8.5.11a CELL_DCH measurement occasion calculation (1.28 Mcps TDD only)

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

In CELL_DCH state, when the CELL_DCH measurement occasion pattern sequence(s) is(are) configured and activated for the specified measurement purpose as specified in the subclause 8.6.7.26, then the UE shall perform corresponding measurements as specified in subclauses 8.4.1.7 and 8.4.1.8 during the timeslot(s) indicated by IE: "Timeslot Bitmap" within the frames from the frame SFN_start to SFN_start + M_Length -1 frame belong to the allocation with SFN_start fulfilling the following equation:

SFN_start mod (2^k) = offset

where

– k is CELL_DCH measurement occasion cycle length coefficient and signalled by the IE "k" in the IE "CELL_DCH measurement occasion info LCR". The actual measurement occasion period equal to 2^k radio frames.

– Offset is the measurement occasion position in the measurement period. and signalled by the IE "Offset" in the IE "CELL_DCH measurement occasion info LCR".

– M_Length is the actual measurement occasion length in frames starting from the Offset and signalled by the IE "M_Length" in the IE "CELL_DCH measurement occasion info LCR".
