Abstract: To assist a user device of a 5G or 6G network in finding its downlink messages, the base station can attach a leading and trailing demarcation to the message. The user device can recognize the demarcations, extract the data between them, and thereby receive the message without computation-intensive searching. Advantageously, the user device can request that the base station not transmit DCI (downlink control information) messages to the user device, since the user device can readily find its messages according to the demarcations. In various embodiments, the demarcations can indicate the address or identity of the intended recipient, the length of the message, the type of the message, and other information to assist the user device. In addition, for even easier detection of the demarcations, the base station can insert a gap of no transmission before and/or after each demarcation. Such demarcations may enable low-cost reduced-capability user devices.
