Abstract
A method of wireless communication by a user equipment (UE) indicates, to a base station, a training state of a machine learning model for a given channel condition, and a request for a change in demodulation reference signal (DMRS) transmissions. The UE also receives DMRS transmissions in accordance with the training state for the given channel condition. The UE performs online training of the machine learning model with the DMRS transmissions. A UE may also request, from a base station, a specific number of demodulation reference signal (DMRS) symbols for a slot, and receive DMRS transmissions in response to the request to estimate a raw channel.
Claims50
