Unequal density demodulation reference signal positions

A method, comprising:

• determining, by a system comprising a processor, to facilitate broadband cellular communications with a user equipment;
• determining, by the system, to communicate an uplink portion of the broadband cellular communications according to a first group of differing demodulation reference signal densities, wherein communicating a downlink portion of the broadband cellular communications is performed according to a second group of demodulation reference signal densities different from the first group of differing demodulation reference signal densities;
• communicating, by the system, the first group of differing demodulation reference signal densities to the user equipment;
• after communicating the first group of differing demodulation reference signal densities to the user equipment, communicating, by the system, the uplink portion of the broadband cellular communications with the user equipment according to the first group of differing demodulation reference signal densities;
• and
• communicating, by the system, the downlink portion of the broadband cellular communications with the user equipment according to the second group of demodulation reference signal densities.

A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising at least one processor to perform operations, comprising:

• as part of broadband cellular communications with a user equipment, determining to conduct uplink communications of the broadband cellular communications according to a first group of differing demodulation reference signal densities;
• communicating the first group of differing demodulation reference signal densities to the user equipment;
• after communicating the first group of differing demodulation reference signal densities to the user equipment, conducting the uplink communications of the broadband cellular communications with the user equipment according to the first group of differing demodulation reference signal densities;
• and
• conducting downlink communications of the broadband cellular communications with the user equipment according to a second group of demodulation reference signal densities, wherein the first group of differing demodulation reference signal densities differs from the second group of demodulation reference signal densities.
