The 5G system shall be able to provide unmanned aerial vehicle with the service performance requirements reported in Table 7.1-1.
UAV originated QoS in the table refers to the QoS of Uplink data (e.g. from UAV to the network side). UAV terminated QoS is the QoS of downlink data (e.g. from the network side to UAV).
The data transmitted by the 5G system includes data collected by hardware devices installed on UAV such as cameras, e.g. pictures, videos and files. It is also possible to transmit some software calculation or statistical data, e.g. UAV management data. The service control data of transmitted by the 5G system may be based on application triggers, such as switch, rotation, promotion and demotion control of equipment on UAV. Various UAV applications may require different uplink and downlink QoS at the same time. The 5G system may simultaneously provide services to other users on the ground (e.g., the KPIs for rural and urban scenarios as defined in clause 7.1 of TS 22.261) in the same area without service degradation.
UAVs may use a variety of flight command and control modes. Command and control (C2) communications refers to the two-way communication, which may include video, required to control the operation of the UAV itself. C2 messages may be communicated with the UAV controller, the UTM or both and may or may not be periodic. UAV controller and UTM communications may happen at essentially the same time with different required QoS. Any mission specific communication (e.g. HD video for area surveillance), if required, is additional. Different modes of control and their typical KPIs are listed in this clause below. The 5G system shall support UAV operation at altitudes of at least 120m / 400ft above ground level, e.g. the services should be provided and characterized up to 3000ft AGL.
The 5G system shall support a mechanism to switch between C2 communication modes for UAS operation, e.g. from indirect C2 communication to direct C2 communication, and ensure the disconnect time is below the latency requirements.
The 3GPP system shall enable concurrent communications between the UAV-controller and UAV and between the UTM and the UAV that may require different KPIs.
The 3GPP system shall be capable of switching between the KPIs, as requested by the UAV-controller or the UTM, within [500ms].
