A base station can cause a multitude of user devices in a network to be synchronized with the base station's clock using an ultra-lean low-complexity procedure in 5G or 6G. On a predetermined interval, the base station can transmit a timing signal in the guard-space of a predetermined resource element. The timing signal is a 180-degree phase reversal of the cyclic prefix centered in the guard-space. Each user device can receive the timing signal, determine how far the received timestamp point is from the middle of the guard-space (as viewed by the user device), and thereby determine a timing error between the user device clock and the base station clock, and correct the user device clock accordingly. In addition, the user device can average the timing adjustments over a number of instances, thereby determining a frequency offset if the average differs significantly from zero, and thereby adjust the clock frequency.

Multiple regions around a cell tower provide coverage to a UE. The multiple regions describe the location of the UE in relation to the cell tower. The multiple regions include a near region and a far region. The system sends a request to the UE to provide an indication of a distance between the UE and the cell tower. Based on the distance between the UE and the cell tower, the system categorizes the location of the UE in relation to the cell tower into one of the multiple regions. The system receives an indication of a problem in a communication between the UE and the wireless telecommunication network. Based on the one of the multiple regions into which the location of the UE is categorized, the system determines a likely source of the problem such as the UE, a radio network, or a core network.
