1. A system, comprising:
at least one processor; and
at least one memory coupled to the processor, comprising instructions that cause the at least one processor to perform operations comprising:
as part of a user equipment attaching to the system, sending, to the user equipment, a message that comprises a first value that indicates that the system is able to support modification of a first number of additional demodulation reference signal positions after the attaching to the system, wherein the message is configured to comprise a second value that indicates that the system is not able to support modification of the first number of additional demodulation reference signal positions after the attaching to the system;
facilitating first broadband cellular communications between the user equipment and core network equipment that is part of a core network according to the first number of additional demodulation reference signal positions that are configured in radio resource control information;
determining to modify the first number of additional demodulation reference signal positions;
based on determining to modify the first number of additional demodulation reference signal positions, sending, to the user equipment, physical downlink control channel downlink control information that indicates a second number of additional demodulation reference signal positions that are configured in the downlink control information; and
facilitating second broadband cellular communications between the user equipment and the core network equipment according to the second number of additional demodulation reference signal positions.
