Section: 7.3 Decentralised UAV traffic management
Content: The 3GPP system shall enable a UAV to broadcast the following identity data in a short-range area for collision avoidance: [UAV type, current location and time, route data, operating status]. The 3GPP system shall enable UAV to broadcast the identity information which preserves the privacy of the owner of the UAV and the UAV operator. The 3GPP system shall enable a UAV to receive local broadcast communication transport service from other UAV in short range. A UAV shall be able to use a direct UAV to UAV local broadcast communication transport service when served or not served by a 3GPP network. A UAV shall be able to use a direct UAV to UAV local broadcast communication transport service when served or not served by the same 3GPP network. The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service at relative speeds of up to 320kmph. The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service at absolute speeds of up to 160kmph. The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service with variable message payloads of 50-1500 bytes, not including security-related message component(s). The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service which can maintain a separation distance between two UAVs of greater than 50m. The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service which supports a range of up to 600m The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service which supports a range sufficient to give the UAVs ample time to perform manoeuvres to maintain a separation distance of 50m (e.g. 6.5 seconds). The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service which can transmit messages at a frequency of at least 10 messages per second. The 3GPP system shall support a direct UAV to UAV local broadcast communication transport service which can transmit messages with an end-to-end latency of at most 100ms. The 3GPP system shall be able to support direct device connection between UAVs to transmit messages to identity the UAVs. Editor’s note: It is FFS up to which distance the direct device connection needs to support The 3GPP system shall be able to support a UAV to transmit a message to identity the UAV via direct device connection in addition to network connection. The UAS shall be able to locally broadcast its identity and location. NOTE: the locally broadcast information should not expose personally identifiable information to general users. The UAS shall be able to locally broadcast its identity via local broadcast with a rate of at least once per 1s. The UAS shall be able to locally broadcast its identity up to a range of 500m.
