M.6 Assistance data required for testing

3GPP45.005GSM/EDGE Radio transmission and receptionTS

M.6.1 Introduction

This clause defines the assistance data IEs available in all test cases. The assistance data shall be given for satellites as defined in subclause M.3.1.5.

The information elements are given with reference to 3GPP TS 44.031, where the details are defined.

Subclause M.6.2 lists the assistance data IEs required for testing of MS-based mode, and subclause M.6.3 lists the assistance data available for testing of MS-assisted mode.

M.6.2 Information elements required for MS-based
