Abstract: An apparatus, method and computing program is described including: receiving one or more received symbols and one or more received bits, wherein the received symbols are received at a receiver of a transmission system including a transmitter, a channel, and the receiver; converting one or more of the received bits that are deemed to be correct into one or more estimated transmission symbols; generating an estimated channel transfer function based on one or more of the estimated transmission symbols and corresponding received symbols; and providing training data pairs, each training data pair including a first element based on the estimated channel transfer function and a second element based on the corresponding received symbols.

Abstract: An apparatus, method and computer program is described including: generating a channel quality metric offset; summing a channel quality metric and the channel quality metric offset to generate an adjusted channel quality metric of a channel of a mobile communication system; setting a modulation and coding scheme for transmitting data over the channel based, at least in part, on the adjusted channel quality metric; obtaining feedback data relating to the success of data transfer over said channel; compiling a loss/reward function based, at least in part, on said feedback data; and updating a model using the loss/reward function, wherein the model is used in the generation of said channel quality metric offset.

Abstract: It is provided a method, comprising identifying a value of an onsite channel characteristic of a receive channel; requesting a neural network parameter, wherein the request comprises an indication of the onsite channel characteristic; monitoring if the neural network parameter is received in response to the request; estimating the receive channel by a neural network using the neural network parameter if the neural network parameter is received.

Abstract: A method of channel estimation for an antenna array is disclosed. The method includes, receiving a signal transmitted by the antenna array, obtaining a neural network model trained for channel estimation using the received signal, inputting a representation of the received signal into the neural network model and generating a channel estimate for the received signal, and deciding whether to employ a further neural network model for the channel estimation.
