Claim 7:
8. A method for determining a resource block group size, comprising:
sending, by a network device, first configuration information, wherein the first configuration information comprises selection information regarding a resource block group size configuration, and the resource block group size configuration comprises at least a first resource block group size configuration and a second resource block group size configuration;
when a value of the first configuration information is a first value, the first configuration information indicates that both the first resource block group size configuration and the second resource block group size configuration are used for Downlink Control Information (DCI) to schedule a resource;
sending, by the network device, the DCI which is scrambled by a Radio Network Temporary Identifier (RNTI);
when both the first resource block group size configuration and the second resource block group size configuration are used for the DCI to schedule the resource, sending, by the network device, second configuration information sent to a terminal device;
wherein the RNTI and a BandWidth Part (BWP) size are used for a terminal device to determine a resource block group size used for the DCI to schedule the resource, and the second configuration information is used for the terminal device to determine whether a second RNTI can be used, the second RNTI is different from a first RNTI, and the first RNTI is a Cell-Radio Network Temporary Identifier (C-RNTI);
when the second RNTI can be used, the terminal device determines a resource block group size used for the DCI to schedule a resource according to the RNTI used for scrambling the DCI and the BWP size; and
when second RNTI cannot be used, determining by the terminal device, the resource block group size used for the DCI according to a preset rule.
