Claim 2:
3. A communication control method comprising:
performing, by a processor, delay control on radio data according to a first delay time that is less than a basic frame unit processing time, in units of basic frames of a CPRI (Common Public Radio Interface) frame, based on a desired data transmission timing in a radio device;
multiplexing, by the processor, the radio data that has undergone the delay control,
wherein the delay control is performable on the radio data according to a plurality of delay times less than the basic frame unit processing time;
selecting, by the processor, the first delay time from the plurality of delay times, based on the desired data transmission timing;
storing, by the processor, a plurality of tables that each include a plurality of tap coefficients corresponding to the plurality of delay times; and
selecting, by the processor and from the plurality of tables, the table retaining the plurality of first tap coefficients, based on the desired data transmission timing; and
implementing, by the processor, a digital filter in which a plurality of first tap coefficients corresponding to the first delay time are set for a multiplier.
