Section: 7.3.2.3 Other performance requirements
Content: The 5G system shall be able to provide the 5G positioning services with a TTFF less than 30 s and, for some 5G positioning services, shall support mechanisms to provide a TTFF less than 10 s. NOTE 1: In some services, a TTFF of less than 10s can only be achievable at the expense of a relaxation of some other performances (e.g. horizontal accuracy can be 1 m or 3 m after 10 s TTFF, and reach a steady state accuracy of 0,3 m after 30 s). The 5G system shall support a mechanism to determine the UE's velocity with a positioning service availability of 99%, an accuracy better than 0,5 m/s for the speed and an accuracy better than 5 degree for the 3-Dimension direction of travel. The 5G system shall support a mechanism to determine the UE's heading with an accuracy better than 30 degrees (0,54 rad) and a positioning service availability of 99,9 % for static users and with an accuracy better than 10 degrees (0,17 rad) and a positioning service availability of 99 % for users up to 10 km/h. For power consumption aspects for various usage scenarios see TS 22.104[ Service requirements for cyber-physical control applications in vertical domains ]  [21] Low power high accuary positioning use cases and example scenarios for Industrial IoT devices can be found in 3GPP TS 22.104[ Service requirements for cyber-physical control applications in vertical domains ]  [21].
