E.1 Introduction
38.1713GPPNRRelease 17Requirements for Support of Assisted Global Navigation Satellite System (A-GNSS)TS
This annex defines the assistance data IEs available at the SS in all test cases. The assistance data shall be given for satellites as defined in B.1.5.
The information elements are given with reference to TS 36.355 [3], where the details are defined.
Table E.1 defines the assistance data elements which shall be provided to the UE in the tests (steps (d) and (e) in the message sequence according to annexes D.2 and D.3). The assistance data provided depends on the mode being used in the test case, the assistance data supported by the UE (indicated in step (c) in the message sequence according to annexes D.2 and D.3) and the GNSSs supported by the UE. Assistance data IEs not supported by the UE shall not be sent. Assistance data IEs supported by the UE but not listed in Table E.1 shall not be sent.
