI) sent by a network 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, and the first BWP is not activated by the second DCI; and
maintaining, by the terminal device, the active state of the first BWP and activating the second BWR;
wherein the second DCI comprises an indicator of the second BWP;
wherein before receiving, by the terminal device, the second downlink control information (DCI) sent by the network device, further comprising:
receiving, by the terminal device, second configuration information sent by the network device, wherein the second configuration information comprises at least one configuration sub-information, the configuration sub-information is used for indicating a corresponding relationship between a configuration parameter of at least one BWP comprised in a group of BWPs and an intra-group number of the at least one BWP, 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, and a number and a frequency domain position of resource blocks comprised in the fifth BWP, wherein the fifth BWP is any one BWP among the at least one BWP;
after receiving, by the terminal device, the second downlink control information (DCI) sent by the network device, further comprising:
determining, by the terminal device, the second RNTI according to the second DCI, wherein the indicator of the second BWP comprised in the second DCI is an intra-group number of the second BWP; and
determining, by the terminal device, the second BWP, within a BWP group corresponding to the second RNTI, according to the intra-group number of the second BWP.
