14 Timing Accuracy
25.1163GPPRelease 17TSUTRA repeater radio transmission and reception (LCR TDD)
Timing Accuracy is the repeater synchronization accuracy with NodeB, it includes the downlink ramp on/off time and uplink ramp on/off time.
14.1 Minimum requirement
The downlink gain versus time should meet the mask specified in figure 14.1. The beginning and end point of downlink burst is calculated according to the trigger given by NodeB or LCR TDD signal generator.

The uplink gain versus time should meet the mask specified in figure 14.2. The beginning and end point of uplink burst is calculated according to the trigger given by NodeB or LCR TDD signal generator.

Annex A (normative):
Environmental requirements for the Repeater equipment
The Repeater equipment shall fulfil all the requirements in the full range of environmental conditions for the relevant environmental class from the relevant IEC specifications listed below
60 721-3-3 "Stationary use at weather protected locations" [6];
60 721-3-4 "Stationary use at non weather protected locations" [7]
Normally it should be sufficient for all tests to be conducted using normal test conditions except where otherwise stated. For guidance on the use of test conditions to be used in order to show compliance refer to TS 25.153.
Annex B (informative):
