There are several types of mutual interference among frequency-sharing systems: (1) interference among terrestrial stations; (2) interference between satellite–earth links; and (3) interference between terrestrial stations and earth stations.
Existing research focuses on interference between LTE and other communication systems in various frequency bands, with the majority of them examining interference between LTE-FDD, TD-LTE, NR-FDD, TD-SCDMA, and DVB-T system cells caused by base stations.
Unless otherwise specified, all base stations use the same frequencies. Users associate to the base station from which they receive the strongest signal, and transmission rates are selected, in each subframe, according to the Signal-plus-Noise Interference Ratio (SINR), see Table 5.1. The SINR for a certain user u = 1 : : : k is defined as follows:
In this article, we establish a DL mutual interference model of adjacent ISAC base stations, and analyze the relationship between the communication and sensing mutual interference channels.
Simulation results demonstrate that adjacent frequency user equipment (UE) has negligible small interference with the LTE-M underground system when using the leaky cable radiation pattern, whereas for the LTE-M ground system, the main interference comes from the adjacent frequency UE to the LTE-M base station (BS).
As for interference among terrestrial stations (noncellular, non-PCs, and nonsatellite), in the lower part of the frequency spectrum (<200 MHz), most of the terrestrial services do not suffer from interference problems. Mutual interference that could exist has been limited to acceptable levels by good frequency planning.
