Online adjustment for channel state information

A method for wireless communications at a base station, comprising:

• receiving, from a user equipment (UE), one or more sounding reference signals for an uplink channel;
• measuring one or more first channel state parameters of the one or more sounding reference signals;
• decoding one or more uplink transmissions received from the UE;
• determining, using one or more signal processing operations and based at least in part on one or more preprocessed decoder parameters, one or more adjustment values for the one or more first channel state parameters;
• and
• transmitting, to the UE, the one or more adjustment values for the one or more first channel state parameters.

A method for wireless communication at a user equipment (UE), comprising:

• determining one or more channel state parameters associated with one or more reference signals communicated over a channel;
• detecting, from a downlink channel decoder, one or more preprocessed decoder parameters associated with communication over the channel;
• and
• transmitting, to a base station, a message comprising an indication of the one or more preprocessed decoder parameters based at least in part on determining the one or more channel state parameters and detecting the one or more preprocessed decoder parameters.

A method for wireless communications at a base station, comprising:

• determining one or more channel state parameters associated with one or more reference signals communicated over a channel;
• receiving, from a user equipment (UE), a message comprising an indication of one or more preprocessed decoder parameters associated with a downlink channel decoder of the UE;
• determining, based at least in part on the indication of the one or more preprocessed decoder parameters, one or more adjustment values associated with the one or more channel state parameters;
• and
• transmitting, to the UE, a downlink transmission based at least in part on the one or more adjustment values associated with the one or more channel state parameters.
