Allocation of channel information transfer enhancing massive MIMO uplink in split RAN deployments

A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:

• receiving sounding reference signal (SRS) data for an uplink transmission of a user equipment (UE) from a remote unit (RU);
• determining a signal to interference and noise ratio (SINR) associated with an SRS from the SRS data resulting in a first determination;
• based on the first determination, determining that the SINR does not satisfy an SRS SINR threshold resulting in a second determination;
• based on the second determination, generating SRS-based channel estimates from the SRS data;
• transmitting the SRS-based channel estimates to the RU;
• instructing the RU to calculate demodulation reference signal (DMRS) channel estimates from the SRS-based channel estimates and subsequent uplink transmissions of the UE;
• instructing the RU to provide the DMRS channel estimates;
• and
• processing the uplink transmission using the DMRS channel estimates received from the RU.

A method, comprising:

• receiving, by a processing system including a processor, sounding reference signal (SRS) data for an uplink transmission of a user equipment (UE) from a remote unit (RU);
• determining, by the processing system, a signal to interference and noise ratio (SINR) associated with an SRS from the SRS data resulting in a first determination;
• based on the first determination, determining, by the processing system, that the SINR does not satisfy an SRS SINR threshold resulting in a second determination;
• based on the second determination, generating, by the processing system, SRS-based channel estimates from the SRS data;
• determining, by the processing system, whether to transmit the SRS-based channel estimates to the RU resulting in a third determination;
• responsive to the third determination to transmit the SRS-based channel estimates to the RU, instructing, by the processing system, the RU to calculate demodulation reference signal (DMRS) channel estimates from the SRS-based channel estimates and subsequent uplink transmissions of the UE;
• instructing, by the processing system, the RU to provide DMRS channel estimates;
• and
• processing, by the processing system, the uplink transmission using the DMRS channel estimates received from the RU.
