Method and device in communication node for wireless communication

Technical field

In the future, the application scenarios of wireless communication systems become more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of multiple application scenarios, it was decided at the plenary meeting of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network, radio access network) #72 that the new radio technology (NR , New Radio (or 5G) conducted research, passed the New Radio Technology (NR, New Radio) WI (Work Item) at the 3GPP RAN#75 plenary meeting, and began to standardize NR.

In order to be able to adapt to diverse application scenarios and meet different needs, the research project of Non-Terrestrial Networks (NTN, Non-Terrestrial Networks) under NR was also passed at the 3GPP RAN#75 plenary meeting, which started in version R15.

Since the distance from the satellite or aircraft to the user equipment is much greater than the distance from the ground base station to the user equipment, the satellite or aircraft is Propagation Delay during communication and transmission between user equipment. In addition, when the satellite is used as the relay device of the ground station, the delay of the feeder link between the satellite and the ground station will further increase the transmission delay between the user equipment and the base station. On the other hand, because the coverage of satellites and aircraft is much larger than that of terrestrial networks (Terrestrial Networks), and the inclination angles of ground equipment to satellites or aircraft are different, the difference between the delays in NTN is very large. .
