A resource allocation method to resolve a problem that a transport block of a typical enhanced voice service (EVS) scenario in an air interface is much smaller than a transport block of a conventional adaptive multi rate (AMR), and use of a resource allocation method in the existing long term evolution (LTE) causes a waste of user spectrum resources such that spectrum utilization in an EVS scenario can be improved. The method includes determining resource allocation information and resource allocation block indication information, where the resource allocation information includes information indicating at least one fractional resource block (FRB) allocated to user equipment, and the resource allocation block indication information indicates that a resource allocation block is the FRB, where a resource occupied by the FRB is less than one RB, and notifying the user equipment of the resource allocation information and the resource allocation block indication information.
