    Abstract: This disclosure relates to the mobile communications field, and in particular, to data transmission technologies in the mobile communications field. In a data transmission method, a base station allocates, to a terminal, some of time domain symbols that are used for data transmission and that are in a scheduling period of the terminal, and the terminal performs data transmission based on the allocated time domain symbols. According to the method, time domain symbols in the scheduling period that originally belong to the terminal are punctured, a resource waste caused when the terminal occupies all time domain symbols that are used for data transmission and that are in the scheduling period during scheduling each time can be avoided, so that radio resources can be flexibly allocated based on requirements on delays and bandwidth, thereby improving resource utilization.

    Abstract: Embodiments of the present invention disclose a base station, user equipment (UE), and a carrier scheduling indication method to resolve a problem that signaling overheads are relatively large. An embodiment method includes generating, by a processing unit, a carrier assignment indication (CAI) field of a current scheduled carrier according to scheduling statuses of all configured carriers, where the CAI field is used to indicate a total quantity of scheduled carriers in all the configured carriers and an accumulative index value M of the current scheduled carrier, and M represents that the current scheduled carrier is the Mth scheduled carrier from the 1st configured carrier to the current scheduled carrier; and sending, by a sending unit, downlink control information digital control information (DCI), by carrying the CAI field generated by the processing unit to the DCI, to UE by using the current scheduled carrier disclosed in the present embodiments shall fall within the protection scope of the present embodiments. Therefore, the protection scope of the present embodiments shall be subject to the protection scope of the claims.

    Abstract: 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.
