Combined Downlink Demarcations and Demodulation References in 5G/6G

A method for a base station of a wireless network, the method comprising:

• a) receiving, from a user device of the wireless network, a request message requesting that a leading demarcation and a trailing demarcation be concatenated with downlink messages to the user device, and that downlink control information (DCI) messages not be transmitted to the user device;
• and
• b) then, without transmitting a DCI message to the user device, transmitting a downlink message to the user device, the downlink message prepended by the leading demarcation and appended by the trailing demarcation;
• c) wherein the leading demarcation comprises a first gap with no transmission, followed by a first demodulation reference, followed by a second gap with no transmission;
• and
• d) wherein the trailing demarcation comprises a second demodulation reference different from the first demodulation reference, concatenated immediately to the message without a gap.

A method for a user device of a wireless network, the user device comprising a processor containing an artificial intelligence (AI) model, the method comprising:

• a) configuring or training the AI model to identify downlink control messages in a received signal;
• b) providing, as input to the AI model, signals of a downlink channel of the wireless network;
• c) determining, as output from the AI model, a predetermined leading demarcation and a predetermined trailing demarcation;
• d) according to the AI model, demodulating, or attempting to demodulate, data between the leading and trailing demarcations;
• and
• e) determining, according to the AI model, that the data between the leading and trailing demarcations comprises a downlink message addressed to the user device;
• f) wherein the leading demarcation indicates a length of the downlink message, and the trailing demarcation indicates a message type of the downlink message.
