Coverage Solution for Airspace Routes in Low Altitude Network

To ensure ground coverage performance of the existing ground base station, a certain down tilt angle is set for the antenna, and a rear lobe points to a low-altitude space domain. According to the current low-altitude network spatial domain test, radio signals in the low-altitude spatial domain are disordered and overlapped. Under the same RSRP level, the SINR of radio signals is lower than that of the ground. In addition, low-altitude network service requirements are not clear. Therefore, low-altitude airspace is covered according to the existing ground network planning method, resulting in a low return on investment. This paper proposes a low altitude network airspace coverage method based on low altitude route, planning vectored low altitude route, judging the coverage performance of ground base stations to the route, coordinating ground base station beams, screening effective ground base station beams in the target airspace of low altitude network that can meet service requirements, For the target airspace that does not meet the service requirements, the ground base station near the route is used to add a new airspace-oriented beam, to achieve the low-altitude airspace coverage performance of the target route to meet the requirements.
