1. A method for determining a resource block group size, comprising:
receiving, by a terminal 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;
receiving, by the terminal device, Downlink Control Information (DCI);
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 the DCI to schedule the resource;
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, receiving, by the terminal device, second configuration information sent from a network device, and determining whether a second Radio Network Temporary Identifier (RNTI) can be used according to the second configuration information, 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, according to a Radio Network Temporary Identifier (RNTI) used for scrambling the DCI and a BandWidth Part (BWP) size, determining, by a terminal device, a resource block group size used for the DCI to schedule a resource; and
when the second RNTI cannot be used, determining by the terminal device, the resource block group size used for the DCI according to a preset rule.
