Neural network-assisted generation of interleaver in wireless communication system

A User Equipment (UE) in a wireless communication network, comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the UE at least to:
• receive an encoded control message from a network node over a wireless communication channel, the encoded control message comprising an interleaved set of bits, the wireless communication channel having a channel status;
• decode the encoded control message to retrieve the interleaved set of bits;
• generate an interleaver by using a Neural Network (NN), the NN being pre-known to both the UE and the network node, the NN being configured to receive the channel status of the wireless communication channel and a connection status of the UE in the wireless communication network as input data and output the interleaver, the interleaver being an orthogonal binary matrix;
• generate a deinterleaver by applying a transpose operation to the generated interleaver;
• and
• deinterleave the interleaved set of bits by using the generated deinterleaver.

A method for operating a network node in a wireless communication network, comprising:

• generating a control message to be transmitted to a User Equipment (UE) over a wireless communication channel, the control message comprising a set of bits, the wireless communication channel having a channel status, and the UE having a connection status in the wireless communication network;
• generating an interleaver by using a Neural Network (NN), the NN being pre-known to both the network node and the UE, the NN being configured to receive the channel status of the wireless communication channel and the connection status of the UE as input data and output the interleaver, the interleaver being an orthogonal binary matrix;
• interleaving the set of bits in the control message by using the generated interleaver;
• encoding the control message comprising the interleaved set of bits;
• and
• transmitting the encoded control message to the UE over the wireless communication channel.
