Data transmission control method, apparatus, and access network device

A communications apparatus for a first communications apparatus, comprising a processor;

• and a memory coupled to the processor and storing executable non-transitory instructions that, when executed by the processor, cause the first communications apparatus to:
• receive radio frequency signals;
• process the radio frequency signals in at least two functional split manners, to generate at least two parts of transmission signals;
• send the at least two parts of transmission signals to a second communications apparatus;
• and
• divide the radio frequency signals into at least two parts of signals, wherein
• each of the at least two functional split manners is used to determine functional split on the first communications apparatus and the second communications apparatus when the radio frequency signals are processed;
• the radio frequency signals are carried on at least two resource blocks (RBs), the at least two parts of signals comprise a first part of signals and a second part of signals, and the processor that causes the first communications apparatus to divide the radio frequency signals into at least two parts of signals comprises:
• classifying a radio frequency signal carried on at least one RB with a quantity of user data streams greater than or equal to a stream quantity threshold as the first part of signals;
• and
• classifying a radio frequency signal carried on at least one RB with a quantity of user data streams less than the stream quantity threshold as the second part of signals.
