6.7 Timer Tolerances
36.5083GPPCommon test environments for User Equipment (UE) conformance testingEvolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core (EPC)Release 17TS
The timer tolerances specified for the test environment in this subclause apply to all Signalling test cases defined in TS 36.523-1 [18] unless otherwise specified
All the timers used during testing are within a tolerance margin given by the equation below. If for a specific test a different tolerance value is required then this should be specified in the relevant test document (i.e. the document where the test is described).
Timer tolerance = 10%, or 5 × RTT, whichever value is the greater.
Where RTT = 8 TTIs for FDD, and RTT= Maximum RTT from Table 6.7-1 for TDD (see Note).
NOTE: Since the exact RTT for TDD varies depending on the UL/DL configurations and subframe number [29], the maximum RTT is defined in Table 6.7-1.
