Claim 15:
16. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured at least to:
receive, by a first user device in a wireless network, an indication of availability of a pre-trained neural network model that estimates a channel between a second user device and a network node;
receive, by the first user device, information relating to the pre-trained neural network model during a procedure of the first user device to establish a connection to the network node, the receiving the information relating to the pre-trained neural network model comprising:
determining, by the first user device, a current time;
comparing, by the first user device, the current time to the time associated with the pre-trained neural network model;
making a determination, based on the comparing, to obtain at least a portion of the pre-trained neural network model or information relating to the pre-trained neural network model;
transmitting a request to receive the pre-trained neural network model; and
receiving, by the first user device, at least a portion of the pre-trained neural network model from either the network node or the second user device;

determine, by the first user device, channel estimation information based at least on the information relating to the pre-trained model; and
perform at least one of the following:
transmit, by the first user device, a report to the network node including the channel estimation information; or
receive data, by the first user device from the network node, based on the channel estimation information.
