Claim 7:
8. A terminal device, comprising:
a transceiver, configured to receive second downlink control information (DCI) sent by a network device, wherein a first BWP (bandwidth part) 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
a processor, configured 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;
wherein the transceiver is further configured to:
before receiving the second DCI sent by the network device, receive 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 included in a group of BWPs and an intra-group number of the at least one BWP, the group of BWP 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 comprised in the fifth BWP, wherein the fifth BWP is any one BWP among the at least one BWP;
and the processor is further configured to:
after receiving, by the transceiver, the second DCI sent by the network device, determine the second RNTI according to the second DCI, wherein the indicator of the second BWP included in the second DCI is an intra-group number of the second BWP; and
within a BWP group corresponding to the second RNTI, determine the second BWP according to the intra-group number of the second BWP.
