[0035] In some embodiments, the flight path information may include at least one of the following parameters: waypoint locations and / or timestamp information. In some embodiments, the waypoint locations are a type of location coordinates. In some embodiments, the waypoint locations include location coordinates of one or more corresponding UAVs. In some embodiments, the timestamp information includes absolute time information. For example, the absolute time information may be in the format of YY-MM-DD HH:MM:SS, where YY indicates the year, MM indicates the month, DD indicates the day, HH indicates the hour, MM indicates the minute, and SS indicates the second.

[0036] In some embodiments, the flight height information includes information regarding the height of one or more corresponding UAVs above sea level.

The UAV distinguishing information includes at least one of a planned communication time, a stationary instruction, a power consumption level, flight path information, or flight height information; and / or the UAV information is sent in a Radio Access Network (RAN) Configuration Update message, a Handover Required message, a Path Switch Request message, a Protocol Data Unit (PDU) Session Resource Modify Indication message, an Initial User Equipment (UE) Message message, or an Uplink Non-access stratum (NAS) Transport message; and / or The UAV grouping information is sent in a RAN Configuration Update Acknowledge message, a Handover Command message, a Path Switch Request Acknowledge message, a PDU Session Resource Modify Confirm message, or a Downlink NAS Transport message; and / or 8. The wireless communication method of claim 7, wherein the second wireless communication node is configured to transmit UAV-related information to a third wireless communication node, the UAV-related information including at least one of a group identifier, a UAV group authorization information, a UAV identifier, or a UAV distinction information, optionally the UAV-related information being transmitted in a Next Generation Radio Access Network (NG-RAN) Configuration Update message, a Handover Request message, or a Retrieve UE Context Request message, and further optionally the second wireless communication node is configured to receive a response message from the third wireless communication node, the response message being transmitted in an NG-RAN Configuration Acknowledge message, a Handover Request Acknowledge message, or a Retrieve UE Context Response message.

9. 1. A wireless communication method implemented in a 5G network, comprising: receiving, by a third wireless communication node, UAV-related information from the second wireless communication node to the third wireless communication node, the UAV-related information including at least one of a group identifier, a UAV group permission information, a UAV identifier, or a UAV distinction information; The wireless communication method, wherein the UAV group permission information indicates whether UAVs are permitted to operate in groups.

10. The UAV distinguishing information includes at least one of a planned communication time, a stationary instruction, a power consumption level, flight path information, or flight height information; and / or The UAV-related information is sent in a Next Generation Radio Access Network (NG-RAN) Configuration Update message, a Handover Request message, or a Retrieve User Equipment (UE) Context Request message; and / or 10. The wireless communication method of claim 9, wherein the third wireless communication node is configured to transmit a response message to the second wireless communication node, the response message being transmitted in an NG-RAN Configuration Acknowledge message, a Handover Request Acknowledge message, or a Retrieve UE Context Response message.

11. A communication unit; a processor configured to perform the wireless communication method according to any one of claims 1 to 5; A wireless communication node comprising:

12. A communication unit; a processor configured to perform the wireless communication method according to any one of claims 6 to 8; A wireless communication node comprising:

13. A communication unit; a processor configured to perform the wireless communication method according to claim 9 or 10; A wireless communication node comprising:

14. A computer program which, when executed by a processor, causes the processor to implement the wireless communication method according to any one of claims 1 to 10.
